When you find out it’s necessary to forfeit a court, the earlier you notify your opponent the better. The night before is really the best, but sometimes things come up.
If the forfeit is known about in advance, call the other team’s captain and let her know that you will be forfeiting Court 4. If you have to forfeit two, then the next court to forfeit is Court 3.
Make sure the home team captain calls the club where you are playing as early as possible to avoid having to pay for the court time. Most clubs say they require 24 hours notice, but usually they won’t charge you if you let them know the night before.
A forfeited court goes on the score sheet as a 6-0, 6-0 win for the non-forfeiting team. They get all the games and all the points that court is worth.
If you don’t have advance notice of a forfeit (and things do come up), the forfeiting team is responsible for paying for the court time for both teams UNLESS THE PLAYERS AGREE TO PLAY for fun or otherwise.
No captain should ever have to ASK a team to forfeit. If your team is the offending team (i.e. someone is late, the strength roster is violated, etc.), then it is your responsibility to GRACIOUSLY & PROMPTLY offer a forfeit to your opponent. She is entitled to it, and players or captains should NEVER EXPECT an opponent to overlook a rules violation. The rules are written to prevent a captain from being put into an awkward situation. So if your team breaks a rule, step up and take your medicine. Your reputation is worth far more than a few points.
Having said that, if a captain offers to overlook an extenuating circumstance (like a player is delayed in traffic being delayed for a couple of minutes, etc.), then neither captain can use that violation as grounds for a grievance.
