Introduction

The full text of Rule 25 can be found in the Rules of Golf.

A number of players have physical limitations that may result in some degree of disability and that may affect their ability to play the game. Rule 25 allows a player with a disability to compete fairly with players who have no disabilities, the same disability or different disabilities. 

For the most part, the modifications covered in Rule 25 are such that there is no allowance for modification to clubs, balls, devices or other equipment. However, there are some cases where a modification is required.

There are two cases where a modification to a club or other equipment could be allowed without consultation with the R&A or USGA, but only if the Committee is of the opinion that it is warranted and does not provide the player with an undue advantage.
