Submission: A player can repair a ball mark on the green at any time. The player’s ball does not need to be on the green to allow the repair. A player cannot repair a ball mark on the fringe if it is in the player’s line of play. Unless the mark occurred after the ball came to rest.
Question: What if any one of your playing partners repairs the mark without being requested to do so? On the other hand, are you allowed to ask a playing partner to repair the mark?
Answer: I assume you are referring to players in your group of a stroke play event who are NOT your partners (the answers will be different).
Someone who is in your group but not your partner is an outside influence, and if they improve your line of play, that will get them a 2-stroke penalty, but nothing to you. Additionally, you get the benefit of the repaired pitch mark.
If that person is your partner, you will both get a penalty of 2 strokes.
If you request the player to fix it for you and he does just that, both you and he will get the 2-stroke penalty.
