What must the marker do when the game is finished?

When the game has been completed, the marker must make sure the score card (law 42.4):

1. contains the names and signatures of the players;
2. contains the time at which the game was completed; and
3. is dealt with in line with the Conditions of Play.

The Conditions of Play are set by the Controlling Body, which is the body with immediate control over how the game is played: World Bowls, then a national authority such as Bowls Australia, then divisions within it, then the club on whose green the game is played (definition A and law 57.2).
