Evidence (law) - Authentication

Authentication

Certain kinds of evidence, such as documentary evidence, are subject to the requirement that the offeror provide the trial judge with a certain amount of evidence (which need not be much and it need not be very strong) suggesting that the offered item of tangible evidence (e.g., a document, a gun) is what the offeror claims it is. This authentication requirement has import primarily in jury trials. If evidence of authenticity is lacking in a bench trial, the trial judge will simply dismiss the evidence as unpersuasive or irrelevant.
