262. If the formalities required to establish the validity of an exhibit or other document were not observed, a party may, not later than at the time of setting down for trial and judgment, ask that the exhibit or document not be admitted in evidence. The party may also do so if it disowns the exhibit or document, does not recognize its origin or contests the integrity of the information it contains.
A party that intends to contest the origin or integrity of a document must specify, in an affidavit, the facts and grounds that support the party’s claim and make it probable.
