Not surprisingly, the Liar-in-Chief doesn't follow any rules. Here's an article from the Washington Post:

Most tellingly is the story by Sports Illustrated's Rick Reilly:
Golf is like bicycle shorts: It can reveal a lot about a guy, said Rick Reilly, the sportswriter who hit the links with Trump for his 2004 book Whos Your Caddy? in which Reilly lugged clubs for several of the worlds best golfers and VIP amateurs.
As for Trump? When it comes to cheating, hes an 11 on a scale of one to 10, Reilly said.
Reilly told The Washington Post about an afternoon when Trump wrote down scores he didnt actually achieve on his scorecard, conceded putts to himself by raking the ball into the hole with his putter rather than striking it properly (He rakes like my gardener!), and even called a gimme something a player might claim for a two-foot putt on what should have been a chip shot.
He took the worlds first gimme chip-in, Reilly said. At one point, Trump, after taking a number of second shots, told Reilly to make sure you write that I play my first ball. You dont get a second ball in life. In life, it may or may not be true that a person gets a second chance; and yet, as Reilly wrote, on holes 1, 13 and 17, Trump did indeed get a second ball.
If he cheats, his score doesn't mean a thing.
Donald Trump is an idiot.
