I'm not too up on the different types of business model, but as far as I know, if you've resigned as director (and hold no other similar post, like secretary) then I don't think you can be held liable. If your shares have been re-allocated, then I'd guess all the paperwork to confirm your resignation has gone through to Companies House fine and you're no longer part of the company (or at least not in a role where you'd bear financial responsibility). At any rate, if you were a director, then liabilities incurred by the business shouldn't really affect you personally. That's my initial take on it anyway.. hopefully others can agree, disagree or clarify more
