A consular declaration is an official document drawn up by an embassy or consulate. Dutch nationals abroad may need a consular declaration if they want to arrange something with Dutch or foreign government institutions.
There are various reasons why Dutch nationals abroad might require a consular declaration. They may, for instance, need to submit one to the Social Insurance Bank (SVB), a pension fund, a Dutch municipality, or the authorities in the country where they live. Bear in mind that embassies and consulates must always observe the laws of the country concerned when drawing up consular declarations.
