Thanks for the advice. I sent him the statutory demand on 7th July by signed recorded delivery and I received notification that he received this 8th July.
What do I do now if he doesn't pay? I haven't heard anything yet and I have a copy of the paperwork I sent him as proof of the postage; would this suffice for evidence that I have issued this to him?
Sorry to ask so many questions - i'm not sure how to commence bankruptcy proceeding against him or how this will help to get my money back?
