Before Playing

• On the court, spin the racquet first to decide service and ends and then warm‐up for 10 minutes.  
• During social games, you can take some serves during the warm-up (preferred) or call for “first-in”. During tournaments, warm-up serves must be taken before the first point is played.
• Don’t confuse warming up with practice. Hit the ball to your opponent in a manner that allows an easy return.

Calling Lines

• Call the lines fairly and generously.  If you cannot obviously call the ball “out”, the ball is “in” or, to put it another way, a ball that is 1% on the line is 100% in. A player calls the shots on their side of the net. If there is doubt (e.g.: a doubles team disagrees with each other), then the call must be resolved in favour of the opponent.
• Make calls of "let" or "out" immediately.
• Don't protest or question opponent's calls, either by speech or by manner.
• Always clearly signal “out” balls even if you see them as obviously out. It may not be so obvious to your opponent and eliminates any possibility of misunderstanding. 
• Never call “good” or “in” during a rally. Say nothing unless the ball is out.

Doubles Specific Guidelines for Calling Lines

• Both you and your partner take responsibility for monitoring and reporting line calls on your own side of the court, unless your partner’s vision is compromised and the call is an obvious one.
• If you are receiving the ball from a serve, and your partner is also near to the service line, he or she is better placed than you to make a call as to whether the ball was long or not.

Behaviour

• You may move at all times, but do not wave your racquet or arms or otherwise attempt to distract your opponent.
• Be certain the receiver is ready before serving.
• Avoid arguments of any kind.
• Treat your opponent with courtesy. Accept defeat graciously.       
• Dangerous or violent racquet or ball throwing, abusive language or behavior will not be tolerated. Correct behavior should be displayed at all times. 
• Do not keep up sustained conversation or excessive volume (e.g., grunting, squealing) on the court. Avoid cell phone usage on the court. These may bother other players around you. 
• Never stall. Play with deliberation but at your normal speed. Taking more than 25 seconds between points constitutes stalling. 

Ball Control/Management

• If a ball rolls onto your court, return it as soon as is practical by directing it to one of the players so that it reaches him/her on the bounce. Do not flip it back without caring where it goes. 
• If you are in the middle of a point either, stop play, return the ball and play a “let” or return the ball as soon as the point is over. 
• Do not return a ball to an adjoining court while they are playing. Wait until they have finished the rally to return their ball or carefully return it to a safe position in a non-distracting manner. 
• If your ball rolls onto another court, wait for the other members to return it to you. IF IT IS IN A DANGEROUS POSITION, ALERT THE PLAYERS IMMEDIATELY!!!
• NEVER run onto the other court to retrieve it. Wait until play stops before asking for your ball. 
• When finished, please return the balls to the basket at the back of the court. Lost balls should be reported to staff.
• When receiving serves, don’t hit balls that are clearly out.
