Members must provide a daytime phone number where challenges can be arranged. Former members who fail to renew by April 15 are re-instated upon payment of dues and two reservation fees, with the penalty of being positioned five places below their previous year's standing. A ladder match consists of the best two out of three sets, governed by USTA rules. Any other tie-breaking scheme may be used which is mutually agreeable. Challenge matches are normally played on the GTC clay courts, but the GTC asphalt courts or non-GTC courts may be used if mutually agreeable.
Challenge matches are umpired if either player requires it.
Players may be separated by more than ten rungs by the time the match is completed if the additional separation is due to ladder activity between the time of challenge and the time of completion. A player may make only one outstanding challenge, and may only be obligated to two outstanding challenges at any one time. After a challenge match, write the date, scores, players' names and ladder positions at the start of the match on one of the match-record cards in the box at courtside. Explain any match between players separated by more than ten rungs. Leave the card in the box for the ladder chairman to pick up.
