Basic Rules and Regulations

When the server serves, the shuttlecock must pass over the short service line on the opponents' court or it will count as a fault.

In singles, the server stands in their right service court when their score is even, and in her/his left service court when her/his score is odd.

In doubles, if the serving side wins a rally, the same player continues to serve, but he/she changes service courts so that she/he serves to a different opponent each time. If the opponents win the rally and their new score is even, the player in the right service court serves; if odd, the player in the left service court serves. The players' service courts are determined by their positions at the start of the previous rally, not by where they were standing at the end of the rally. A consequence of this system is that, each time a side regains the service, the server will be the player who did not serve last time.
