One of the nice things about the changes to the rules of golf in 2019 is that they have given more leeway to the committee at your club to make decisions, such as deciding which Local Rules they would like to adopt.
The USGA defines local rules as: “a modification of a Rule or an additional Rule that the Committee adopts for general play or a particular competition.”
The Committee is responsible for deciding whether to adopt any Local Rules and for making sure they are consistent with the principles of the rules of golf.
The USGA goes on to say “The Committee needs to make sure that any Local Rules are available for players to see, whether on the scorecard, a separate handout, a notice board or the course’s website.”
