@Holly1 Hi Holly, I moved to France last year, so I'm assuming the regulations will be the same, but the forms will probably be different. Assuming this is a permanent move with all your possessions, you need to have more than one copy of your inventory list. Whoever makes the first trip, ie you, or the removal van, has to have the full inventory. The removal van will have their list of what they're carrying, but you will still have to take a full inventory, including what they're carrying. I had 2 copies in English and 2 in French. Check what the requirements are for Bulgaria. Don't forget to include your vehicle, if you're taking it with you, pets must also be included.
It took me a year to pack and do my inventory, purely because no one had any idea what they were doing and I was terrified of getting it wrong and having my stuff taken off me, or being turned away.
Each item on the list has to show a simple description and value. I had to do my values in euros. You will need to check, as yours might be Leva. If its a box, then just list it as a box of ornaments, or kitchen utensils, or just a bulk category for whatever is in it. It's highly unlikely anything will be checked, having said that, I made 2 trips in my van and on the first trip a guy was having his car stripped by customs, so just be prepared. On the first trip, they checked the chips on my cats and made sure my cerfa form was in order and stamped it. On the 2nd trip I showed them the previously stamped cerfa form and the form for the second trip and they couldn't have cared less. I had the dogs in the van and I asked if they wanted to scan them and he just waved me off and shook his head. One thing they didn't do was to stamp each sheet of my inventory list. They kept one English copy, but because they hadn't stamped every sheet of my list, I was very nearly charged import duty on my van. I had to go to the Duane office over an hour away from my house, to explain why the pages of my list hadn't been stamped.
The removal company told me to keep their list under 800 euros, which was impossible and turned out to be unnecessary. I did down value most things ie if its worth £200 second hand, I'd value it at 50 euros. You're supposed to pack electrical items separate to everything else, and have receipts, or if you don't have receipts, I took a picture and of a similar item off e bay. I didn't pack mine separately, because I didn't find that out until I already packed them. No one checked, or asked for receipts.
I found out afterwards that I was allowed a total value of 15k euros, including my van and trailer. Because I'd down valued everything, my total came to about 5.5k euros.
I suppose it's a case of who you get on the day. If you get a jobsworth, they can make life difficult. I felt afterwards that I'd gone completely overboard and put far too much detail on my list and on my boxes, but because it was so difficult to get accurate information, I just wanted to cover all the bases.
If I've missed anything, or you want to ask questions, just pm me.
Sorry for War and Peace.
