Any Belgian citizen who has a national number can make a euthanasia declaration.
However, Belgian consular missions can neither accept nor register the euthanasia declaration. Presently, only the Belgian municipalities can do so.
A duly completed euthanasia declaration is valid in Belgium, even if it has not been registered with a Belgian municipality.
More information on the conditions of validity of a duly completed euthanasia declaration in Belgium is available at the website of the FPS Public Health.
It is uncertain whether this type of declaration would be valid abroad.
