Faults in Badminton Service: Every Way to Lose a Point on Your Serve
6 June 2026
A service fault is any serve that breaks a service rule — too high, feet moving or on a line, a feint, a missed shuttle, or a double action — and it gives the rally (a point) straight to the opponent. Here is the full list.
The service fault that starts the most arguments
Height calls get the headlines, but the one that actually sparks club-night rows is the balk — a deceptive hitch in the serve. The server pauses mid-action, or does a little double-shuffle of the racket head, to freeze the receiver, then serves. It looks like skill; it's a fault, because the law wants one continuous forward motion and nothing else. The argument always sounds identical: "but I served it low and in!" Doesn't matter — the deception happened before contact, which is exactly where the rule lives. If your serve has a stutter in it, sand it out before it costs you a real point.

Server faults
- Contact above 1.15 m — the whole shuttle wasn't below the line at impact.
- Racket head above the hand / not underarm — the shuttle wasn't hit base-first in an upward motion.
- Foot fault — a foot moving, lifting, or touching a line during the serve.
- Balk / feint — any deliberate deception or double motion in the serve action (a hitch to fool the receiver).
- Missing the shuttle — swinging and missing on the serve is a fault.
- Wrong service court — serving from or into the wrong court for the score. In doubles, the rules about which court to serve from and who receives are tied directly to service order and rotation rules, so a firm grip on those helps you avoid this fault entirely.
- Double hit on the serve — the shuttle must be struck cleanly once; a slung or twice-contacted serve is a fault.
Receiver faults
- Moving before the serve is struck, or standing in the wrong court, faults the receiver — and the serving side gets the point.
Example
You start your serve motion, pause to bait the receiver, then continue — that's a balk, a fault, even though the contact height was fine.
