Hello Rachel and thanks for your question.
After having read Carlos's brilliant suggestion and the web address that followed, I certainly think that it's worth both your time and money to invest in having a paralegal or real estate attorney advise you in this particular tactic. So far as I can tell, there's nothing illegal about the request, and providing proof of ownership as well as other documents necessary to verify any legal claim is "standard procedure" in most court cases. I would only caution you, however, that California, New York and Florida, for some peculiar reason, tends to thave slightly different laws than in the other 47 states, so it would be advisable to get legal help to protect your home and not attempt to do this alone.
Good luck in delaying the foreclosure, and, Carlos, you have brought to light an extremely useful tidbit of information.
