Ending your DIOK-membership is possible through the form below or by sending a letter. The letter needs to be delivered to the secretary (or placed inside the DIOK-mailbox). A member stays a member until a note is received on your side which states that your request has been processed. This note will be given to you by the board. When you don’t end your membership before the 1st of August of the current club year, you will automatically stay a member for the next year.
