The finalization hearing, sometimes held in the judge's chambers, usually lasts less than an hour, and is attended by the adoptive parents, the child, the family's attorney, and a social worker from the child's agency. The judge may review the family's homestudy, ask questions, and generally attempt to ensure that the child is being placed in a safe, loving home.
When my wife and I adopted our son, we were told that we needed to hire multiple attorneys. One to represent the birth mother. One to represent the child. One to represent the birth father. And one to represent us. When we adopted our daughter we needed even more. One for the child. One for the birth mother. One for us. And one for each of the three possible birth fathers! We were outnumbered! Since no agency was involved, the attorney fees, the home study and the court costs were our only expenses. And when it came time to file our income taxes we claimed the adoption tax credit and were reimbursed the entire amount. Both times. We were fortunate. Adoptions can be, and in most cases are much more expensive.
