Faults and Lets

Understanding the difference between a fault and a let is essential for correct play and fair scoring. See serve rules for the full service requirements that a valid serve must meet.

Faults

A fault is an invalid serve. One fault does not cost a point — the server gets a second attempt. Two faults on the same point (a double fault) results in a lost point.

When a Fault Is Called

A serve is a fault when:

  1. The server infringes any part of Rule 6 (position, bounce, height, motion)
  2. The server misses the ball when attempting to hit it
  3. The ball bounces outside the receiver’s service box (lines count as good)
  4. The ball hits the server, their partner, or any object worn or carried by either
  5. The ball bounces correctly in the service box but then touches the metallic fence before the second bounce
  6. The ball bounces correctly in the service box and then exits directly through the court gate in a court where out-of-court play is not authorised (no safety zone; see out-of-court play)
  7. The ball hits the net and does not land in the correct service box
  8. The server foot-faults — their foot crosses or touches the service line or imaginary centre line before striking the ball
  9. The ball is struck above waist/hip level
  10. The ball is not bounced on the ground (within the server’s service box) before being struck

Double Fault

If the server commits a fault on both the first and second serve, it is a double fault and the receiving team wins the point.

Lets

A let means the serve must be replayed in full — neither the first nor second serve is consumed. The exact same serve attempt is repeated.

When a Let Is Called on the Serve

  1. The ball touches the net or net post and then lands correctly in the service box (as long as it does not touch the fence before the second bounce)
  2. The serve is delivered before the receiver is ready (and the receiver did not attempt to return it)

When a let occurs on the first serve, the entire point is replayed and the server retains both serves. When a let occurs on the second serve, only the second serve is replayed.

Lets During a Rally

A let may also be called during a rally (not just on the serve) if:

  • A ball from another court enters the playing area and could have affected play
  • An unexpected hazard enters the court

When a let is called during a rally, the entire point is replayed — not just the specific shot.

Net Ball in Play (Not a Let)

If the ball clips the net during a regular rally (not a serve) and lands in the opponent’s court, it is in play — the rally continues. This is not a let. See ball in play for the full rules on what keeps the ball in play. See interference for lets called due to external disturbances.
