My Mom Moved In With Me, Now Says I Can’t Make Her Leave Because She “established Residency.” I Feel Trapped.

Long story short, my mom has made a lot of bad decisions over the years and ended up alienating herself from me and my sisters. A few months ago, she moved out of state to live with a guy she met on TikTok. That situation fell apart, and about two months ago she came back with nowhere to go.

She’s currently homeless, so I let her stay with me because I didn’t want her on the street. I live with one of my sisters, and things have gotten really complicated.

Living with my mom has been extremely difficult. It’s honestly affecting my mental health and causing me to fall back into habits I’ve worked really hard to unlearn. I finally set boundaries tonight and told her that if she can’t follow the rules of my home, she needs to leave.

She responded by saying I can’t kick her out because she’s been getting mail sent here, so she’s now a “resident.” She also threatened to sue me.

Side note: she’s also been extremely picky about finding full-time work, even though she doesn’t really have formal education or solid work experience. I feel like she can’t afford to be picky right now because the sooner she has stable income, the sooner she can move out. Every time I try to say this, she tells me not to tell her what to do. Tonight I snapped and told her I will tell her what to do because this is my home and I don’t want her here long-term. I just want her to get on her feet and leave, and it feels like she’s not taking that seriously.

On top of that, my sister I live with has a very strong emotional attachment to my mom and wants her to stay no matter what. She’s now threatening to stop paying rent if I force our mom to leave, which could get all of us evicted.

So now I feel completely stuck. I don’t want to make my mom homeless, but I also feel like my home isn’t my home anymore. I dread being here every day.

Do I actually have any legal standing here since she’s not on the lease? And how do I handle this without everything blowing up?
