Signature Verification Forensic Test For Investigation of Frauds & Forgeries

What is A Signature Verification Test?

The signature of a person is unique to him/her, just like a fingerprint and DNA. Technically, the signature is a part of one’s unique handwriting. A signature verification forensic test is used to find out if the signature on a document is faked (forged) by someone. The signature verification itself is an extension of the Handwriting Examination tests and is helpful in many cases, requiring authentication of legal documents, bank cheques, and the likes.

What Forms the Basis for a Signature Verification Forensic Test?

Every person writes differently, so does he or she signs. There are patterns, applied pressure, strokes, curves, etc., which are unique to every individual’s handwriting and signature. There would always be some natural variation associated with the handwriting and signature. Howsoever masterfully done, a faked signature can be easily detected by a forensic expert.

A signature is a symbolic representation of consent to agree to the document signed. By signing a document, agreement, etc., we agree to the terms and are legally bound to them. Hence, it may bring forth unwelcomed situations, which can often lead to litigations and other legal consequences. Hence, it is important to get a signature verification test, even in case of the slightest doubt.

  • Transmitted light

How Does a Signature Verification Forensic Test Determine the Variations?

Forgery is a crime. The signature may be valid, but the manner in which it has been acquired may be fraudulent. This can be said as a fraud, not forgery. At DNA Forensics Laboratory Pvt. Ltd., we use the latest and most sophisticated methods of signature verification for accurate results.

A signature has most of the features of one’s handwriting. It is an extension of handwriting. It is sometimes personalized and is not even legible/readable to others. It can be said to have formations and not alphabets. A person may try and be successful in copying someone’s signature, but there will always be variations. Though these variations may not be visible to inexperienced eyes, our signature verification forensic experts can easily and accurately detect them.

The forger may start or stop bluntly or with undue emphasis. These small details may not be visible to a layman. Normally, a signature starts and stops dynamically. This leaves a tapered look at the beginning and end. The hesitation in the mind of the writer can easily be detected. The pen moves slowly, and in some cases, microscopic tremors can be detected.

In the case of a fraud signature, the accused may even try to rewrite and fix up some mistakes. Our experts can also differentiate between the signatures of an aged writer since they also show similar traits. This is called auto forgery. Auto forgery cases can also be solved where the person denies his own signature.
