The Criminal Courts rule over all crimes under its jurisdictions. The “Shari’a” courts have exclusive jurisdiction in connection with all family law matters.

The Government of Qatar has been keen to support and organise its legal system along contemporary lines, therefore its legal system is rooted in the Napoleonic Code which was adopted for the Middle East by Egypt.  Judges are independent and their decisions are taken and implemented in accordance with the law. The court proceedings are open to the public unless the court decides of its own accord or at the request of an interested party to hold them in closed session. if that would best serve the interests of the public or general order. In all cases, sentences are pronounced in public sessions. Arabic is the official language in the courts of law in Qatar, but the courts will also hear evidence given by non-Arabic speakers  and witnesses through an interpreter, who are required to take an oath and obliged to observe all honesty, integrity and sincerity.
