Maintenance Fees are due every December 15 of the year prior to usage. For example, the 2011 maintenance fee has to be paid by December 15, 2010. All payments received after the due date are subject to a late fee of 25%. The amounts for Maintenance Fees are posted on the website. If the maintenance fee has been paid, the owner should be able to present a receipt of payment. Otherwise, owner can be asked to fill out the Owner's Authorization to release information to third party form.
