My father passed away in May. We have told lawyers repeatedly this and after 4 months of telling the mortgage company to foreclose and auction off the home since we couldnt sell it, I have been getting several letters from this company harassing a dead man over a foreclosure on his home. He was a US veteran and honestly if I had wanted to move myself and my husband away from the rest of the family we have I would have moved into his home but I couldnt do that. Instead I have called this firm and returned letters stating that he is deceased and to quit calling my number about this case as I am not even the executor of his will nor his estate. At least the other lawyers I have dealt with since his passing were nice and compassionate and said they would close any case he was involved in or take his name off of them as he was deceased.
