UK - Spain .. shipping of personal items
 

Hello,

I moved to Spain from the UK couple of months ago. I still have some of my personal belongings in the UK and I would like to transport it to Spain .
I would like to do it privately by road. Do you know what paperwork is necessary to avoid custom duty? Also, is there any difference in required paperwork if I drive through France to Spain rather then taking ferry from the UK to Spain?

Thank you very much for your time,

Kat
