How many exemplars are sufficient in signature verification?

Signature verification is a forensic analysis method, often used to determine the authenticity of signatures in legal documents, contracts, and other important paperwork. This method involves comparing the features of a disputed signature with known samples of the individual’s signature.

Experts recommend comparing a minimum of 20 to 30 known signature samples to ensure accuracy in the verification process. This helps to minimize the risk of false positive or false negative interpretations, ensuring a reliable outcome.

Clients often inquire about the possibility of verifying signatures with fewer than 20 samples or using photocopied exemplars. However, it is advised against doing so to maintain the integrity of the analysis and avoid potential inaccuracies.

For the most accurate results, it is essential to provide original documents with high-quality signature samples for the verification process. This ensures a thorough examination of the handwriting features and increases the reliability of the findings.
