Article 32 of Law of Evidence

A challenge on grounds of forgery may be brought at any stage of the action. The challenger shall specify every alleged instance of forgery, his evidence and the investigative procedures by which he requests to prove it, in a memorandum submitted to the court or by having it entered in the hearing record. If the challenge is material to the dispute, the facts and documents of the action are insufficient to convince the court of the authenticity or forgery of the instrument, and the court considers the investigative procedure requested by the challenger to be material and permissible, it shall order investigation by comparison, witness testimony or both, in the manner set out in the preceding articles. The party against whom the forgery challenge is brought may halt the investigation at any stage by abandoning reliance on the challenged instrument. In that case, the court may order the seizure or retention of the instrument if the forgery challenger requests this for a legitimate interest.
