My son is 3 years old. I didn't know about that he was mine or see him until he was a little over 2 and a half years old. The mother only recently told me that he could be mine and that I had no legal rights to my son. Her wife/civil union partner adopted him. What can I do I did the DNA test and he my son how can I get my son back in my life and try to have the adoption contested? I live in New Jersey. The adoption was done under the conception that the child was a result of artificial insemination.
