Do you wish to transport the body of a deceased person from the Netherlands to a foreign country? To do this, you need transportation authorisation from the municipality where the person died. This is called a laissez-passer. In most cases, the funeral director submits the application for you.
If you wish to take the body of a deceased person to Belgium or Luxembourg, you do not need a laissez-passer. However, you must have written permission from the municipality, stating that that you may bury or cremate the deceased person. This is called leave for burial (verlof tot begraven) or leave for cremation (verlof tot cremeren). You submit the application for this leave at the same time as you register the death.
This is how it works for you
Here is some information from your municipality.
Municipality of Steenwijkerland: Taking a deceased person out of the Netherlands
Did the person pass away in the Netherlands? And do you want to have them transported outside the Netherlands? If so, you (or a funeral director) must register the death. You must do this in the municipality where the deceased person is registered. To do so, you must make an appointment with the municipality.
