A penalty-kick shall be taken form the penalty mark, and when it is being taken, all players with the exception of the player taking the kick, properly identified, and the opposing goalkeeper, shall be within the field of play but outside the penalty area, at least ten yards from the penalty mark and must stand behind the penalty mark.
The opposing goalkeeper must stand (without moving his feet) on his own goal line, between the goal posts, until the ball is kicked. The player taking the kick must kick the ball forward; he shall not play the ball a second until it has been touched or played by another player. The ball shall be deemed in play directly it is kicked, i.e. when it has traveled the distance of its own circumference. A goal may be scored directly from a penalty-kick. When a penalty-kick is being taken during the normal course of play, or when time has been extended at half-time or full-time to allow a penalty-kick to be taken or retaken, a goal shall not be nullified if, before passing between the posts and under the crossbar, the ball touches either or both of the goalposts , or the crossbar, or the goalkeeper, or any combination of these agencies, providing that no other infringement has occurred.
For any infringement of this Law:
a) by the defending team, the kick shall be retaken if a goal has not resulted;
b) by the attacking team, other than by the player taking the kick, if a goal is scored it shall be disallowed and the kick retaken;
c) by a player taking the penalty-kick, committed after the ball is in play, a player of the opposing team shall take an indirect free-kick from the spot where the infringement occurred, subject to the overriding conditions imposed in Law 13.
