Section 67 of IEA : Section 67: Proof of signature and handwriting of person alleged to have signed or written document produced.

Explanation using Example

Example 1:

Ravi claims that a promissory note was signed by his friend, Suresh, promising to repay a loan of ₹50,000. Suresh denies having signed the document. To prove that the signature on the promissory note is indeed Suresh's, Ravi brings in a handwriting expert who compares the signature on the note with other known signatures of Suresh. The expert testifies that the signature matches Suresh's handwriting. This evidence is used to prove that Suresh did sign the promissory note.

Example 2:

Meena is involved in a property dispute with her cousin, Anil. Anil presents a will that he claims was written and signed by their late grandfather, bequeathing the property to him. Meena suspects the will is forged. To challenge the authenticity of the will, Meena's lawyer calls upon a forensic document examiner who analyzes the handwriting and signature on the will. The examiner compares it with other documents known to be written by their grandfather and concludes that the handwriting and signature on the will do not match. This evidence helps Meena prove that the will is not genuine.
