Moving to UK, husband staying back
My company has given me an excellente offer (permanent UK job contract) to move to the UK but my husband loves his job here too and would like to stay back in Antwerpen Belgie. We agreed for me to make the move for atleast 1 year to max 2 years and he will stay back here since we own a house. My company will do the necessary formalities needed after Brexit for me stay back there after 3/2019. The fact that we are both Belgians citizens and we own the house, what would I need to do here to exit the Belgische systeme properly (mostly related to taxes, house deed, other legal formalities)?
