People often ask a simple question that actually has a very technical answer: Can a handwriting expert really tell if a signature is forged?
Yes… and we can tell who wrote a ransom note, too.

Handwriting Evidence Has Solved Crimes for Over a Century… and we still use it in courtrooms in Texas.

My name is Bart Baggett. I’m a forensic document examiner, and for decades my work has involved examining handwriting and signatures in legal disputes. In cases across the country — including matters involving wills, contracts, and financial documents — trained experts can determine whether handwriting is authentic or forged.

This type of analysis isn’t new. Courts have relied on handwriting examination for well over a century.

Handwriting Evidence Has Solved Crimes for Over a Century

One well-known example comes from the Lindbergh baby kidnapping case in the 1930s. A ransom note demanding $50,000 was left in the child’s nursery. Investigators later compared the handwriting on that note with banking documents connected to the ransom money. I hosted an indepth video here about it.

Handwriting analysis helped investigators connect the suspect to the crime.

That case happened in 1935. Even then, forensic handwriting comparison was already a recognized investigative and courtroom tool.

Is Handwriting Really Unique to Each Person?
Yes, it is.

Handwriting develops through years of muscle memory, habit, and small unconscious movements. Even people who learned the same cursive style in school end up writing differently over time.

Those small variations are what forensic document examiners study.

Much like fingerprints, handwriting carries patterns that are highly individual. When enough quality writing samples are available, those patterns can be compared with surprising precision.

Where Forgery Questions Usually Appear in Legal Cases

In my experience, the most common disputes involving handwriting are not celebrity autographs or sports memorabilia.

They are legal documents.

Wills. Contracts. Estate documents. Business agreements.

In the Dallas–Fort Worth, Texas area, for example, disputes often arise around handwritten or “holographic” wills. When an entire page of handwriting is questioned, the examination becomes much more detailed than simply comparing signatures.

Forging a full page of natural handwriting convincingly is extremely difficult. Even skilled imitators tend to leave clues behind.

Frequently Asked Questions

How did handwriting evidence help solve the Lindbergh baby case?

A ransom note demanding $50,000 was left in the child’s nursery in the 1930s. Investigators later compared the handwriting on that note with banking documents connected to the ransom money, helping connect the suspect to the crime.

Is handwriting really unique to each person?

Yes. Handwriting develops through years of muscle memory, habit, and small unconscious movements — even people who learned the same cursive style end up writing differently. Like fingerprints, those patterns are highly individual and comparable with surprising precision.

How long have courts relied on handwriting examination?

Well over a century. The Lindbergh case happened in 1935, and even then forensic handwriting comparison was already a recognized investigative and courtroom tool — one still used in Texas courtrooms today.

What legal documents most often involve forgery questions?

Wills, contracts, estate documents, and business agreements. In the Dallas–Fort Worth area, disputes often arise around handwritten “holographic” wills — and forging a full page of natural handwriting convincingly is extremely difficult.
