from personal experience. although my case was in AL, best interest of the child still applied.
bio parent had not seen child in almost 2 years and had limited supervised only visitation prior to that due to neglect. 3 founded cases with CPS before custody was changed. child support in arrears 33k+
took almost 2 years and thousands of dollars and I still dont know what the outcome would have been if bio parent hadnt just given up and signed the papers voluntarily terminating her rights.
it is presumed that it is in the child's best interest to have both biological parents. If the absent parent fights the TPR, chances are they will be given a chance to make it right (ours was given almost 2 years of chances by the court) before TPR. The judge will most likely order supervised visitation, counseling, etc to try to reunite the child and absent parent. As long as the parent does their part and makes an effort, the judge will probably not terminate. In our case, biomom did not show for any of the supervised visits, counseling, etc. She would come to court with some excuse or another and the judge would give her another chance.
So, be prepared. It is heartbreaking. I watched that child get her hopes up over and over only to have her biomom crush her time and again. And this was after she had finally begun to come to terms with the abandonment. It all gets opened up again in a TPR.
I would do it again in a heartbeat, but please know that it is not easy and may not be successful. However, it may bring the absent parent back into the child's life and allow for a great bond between them - which is great. It may just be the wake up call the absent parent needs.
