I believe a close member of my family bought a house in my name and now the home is in foreclosure. ?

I went to get a line of credit at a bank and they denied me because I had a judgment from at-t for $333 and from a mortgage company for $166k. Only ociation I have with this address is I lived there in the first year the people purchased the home and that I receive mail there. I did not sign anything for these things. And when I confront the relatives they lie and blame others for doing this when they are a known compulsive lier (sp). Can a lawyer help me fix this problem or without proof am I out of luck. Can I have a notice put on my credit report ? what steps can I take to possibly protect my self? I'm only 25 and already been through a bankruptcy at age 23 because of this person stealing my credit. Fyi I have no proof but word of mouth from others he's done this to. I'm sorry if this doesn't make sense I'm tired and still in shock of finding this out.
