2. The domain name is quite specific to the trading name of the client. However, I don't think that it is a legally registered name - not a limited company (UK based).
I don't know what to say... if your client has a line-item invoice which shows they were billed for the registration transaction, you might have a good case.
I really think your best bet is to determine if its worth fighting over first; if so, contact a trademark or property rights lawyer; if not, move your site to a new domain name.
