From my experience, just because you leave the house, that doesn’t exclude you from payments as long as that house mortgage still has your name on it. Unless your separation papers specifically say you are not liable for that debt, you still are obligated to pay. A quit claim sign over only says you have no CLAIM on the house. It doesn’t exempt you from any payments unless your ex refinances the house. That is my understanding and my experience. I paid the total bills for my house after my separation/divorce. I didn’t want my credit ruined more that it was (due to my ex). It took over a year to clean my credit enough for me to refinance. ANYTHING still in your name and your ex’s will be tied to you. If he defaults payment, then the creditors will look for the other person on that loan/bill…which is you.
You didn’t go into much of what your separation papers said or how they might have protected you from this. I DO know that someone’s word is not worth crap…even if you were married to them for 27 years. In cases of divorce, you MUST have signed documentation. Promises and “I’ll take care of it” can’t be trusted.
Keep on your lawyer. Hopefully he will come through for you. If not…get a better lawyer.
