Adoption

My husband and I live in California. We adopted a child 2 years ago and we love him as our own child. But he has not able to get along with us or accept us as his parents. He does not seem to be happy living with us and he keeps saying he wants to end the relationship. Is it possible for him to terminate the relationship with us? If so, how?

I was adopted by my grandparents (my fathers parents) does that mean my father is my brother legally?

I'm married and my husband wants to adopt a child. What legal actions would need to be done to add parents' name on the adopted child's birth certificate? Would the original birth certificate be replaced by a new birth certificate?

My step-father adopted me. Is his son now my legal brother?

The biological father of my children is deceased and I have since re-married. I am reluctant to consider step-parent adoption because I understand that doing so would then erase my kids' natural father from their birth certificate and other records. We really would hate to do that. However, we do desire for my husband to be able to act as a legal parent - making medical decisions and consenting as only a parent is allowed to do. Is there any way we can accomplish this? Could he and I become co-guardians of the children?
