You and your opponent will hit the shuttle alternately until a **'fault'** is made or the shuttle ceases to be in play.

 * Scoring and serving**

Rules of Badminton - Doubles
At the start of the game, and each time a side gains the right to serve, the service shall be delivered from the right service court. Only your opponent standing diagonally opposite of you shall return the service. Should your opponent's partner touched or hit the shuttle, it shall be a 'fault' and your side scores a point.

After the service is returned, either you or your partner may hit the shuttle from any position on your side of the net. Then either player from the opposing side may do the same, and so on, until the shuttle ceases to be in play.
 * Order of play and position on court**

If you are serving or receiving first at the start of any game, you shall serve or receive in the right service court when your side or your opponent's side scored an **even number** of points. You shall serve from or receive in the **left service court** when your side or your opponent's side has scored an odd number of points. The reverse pattern shall apply to your partner. In any game, the right to serve passes consecutively from the initial server to the initial receiver, then to that initial's receiver's partner, then to the opponent who is due to serve from the right service court, then to that player's partner, and so on. You shall not serve out of turn, receive out of turn, or receive two consecutive services in the same game, except as provided in service court errors and 'lets'.
 * Scoring and serving**

A service court error has been made when a player has served out of turn, has served from the wrong service or standing on the wrong service court while being prepared to receive the service and it has been delivered. If a service court error is discovered after the next service had been delivered, the error shall not be corrected. If a service court error is discovered before the next service is delivered, the following rules apply. If both sides committed an error, it shall be a 'let'. If one side committed the error and won the rally, it shall be a 'let'. If one side committed the error and lost the rally, the error shall not be corrected. If there is a 'let' because of a service court error, the rally is replayed with the error corrected. If a service court error is not to be corrected, play in that game shall proceed without changing the player's new service courts.
 * Service court errors**

The rules of badminton consider the following as **faults**:
 * Faults**
 * If the shuttle lands outside the boundaries of the court, passes through or under the net, fail to pass the net, touches the ceiling or side walls, touches the person or dress of a player or touches any other object or person.
 * If the initial point of contact with the shuttle is not on the striker's side of the net. (The striker may, however, follow the shuttle over the net with the racket in the course of a stroke.)
 * If a player touches the net or its supports with racket, person or dress, invades an opponent's court over the net with racket or person except as permitted.
 * If a player invades an opponent's court under the net with racket or person such that an opponent is obstructed or distracted or obstructs an opponent, that is prevents an opponent from making a legal stroke where the shuttle is followed over the net.
 * If a player deliberately distracts an opponent by any action such as shouting or making gestures.
 * If the shuttle is caught and held on the racket and then slung during the execution of a stroke.
 * If the shuttle is hit twice in succession by the same player with two strokes.
 * If the shuttle is hit by a player and the player's partner successively or touches a player's racket and continues towards the back of that player's court.
 * If a player is guilty of flagrant, repeated or persistent offences under Law of Continuous Play, Misconduct, Penalties.
 * If, on service, the shuttle is caught on the net and remains suspended on top, or, on service, after passing over the net is caught in the net.

A 'let' may be given for any unforeseen or accidental occurrence.The rules of badminton consider the following as 'lets':
 * Lets**
 * 'Let'** is called by the umpire, or by a player (if there is no umpire), to halt play.
 * If a shuttle is caught in the net and remains suspended on top or, after passing over the net, is caught in the net, it shall be a 'let' except on service.
 * If, during service, the receiver and server are both faulted at the same time, it shall be a 'let'.
 * If the server serves before the receiver is ready, it shall be a 'let'.
 * If, during play, the shuttle disintegrates and the base completely separates from the rest of the shuttle, is shall be a 'let'.
 * If a line judge is unsighted and the umpire is unable to make a decision, it shall be a 'let'.
 * A 'let' may occur following a service court error. When a 'let' occurs, the play since the last service shall not count and the player who served shall serve again, except where in situations where the Law of Service Court Errors is applicable.

A shuttle is not in play when it strikes the net and remains attached there or suspended on top. A shuttle is not in play when it strikes the net or post and starts to fall towards the surface of the court on the striker's side of the net. A shuttle is not in play when it hits the surface of the court or a 'fault' or 'let' has occurred.
