What happens after 12 months and CPS case is dismissed?

At 12month mark(march 08) biodad had done NOTHING and had charges pending. Biomom had done a little. So we hired an attorney. We had mediation, which neither BP's showed up to, but BM participated by phone. Saying that her and BD refused to relinquish. We went to court there was NO extension granted, we declined PCM and TPR hearing was set. TPR was granted, they appealed and we did not have the final TPR paperwork and ok to adopt until January 09. We did not adopt until May 09! So everything takes a while. I would get the advise of an attorney tho. Also I think it depends on the age of the kid. Ours was 4 months at time of removal...so they had pleanty of grounds to tpr on, starting with best intrest of the child. They filed departmental abandonment on the BF since he had not been in contact with CPS or us. Is there an ad-litem? Ours was so INCREDIBLE! He really helped us with everything!
