Can a Forensic Expert Still Identify a Forgery If a Signature Changes Over Time

Los Angeles Forensic Handwriting Expert: Can Forgery Be Identified If a Signature Changes?

Can a Los Angeles Forensic Expert Identify a Forgery If a Signature Changes Over Time?

Yes. Signature changes over time are completely normal—and they are expected in professional forensic handwriting analysis.

This question comes up frequently in Los Angeles legal cases, including probate disputes, real estate litigation, contract challenges, and elder financial abuse matters:

  • “What if my signature looks different now than it did years ago?”
  • “Can an old signature still be compared accurately today?”

The short answer is simple: this is exactly what forensic document examiners are trained to do.

Do Signatures and Handwriting Change Over Time?

Yes. Handwriting and signatures can evolve gradually throughout a person’s life. Common reasons include:

  • Age and physical development
  • Name changes due to marriage or divorce
  • Career or writing habit changes
  • Major life events or psychological stress
  • Medical or neurological conditions

For example, handwriting often changes significantly between adolescence and early adulthood as fine motor control develops. Later in life, changes tend to be more subtle.

Importantly, these changes occur within a predictable range of natural variation.

How Los Angeles Forensic Handwriting Experts Evaluate Signature Changes

Professional forensic document examiners do not rely on a single signature or one isolated document.

Instead, they establish a baseline of authentic variation by examining:

  • Known genuine signatures spanning many years or decades
  • Writing samples before and after major life events
  • Multiple documents created under normal, real-world conditions

In many Los Angeles cases, experts analyze handwriting samples covering 20 to 30 years of a person’s writing history.

What Does Not Change in Genuine Handwriting

While surface appearance may evolve, certain identifying characteristics remain remarkably consistent:

  • Neuromuscular movement patterns
  • Stroke order and writing rhythm
  • Pen lifts, hesitations, and transitions
  • Line quality and pressure habits
  • Microscopic ink deposits and striations

These features are governed by physiology and biomechanics—not conscious control.

You cannot successfully fake another person’s neuromuscular handwriting system.

Why Original Documents Matter in Los Angeles Forgery Cases

The most reliable forensic conclusions come from examining original documents.

Using magnification and microscopy, forensic experts can identify:

  • Pen speed variations
  • Ink flow interruptions
  • Natural tremor versus simulated tremor
  • Microscopic pauses invisible in copies

Photocopies, scans, and faxed documents remove much of this critical forensic evidence.

Can Forgery Still Be Identified Despite Signature Changes?

Absolutely.

When sufficient genuine writing samples are available, a Los Angeles forensic handwriting expert can:

  • Differentiate natural variation from forgery
  • Identify disguised or slowly drawn signatures
  • Detect tracing, patching, and hesitation patterns
  • Provide a defensible, court-admissible expert opinion

If the findings support your legal position, the opinion may be presented through:

  • A written forensic report
  • A sworn declaration or affidavit
  • Live expert testimony in Los Angeles courts

Why Los Angeles Courts Rely on Forensic Handwriting Experts

Judges value independent experts who rely on science—not speculation.

A qualified forensic handwriting examiner provides:

  • Objective, unbiased analysis
  • Court-accepted forensic methodology
  • Clear explanations for judges, attorneys, and juries

This credibility often plays a decisive role in legal outcomes.

Final Takeaway

Signatures may change over time—but the underlying handwriting system does not.

That is why trained forensic document examiners can account for natural variation and still determine whether a signature is authentic or forged.

If you are involved in a Los Angeles legal dispute involving a questioned signature, do not guess. Obtain a professional forensic handwriting analysis.

Forensic Handwriting Expert in Los Angeles, California: What We Do, How We Testify, and Why It Matters

If you’ve ever stared at a signature and thought, “That looks… suspicious,” you’re in the right place. In Los Angeles and across California, disputed signatures show up in wills, contracts, real estate documents, business agreements, and the occasional family situation that could qualify as its own streaming series.

Forensic handwriting experts (also called forensic document examiners) play a crucial role in the legal system by examining handwriting and related evidence to help determine authenticity and verify signatures and documents. And yes—these experts can testify in court. In this article, we’ll break down what a forensic handwriting expert does, what courtroom testimony really involves, and how to choose the right expert for a Los Angeles, California case.

The Role of Forensic Expert Witnesses

Professional expert witnesses specialize in forensic processes such as DNA analysis, fingerprint examination, and handwriting analysis. Their job is to conduct thorough examinations, compile formal reports, and be prepared to testify in court when their conclusions are challenged.

Reality check: software can be helpful, but software can’t raise its right hand, swear an oath, and survive cross-examination. Courts need a qualified human expert who can explain the “how” and “why” behind the findings.

That “human element” matters, especially in Los Angeles courtrooms where testimony needs to be clear, credible, and understandable to judges and juries—people who did not sign up for a graduate seminar in forensic science.

Forensic Document Examination: What It Entails

A forensic document examination is a systematic, documented process. Depending on the assignment, an examiner may evaluate:

  • Signature structure, rhythm, and line quality
  • Natural variation vs. signs of simulation or tracing
  • Pen movement indicators (speed, pressure patterns, hesitations)
  • Document context and consistency across multiple known samples

The process culminates in a formal report outlining the findings and the analytical basis for the conclusions. When called to court in California, the examiner explains the methodology and offers an honest opinion—whether a signature appears genuine, simulated, or forged.

This is important because a report alone isn’t a live explanation. In court, the expert’s testimony helps the trier of fact understand what the evidence means in practical terms—beyond simply reading a conclusion on paper.

Why Objectivity Matters in Los Angeles and California Cases

A forensic handwriting expert is not supposed to be “Team Plaintiff” or “Team Defense.” The job is to be neutral—committed to facts, scientific integrity, and the truth. That means the opinion can sometimes disappoint a client if the evidence doesn’t support the story they hoped would be true.

Oddly enough, attorneys often respect this. An expert who is transparent and consistent is far more credible than an expert who only “finds what you paid them to find.” (Courts have a pretty good radar for that.)

How to Select a Qualified Forensic Handwriting Expert in Los Angeles

If you’re hiring a forensic handwriting expert for a Los Angeles, California matter, focus on courtroom readiness—not just marketing. Look for:

  • Demonstrated courtroom experience (deposition and trial testimony)
  • Clear reporting that explains reasoning, not just conclusions
  • Ability to teach (because juries aren’t mind readers)
  • Professional objectivity and consistency under questioning

Conversely, an “expert” with no courtroom experience may struggle to communicate complex forensic findings to a judge or jury— and in trial, communication is half the battle.

Bottom Line

Forensic handwriting experts do more than analyze signatures. They provide courtroom testimony that helps ensure decisions are made using evidence, not guesswork. In Los Angeles and throughout California, that can be the difference between a case that collapses under scrutiny and a case that stands up under cross-examination.

How do I Authenticate a Signature?

Admin2020 Leave a comment

Authenticating a signature is the process of determining if a signature is real or fake. This is often important when dealing with legal documents, such as a will or a title. 

One way to authenticate a signature is by hiring a forensic handwriting expert. These experts can examine the signature and compare it to known samples of the person’s handwriting in order to determine its authenticity. 

They may also test the paper and ink used to create the signature in order to further verify its authenticity. It is common for courts to recommend hiring a forensic handwriting expert in cases where the authenticity of a signature or document is in question. This is especially true when there is a lot of money at stake, such as in the case of a large estate being fought over. Hiring a handwriting expert can be a costly process, but it can be well worth it in order to determine the authenticity of a signature or document.

One expert in this field is Bart Baggett, a forensic document examiner who has extensive experience in handwriting analysis and signature authentication. Baggett has written several books on the topic and offers training and consulting services to individuals and organizations. You can reach him at www.handwritingexpertusa.com

What do you do if you think someone Forged Your Parents Last Will and Testament?

Admin2020 Leave a comment

The death of your parents is a difficult time. Dealing with the probate court and a possible forged will is also a burden many children across the globe must deal with. This short article tells you how.

If you’re reading this, you’re probably in the unfortunate situation of having one of your parents pass away, and you’re stuck dealing with the last will and testament.

If the signature on the Last Will and Testament or those Trust documents doesn’t look like an authentic signature, this article is for you.

My name is Bart Baggett and my company (Handwriting Experts Inc) http://handwritingexpertusa.com  deals with probate cases every day.  We deal with signatures, trusts, deeds, and Will.   

Oftentimes, it is in the case where someone has passed away and the entire estate rest in the hands of the probate court judge.  Your parent’s house, cards, jewelry, and the entire estate can be handed to the idiot step-child if the judge thinks that is the last wishes of your parents. 

It’s our burden to figure out our parents’ stuff. And unfortunately, it’s really, really common for brothers, sisters, uncles, and caretakers to forge wills and take everything— and I mean everything!

So, you’re not alone in this situation. And I know it’s confusing. If you’re not an attorney, then this will be very helpful for you. I’ll walk you through how we work with probate cases and how a court-qualified handwriting expert can help you during the process.

At Handwriting Experts Inc., we are document examiners. We take handwriting samples of the decedent—your mom or your dad—and we determine if indeed the will for this person has been forged.

Here are the steps we follow to determine if a Last Will and Testament has been forged.

  1. Is there a document with the original, or “wet”, signature?

Often times in a probate case, there’s an actual wet, or original, signature sitting at the courthouse with a will. But that’s not always true. If it’s possible to get access to that will, I’ll personally come with my microscope. Or, one of my people will come into the courthouse, take photographs of it, and make sure that it’s a wet signature.

This is a blue pen on paper. See how the ink flows onto the paper. This is magnified 20x through a stereo microscope.
This is not wet ink. This the output from a color print. Can you see the red and yellow dots?
  1. Compare the signature on the will with other samples of the decedent’s signature.

Next, we’ll compare those signatures to other samples of your parent’s handwriting—their passport, visa, checkbook, birth certificates, wedding certificates, etc. We’ll look for their known handwriting. Your that’s your job is to find their known handwriting. And then, we will compare it.

  1. Determine if the signature on the will is authentic or if it has been forged.

We’re handwriting experts. I’ve been doing this for 30 years; I’ll know for sure whether that signature is forged. Even if the parent was really sick, had Alzheimer’s or Parkinson’s, we can take all that into consideration. And it’s impossible to slip a forgery past trained eyes.

So, once I or my team does that job, we decide if a forgery happened. If it did, we’ll write a declaration. And if you need, we’ll come to court and testify on your behalf. 

If this is a service that you need, the pricing is on our website.

Whether you deal with me or any of our experts, or any expert in the country for that matter, the process is pretty much the same. In order to prove a forgery in court, you’re going to have to hire a forensic handwriting expert, and they’re going to have to be court qualified. They’re going to have to testify. Otherwise, it’s just your word against his or hers.

And that’s the process of how you handle the determination of a forgery of a will and testament in court.

If you need our help, please reach out. Our main website is handwritingexperts.com. You can hire any of our professional experts on the website. If you want to hire me directly, go to handwritingexpertusa.com.

We have offices around the country, and we’ll travel to you to help you through this difficult time.  While we know the circumstances for needing our services are not the best, at least you can rest knowing the wishes of your loved one have been fulfilled.
