My partner has just found out that he is not the biological father of his daughter who is 11. He has parental responsibility and a contact order. Her biological dad has appeared from nowhere and now my partner is being refused contact please help. He can't just wipe her out of his life

ANY question on law needs to include your general locale as laws vary by area.

Your partner should contact a Family Law specialist. Depending on local laws his status as the legal father may no longer be changed. He would probably have to go to court to have his rights enforced.
