The player on the right always serves first. The ball must contact the paddle below the waist using an underhand motion and must land in the diagonally opposite court, beyond the non-volley line. The server must start with both feet behind the baseline during the serve with at least one foot on the court surface at the time the ball is struck and hit the ball without bouncing it first. Both players on a team will serve before the service passes to the other team.
When the serving team wins a point, the server moves to the other side of the serving team's court. This first servers continues to alternate sides and continues to serve until the team loses a rally. In doubles, one team member will serve and continue to serve until the team loses the rally. Then the other team member serves until he/she loses their serve. Then the serves goes over to the other team.
From this point on each player from both teams will serve before losing the serve to the other side. To keep the first service of a game fair, only the first player serves during the first service of the game.
