Golf Rule: What Happens if a Player Hits Your Ball on the Green?

Question
A golfer started to address the ball to putt,  I didn't mark my ball she hit me.I got a penalty stoke she didn't.  Is that the rule.

Thanks Ricki

Answer
Hello Ricki:  If you had not BOTH grounded your putter behind the ball and taken your stance, you had not addressed the ball.  Therefore, if you didn't cause your ball to move, no matter what or who did, you would not be penalized.  The other player would also NOT be penalized.

Fairways and Greens,
