I have no clue on the legal process for the UK as I didn’t get any “divorce bill” from the country in which I’m no longer a tax paying resident at. As far as I’m aware, only the US will chase you down to the end of the world for unpaid taxes. All I had to do was inform them (the eu country) that I’m leaving and will no longer be spending an excess of 180 days within, which is the right course of action. I get my VAT back when I fly out of the EU 😎
