Presumption of authenticity for documents - contents and signatures treated as genuine unless contrary evidence is produced. When a document produced, seized, or received from outside India is tendered by the prosecution against an accused, the law presumes the truth of its contents and the genuineness of signatures and handwriting, and presumes execution or attestation by the person it purports to be from, unless disproved; such a document may be admitted even if not duly stamped, if otherwise admissible.
