Few things are more frustrating in golf than playing well and then being disqualified for a mistake you didn't know you'd made. Most disqualifications in club competitions come from a handful of avoidable errors. Here's what they are and how to avoid them.
This is a summary; refer to the official Rules of Golf for details.
Scorecard errors
- Lower score on a hole: disqualification. A higher score stands. Read how to fill in a golf scorecard.
- Unsigned card or marker not certifying: disqualification in stroke play.
- Forgotten penalties you didn't know about: not disqualification; the penalty is added plus an extra two strokes.
Starting times
- More than five minutes late: disqualification.
- Within five minutes late, if you're ready to play: a two-stroke penalty (or loss of the first hole in match play).
- Starting early: similar penalties.
Wrong ball and wrong place
In stroke play, if you play a wrong ball, or play from a wrong place in a way that's a serious breach, you must correct it before teeing off on the next hole (or before returning your card on the last hole). If you don't, you're disqualified. Read playing the wrong ball.
Equipment
- Making a stroke with a non-conforming club. Read conforming golf equipment.
- Making a stroke with a club whose performance you deliberately changed during the round.
- Repeated use of prohibited devices: the first breach is usually a general penalty; a second can lead to disqualification.
Practising on the course
In stroke play, practising on the course before your round on the day of the competition is generally a penalty for the first breach, and disqualification for a second. Read practising during a round: the rules.
Agreeing to ignore the rules
Players who knowingly agree to ignore a rule or penalty are disqualified.
Serious misconduct
The committee can disqualify a player for serious misconduct, such as dangerous behaviour or serious damage to the course.
How to avoid disqualification
- Arrive early and know your start time.
- Count your clubs and use conforming equipment.
- Identify your ball before every shot.
- Ask the committee when you're unsure, and play a second ball in stroke play if allowed.
- Check every hole score with your marker and sign your card.
