In order to confirm the right, the real estate department needs the applicant to show his identity card, household registration book and marriage certificate (or single certificate) when handling the real estate license. If he applies for a real estate license before marriage and has a single certificate, only one person needs to sign it. If it is after marriage (including after divorce), the property right department cannot determine whether the property right is owned separately, that is, whether the property right of the house is controversial (the divorce agreement does not indicate the property ownership). Therefore, it is correct to apply for the title certificate now, and your original spouse needs to write a declaration of abandonment of property rights. The property department acts according to the current marriage law, that's right.
