Probative value of private documents signed by the author or witness

Probative value of private documents signed by the author or witness Private documents, only signed or “affirmed” by the person in whose name they are made, shall constitute proof against the signatory, if they are acknowledged by him or by his heirs and legal representatives; but if they are signed also by two witnesses, whose names have been mentioned in the text of the document, shall constitute prima facie proof, which may be confirmed by their oral evidence before the Court.
