Thanks for your reply.
1. Shares were sold in 06/07 and 07/08
2. £100k lent in 2007
3. Company not liquidated, it was being struck off the register but HMRC disputed due to outstanding PAYE and NIC and currently in limbo
4. Loan was not converted into shares
Hope this helps
Yes, the company is no longer trading following an expensive but failed cash-raise but has not been wound up. I was a director and held 55% of the shares. It has no assets.
