- Badminton serve must be hit from below the waist in underhand form (upwards)
- A serving player shall be faulted if he strikes the shuttlecock from above his waist
- In singles, the server stands in his right service court when his score is even, and in his left service court when his score is odd.
- In doubles, if the serving side wins a rally, the same player continues to serve, but he changes service courts so that he serves to each opponent in turn. When the serving side loses a rally, the serve passes to their opponents (unlike the old system, there is no "second serve"). If 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.
