La. Civ. Code art. 1836
Current with changes from the 2024 Legislative Session
An act under private signature is regarded prima facie as the true and genuine act of a party executing it when his signature has been acknowledged, and the act shall be admitted in evidence without further proof.
An act under private signature may be acknowledged by a party to that act by recognizing the signature as his own before a court, or before a notary public, or other officer authorized to perform that function, in the presence of two witnesses. An act under private signature may be acknowledged also in any other manner authorized by law.
Nevertheless, an act under private signature, though acknowledged, cannot substitute for an authentic act when the law prescribes such an act.
