A bit of a long story..but hoping someone can help. We had a motorhome registered in BG where we had lived for three years. Drove it back on Bulgarian plates to UK. Continued driving it for a few weeks in UK as we were going back. But our house in BG was burned down all documents etc burned in fire. We stayed in UK and rented somewhere as we had nowhere to return to..sold the motorhome as it broke down and without any document for spare parts to an old guy who was going to take the parts he needed and scrap the rest. That's that we thought 🤔 Still have a company and have been paying house taxes in BG ever since so up to date. BUT I have been tipped off by a dear friend that we owe car tax on the vehicle as we never deregistered it. I think it's about 450leva ATM so nothing too much..but question is what should I do? If the debt grows obviously I will be in trouble..I have no record of the vehicle in UK or Bulgaria I don't even remember the reg. It's just a blunder on my part which I need to tidy up for my own peace of mind. Any advice?
