Hello ladies! Have you ever encountered such a situation? My husband was married before me, they had a daughter together. It turned out that this is his child, so he divorced his ex-wife. However, according to the law, this girl is registered with him. Now we want to challenge paternity through court. If she refuses DNA testing ?, will the court force her? How long will this process take? We plan to move abroad in June and want to resolve everything before then! And how much will it cost? Has anyone else faced such a situation?
