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.

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.

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.

What is the difference between a handwriting expert and a forensic document examiner?
“Forensic document examiner” is the technical term for the professional who checks a signature’s authenticity; the specialty is handwritten items. “Handwriting expert” usually refers to the same professional.

Q18. Can Someone Actually Fool a Handwriting Expert?
Can Someone Actually Fool a Handwriting Expert?
I’ve seen magicians make the Eiffel Tower disappear, so I imagine that with enough trickery, someone could fool a forensic expert. But I’ll tell you this: if you hire a court-qualified expert who’s gone to court 100 times and been at this for many years, it’s hard to fool them by simply presenting false evidence.
You can lie to your lawyer. You can lie to the judge, the officer, even your ex-wife. But when it comes to the evidence, the evidence generally doesn’t lie.
Speaking for the Documents
I remember a CSI episode where the coroner said, “It’s my job to speak for the dead.” I feel the same way. It’s our job as expert witnesses to speak for the documents—for the person who created this will and testament and everything in it. The question is always: how does the evidence narrate the truth?
So yes, a document examiner—or any expert witness—could be fooled, especially if handed only a selective slice of the evidence.

Only Part of the Map
Think of a military briefing where someone shows you only part of the map. “Attack this side over here. Look at the radar—there are no troops.” But in reality all the troops are on the other side; the map just doesn’t show them.
People have tried exactly that with us—handing over selected evidence and saying, “That’s all we have, we can’t find any more.” We’ve also had clients submit comparison samples that weren’t written by the subject at all—a brother’s handwriting, a neighbor’s—presented as the person’s own. That’s exactly why our protocol requires us to verify the provenance of every sample.

Why Protocol Exists
Within our protocol—and every expert witness works this way—you have to make a judgment call on whether a given piece of evidence belongs in the comparison. Every industry has a procedure and a basis of opinion. Over the past several decades, professional boards and peer-review bodies built these protocols specifically to keep experts from being misled, cutting corners, or reaching conclusions that can’t be independently verified.
That’s really the point of an expert witness who follows the forensic protocols. They want to be able to hand the case to another expert they’ve never met and say, “Take the same evidence. Run the test. See what you get.” That’s how it works with DNA. With fingerprints, hair analysis, a foot imprint. Just like the crime shows—it’s still a science, and there’s a protocol.
Who Actually Hires Us
Could someone fool an expert? Sure. I’m certainly not going to outline the methods here—I want to catch the people doing the fooling. I want to be able to tell my attorney clients, “Your client is lying. He absolutely submitted that false document,” and help the truth come out.
In practice, someone who forged a document rarely turns around and hires an expert to examine it. The math doesn’t work, and neither does the logic. What we get instead are attorneys—a Tarrant County lawyer weighing a case on contingency, for example—saying, “My client swears his wife signed this, and I’m not sure I believe him.” That’s why I have dozens of attorneys coming back year after year asking, “Please help me. I need to know the truth.”
Whether you’re an attorney vetting a client’s story or someone who suspects fraud, the first step is always the same: find out what the evidence actually says.

By handing over selected evidence — “that’s all we have” — or submitting comparison samples that were never written by the subject at all: a brother’s handwriting, a neighbor’s, presented as the person’s own. Protocol requires verifying the provenance of every sample.
What protects the analysis from being misled?
Forensic protocol. Professional boards and peer-review bodies built procedures over decades so another expert can take the same evidence, run the same test, and independently reach the same result — just like DNA or fingerprints.
Do forgers ever hire handwriting experts?
Rarely — the math and the logic don’t work. In practice it’s attorneys who call, saying “my client swears his wife signed this, and I’m not sure I believe him,” because they need to know the truth before trial.

Q12. What Happens When a Tenant Forges a Lease and Won’t Leave?
What Happens When a Tenant Forges a Lease and Won’t Leave?
If you own rental property, this may sound far-fetched—right up until it happens to you. You’re trying to raise the rent or move someone out. They refuse. Then one day they hand you a lease you never wrote, never signed, and never knew existed.
I’ve seen this play out many times over my years as a forensic document examiner. Large condominium complexes, restaurants, office buildings—a scammer simply shows up and says, “I belong here. This is my place. Look at my lease.”
A Case That Shows How Far It Can Go
A few years back I worked a case where the defendants produced a 10-page lease supposedly signed by their landlord’s deceased father. I was on the landlord’s side.
The signature was bad, but it wasn’t the only thing that was faked. Every page had been typed word-for-word from the original lease—and the scammers made typos along the way. Because they made those typos on every page, I was able to trace the document back to the original draft on their own computer, where they’d manufactured the whole thing.
The tenant lost badly and likely had to cover all the experts and attorneys. That was a multi-million dollar case. If you own a triplex in Tarrant County, you probably can’t fund a fight like that. But you can almost certainly afford the help of a forensic document examiner to prove the lease is fraudulent.

What If I’ve Been Scammed but Have Limited Resources?
This comes up often with clients who rent out or take over a small property. The tenant says, “We have a lease,” or “We’re in rent control, and here’s the one you signed—or your dad signed, even though he’s passed.” The owner panics, because they can’t find any matching copies of the old leases.
That’s where the examiner comes in. We look for a pattern. If your father had been renting properties for 20 years, he probably used a standard lease. If the document that suddenly appears doesn’t match the formatting, font, notary, or timing of the prior set, the examiner can tell. We investigate where, if anywhere, the lease deviates.
So if you’re a Dallas-area landlord facing a manufactured lease, you can win in court, get the tenant evicted, and turn the property around. You’ll likely want a real estate attorney and a forensic document examiner. The tenants will probably lie—say you signed it, a friend signed it, a friend was the notary.

In that case, another angle is the paper itself—specifically its age. And if you’re lucky enough to get access to the renter’s computer, you may find the file where they built it. Almost 20 years ago I had a case where someone downloaded a last-will-and-testament template, and the copyright on it was dated two years after the person had died. Pretty hard to sign a will when you’re already gone.
The good news is that manufactured leases almost always leave a trail. Following that trail is exactly what a forensic document examiner is trained to do. We’ve handled lease problems in San Francisco, Tennessee, Dallas, Los Angeles, and through our experts around the country. It is not uncommon.
How Do I Know Whether the Fight Is Worth It?
The question to ask is simple: is it worth the fight? Is it worth evicting this person, recovering the property, and turning it over—or is it better to let them stay?
Usually, a tenant forging a lease is already far behind. They’re leaning on rent control and they want to stay forever. In most cases, pursuing an investigation is the right financial decision, especially when the alternative is letting a fraudulent tenant stay indefinitely.
Some States Are More Landlord-Friendly Than Others
If you own property in California, you carry a second layer of difficulty. The state strongly favors tenants. I’ve seen a case where someone lived in a property for two and a half years without paying a dime because the state blocked the eviction. That’s why many investors prefer Texas or Tennessee, where the laws are more balanced.
If someone doesn’t pay rent, they’re effectively stealing from your business and your family. Most landlords in this country are mom-and-pop operations—one to three units, their nest egg, their retirement. Four months of unpaid rent is $12,000 gone. That’s not a victimless situation.
If you sign a contract to pay $3,000 a month, you pay it. That’s the rule. And if you don’t, you’re taking money out of someone else’s pocket.
What to Do If You Suspect a Forged Lease
If you believe someone forged a lease to stay under rent control, hire a forensic document examiner. Hire an attorney. Then move promptly through the proper legal channels—notice, eviction posting, and getting the case before a judge as fast as you can.
Once you reach an evidentiary hearing, the tenant usually has to move out or give up. If it’s proven they manufactured false evidence in a court case, they can be prosecuted criminally. Police don’t love civil or “he said, she said” matters, but the threat of civil or criminal action for filing a false document and lying under oath is serious. That’s worth keeping in mind during negotiations.
If you’re a landlord, a real estate investor, or just someone who’s been handed a lease that doesn’t add up, we can help. We handle the forensic side—analyzing the evidence—and we can point you to good attorneys who handle these cases across the country.

Frequently Asked Questions
What happens when a tenant forges a lease and won’t leave?
A landlord can win in court, get the tenant evicted, and turn the property around — typically with a real estate attorney and a forensic document examiner proving the lease is fraudulent. Once an evidentiary hearing arrives, the tenant usually has to move out or give up.
How do examiners expose a manufactured lease?
By looking for a pattern. If the suddenly-produced lease doesn’t match the formatting, font, notary, or timing of the owner’s standard leases, the examiner can tell. Paper age and even the tenant’s computer files can complete the trail — manufactured leases almost always leave one.
Can a tenant be prosecuted for a fake lease?
If it’s proven they manufactured false evidence in a court case, they can be prosecuted criminally. The threat of civil or criminal action for filing a false document and lying under oath is serious — worth remembering during negotiations.
Is fighting a forged lease worth the cost?
Usually yes. A tenant forging a lease is typically far behind on rent and hoping to stay indefinitely; four months of unpaid rent alone is thousands gone. Pursuing an investigation is in most cases the right financial decision.

Q11. My Landlord Forged the Lease. What Are My Options?
My Landlord Forged the Lease. What Are My Options?
If you’re a tenant facing eviction over a lease you never signed, you’re in one of the most frustrating spots in civil law. And, unfortunately, one where your options are narrower than most people expect.
Eviction cases run through a special civil court — usually just called Eviction Court. It moves fast and it’s highly procedural. If you don’t know the process, you can lose before you ever get to tell your story.
I’ve seen how this plays out. In Van Nuys, there are lawyers who represent only tenants and others who represent only landlords. It’s a fight, and it’s a very procedural one. If you think being wronged means you’ll call the police and they’ll arrest your manager for forging a document — that’s probably not true.
When Fighting Back Isn’t Worth the Cost
Here’s the advice I gave a man who recently called our office. He said, “My landlord raised the rent by $100. I never signed a new lease.”
I told him the math. “You could spend $7,000 to $10,000 on a good attorney, and another $5,000 to $8,000 on a forensic handwriting expert. You probably won’t get the police to prosecute anyone, because no one can easily prove who forged the lease. If money is your main concern, your best bet may be to negotiate or move out.”

That wasn’t what he wanted to hear. He wanted justice. And I get it. When someone forges something, your mind goes straight to, “We can put this guy in jail — he created a false document.”
But that only matters if the police actually look into it, or you end up in front of a judge who has to decide what’s real. Is it wrong to forge a lease? Of course. It’s crazy. But as a tenant, you don’t have many rights in that regard.
When the Stakes Are High Enough to Fight
Commercial real estate is a totally different ballgame. I’ve seen a number of cases recently with big, famous Los Angeles restaurants — legacy places, 40 to 50 years old — where the leases are now in controversy because the original owner passed away. I can’t use names, but you’d know them. They serve the most beautiful steak ever.

When the owner dies, people start saying, “I want to renegotiate this.” And the other side says, “No — your dad and I had a deal.” Whatever is in writing is what the judge will enforce. The remaining parties either renegotiate or fight over whether a signature was coerced.
If you’re one of those people with a big lease problem — real estate or a restaurant running $10,000 to $30,000 a month — you have clear steps to take. The same is true for a high-value commercial lease in Tarrant or Dallas County.
What to Do Next
First, make sure the signature you think is forged actually is forged — because it might not be. You need a forensic document examiner to take the case, determine whether the document is forged, and then you go to your attorney and say, “We think we have a false document, and now we can fight this in court.”

And if you hire an examiner with real integrity and they come back with, “I don’t think this was forged,” you can still fight on other grounds. It’s worth knowing that verbal agreements are legally enforceable in most states, which may give you another way to contest the written lease even when the forgery is hard to prove.
But the real question is whether it’s worth fighting. If you’re a tenant who can move out for a hundred bucks, you probably won’t want the expense. If it’s a multi-million-dollar, 20-year contract, you have to fight — and you need good attorneys who understand civil procedure, expert-witness procedure, and document handling. Plenty of civil attorneys specialize in documents and business transactions, and they’re the ones who bring in a forensic document examiner to figure out whether the lease was poached.

Frequently Asked Questions
What are my options if my landlord forged the lease?
First, confirm the signature actually is forged — a forensic document examiner determines that. Then your attorney can fight it in court. Eviction court moves fast and is highly procedural, so knowing the process matters as much as being right.
Will the police prosecute a forged lease?
Probably not — no one can easily prove who forged the lease, and what feels criminal is almost always handled as a civil matter. That only changes if a judge is confronted with proven false evidence.
When is fighting a forged lease not worth it?
When the money at stake is small. A good attorney can run $7,000–$10,000 and an expert $5,000–$8,000 — so over a $100 rent increase, negotiating or moving out may be the better financial call.
When should a tenant absolutely fight?
High-stakes leases — commercial real estate or a multi-million-dollar, 20-year contract. And if the forgery is hard to prove, remember verbal agreements are legally enforceable in most states, which can offer another way to contest the written lease.

Q10. What’s the First Thing I Should Do if I Think a Document Has Been Altered or Forged?
What’s the First Thing I Should Do if I Think a Document Has Been Altered or Forged?
You call a forensic expert. Let me explain why that’s the first move.
Say someone is suing you over a contract you never signed. Or you’ve got a car loan, and you say, “I didn’t sign this,” and the bank says, “Yes, you did.” Now you have a legal problem.
You can call your attorney, and they’ll tell you the same thing — go find a court-qualified forensic handwriting expert to analyze the document.
What an Altered Document Looks Like
The same goes for an altered document. Say your uncle passes away, and there’s a five-page will. His signature is on the last page, but pages three and four are on different sheets, in different fonts. It looks off.
The last page may be original, but the middle pages were swapped. Suddenly all the money goes to his dog instead of you.

Alterations take a lot of forms. Whiteout. A different type of paper. Yes, someone really will reach for whiteout. It could be photoshopped. It could be cut and pasted — a lot of cases now are assembled in Photoshop or Microsoft Word and passed off as genuine signed contracts. Contracts, deeds, car titles, prenuptial agreements, wills and testaments, you name it.
If there’s a document and there’s money on the line, some unscrupulous person will slip something in and say, “Look, you signed this.”
I See This Constantly With Landlords
Some renters seem to treat the landlord as the enemy. “You can’t evict me!” the renter says. “What are you talking about?” the landlord answers. “It says you have 25 years at $400 a month. Why would I sign that?”
“It’s got your signature.” “Well… it does have my signature.” That’s exactly the kind of dispute that lands in a Dallas County or Collin County courtroom.

So, What Do You Do First?
The first step, if you think you’re a victim of forgery or a document has been altered, is to find a court-qualified forensic document examiner in your area. Their only job is to analyze the document and tell you the truth.
Has this been altered? Has it been forged? The truth arrives as a written forensic report. That report can become a declaration. The declaration can become live testimony — in person or even over Zoom. That’s how you solve the problem and get yourself out of trouble.
And if you’re lucky, the judge makes the other side pay for your legal team and your expert witnesses. So — what’s the first thing you should do? Hire a professional.

What’s the first thing to do if you think a document was forged?
Call a court-qualified forensic document examiner. Even your attorney will tell you the same thing — their only job is to analyze the document and tell you the truth about whether it has been altered or forged.
What does an altered document look like?
