Do You Need an Original, or Can a Document Examiner Work From a Photocopy?
Attorneys hire a forensic document examiner to tell a court whether something is or isn’t a forgery. The evidence might be a will, a codicil, a title — any document that helps the court get to the truth of an agreement. This has been happening for centuries, and it happens all the time.
And one worry comes up again and again: “I don’t have an original. I’m going to lose this case.”
That’s not true.
Even with a Last Will and Testament — where state law usually wants a wet signature and two witnesses — a court will sometimes accept a copy as valid evidence.
How Evidence Has Changed Over the Decades
I’ve been doing this for about thirty years, and the documents that land in front of a judge have shifted. When the first textbooks on forensic document examination were written, originals were the only kind of evidence there was. In the 1980s, faxes started showing up as evidence. Photocopies have been used since the copy machine was invented.
Fax machines have mostly vanished, and fax copies along with them — replaced by PDFs, email attachments, and scans of every quality you can imagine. There are high-resolution scanners and low-resolution scanners. What a lot of clients don’t realize is that deeds and titles recorded at the courthouse — say, a property record in a Dallas County file — are often scanned at very low resolution. And sometimes that low-res scan is the only copy that still exists.
The Best Evidence Rule
The general rule across all fifty states is the Best Evidence Rule. It says the court will accept the highest-quality version available — which means even a photocopy can be admitted if it’s the best version of the document there is. An examiner’s opinion built on that copy can still carry real weight.
So will a forensic opinion based on a photocopy be accepted? Yes. An inconclusive opinion is still a valid opinion. A finding of “more likely than not authentic” carries weight in court. And in some cases an examiner can reach an absolute conclusion without an original at all — though originals are always preferred. If you have the originals, of the known signatures or the questioned one, we want to see them. We always want the best evidence on the table.
Honestly, fifty to sixty percent of our cases end up producing a letter, and maybe going to court, based on some form of photocopy — because the original is simply lost. I once had a copy of a marriage certificate from Mexico, signed in 1956. The original didn’t exist anymore. That’s a seventy-year-old document, and we had to make the best decision possible given what we had.
What to Do Before You Hire an Expert
When you call your local office, tell the examiner exactly what you’re holding. Sometimes the resolution is so poor the copy is almost unreadable. If you can’t identify the ink, can’t make out the letters, everything’s faded — you probably can’t move forward. That’s a conversation worth having before you invest $5,000 to retain an examiner and get a letter.
So the answer is yes. You can bring a photocopy. Yes, the judge will allow it. You can win without an original. It’s simply always better to have higher-quality evidence — and more of it.

Frequently Asked Questions
Do you need an original document to prove forgery?
No. Even with a Last Will and Testament, where state law usually wants a wet signature and two witnesses, a court will sometimes accept a copy as valid evidence. You can bring a photocopy, the judge will allow it, and you can win without an original.
What is the Best Evidence Rule?
The general rule across all fifty states says the court will accept the highest-quality version of a document available — which means even a photocopy can be admitted if it is the best version that exists. An examiner’s opinion built on that copy can still carry real weight.
How often do document examiners work from photocopies?
Roughly fifty to sixty percent of cases end up producing a letter, and possibly going to court, based on some form of photocopy because the original is simply lost — including documents as old as a 1956 marriage certificate from Mexico.
When is a photocopy too poor to examine?
If the resolution is so low the copy is almost unreadable — you cannot identify the ink or make out the letters — you probably cannot move forward. Discuss exactly what you are holding with the examiner before you invest in a retainer and formal letter.
