Anybody legally knowledgeable / qualified?

"UK law" is actually non-specific; it depends on the country in which you live. It might be a good idea to get an appointment with your local Citizens Advice Bureau if you haven't already done so. It depends on how serious it is of course. I'd also say that other legal counsel may be a good idea; many law firms offer them for free, to determine what area of law is best suited for your needs. You can then proceed from there.

I'm not saying there's not anyone here qualified to help, but perhaps consultation with a verifiably qualified law firm or body (such as the CAB as mentioned earlier) may be your best course of action depending on your specific situation.
