Attestation Definition

The act of watching someone sign a legal document, such as a will or power of attorney, and then signing your own name as a witness. When you witness a document in this way, you are attesting -- that is, stating and confirming -- that the person whom you watched sign the document in fact did so. Attesting to a document does not mean that you are vouching for its accuracy or truthfulness. You are only acknowledging that you watched it being signed by the person whose name is on the signature line.
