What legal papers would I need? My sister in law tried to give her son to the babysitter said she didn't want him anymore. She is always in and out of jail and her mother cares for the baby she is getting too old for young kids, we want him and are family. When she gets out of jail we are going to have her sign him over to us we will give him everything he needs and hey he'll have brothers! But I need to know if she can sign a paper stating she is giving us custody or if we need a legal document
