I've never completed a VAT68 or VAT1 before for an acquisition, now HMRC are saying I must. However the old director/owner won't co-operate with anything from now on.
1. Given he won't sign, what do I do?
2. Is this actually necessary each time?
3. When I know the answer to #1, do I need to go back and complete the forms retrospectively for all other acquisitions?
