Rob - I'm not taking the high moral ground on this either, but the thread wouldn't exist if it there wasn't some doubt in the mind of the OP. The system has some built in potential to catch him out so he can either take his chances that they don't ask for all the paperwork they could or proceed in a way that recognizes the risks and that trying to lay a false paper or crumb trail is a bit iffy legally. If you mess with the Revenue and they take aim at you it often doesn't end well.
