Dude... sorry to hear that.
:-(
Yep, as mentioned, get a solicitor involved. I can recommend a matrimonial/family (I know you're not married, but same area) solicitor at the place I work. I think they offer a free 30 minute initial consultation, at least they used to a while back, no-one's mentioned anything about it recently, I'll have a word in the morning. Could be useful if you're just looking for a few pointers to get started with.
