How to prove forgery in court ? supreme court judgments on forged signature ?

In India, if a signature on a document is suspected to be forged, the party alleging the forgery can file an FIR with the police or a complaint with the court under Section 465, Indian Penal Code, 1860 which punishes the offence of forgery with imprisonment for a term which may extend to two years, or with fine, or with both. The following are the steps to prove that a signature on a document is forged:

1. File a complaint: The first step is to file a complaint with the police, providing them with the necessary evidence, such as the original document, the alleged forged document, and any other relevant evidence. The police will initiate an investigation and may also seek the help of handwriting experts to determine whether the signature is forged or not.

2. Expert Opinion: If the case goes to court, the party alleging forgery can present the opinion of a handwriting expert who can examine the signature and testify in court about whether the signature is genuine or forged. The court may also appoint its own handwriting expert for an independent opinion.

3. Comparison of Signatures: Another way to prove forgery is by comparing the signature on the disputed document with other documents that are known to have been signed by the same person. If the signature on the disputed document does not match the signatures on the other documents, it can be considered as evidence of forgery.

4. Cross-examination of Witnesses: The court may also cross-examine witnesses who have knowledge of the signature, such as witnesses who were present when the document was signed, to determine the authenticity of the signature.

Once it has been established that the signature on the document is forged, the court may take appropriate action, such as declaring the document null and void, and initiating legal action against the person responsible for the forgery.

The Supreme Court of India has consistently held that dishonest intent is a crucial element in proving forgery. Simply proving that a signature or document is false is not enough unless it is shown that the act was done with the intent to deceive. In civil cases, the standard of proof is the preponderance of probabilities, while in criminal cases, it must be proved beyond a reasonable doubt. The court has also clarified that not all false documents automatically constitute criminal forgery unless accompanied by fraudulent intent.
