Legal Question in Family Law in Illinois

Not sufficient information and parts of this doesn't make sense. But here's the thing: it may be legal if he's the owner. You need to take the first step then and talk to him, and if need be file for divorce to protect your interests in the house. Because if he's paying the "mortgage" but you've been paying for anything for the house (taxes, insurance, upkeep, etc.), you have at least some equitable interests to protect. You'll have to bring all the facts and information to an attorney who can sort through this with you. If you do talk to him first, my suggestion is that you just find out what's up and "why now"....and what his plans are, and make no veiled "threats", because if he's fed up or just wants out, he could stop paying the mortgage to have you over a barrel -- on the other hand the house may be worth less than the mortgage today.... It's just really unfair that he didn't discuss this with you first but then again maybe that was the problem to begin with -- he sounds like a controlling individual, even if he may be caring enough to keep a roof over his kids' heads. Good luck!
