Article 10 of Law Regulating Expert Services

The expert shall commence his work at the time specified in the judgment or decision. If he is unable to do so, he shall set a date for commencing his work no later than seven days from his receipt of a copy of the judgment or decision or the case file, and shall notify the litigants of the date and place of appearance before the expert, through the process servers in the Department, by registered letter, by telegraphic message, by written telephone message (fax), or by any electronic means provided for in Law No. (20) of 2014 concerning Electronic Transactions. Where it is established that the litigant was served with the statement of claim through the Public Prosecution, the expert may notify him to appear through the Public Prosecution. In all cases, the expert shall carry out his work even in the absence of the litigants, provided that they have been duly notified.
