Unmarried couples in a live-in relationship must register it with the government within 30 days of moving in together. The registrar reviews the application and may ask for additional information during an investigation. If approved, the relationship is recorded in a register and a certificate issued. Refusal to register may occur if one partner is married, a minor, or if consent was obtained through coercion or fraud. Partners can end the relationship by notifying the registrar and their partner. Failing to register the relationship or providing false information can result in fines, up to 3 months of imprisonment, or both.
