Here’s what the story says:
You know the type: the borrower’s lawyer contests foreclosures by challenging every aspect of your Complaint; he raises MERS as an issue when MERS is not even named in the mortgage; he serves boilerplate discovery requests (likely downloaded from the Internet) seeking documents about securitization when the loan was never even pooled or securitized; he requests the depositions of everyone involved with the loan; he sends nasty letters every other week making baseless threats and/or threatening to contact the media; he appeals adverse decisions whether or not there is any merit; he claims that documents have been robosigned – a term he likely stumbled upon unwittingly while browsing the Internet for ways to defend foreclosures.
He does this to create delay; to run up your costs in order to leverage a favorable resolution such as a loan modification, short payoff, or principal forgiveness; and/or out of pure spite.
