Mr...
There are many opinions on FDRS, both good and bad.
I would suggest you do your own research independent of this board and FDRS client care. I took the time to do this and learned some VERY interesting stuff. Needless to say, I am still enrolled in the program.
I don't expect it to be an easy road. This program uses the legal system. For that reason, I do expect to go to court. FDRS told me that the attorney network ASSISTS you at the state level. This seems to be true based on "mike's" information above. I also have contact with a couple of others in the program and they also have had good luck with the attorney network.
Also, be extremely careful(I can't emphasize this enough) what you say to debt collectors. You can unwittingly enter into a contract to pay a debt you don't owe. Then you
will get a judgement against you.
Review the Fair Debt Collection Act and the Fair Credit Reporting Act. Kind of boring reading, but vital to understanding the process.
The enrollment process is a little unnerving. If you are concerned about giving the information they request (I was) simply lock down your credit (I did) and nobody can open anything in your name (including you) without lifting the freeze. Although, I am guessing that since you are investigating the FDRS option, that you are done with credit cards anyway.
BTW, nobody has tried to open anything.
Finally, my experience with client care has been good. And, no, I don't work there.
I investigated debt settlement companies also. Almost went with one except... I didn't like their answers when I asked what they do if I get taken to court. Basically they told me they were not attorneys and I was on my own.

Also, although you may get to pay a lesser amount in a settlement, it is still on your credit for seven years and can't be removed because you validated their claim.
Good luck whatever way you go!
If you have any questions I will do my best to answer them.
