How do you handle the expenses of a house or something else while you’re trying to sell it?

You both took the risk and potential benefit of the house together, and if you’ll be sharing equally in the equity when the house sells, you can’t have your cake and eat it, too. If one of you doesn’t yet have your own financial resources, you can agree in writing in your divorce agreement that the other will advance money to the household to be prepaid when the house sells and the equity is distributed.
