Legal Question in Real Estate Law in Illinois

I am sorry for your loss. It depends on how title was held and whether there was a will. If you were both owners, and you were joint tenants or tenants by the entirety, nothing needs to be done--the property belongs to you. If you were not an owner, or if you were tenants in common, and if your spouse had a will, the provisions of the will control. If there was no will, then you and the children would take what your spouse owned. You should contact a probate or real estate attorney in your area to determine what, if anything, needs to be done.
