WFDF membership is a requirement for registering and competing in WFDF sanctioned championship events. Only teams from regular, organizational, and associate member organizations may register for such events.

WFDF World Ultimate Club Championship Events are:

All players on Club Team Roster must be members of the National Federation in good standing, and must meet whatever other requirements are placed on them by the National Federation.

A single player may not participate on more than one team during a single WFDF Event.

Club team names must not include any wording that could reasonably be considered as offensive or inappropriate, as determined by WFDF.

The team roster must be inspected by an official of the National Federation who represents the team before being submitted. This official must countersign the roster to indicate they have inspected it and found it to be in accordance with player eligibility rules and the definition of a club team according to that National Federation.
