A:
If the reality is as you mentioned,
that you divorced your wife and when you found that she did not leave the house you told her that you had divorced her and repeated this in front of the police officer whom you called to evict her from the house, this is considered one pronouncement of Talaq (divorce pronounced by a husband) (Part No. 20; Page No. 248) because, in this case, the second and third pronouncements were confirmation of the first pronouncement of Talaq. You can return to her with a new contract and a new Mahr (mandatory gift to a bride from her groom), provided that she gives her consent to remarry you and this has not been the third pronouncement of Talaq. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
