Serve

• The racket must hit the shuttle while the entire shuttle is discernibly below the server's waist.
• When the shuttle is hit, the entire head of the racket must be discernibly below the server's hand.

• Once the players have taken their positions, the first forward movement of the server's racket head shall be the start of the service.
• Some part of both feet of server and receiver must remain in contact with the floor in a stationary position until the service is delivered.
• The server's racket must hit the shuttle while the entire shuttle is below the server's waist.
• When the shuttle is hit, the entire head of the racket must below the entire server's hand.
Where to stand during a serve
• The server and receiver must stand in diagonally opposite service courts.
• Neither the receiver nor server may have their feet on or past the boundary lines of the service court.
• The receiver's partner may stand anywhere, but must not hit the serve.
• After the serve is returned, either player on a team may hit the shuttle, and players may position themselves anywhere.
• Singles: If the server has an even number of points, the serve is from the right. If the server has an odd number of points, the serve is from the left.
• Doubles: To start the game, the person in the right court has the serve. If the serving team gets the point, they rotate sides, and the same person now serves from the left. This continues until the serving team loses the rally. Then the serve passes to the other team. The person on the right always serves first. They rotate if they get a point. If they lose the rally, the serve goes to the second person on that team ("second serve"). When the rally is lost, the serve passes to the other team. Each time that the serve passes to a new team, both players get to serve until they lose a rally.
