The Civil Court is located at Dafna and almost all taxi drivers know its location. You may need assistance there as everything is in Arabic. Go there with your family and with all documents. It is strange you were provided accommodation outside the airport and how was it possible for you to exit the airport. Who were the people misguiding you and putting you in this difficult situation? You should inform the court of this. Suggest you seek the assistance of your country's embassy in Doha if there is one here. You can find this out through Google. I guess you are in a real difficult situation.
