Which term is the clause at the end of a will where witnesses certify due execution?

Detailed Explanation

Attestation clause is the witness-certification clause, often at the end of a will. In the booklet's "Attestation Clause" definition, it is the clause wherein the witnesses certify that the instrument was executed before them and the manner of execution. Not to be confused with a jurat, an attestation clause is not the officer's certificate that an affidavit was sworn before the officer.
