Certain offices are incompatible with the office of representative. Members of a regional or community parliament who take the oath of office as a representative automatically cease to sit in the regional or community parliament, in accordance with the Belgian Electoral Code. The same applies the other way around as well, a representative who takes the oath of office in a regional or community parliament automatically ceases to be a representative. A member of the Chamber of Representatives may not also be a member of the Senate at the same time, and senators must give up their seats in the Senate in order to join the Chamber of Representatives.
