Q43. Can a Forgery Expert Determine Who Signed Someone Else’s Name?
Can a Forgery Expert Determine Who Signed Someone Else’s Name?
I get this one a lot. A client will say, “I understand a forensic document examiner can tell whether a signature was forged. Can you tell us who did the forging?”
It’s a great question. And here’s the honest truth I’ve found over the years: it’s harder to identify who committed the forgery than to rule out the person who didn’t.
Picture a simple case. There’s an old VW Bug, the owner has passed away, and her kids are fighting over the title. In my office, we might conclude, “The decedent — the woman who died — did not sign this title.” When I know that for certain, I’m comfortable saying it. The complication is that there are five kids, and one of them is probably the suspect. We can look at all their handwriting and form a view about which one most likely signed it.
Why Identifying the Forger Is Harder Than It Sounds
That works well when the forger wrote naturally. Not all of them do. Think about the art-thief version of a forgery — someone carefully mirroring or simulating a signature. They’re not going to leave much trace of their own natural writing. The result looks more like an imitation than a genuine sample, which makes pinning down the forger’s own characteristics nearly impossible.
So from the handwriting alone, we usually can’t name who committed the forgery. The surrounding circumstances tend to point at the culprit, and that’s what helps the court or the police identify them.
A Case Where We Could Identify the Forger
There was a case in Tyler, Texas, where an entire three-page will was supposedly written in the grandmother’s hand. It clearly was not. I prepared a report concluding two things — that the will wasn’t the grandmother’s writing, and that it was, in fact, written by the niece.
Here’s how I knew. She did a poor job copying her grandmother’s handwriting, and the whole thing looked an awful lot like her own natural hand. She had no idea handwriting experts even existed. She also had no idea the police would knock on her door. The report was persuasive enough that the police called to confirm it was real, then arrested her and charged her with forgery and attempted theft of an estate. It started as a civil case and turned criminal.
Handwriting can be used to prosecute. In that one I could identify the forger because I had a full page of her writing — enough that her natural tendencies surfaced. From a signature alone, your best bet is to verify authenticity first, and then look at who stood to benefit, because that person usually had a hand in creating the document.
When to Let the Investigators Take Over
My job is to tell the truth about what the ink on the page reveals. Everything past that — the full investigation, the prosecution, the final judgment — belongs to the detectives, the district attorney, and the court. In most cases the handwriting is just one piece of a much larger puzzle.
If you suspect a document in your case has been forged, that’s exactly the kind of analysis we do. Reach out and we’ll help you figure out what the evidence actually shows.

Frequently Asked Questions
Can a forgery expert determine who forged a signature?
It is usually harder to identify who committed a forgery than to rule out the person who did not. From the handwriting alone, an examiner often cannot name the forger — the surrounding circumstances are what typically point investigators to the culprit.
Why is it difficult to identify a forger from handwriting alone?
A careful forger who mirrors or simulates another person’s signature leaves very little of their own natural writing behind. The result looks like an imitation rather than a genuine sample, which makes the forger’s own handwriting characteristics nearly impossible to pin down.
Can a forger ever be identified by a handwriting expert?
Yes, when enough of the forger’s natural writing surfaces. In one Tyler, Texas case, a three-page will was poorly copied and closely resembled the niece’s own handwriting. The examiner’s report concluded she wrote it, and she was arrested and charged with forgery and attempted theft of an estate.
What should you do if you suspect a forged document?
Verify the document’s authenticity first with a forensic document examiner, then look at who stood to benefit, because that person usually had a hand in creating it. The full investigation and prosecution belong to the detectives, the district attorney, and the court.

Q39. Can a Handwriting Expert Compare Two Signatures and Determine Which One Is Real?
Can a Handwriting Expert Compare Two Signatures and Decide Which One Is Real?
Yes and no. Deciding whether a signature is genuine or forged is the heart of what a forensic handwriting expert does. But the question hides an assumption — that you only have one signature to compare against.
In a real case, you almost never do.
Say the questioned signature sits on a deed, a deed of trust, or a will. In most courtroom matters you’ll have twenty or more comparison documents to work from — samples pulled from a passport, a birth certificate, a driver’s license. You gather all of those so the examiner can map out the person’s range of natural variation.
Why More Samples Make a Stronger Opinion
I’m not saying one-to-one is impossible. I’ve seen cases where a single comparison was enough to form an opinion. But the better, more scientific path is one-to-many, because that’s how you establish the range a person’s own hand moves through.
Think about the math of it. If you’re going to spend $5,000 or $10,000 on an expert witness and another $30,000 on a lawyer, do it right. Hire a private investigator. Dig through the trash if you have to. Find more handwriting samples — in the lawsuit, in the courthouse files for a Tarrant County probate matter, wherever they live.
You don’t want your expert wrestling for hours over three samples when twenty were sitting there for the asking. A hundred samples sounds like a lot of work, and it is. But with a hundred originals in front of me, my opinion is stronger, I’m a better witness, and I have more confidence in what we’re telling the jury. With one or three signatures, it slides onto a probability scale — here’s what I can see, but I can’t tell you what’s behind door number three. More evidence is always better.
What About Voter Fraud Cases?
Voting cases are their own problem, because you usually can’t get a large pool of comparison signatures. You can’t pull a sample from every voter in a Collin County precinct — it’s not a will-and-testament file with a tidy paper trail. People call and say, “We think there’s voter fraud, there are 24,000 ballots,” and then in the same breath, “We can’t afford you.” At that scale, cutting corners isn’t an option if you want results you can trust.
So the caller offers the voter registration card and its one signature. That’s not very scientific. Honestly, someone like me could do a decent first pass with two signatures and be fairly accurate. What worries me is the bigger picture — in a lot of places, people with almost no training are throwing out ballots because they decided the signatures don’t match. How would they even know?
Without proper training, there’s no reliable way to tell a genuine mismatch from ordinary natural variation in someone’s hand. Luckily, I haven’t heard of many places in America where voting was profoundly affected this way. The big disputes you read about tend to be machine-tabulation issues, not signature calls — that famous Bush recount was a counting-machine problem. But signatures are still being rejected by amateurs who’ve had as little as one hour of training, and they really shouldn’t hold that power.
Even with my training, one comparison signature is enough to say “probably the same person” or “probably not.” I’d still rather add another layer of research with more examples.
So, to answer the original question plainly: yes, you can compare one signature to another and form an opinion about whether it’s fake. I’d just rather have a little more evidence in hand.

Frequently Asked Questions
Can a handwriting expert compare just two signatures?
Yes — you can compare one signature to another and form an opinion about whether it is fake. But the better, more scientific path is one-to-many, because comparing against many samples establishes the range a person’s own hand naturally moves through.
How many comparison signatures does an examiner want?
In most courtroom matters there are twenty or more comparison documents — samples pulled from a passport, birth certificate, or driver’s license. With a hundred originals the opinion is stronger and the expert is a more confident witness; with one or three it slides onto a probability scale.
Why is natural variation important in signature comparison?
Every person’s hand moves through a range of natural variation. Without proper training there is no reliable way to tell a genuine mismatch from ordinary variation — which is why amateurs with as little as one hour of training should not be rejecting signatures.
What makes voter signature verification difficult?
You usually cannot get a large pool of comparison signatures — often just the voter registration card with one signature, which is not very scientific. A trained examiner can do a decent first pass with two signatures, but more evidence is always better.

Q38. How Fast Can a Handwriting Expert Help Win a Court Case?
How Fast Can a Handwriting Expert Help Win a Court Case?
We hear this one a lot. How quickly can a handwriting expert step in and help with a court case? The question itself assumes speed is the priority — you’re in court today, a document lands in front of you, and suddenly it’s, “We need a handwriting expert, now.”
It’s tough to have an expert start, examine, write the report, and finish inside 24 hours. And if it’s possible at all, you’re looking at two- or three-times rush fees.
We also never agree to testify before we’ve done the work. A client might call and say, “Great, let me pay you for court.” Wait a second. You don’t yet know whether my opinion helps you, because you’re not hiring an expert witness to deliver the opinion you want.
Some people think that’s what they’re hiring for. But every expert witness I respect operates on integrity. We’ll say, “I’ll do the investigation. If I determine the signature is authentic — or that it isn’t — then and only then will I take your money to go to court. I can’t testify to something I don’t believe.”
Why Rushing an Expert Is Risky
For most cases, we like six or eight weeks of lead time so we can collect all the evidence. We don’t want to take a thin case and then get pushed into trial.
We can move fast when we have to, but it’s not our preference. We don’t want to be rushed, we don’t want to be biased, and we want time to do it right. Our job as forensic handwriting expert witnesses is to tell the truth, let the evidence speak, and tell the judge exactly what we found.
If your case feels genuinely urgent, get on the phone with both an attorney and a forensic expert. Be ready to pay rush fees, and ask the real questions: How fast can you turn it around? How fast can I get you the evidence? Can you move other cases? Are you in court that week?
In my experience, the urgency a client feels on the phone doesn’t always match the actual timeline. They’ll say, “Three weeks? You can’t take three weeks.” A busy forensic office may have a dozen or more active cases at any given time.
We have offices in Miami, Dallas, Nashville, and around the country, so there’s probably an expert near you — here in Dallas–Fort Worth, that’s us. If that expert isn’t in court over the next few days, they may be able to spend those days on your case and turn it quickly. If your deadline is Friday and it’s Monday, we can probably get to it. What we can’t do is guarantee you an outcome.
What If You’re Already in Court?
Yes, we can still help. But if you’re mid-case and the other side presents evidence, you’ve got logistical problems — and a lot depends on how good your attorney is at designating a witness. In some states, you can’t designate a witness the same day.
You can designate a rebuttal witness, and that can matter a great deal. If they say, “We have this contract no one’s ever seen,” you can respond, “That’s not true.” That’s a rebuttal witness, and it’s an option.
But if that piece of paper has sat in your file for a year and a half, unquestioned, and now you want an expert — the other side can object. “You’ve had two years to hire and designate an expert. We need to know who this is. We need to depose him, see his evidence, see his report.” Getting someone hired by the next business day may simply not be feasible. That’s the danger of waiting too long.
The Bottom Line: Don’t Wait
If you think a case might head to court — say, a Tarrant County dispute over a contested document — and you may need a forensic document examiner, do it now. Hire them now. Let them do the work. Get their opinion.
If the opinion helps you, you can designate them. That gives the other side time to object and to take depositions. And by the time the court date arrives, your expert has already been vetted, already been approved, and can stand up and present the findings to the jury clearly and credibly.

Frequently Asked Questions
How quickly can a handwriting expert turn around a case?
Finishing an examination, report and all, inside 24 hours is tough — and if it is possible at all, expect two- or three-times rush fees. For most cases the preference is six or eight weeks of lead time so all the evidence can be collected properly.
Will an expert agree to testify before doing the examination?
No. Reputable experts never agree to testify before the work is done, because you are not hiring an expert witness to deliver the opinion you want. Only after the investigation determines the signature is authentic — or is not — will the expert take money to go to court.
Can a handwriting expert still help if the trial has already started?
Yes, though there are logistical hurdles. A rebuttal witness can often be designated to answer new evidence, but if a questioned document sat in your file for a long time, the other side can object that they need to depose the expert first.
When should you hire a forensic document examiner?
Now — before the court date. Hire the expert early, let them do the work, and designate them if the opinion helps. By trial the expert has been vetted and approved, and can present the findings to the jury clearly and credibly.

Q37. Can a Document Examiner Prove a Last Will and Testament Is a Fake?
Can a Document Examiner Prove a Last Will and Testament Is a Fake?
Yes, absolutely. My name is Bart Baggett. I’m a forensic document examiner, and I’ve trained dozens of people around the world to do this work too. What we do, at the core, is determine whether a document is fake.
Why Wills Get Contested
A last will and testament — along with trust documents and health directives — is how people make sure their assets reach the right hands after they’re gone. Good estate planning keeps that clear. But when it isn’t clear, or when someone decides to muddy it on purpose, that’s where I come in.
The reason I get hired so often for wills is simple: people are angry. Kids, nephews, ex-girlfriends, ex-wives — angry enough to file an injunction and stand in front of a judge saying, “I want that person’s things. He loved me more.” Sometimes it’s second- or third-generation children: “He wrote me this will and cut all of you out. You guys are jerks.”
More common, though, is the caregiver. The person taking care of the old man or woman says, “You all haven’t been around in years. You’re off in South Dakota. You don’t need the money.” It’s a story I hear constantly — the caregiver who feels uncompensated and overlooked, who talks themselves into believing they deserve more. So they justify it, and they create a fake will. They end up typing “Will” across the documents. A lot goes wrong with wills and testaments.
What a Forensic Examiner Actually Examines
The signature is the main piece of evidence on the signature page — but it’s not the only one. One reason judges and attorneys want me to review every page of a will or trust is that the third or fourth page may have been changed. That’s where the details live: the car, the motorcycle, the Shelby Mustang, the named trustee. The most important details are the ones most likely to be altered.
A page might have been swapped out entirely. So you look at the fonts, the lettering, the age of the paper — even the staple holes.
How the Process Works
If you think a document is forged, you need a forensic document examiner. There’s clear precedent for experts in probate court — it’s very common. In any major city, including here in the Dallas–Fort Worth area, there are probably four or five experts who handle probate work. A Collin County will contest is exactly the kind of matter that draws one in.
Judges appreciate expert testimony because it gives their rulings a sound, evidence-based foundation — one less likely to be overturned on appeal. They like an expert who’s logical, reasonable, and professional, who can say, “Yes, judge. I’ve looked at it. We believe this to be authentic,” or not.
What happens more often than not, at least in my cases, is that the other side just capitulates. Our letters are convincing, our exhibits are strong, our photography is good. The other side quits: “I can’t find a handwriting expert to go against those people, because they did it right.” That’s the whole point. Tell the truth, back it with exhibits strong enough to support it, and you shouldn’t need a second expert.
So ask yourself the real question. If you think someone forged your dad’s will or your mom’s will, or you’re tangled up in a recent estate fight, that’s exactly when you hire a forensic document examiner.

Frequently Asked Questions
Can a document examiner prove a last will and testament is fake?
Yes, absolutely. Determining whether a document is fake is the core of what a forensic document examiner does, and there is clear precedent for expert testimony in probate court — it is very common.
Who typically forges a will?
A frequent pattern is the caregiver who feels uncompensated and overlooked, talks themselves into believing they deserve more, and creates a fake will. Angry relatives — children, nephews, ex-spouses — also contest or fabricate estate documents.
Does an examiner only look at the signature page?
No. Judges and attorneys want every page reviewed because the third or fourth page may have been changed or swapped — that is where details like assets and the named trustee live. Examiners study fonts, lettering, the age of the paper, even the staple holes.
Why do judges value forensic document examiners in will contests?
Expert testimony gives rulings a sound, evidence-based foundation that is less likely to be overturned on appeal. And strong letters, exhibits, and photography often convince the other side to capitulate before trial.

Q36. Can a Handwriting Expert Prove a Signature Was Forged on a Contract?
Can a Handwriting Expert Prove a Signature Was Forged on a Contract?
Our office gets calls about contract fraud all the time. Can a signature expert prove a signature was forged on a contract? Absolutely. That’s exactly what a forensic document examiner does. Here’s a closer look at how the process really works.
What a Forensic Document Examiner Actually Does
You might call the person who checks a signature’s authenticity a handwriting expert. More precisely, it’s a “forensic handwriting expert” — but the technical term is forensic document examiner. The specialty is handwritten items.
When a disputed signature comes in, we compare it against around 40 other samples of that person’s signature from the last five or six years — ideally from the same general time period as the document in question.
What We Look For
If the case were mine, I’d run a side-by-side analysis. I’d pull out a microscope and zoom in. I’d study the little ink striations inside the ink blobs. I’m asking one core question: does this appear to be the same hand — the same physiology and neurology — that signed all the others?
There are many telltale signs of forgery. I won’t list them here, because I’d rather forgers not know exactly what we’re looking for. In broad terms, we’re reading the writing for signs of forgery or signs of genuineness. Spotting them takes real expertise. It’s a lot harder than glancing at a signature and saying “that looks a little off.” Every micro-movement of the pen has to be analyzed.
A Rare Skill — and How to Find It
Forensic document examiners typically charge $600 or $700 an hour. This is a rare skill. Only a few hundred people in the world can accurately determine a person’s identity from their handwriting. They’re certified or court-qualified forensic document examiners.
If you need one — say, for a Tarrant County contract dispute — I still take cases, especially high-stakes ones, and I refer plenty of others to my associates. Give us a call and we’ll help you figure out whether a handwriting expert is really what your case needs. And if it is, I suspect we have one in your budget.

Q35. How Long Does a Handwriting Investigation Take?
How Long Does a Handwriting Investigation Take?
It’s one of the first things a new client asks when they call. And the honest answer is always the same: it depends.
Mostly it depends on the evidence. Do we have all the documents on day one, or do we wait two weeks while the client digs through boxes, the attic, and the bank vault to pull the samples? What we really need is the evidence — and then that evidence organized.
A Basic Case, Start to Finish
Take a simple one. “Here’s a last will and testament. We don’t know whether the decedent actually wrote and signed this holographic will.” That’s about as basic as it gets. So how long?
If I could walk into the courthouse tomorrow and look at the original, I might have an opinion that same day — the analysis is something I’ve done countless times. But that’s rarely how it goes. In California, you need a judge to sign off before a third party can handle an original document. In Texas, you don’t. Florida and New York have their own rules. So a Tarrant or Dallas County matter can move faster on that front than a California one.
If you don’t have originals and you can email or upload them to my staff, we can normally turn a case around in about 7 to 14 days — as long as everything is organized and printed. My part is fast. I’ve been doing this a long, long time, so when things are organized I might only spend four to six hours on a case from start to finish. But that’s usually spread across a two-, three-, or seven-day window, depending on how quickly the documents come in.
It Takes As Long As the Truth Takes
So how long does it really take? It takes as long as it takes to get the right answer — the honest truth. Writing the report, building the exhibits, and consulting with the attorney all add time on top of the analysis itself.
Here’s my real advice. If you have a lawsuit and you’re thinking about hiring me, or someone like me, do yourself a favor and give us a three-month window. Enough time to investigate, gather the documents, and organize everything. Even once you have an opinion, you’re probably a month from trial. And most trials that get booked end up rebooked — somebody gets a continuance, somebody can’t make the date.
Trials run long. I’ve got a case from around 2021 that’s finally going to court next week in Florida. Almost five years. Sometimes it stretches that far, especially the cases that got stuck during COVID.
So it takes as long as it takes. But if you want to save money, give yourself about three weeks of runway. Do a true rush — “here are the documents, I’m in court tomorrow” — and everyone in this industry charges you double. We have to drop everything, put staff on overtime and weekends to get you an opinion, the lab reports, the notes, and the testimony prep. It’s a lot of work. Give an expert enough time to do the job, and you won’t pay twice for it.

Frequently Asked Questions
How long does a handwriting investigation take?
It depends mostly on the evidence. If documents can be emailed or uploaded and everything is organized and printed, a case normally turns around in about 7 to 14 days. The analysis itself may take only four to six hours spread across several days.
What slows a handwriting investigation down?
Waiting on evidence — clients digging through boxes, attics, and bank vaults for samples — plus report writing, exhibit building, and attorney consultations. Some states also add steps: California requires a judge’s sign-off before a third party can handle an original document, while Texas does not.
How much lead time should you give a handwriting expert?
Ideally a three-month window to investigate, gather documents, and organize everything — and at least about three weeks of runway if you want to save money. Even after an opinion is formed, you are probably a month from trial.
What does a rush handwriting examination cost?
A true rush — “here are the documents, I’m in court tomorrow” — gets charged double across the industry, because staff drop everything and work overtime and weekends to deliver the opinion, lab reports, notes, and testimony prep.

Q34. Do Judges and Courts Actually Listen to Forensic Handwriting Experts?
Do Judges and Courts Actually Listen to Forensic Handwriting Experts?
Of course they do. And there’s a practical reason a judge would have an independent expert testify rather than rule on the handwriting personally: they don’t want their cases overturned.
Why a Judge Wants an Independent Voice
Think about a criminal case. If a judge is later found incompetent, every case that judge presided over can be thrown into question — and people can walk out of jail. You see it whenever corruption surfaces. One of the ways to keep a verdict from being overturned is to lean on expert testimony.
Can a judge tell whether a signature is real? Maybe. But if the judge gets it wrong while playing examiner, the verdict can be overturned. A third-party forensic document examiner provides independent validation — stating whether a signature or document is authentic. This isn’t unique to handwriting; it runs across many forensic disciplines. People like experts. Judges like experts. Juries like experts — especially independent ones.
Why Independent Expertise Matters
You can assume the lab tech doing the examination has no skin in the game. They don’t care whether the person goes to jail. They’re just trying to tell the truth. That’s how I approach my own work, and it’s how we’ve trained everyone at the International School of Forensic Documentation.
That commitment to the truth is what pulled me into this field. I was trained and qualified almost 30 years ago, and it’s been good work — helping people, finding the truth, bringing a little justice to folks who were about to lose their houses, their cars, even their inheritances.
I’ve saved a lot of people’s inheritance. In a Collin County estate dispute, for instance, if I hadn’t been in the room, a bad actor might have passed off a fraudulent last will and testament. That feels good. It’s good to make a living. It’s also good to make a difference.

Frequently Asked Questions
Do judges and courts actually listen to forensic handwriting experts?
Of course they do. There is a practical reason a judge has an independent expert testify rather than ruling on the handwriting personally: they do not want their cases overturned. Judges, juries, and attorneys all value experts — especially independent ones.
Why doesn’t the judge just decide whether a signature is real?
A judge might be able to tell, but if the judge gets it wrong while playing examiner, the verdict can be overturned. A third-party forensic document examiner provides independent validation that gives the ruling a defensible foundation.
Why does independence matter in expert testimony?
The examiner has no skin in the game — they do not care which side wins; they are trying to tell the truth. That neutrality is exactly what makes the testimony credible to judges and juries.
What difference can a forensic document examiner make in an estate dispute?
Without an expert in the room, a bad actor might pass off a fraudulent last will and testament. Independent examination has saved inheritances, houses, and cars by exposing forged documents before they changed the outcome.

Q33. How Accurate Is Forensic Handwritten Analysis?
How Accurate Is Forensic Handwriting Analysis?
It’s a great question, and the honest answer starts with one fact: this analysis is allowed in court. A judge will let a trained expert testify based on it. If it’s admitted as a viable forensic method, there’s clearly a scientific basis underneath.
You could just as easily ask, “How accurate are thumbprints?” or “How accurate is DNA testing?” They’re only as accurate as the person performing the test and the equipment used. Handwriting analysis is the same — the accuracy depends on the quality of the work and the jurisdiction you’re in.
Two Different Things People Call “Handwriting Analysis”
Here’s where it gets interesting. When some people say “handwriting analysis,” they mean the psychology of understanding people through their writing — useful for human resources and therapists. That’s a different discipline from determining who actually wrote a document.
I happen to be skilled at both, so I know the limits of the personality side. They come down to the practitioner’s skill level. I’m probably one of the more humble ones — I’ll tell you plainly what you can read and what you can’t. I wouldn’t claim to know whether someone’s cheating on you or is an evil person. I’m not making those broad leaps. Some character traits can be read, especially in people who learned cursive and wrote it all their lives. Less so for people under 35.
The Science Is About Procedure
Consider fingerprints. There are 13 points of comparison, and some states allow only 7 in court. So depending on the state, you might get a fully accepted result on seven points where another state wants 13 or more. Different states set different criteria for what counts as a forensic specialty.
But the science itself is accurate, because it’s all about procedure. There are dozens of procedures across forensic document work, handwriting, fingerprints, and shoe prints — and every one of them matters. You have to follow the procedure.
Put a court-qualified examiner on the question of whether a specific human being wrote a full handwritten note, and you’ll get an accurate opinion — as long as that person follows the procedures and has been trained to minimize bias. People are unconsciously biased by everything around them. Without procedural safeguards, an examiner can start hunting for evidence that confirms what the client wants to hear. That’s how bias creeps in.
Weighing the Evidence Correctly
Let me give you an analogy. In my truck there’s a steering wheel, a bottle of kombucha, and a phone. It has four wheels. It’s a truck. But if you weigh one detail too heavily — “there’s a steering wheel, so it’s a car” — you’ll be wrong. You focused on one thing.
Handwriting works the same way. You have to take in the whole picture. If an examiner spots a small difference in a G or a Y and announces “that’s a forgery,” they’ve weighed the evidence improperly. That’s where human error enters — not in the science, but in how someone weighs it.
Normally my peers reach my conclusion when we look at the same evidence, the same quantity, the same quality. That doesn’t mean every peer is ethical. If you’re hiring an examiner for a Tarrant County matter, ask about their training, their methodology, and whether they follow established procedures to minimize bias. The answers will tell you a lot.
So yes — forensic handwriting analysis is highly accurate when performed correctly. Those last three words carry the weight. Look for someone court-qualified, procedure-driven, and honest about the limits of the analysis. That’s how you get an opinion you can actually rely on.

Frequently Asked Questions
How accurate is forensic handwriting analysis?
Highly accurate when performed correctly. It is admitted in court as a viable forensic method, and like thumbprints or DNA testing, its accuracy depends on the person performing the test, the procedures followed, and the jurisdiction’s standards.
Is handwriting identification the same as handwriting personality analysis?
No. Determining who wrote a document is a separate discipline from the psychology of reading character through writing. The forensic side is what courts rely on to identify the writer of a questioned document.
How do procedures keep handwriting analysis scientific?
The science is about procedure — dozens of established procedures across document work — and every one matters. A trained examiner follows them to minimize unconscious bias; without safeguards, an examiner can start hunting for evidence that confirms what the client wants to hear.
What should you ask before hiring a handwriting examiner?
Ask about their training, their methodology, and whether they follow established procedures to minimize bias. Look for someone court-qualified, procedure-driven, and honest about the limits of the analysis.

Q32. The Craziest Cases I’ve Worked as a Forensic Handwriting Expert
The Craziest Cases I’ve Worked as a Forensic Handwriting Expert
Three decades in this field will hand you everything — contested wills, multi-million dollar fraud, the quiet civil disputes nobody televises. But two cases have always stood apart. One put me across a table from a double homicide suspect in a Los Angeles jail. The other swept me into a national media storm around one of the most famous unsolved cases in American history.
Case #1: Across the Table From a Double Homicide Suspect
This was one of my first major criminal cases, about two decades ago. I was working with the District Attorney, and I had to go down to the Los Angeles jail to collect handwriting standards from a man accused of a double homicide.
What made it forensically unusual was the evidence itself — graffiti on the tarp covering the bodies. Investigators wanted to know whether that graffiti could be tied to the suspect. The allegation was that after the killings, he “tagged” the tarp with his gang sign as a warning to rival gangs.
Here’s why that matters forensically. Gang tagging isn’t casual handwriting. In that world, tagging is identity and creative expression. Many gang members develop a distinctive script style that differs from their everyday writing — sometimes on purpose — and that’s an important nuance in any comparison.
What surprised me most was the man himself. People picture jailhouse interactions as hostile. That day, the suspect was cordial and cooperative. He wrote what I asked. And his natural handwriting — separate from the stylized tagging — was some of the most precise, looped, visually striking writing I’ve ever seen.
The tarp graffiti never made it into evidence. Even though I observed similarities, that “tarp testimony” wasn’t ultimately used. The testimony I gave in court related to a letter he wrote while in prison.
People ask whether this work is dangerous. Here’s what I learned from those familiar with gang culture: threats land far more often on judges and attorneys than on expert witnesses — especially when the expert is seen as doing a job, not picking a side.
Case #2: The JonBenét Ramsey Media Whirlwind
The second “craziest” one had nothing to do with sitting across from a suspect. It was about being pulled into the media machine.
When authorities announced they believed they’d identified JonBenét Ramsey’s killer and arrested a suspect in Thailand — John Mark Karr — I ended up doing a rapid run of radio and TV appearances. It turned into a three- to four-day media sprint, including a sit-down with the late Larry King on CNN to discuss the case from a handwriting and document-analysis angle.
One clarification matters here. I was not involved in the original JonBenét Ramsey case. My mentor, Phyllis Mattingly, served as the official police-hired handwriting expert in Colorado. What I knew of that case came through her involvement and the broader forensic discussion around it.
High-profile cases are “interesting” in a different way. The science can become secondary to headlines, speculation, and public pressure.
The Reality Behind Most Forensic Cases
People love the dramatic criminal stories. But the truth is, most documented cases are civil disputes. A lot of them are about money — business conflicts, estate fights, contracts, people suing each other. The kind of work that fills a Tarrant or Dallas County docket far more than a homicide trial does.
They’re real and they’re important, but they wouldn’t always make great TV. That steady work is what keeps the lights on. It’s also why having trained, court-qualified handwriting experts available across the country — and right here in North Texas — matters as much as it does.

Frequently Asked Questions
What was the craziest criminal case a handwriting expert worked?
A double homicide case in Los Angeles about two decades ago, working with the District Attorney. The examiner collected handwriting standards from the suspect in jail because investigators wanted to tie graffiti tagged on the tarp covering the bodies to the suspect’s gang sign.
Why is gang graffiti difficult to compare to normal handwriting?
Gang tagging is not casual handwriting — it is identity and creative expression. Many gang members develop a distinctive script style that differs from their everyday writing, sometimes on purpose, which is an important nuance in any comparison.
Was Bart Baggett involved in the JonBenét Ramsey case?
Not in the original case. His mentor, Phyllis Mattingly, was the official police-hired handwriting expert in Colorado. When suspect John Mark Karr was arrested, Baggett did a three- to four-day media sprint — including CNN’s Larry King — discussing the handwriting and document-analysis angle.
Are most forensic handwriting cases criminal?
No. Most documented cases are civil disputes about money — business conflicts, estate fights, contracts. That steady civil work fills court dockets far more than homicide trials do.

Q31. Can Two People Have Identical Handwriting?
Can Two People Have Identical Handwriting?
It’s a great question. And it’s really the foundation of why forensic handwriting analysis is treated as a science — one that can tell one human being apart from another.
That’s why I get to go to court. Our experts testify, and the judge says, in effect, “Okay, that’s science. There must be something to it.”
Nobody Writes the Same Way Twice
Start with something simple. You can’t sign your own name twice without at least one small variation. On top of that, no two people write exactly alike. The neural signals that travel from the brain to the hand create subtle distinctions from one person to the next.
From the research I’ve read, twins sometimes write very similarly. Mothers and daughters can share handwriting traits too — though not as strongly as fathers and sons. I suspect that’s more nurture than nature. Grow up in the same home, eat the same food, share a language and culture, develop similar personalities, and your handwriting may reflect that.
Why Twins Don’t Settle It
But that pattern doesn’t always hold — especially with twins separated at birth, who can have profoundly different personalities. Parents will tell you their twins are nothing alike: “Sam’s been introverted since the day he was born. His sister has needed attention since day one.” Twins don’t always share temperament.
I bring up personality on purpose. Handwriting reflects neurological activity — temperament and personality — as well as physiology, like the neural pathways themselves. That resulting difference is exactly what a forensic handwriting expert uses to tell one writer from another.
Where It Gets Harder — and Why You Still Need a Professional
If you do this work and a mother-daughter pair or a set of twins lands on your desk, expect a tougher comparison. They can share real qualities — more so if a mother and daughter are close in age and came up through the same Collin County schools, the same city, the same state. Even then, subtle neurological differences remain.
Those differences show up as ink spots, hesitations, and tick marks in the writing. That’s why this calls for a trained forensic document examiner rather than a casual eye.

Do twins or family members write alike?
Twins sometimes write very similarly, and mothers and daughters can share handwriting traits — likely more nurture than nature. But the pattern does not always hold, especially with twins separated at birth who develop profoundly different personalities.
Why does handwriting differ between people?
Handwriting reflects neurological activity — temperament and personality — as well as physiology like the neural pathways themselves. That resulting difference is exactly what a forensic handwriting expert uses to tell one writer from another.
How do experts distinguish similar family handwriting?
Family pairs make for tougher comparisons, but subtle neurological differences remain. They show up as ink spots, hesitations, and tick marks in the writing — which is why it calls for a trained forensic document examiner rather than a casual eye.
