attestation clause
attestation clause. A provision at the end of an instrument (esp. a will) that is signed by the instrument’s witnesses and that recites the formalities required by the jurisdiction in which the instrument might take effect (such as where the will might be probated). • The attestation strengthens the presumption that all the statutory requirements for executing the will have been satisfied. Cf. TESTIMONIUM CLAUSE. [Cases: Wills 113. C.J.S. Wills §§ 253–255.]
