Question: If my unwed son is named the father on the birth certificate but doesn't feel he's the father, is he legally obligated? Answer: This is an odd situation: generally, the hospital will not name a father on the birth certificate of an unmarried woman UNLESS the fathers signs a voluntary acknowledgement of Paternity ( a "VAP") . If he signed a VAP then yes, he is legally obligated to pay support and he has parenting rights. If he did not sign, he should file court papers and ask for DNA testing to confirm paternity. Consult an experienced family law attorney soon.
