Unfortunately, generally, without any written document stating that the ex had agreed to release her ex-spouse from the court ordered obligation to make payments on the second mortgage, the court can still hold the non-paying spouse in contempt and generally, the only defense in similar situation would be laches, which is a legal term for unreasonable delay in making an assertion or claim, such as asserting a right, claiming a privilege, or making an application for redress, which may result in refusal.
So, given the seriousness of the situation, it is important to consult and retain an experienced local family law attorney to represent you at the contempt hearing, to make sure that your rights are fully protected and your position is represented in the best possible light to the court.
