If the father is not on the birth certificate does the father have to sign anything for the mothers husband to adopt the child?

Whose name is on the birth certificate then if the childs birth father isnt. Thats the person you need to sign. Check with your state city hall or adoptation office and see. It may be very easy.

If you never married the father and the father is not named on the birth certificate then you do not need the fathers consent for your husband to adopt the child. You may be able to pay a small fee and just add your husbands name on the birth certificate. You can call the vital status and ask them what you need to do. The father can if he wants take a DNA test to prove parenty and ask the court for visitation if he knew of your intent,but it's been three years so it does not sound like you have to worry about that. if you let your husband adopt your child or add his name to the birth certificate then he will be responiable for this child until the age of 18,19,or 21 depending on the laws in your state.

While the answer to this question can vary from state to state, many states are now going by the Uniform Parentage Act (2002). This Act adds clarity to presumed paternity vs. biological paternity and DNA testing's effects on old laws. In a case where a couple is married at the time a child is born, there is no need for adoption. A mother can add her husband's name to the birth certificate as he is legally presumed to be the father of her children born during the course of her marriage, unless otherwise disproven. The UPA (2002) does allow for a biological father to disestablish the presumed paternity of a child but it must be done within 2 years of a child's birth. Allowing many years to go by & then dis-establishing the paternity of a child when the husband & wife are living together & raising this child & the child knows the husband to be the "Dad" is not in the best interest of the child. Even in states that have not adopted the UPA (2002), if many years have passed since the child's birth & the biological father has not acted, unfortunately, he will have likely run out of options.
