DO NOT DEAL WITH THESE CROOKS! Good thing you have a lawyer. Fill him in and give him some of the cases established against them.
Do a google and look at how many times they have been sued. They are somehow related to another group called Weltman Weinberg and Reis. WWR is a junk debt buyer and not a law firm as they allege in letters. Some of the cases I read about on line listed both Wolfson and Weltman as co-defendents.
Look at the intent to sue. Did they actually file paperwork? Is there a court signature? Whatever you do don't sign for anything and really look at the stories on the net about the illegal activity from these firms. They tried to use a document easily downloable on line from the Special Civil Court to scare me into providing personal information. I went to the court clerk with a letter from the originating creditor to counter-sue on my own and lo and behold there was no law suit and they never filed the paperwork.
I was quoted $5,000 to get a lawyer to take my case and I just don't have it yet. Just beware, and don't deal with them.
Maybe your lawyer can send them a letter to cease and desist.
