In legal disputes, one simple change on a document, like erasing a number or changing a
date can make a big difference. Whether it’s a will, a contract, or a signed check, even small
alterations can lead to major consequences. At America’s Handwriting Expert, we use
forensic document analysis to uncover signs of tampering and help you know if a
document is real, changed, or fake.

When you’re dealing with questionable documents, it’s important to work with trained
professionals. Our team uses scientific tools and court-approved methods to find changes
like erasures, additions, and overwriting. Learn more at America's Handwriting Expert.
Why Document Changes Matter
In many legal cases, the outcome depends on a single piece of paper. If that paper has been
changed in any way, it could lead to fraud or unfair results. Some common examples
include:

● Changing the amount on a check
● Adding or removing information from a contract
● Altering the date on a legal agreement
● Modifying details in a will or trust

These changes are often hard to see with the naked eye, which is why forensic document
experts are so important. We look closely at the document to spot even the smallest signs of
tampering.
The Three Main Types of Alterations
1. Erasures
This is when someone removes writing from a document. It can be done using an eraser,
sandpaper, or even computer software. Even if the surface looks clean, the paper fibers may
be damaged, and there may still be tiny ink traces left behind.
Using tools like special lights and magnification, we can find evidence of erasures, even if
they are invisible to the naked eye.
2. Additions
This happens when someone adds something new to a document that wasn’t there
originally. For example, an extra zero might be added to increase a dollar amount, or a new
sentence might be added to a contract.
We use ink testing and handwriting analysis to see if these new parts match the rest of the
document. Often, we find differences in pressure, style, or ink type that prove something was
added later.
3. Overwriting
Overwriting means changing existing writing by writing over it. This is often seen in altered
dates or amounts, where someone changes a "3" into an "8" or adjusts the year.
This type of alteration can leave signs like ink layering, uneven strokes, or pressure
changes. Our tools help reveal these details to show whether the writing has been changed.

How We Find Document Alterations
At America’s Handwriting Expert, we use a variety of methods to detect changes in
documents, including:
● Microscopes to examine paper and ink closely

● Infrared and ultraviolet lights to see hidden ink or erased text
● Video Spectral Comparators (VSC) to identify ink differences
● Electrostatic Detection Apparatus (ESDA) to find hidden writing impressions

These tools help us analyze the document without damaging it, which is important in legal
cases.

Questioned document examination (QDE) is the forensic science discipline pertaining to documents that are (or may be) in dispute in a court of law. The primary purpose of questioned/forensic document examination is to answer questions about a disputed document using a variety of scientific processes and methods. Many examinations involve a comparison of the questioned document, or components of the document, to a set of known standards. The most common type of examination involves handwriting wherein the examiner tries to address concerns about potential authorship.

A document examiner is often asked to determine if a questioned item originated from the same source as the known item(s), then present their opinion on the matter in court as an expert witness. Other common tasks include determining what has happened to a document, determining when a document was produced, or deciphering information on the document that has been obscured, obliterated or erased.

The discipline is known by many names including forensic document examination, document examination, diplomatics, handwriting examination, or sometimes handwriting analysis, although the latter term is not often used as it may be confused with graphology. Likewise a forensic document examiner is not to be confused with a graphologist, and vice versa.
