since nobody has standing to challenge a foreclosure, nobody can do anything to forestall the foreclosure.

If the house is secured by a deed of trust, the lenders actions are quite simple; they already have a right to sell upon default. If there is a secured mortgage the method is a bit more involved but not so much it would slow the bank down much.

about the only thing that would delay the process would be to open probate but even then, the lender is not required to delay their process anymore than they choose to. You are at the whim of their sympathy.


Respond to requests from the mortgage holder or not?
it would make no difference since anybody responding would have no legal authority to object to anything or even address it. In other words; they aren't going to care because you don't make a difference in this situation.

My inclination is not, limit contact to in writing only and answer no questions, only ask them for documentation that they own the mortgage.
so you intend on impersonating your father and intentionally causing the lender damages? Is that what you are suggesting?
