You should immediately contact a family law attorney who is experienced with contested paternity actions. Since you were married to the mother, took the child into the home and you are on the birth certificate, you are the presumed father of the child. Your rights will be superior to any rights which are asserted by the other person. If you have been through the divorce process and there are court orders in place which show that you have custodial rights to the child, it will be even more difficult for your wife to set aside the paternity. There have been numerous cases that are similar to yours in California and the law is fairly clear that you will maintain your status the natural father of your child.
