Hi, My mom (Polish) passed away last year. I fully inherited the flat (I have a notarial act), on which I already had a half ownership after my dad passed away many years ago. There was no will left. Whenever I went back to Poland I lived with my mom for those periods of time (I have been in the UK for over 16 years now), I have my and her belongings there. I would like to go to Poland by car and bring everything over (nothing valuable, mainly memorabilia, books that mom bought be not so long before she passed - they are new, instruments used by her father, some decorations, household items, etc). Everything just for a personal use. I tried to call HMRC, different departments, and cannot get a direct answer whether I can just come and bring those goods, or whether I have to fill in any forms, pay any taxes. What do I need to prepare and how long in advance before travel? A|re you able to advise, please?
