I want to file a case to the kuwait family court,...

 Please be kindly informed that according to the data provided to us in your inquiry and with reference to the Kuwaiti Personal Status Law that regulates personal status matters and the effects on it first, the family court specializes in the legal issues and therefore any illegal marriage contract does not have jurisdiction over it. This can be established in front of the embassy to which it belongs or in the country where the marriage contract is located, so we recommend that you visit the embassy that belongs to it and inquire about the details, noting that the complaint can be submitted to the wife if the marital union is established in front of the nearest police station and explain the matter in detail for the purposes of legal treatment
