Post-placement portions of adoption evaluations, and combined pre - and post-placement evaluations (initiated after a child is already residing in the home, such
as in stepparent adoptions), are done by court appointment only.
In a stepparent adoption, a parent's new spouse adopts a child the parent had with a previous partner.
A difference between stepparent adoption and traditional adoption is that
in stepparent adoption the parent that has custody and is promoting the adoption had a prior relationship with the birth parent... and chances are very good that this relationship is fraught with a lot of negative feelings.
In stepparent adoptions, usually, the birth parent has not been active in the child's life prior to the adoption.
