Hi millenia, and welcome to business-talk.
I'm not too sure of the actual legal position - but where legal matters are at stake I would always recommend the professional advice of a solicitor - especially in this instance.
If you're lucky you might be able to get a good answer no the phone - but if you actually have to go in and chat then at worst it'll hopefully cost you no more than £200-£300 - for a legally qualified answer.
Good luck in your search.
