In badminton, a fault is an act or an event that ends the rally and awards a point against the player/pair that committed the fault. Faults in badminton can result in losing the point or service, which can also be referred to as a fault in badminton. The most common types of faults in badminton include:

• Service Fault: This occurs when a player is serving and the service is not executed below the waist or in an upward direction.

• Contact Fault: This happens when a player touches the shuttlecock or the net with their racket or any part of their body during a rally.

• Double Hit: This occurs when a player hits the shuttlecock twice, either on their own or with a partner.

• Over the Net Fault: This happens when a player hits the shuttlecock over the net and it fails to pass over the opponents side of the court.

• Receiver Fault: This occurs when the receiver hits the shuttlecock before it has passed the net to reach their side of the court.

• Obstructing the Opponents Shot: This happens when a player tries to hit a forceful shot at the net, and the opponent raises their racket to block it.

• Invading the Opponents Court: This happens when a player steps into the opponents court with their racket or any part of their body during a rally.

• Distracting the Opponent: This happens when a player intentionally distracts their opponent during a rally.

• Gross Misconduct: This is a serious offense that can result in disqualification from the game.

It is important for players to avoid committing these faults to prevent losing points or service during a game.
