Well Gumtree (part of Ebay) has heard of them
http://leicester.gumtree.com/leicester/41/8791341.html amongst many gumtree pages.
But it seems no-one else has.
Follow the info below, and I think it is a one man band setting up a franchise.
Still no number though.

So quite probably, all the above info may be irrelavent.

Thanks for the info, lompos. I tried the Betteridge number, but there was no connection to Future Legal Services. In fact, they gave the impression that they had never heard of them. However, they did say that they offered legal services, perhaps they thought they had a new customer.
