Attestation
ATTESTATION
The act of attending the execution of a document and bearing witness to its authenticity, by signing one's name to it to affirm that it is genuine. The certification by a custodian of records that a copy of an original document is a true copy that is demonstrated by his or her signature on a certificate.
An attestation is a declaration by a witness that an instrument has been executed in his or her presence according to the formalities required by law. It is not the same as an acknowledgment, a statement by the maker of a document that verifies its authenticity.
An attestation clause is frequently found in legal documents that must be witnessed if they are to be valid, for example, a will or a deed. It states that the instrument has been completed in the manner required by law in the presence of the witness who places his or her signature in the designated space.
