You would need to meet with an attorney to discuss a strategy to proceed with your situation.
If you are not on the mortgage(or any mortgage) you are not liable for the debt and possible judgment.
However-you will be named in the foreclosure lawsuit because you have an interest in the property as your name is on the deed.
Many attorneys spend a lot of time on foreclosure defense, short sales, and loan modification law.
You have many opportunities in this stressful time in your life.
The answer given does not imply that an attorney-client relationship has been established and your best course of action is to have legal representation in this matter.
I agree with Attorney Pippen. You need to consult with a lawyer and take care of this right away, if you have any hopes of retaining the home. Whether you are on the loan agreement or not is not really relevant. Because the lien attaches to the property, and this is a secured debt, if you do not make payments, the lender can foreclose on the house. If that happens, you will have about six months to vacate the property.
There may be other options, as Attorney Pippen alluded to, however. You should explore these with a probate/real estate attorney as soon as you can.
*** LEGAL DISCLAIMER I am licensed to practice law in the State of Michigan and have offices in Wayne and Ingham Counties. My practice is focused in the areas of estate planning and probate administration. I am ethically required to state that the above answer does not create an attorney/client relationship. These responses should be considered general legal education and are intended to provide general information about the question asked. Frequently, the question does not include important facts that, if known, could significantly change the answer. Information provided on this site should not be used as a substitute for competent legal advice from a licensed attorney that practices in your state. The law changes frequently and varies from state to state. If I refer to your state's laws, you should not rely on what I say; I just did a quick Internet search and found something that looked relevant that I hoped you would find helpful. You should verify and confirm any information provided with an attorney licensed in your state.
I agree with both attorneys here. I do wonder if the lien is valid since they did not include you in the modification loan. I would seek the advice of someone who has done alot of the loan modification/foreclosures issues.
