Documentary evidence is any evidence that is, or can be, introduced at a trial in the form of documents, as distinguished from oral testimony. Documentary evidence is most widely understood to refer to writings on paper (such as an invoice, a contract or a will), but the term can also apply to any media by which information can be preserved, such as photographs; a medium that needs a mechanical device to be viewed, such as a tape recording or film; and a printed form of digital evidence, such as emails or spreadsheets.

Normally, before documentary evidence is admissible as evidence, it must be proved by other evidence from a witness that the document is genuine, called "laying a foundation".

As a general rule of evidence, a document shall be proved by primary evidence that is document itself. No oral evidence of content of documents shall be admissible. But in certain circumstances the secondary evidence of documents including the oral evidence can be given. For instance, when original is lost or is in custody or possession of person against whom it is sought to be proved.
