I live in Texas and when my son was 18 months old I was sent to rehab. I signed over temporary custody to my sister. I later, about a year and a half ago) signed over all rights so she could adopt him.He has now just turned 4. I have since changed my life completly and I think I could raise him better than her. The adoption isn't even finalized yet is there anything I can do to get my son back. I don't have money for a lawer-but she isn't a good mother at all! Please help me.
