House under contract, could I file for divorce and not risk the deal falling through?

I would suggest seeing an attorney experienced in family law before making any major decisions.  Perhaps you should also look into divorce mediation. You can save an enormous amount of money, time and stress if you and your husband can mediate. Once you file for divorce, there are automatic orders that take effect. One of these is that neither party can sell away marital property. However, I don't think it would be a problem as long as you and your spouse are in agreement on the sale and the nature of the distribution of the proceeds. Feel free to contact me if I can be of further assistance. Best of luck and happy holidays. 203-870-6700
