Also, if your husband doesn't make the mortgage payments on your first mortgage, your credit will be affected. If you are just about to go into the divorce, it would be a good idea to get a copy of your credit report (it's free without the scores at www.annualcreditreport.com) and review it. If your credit is good now, and you have mostly joint credit, it would be a good idea to try to establish your own before the divorce.
Not exactly an answer to your question, but hopefully it helps.
