Adding father to birth certificate.
My some was born in Arizona and soon after his mother moved and filed for custody in California. The result of which awarding me primary physical custody and joint legal custody. The problem is my son is now 15 and my name was never added to the birth certificate. Even though I have primary custody mother is not consenting to voluntarily add my name. If birth certificate is Arizona and Custody order is California which court do I file in to have a judge order my name on the birth certificate?
