A clause at the end of a document, in particular a will, which
sets forth the legal requirements the document must satisfy,
states that those requirements have been met, and is signed by
one or more witnesses. An attestation clause strengthens the
presumption that the requirements have been met. See, e.g. Keely
v. Moore, 196 U.S. 38 (1904). Definition from Nolo’s Plain-
English Law Dictionary A provision at the end of a will or other
legal document that sets out the legal requirements of the
document and states that those requirements have been met. By
signing the attestation clause, a person is stating and
confirming that everything within the clause is true. Definition
