Civil Law Procedure
A person who wishes to file a lawsuit against someone must go to the appropriate court registry and submit a writ of summons together with a fee of 3% of the sued amount. (If the plaintiff wins his case, the defendant must pay this fee. The Court may also charge attorneys fees to the loser).
The Court will send the summons to the defendant by means of process servers employed by the Court. If the defendant is not found, the summons may at times be left with relatives or at the defendant’s usual place of abode.
