Hi my name is ***** ***** I hope I can help. Are yall in the process of getting divorced? If so, you can speak with your lawyer about this. If not, I would suggest seeking out legal counsel to have them assist with her residing in the home. You would need a judge to determine her staying/leaving. Once you have a judge's order, she must follow it - if she doesn't then it provides you more leeway to contact the police and have her arrested for trespassing. Until you have a court order, there's really nothing you can do to get her to leave (unless the house is only in your name... then she technically doesn't own the home and you have full power to have her removed from the home).
