Types of Forgery in Forensic Document Examination

Forgery is one of the most common forms of document-related crime investigated in forensic science. In simple terms, forgery refers to creating, copying, or altering a document with the intention to deceive or commit fraud. Therefore, it is often associated with legal documents, financial transactions, contracts, and identification papers.

In forensic document examination, experts analyze handwriting, signatures, ink, and paper to determine whether a document is genuine or forged. As a result, understanding the different types of forgery is important for investigators, legal authorities, and forensic professionals.

Simple Forgery (Freehand Forgery)

First, simple forgery, also known as freehand forgery, occurs when a person attempts to reproduce someone else’s handwriting or signature from memory.

In this case, the forger does not look at the original writing while creating the forgery. Consequently, the forged writing often appears different from the genuine handwriting.

For example, the letter shapes, spacing, and proportions may vary significantly from the original. Therefore, this type of forgery is usually easier for forensic experts to detect.

Simulated Forgery

Secondly, simulated forgery happens when the forger carefully copies an original signature or handwriting while looking at it.

At first glance, the forged writing may look very similar to the genuine one. However, closer examination often reveals certain differences.

For instance, simulated forgeries usually show slow writing speed, hesitation marks, and unnatural pen movements. As a result, forensic document examiners can often identify these subtle signs of imitation.

Traced Forgery

Another common type of forgery is traced forgery. In this method, the original writing is traced using different techniques.

For example, the forger may use carbon paper, transparent surfaces, or light boxes to copy the original writing. Consequently, the traced writing often lacks natural variation.

Moreover, traced forgeries frequently show uniform line quality, tremors in strokes, or indentation marks on the paper. Because of these characteristics, forensic experts can detect traced documents using specialized tools.

Disguised Writing

In contrast to other types of forgery, disguised writing occurs when a person intentionally changes their own handwriting style.

In other words, the writer tries to hide their identity by altering their normal writing habits. For example, they may change the size of letters, writing slant, spacing, or writing speed.

However, it is extremely difficult for someone to completely hide their natural handwriting characteristics. Therefore, forensic document examiners can often identify disguised writing through detailed analysis.

Forged Signature (Signature Forgery)

Finally, forged signature is one of the most common forms of document fraud. In this situation, someone signs another person’s name without permission.

Typically, this type of forgery occurs in financial or legal documents such as cheques, contracts, or agreements.

Although a forged signature may appear similar to the genuine one, forensic experts often notice differences in pen pressure, stroke order, and writing rhythm. As a result, these clues help investigators identify fraudulent signatures.

Conclusion

In conclusion, forgery is a serious issue in document-related crimes. Overall, the main types of forgery include simple forgery, simulated forgery, traced forgery, disguised writing, and forged signatures.

Each type has unique characteristics, which forensic experts analyze using scientific methods. Ultimately, forensic document examination plays a crucial role in detecting fraudulent documents and supporting legal investigations.
