2.6 THE SERVICE
2.6.1 Service shall start with the ball resting freely on the open palm of the server’s stationary free hand.
2.6.2 The server shall then project the ball near vertically upwards without imparting spin, so that it rises at least 16cm after leaving the palm of the free hand and then falls without touching anything before being struck.
2.6.3 As the ball is falling the server shall strike it so that it touches, first his court and then, after passing over or around the net assembly, touches directly the receiver’s court; in doubles, the ball shall touch successively the right half court of server and receiver.
2.6.4 From the start of service until it is struck, the ball shall be above the level of the playing surface and behind the server’s end line, and it shall not be hidden from the receiver by the server or his doubles partner or by anything they wear or carry.
2.6.5 As soon as the ball has been projected, the server’s free arm and hand shall be removed from the space between the ball and the net.
2.6.6 It is the responsibility of the player to serve so that the umpire or the assistant umpire can be satisfied that he complies with the requirements of the Law and either may decide that a service is illegal.
18.104.22.168 If either the umpire or the assistant umpire is not sure about the legality of a service he may, on the first occasion in a match, interrupt play and warn the server, but any subsequent service by that player or his doubles partner which is not clearly legal shall be considered incorrect.

2.15.4 Thereafter, each player shall serve for 1 point in turn until the end of the game, and if the receiving player or pair makes 13 returns in a rally the receiver shall score a point.
