The Build-Out Line promotes playing the ball out from the defensive third in a less pressured setting. When the goalkeeper has control (with his/her hands) of the ball during play, the opposing team MUST move behind the Build-Out Line until the ball is released (put in play) by the goalkeeper. Once the opposing team is behind the Build-Out Line, the goalkeeper can pass, throw, or roll the ball into play (punts or drop kicks are NOT allowed). After the ball is put into play by the goalkeeper, the opposing team can cross the Build-Out Line and play resumes as normal.
Also, the opposing team MUST move behind the Build-Out Line for a goal kick restart and may only cross the Build-Out Line once the ball is in play (meaning that the ball has left the penalty area).
A goalkeeper may choose to play the ball from his or her hands before the opponent has retreated behind the Build-Out Line. As the goalkeeper has willingly decided to quickly release the ball into play No penalty has incurred as long as the opposing team was attempting to move behind the Build Out Line.
After the ball is put into play by the goalkeeper, the opposing team can cross the build out line and play resumes as normal.
The ball is in play as soon as it leaves the goalkeepers hands. If they put the ball on the ground to kick it, the ball is in play and the opposing team may cross the build out line.
If the opposing team reenters the build out area prior to the ball being put in play, the keeper will repeat the previous restart.
If a goalkeeper punts the ball, an indirect free kick should be awarded to the opposing team from the spot of the offense.
If the punt occurs within the goal area, the indirect free kick should be taken on the goal area line parallel to the goal line at the nearest point to where the infringement occurred.
If a member of the opposing team does not move outside the build out line and becomes involved in play an indirect free kick will be awarded to the attacking team.
