I just found out that when we bought our house in Spring Valley in 1995, the bank recorded our mortgage against the house across the street, not the house we bought. It appears to be a real error on the bank's part. The bank is now suing to force us to sign a corrected mortgage. It seems to me that they made a mistake and now they have to live with it. My house does not have a lien on it, correct? Do I have to sign the corrected mortgage, or should I hire a lawyer and fight this? Do I have any grounds to fight this? I know I have a note but do I have to sign a corrected mortgage? Shouldn't the bank live with its mistake just like everyone else has to live with theirs? Does the bank have a time limit?
