My question involves a marriage in the state of: Michigan
Hello,
My wife and I are on a path for divorce in the next year or two. The reason being is to keep her on my health insurance until she can (hopefully) get her own. She recently asked if I could move into my parent's house until she can afford a place of her own. I agreed to this. Later she said she wanted her sister to move in with her. Her sister is a compulsive lair and is leading my wife on with how much she's going to contribute financially. She has a very long history of destroying the places she lives in, stopping rent payments, and illegal drug use. She has attempted to manipulate my wife into giving her money several times. Each time I was able to dispel her illusions of need with my wife and by and large we've been unscathed.
To further complicate things we have a 2 year old son. Obviously from the above I don't want my wife's parenting time to be around my sister in law. However I know I can't control that. Mostly I just want to protect myself from having to evict my sister in law in the future. I'm very convinced if she's allowed to establish residency that's what it'll come to.
We purchased the house while married. However the mortgage is under my name alone, and my name alone is on the Title. I know that, in an extreme case, I can divorce ahead of schedule and sell the house to distribute the (very small) amount of equity we have in it. What legal grounds do I have have, if any, to stop her sister from moving in?
Thanks,
Will
