Depending on that, the attorney can advise you what can/should be done.
As realtors, we are not supposed to give legal advise. We can advise on many things that have to do with real estate and the process of buying/selling though.
If you have a combined hardship and the property is under water (I just had a similar situation - it was an ex boyfriend who was without a job), you can sell this property via a short sale.
Hope this helps,

You can also tell him he can pay the monthly mortgage by him self if he doesn't want to consider selling. It's not fair to you unless he has a strong reason not to sell.
