Removing Mother-in-Law from house.

Location: Texas

I am 34M and my Fiancé is 41F, and her 2 kids 17M and 18F. We are in Texas (North Dallas area) We are renting, and only me and Fiancé are on the lease. Also, this is relevant. My fiancé and family are Black and I am White.

When I moved in with her family, her mom moved out of the house. This was about a year and a half ago, but when my step-daughter graduated she snuck her way back in. She came to stay a couple days for the graduation, then she had a client in the area (she is a caregiver/sitter) and asked is she could stay until the weekend. I agreed, but said after that she needs to leave. Well, she stayed long and kept guilt tripping my fiancé to let her stay.

I had talked to her about paying $200 to help with bills, and we asked if she would move out before our wedding at the time in 6 months. That was 2+months ago. Today I asked about the $200 to help with bills, and she blew up saying how she supported my fiancé before I came along. I am drowning, consistently over-drawn and 2 maxed out credit cards. I’m am the sole income. Hence, why I asked for a little help.

She went on a tirade and started saying how this is how white people do, and calling me multiple names. I am Atheist and she would consistently call me satan and says god will smite me. It never really bothered me, but I have never said anything back. Today I had enough. This has already caused a rift in her family, and our wedding in 3 months no longer has a venue. Fiancé’s brother now states we can longer have the wedding/reception at his house, because he will only believe his mom. They don’t want to take his mom either.

So is there something I can do about having her removed from the property since she is not on the lease? I can give notice, and she says she would refuse to leave regardless. I really don’t want to have to call police to remove her. Also, should i inform the landlord about this and her refusing to leave?
