In all states in the U.S., the consent of both natural parents is required for an adoption to take place, unless the parent is considered an “unfit parent” by the court. In that case, an adoption can go forward even without the consent of that parent. The rules for an unfit parent vary depending on the state, as each state has its own specific laws. However, in very general terms there are a few specific things that will normally render a parent "unfit."
Unfit Parents and Adoption
For the purposes of determining when a parent has abdicated his or her parental rights, and thus no longer needs to consent to adoption, the following things can be considered to make a parent unfit:
It is important to note that exhibiting these behaviors does not automatically terminate parental rights. In many cases, a child with an unfit parent will first be put into the foster care system so the parent can be given the chance to resolve his issues and reclaim his parental rights. In other cases, a parent may choose to willingly give up his or her parental rights.
Getting Help
If you are hoping to adopt a child and wish to prove his or her parents are unfit because they will not consent to the adoption, you will need a lawyer on your side to help make a convincing argument to the court.
