Foot Fault

During the service motion, a server may not:

  1. Change position by walking or running. Although slight movements of the feet are allowed.
  2. Touch the baseline, or the court, with either foot.
  3. Touch the area on the other side of an imaginary extension of the sideline.
  4. Touch the imaginary extension of the center mark with either foot.

If the server commits any of these actions, a foot fault may be ruled.
