Do I have to pay membership fee every year even if I am not active taking part in WADF activities a specific year?

No. Your member ship is valid for one full year from the date of payment. Then your membership will turn to non-active but you remain a member.

When you decide to send dancers to a WADF competition or you are selected and accept to adjudicate or you wish to attend the WADF AGM you pay for another year of membership and your status will be updated to active for a further 12 months.
