What kind of lawyer do I need when your mother and sister are slandering my name?

My sister and mother have been telling people that I lie, steal. They have made several false reports to social services trying to get my kids taken from me. I now live in Florida because they caused my kids and I to get kicked out of where we were living in North Carolina. My sister has stolen a 4 wheeler, an electric scooter, my son's remote control dinosaur, a computer and numerous things out of my father's she'd and sold them in a yard sale that she had to get donations for a church ministry she started called Hearts of the afflicted it's a laundry for the homeless ministry. There's so much more. This has been going on for years.
