Legal Question in Real Estate Law in Illinois

Without knowing what you hope to accomplish, it is hard to say. It seems unlikely you did not sign the mortgage if you are an owner, but it is possible you are not responsible for payments. Depending on your goals, you may want to contact a real estate attorney or probate attorney.

You did not really say what it is that you want to address, but co-ownership situations can create all kinds of questions should your relationship end. So, it would be important to sit down with an attorney experienced in contracts and real estate to draw up an agreement governing your ownership, possible buy-out or sale requirements, etc.
