When attesting witnesses appear at an execution, unity of action shall be indispensable, to which the notary shall attest to in the deed. Provided, That when the execution only requires the presence of a witness with personal knowledge, who at the same time is not an attesting witness, said unity of action shall not be necessary. However, at the act of signing, there shall coincide before the notary, the witness with personal knowledge and the party making an appearance that the witness knows and identifies for the notary, who shall so attest to in the deed.\nHistory —July 2, 1987, No. 75, p. 242, § 24; Aug. 26, 2005, No. 80, § 1.
