Q: Who counts as the player's caddie under the Rules?

A caddie is someone who helps the player during a round by carrying, transporting or handling their clubs, giving advice and helping in other ways the Rules allow. A player may have only one caddie at a time. They may change caddies during the round, but not temporarily just to get advice from someone new. Someone who walks or rides along, or carries other things such as a rain suit, umbrella or food and drink, is not the caddie unless the player names them as caddie or they also carry or handle the clubs. Players who are blind, use assistive mobility devices or have intellectual disabilities may also have an aide as well as a caddie (Rule 25). The Committee may have a Local Rule that bans, requires or restricts caddies in a competition. Penalty for more than one caddie at once: two strokes for each hole where it happens (loss of hole in match play). Source: Rules of Golf (2023), Rule 10.3a.
