I want to deregister from the association

Answer: Nooooo, that's very unfortunate. What you can do is first of all think about whether you are really sure that you no longer want to be a member of Plankenkoorts.

Are you sure? Then you should email to secretaris@plankenkoorts.com. Please note that you must deregister before September 1 of the current association year. After this, the secretary cannot do anything for you anymore, so you will be a member for another year and you must also pay contribution for that year.
