How long might it take for me to adopt an infant with my partner?

First, have you thought about foster/ adopt children. In this program you would be taking care of children in your home with a goal to return home which generally doesn't happen because parents fail to follow their service plan, have no desire to regain their children, and the court terminates their rights or they sign off on their rights. Then you have first chance to adopt that child in your home. There is no charge to adopt . If interested check with your state CFS agengy. In all 98% of all adoptions are done this way.
