My question involves grandparents rights in the State of: Tennessee. My Sister in Law has a drug addiction problem and she has been suicidal and violent. She has a daughter and the biological father still has rights, but we cannot find him. I would like to know how I can legally have temporary custody immediately until she is better. She checked in to a detox center, but she signed herself out this morning. She did not make it 24 hours. Please help.
