First you have to have a witness and the answer is yes. If it goes in the hole in one shot it is a hole in one, unless you are playing less than nine holes, and you must not be playing more than one golf ball during the round.

Your chances of making a hole-in-one are typically not related to your skill level or how many times you play golf.

The rules specify that you should hit the ball from a standard or "recognized" tee box.

The rules also require that you hit the ball from the normal tee or a club-modified tee that is recognized by the USGA (United States Golf Association). You must play a round of at least nine holes to qualify. Rushing to your course after work at 7 p.m. and playing five holes before dark will not qualify, even though you may enjoy the thrill of a tee-to-green hole out.

Also, even if you play the minimum nine holes, but as a "practice" round (using two or three balls), you cannot score a USGA-recognized hole-in-one. You must play one ball only.

Green Rules
While you aren't required to land on the green on your tee shot, there are a couple of rules that affect the hole and pin placement. For example, should you make your hole-in-one on a "temporary" green (installed when a permanent green is undergoing rebuilding, relocated after a bout of serious and heavy rain, or sometimes used in the spring in colder climates to protect the permanent green for summer play), your hole-in-one is still valid. However, if there is a group ahead of you, they cannot hold, touch or manipulate the pin in any way.

Hope this clears this up for you and your friend. If you were playing a regular round of golf (nine or eighteen holes) then he obviously was jealous. Then I congratulate you.

Find a new playing partner. Definitely a hole in one.
