Introduction to service faults

The service fault is the most common type of fault in badminton. Because each player’s serve action is slightly different, it isn’t easy to judge whether their serve action is against the rules. This is why, in international tournaments, as well as an umpire and six line judges, there is a service judge directly opposite the umpire.

The main duty of the service judge is to focus on whether a player’s serve action breaches the rules. The presence of a service judge effectively reduces the number of service disputes, however, most people don’t have a service judge when playing in the local sports hall so, in this situation, how can it be judged if you or your opponent has broken the service rules? Below, some common service faults will be introduced.

Commonly seen service faults

1.	Serving before the opponent is ready.
2.	The racket handle faces up when the shuttlecock is hit.
3.	Two-stage service action (not a continuous single action).
4.	When it is hit, the shuttlecock is higher than the waist of the server (an imaginary line under the bottom rib of the server).

Aside from the aforementioned faults, if players encounter other serve actions they suspect are against the rules, we suggest you refer to the contents of Item 9 in the Laws of Badminton announced by the BWF to clarify if an action should be ruled a fault or not.
