Inheritance tax is a regional competence and therefore potentially follows different rules according to whether the deceased was registered in Flanders, Brussels or Wallonia. Certainly the current Flemish rules are very different to the old rules, and to the current rules in Brussels and Wallonia.

In Belgium, you should speak to your notaire. As for "Trusts", your best bet is probably to speak with the trustees, or the solicitor who set it up.
