I live in and got divorced in Illinois. Our house was ordered to be sold in the divorce decree. I was to assume all losses on the house sale, which were going to total about $25K if I couldn't get a FSBO and needed a realtor. My ex wants now to refinance the first mortgage and is willing to pay off half of the second to do that (we each pay $14K to pay that off). Do I need to file a change to the order in court reflecting what it is he wants to do?
