When there is no referee at your game, the team officials for both teams should agree on a volunteer referee for the match. This volunteer referee then adopts the responsibilities and authority of a regular referee.
After the game, the volunteer referees are entitled to the regular payment, but must complete the following form to receive their payment via cheque: Volunteer Referee Form
It would be greatly appreciated if you helped circulate the form to your game's volunteer referee should your game have one.
