Tenant refuses to sign 60 day termination notice

[Daniella Spears]

Help me out BP fam!! I rented my home to a friend(bad idea I know), and it was a pretty laid back agreement..month to month lease..no deposit..cash randomly and not documented properly...etc. In fact, I don"t have the lease, but she is behind, has cats that pee everywhere and smokes and so I tried to talk with her and have her sign a 60 day termination letter, but she refuses to sign it. She says she is not going to be homeless and i have tried to illustrate to her that I just simply can not afford to support her and her family as I am a single momma as well.  What do I do? Can I evict her? What all proof do I need to win this lawsuit?! Do I need to get a lawyer? Any advice is much appreciated!!  I live in Georgia btw.

TIA
