When is a ball considered lost?

A ball is lost when it cannot be found within the 3-minute search time, counted from the moment the player (or their caddie or companions) begins searching for it in the area where it is believed to be.

If the ball is found within 3 minutes but cannot be identified as the player's ball, it is also considered lost.

The 3 minutes: how they are counted

The time starts when the player or their caddie arrives at the search area, not from when the stroke was played. If you wait for another player to hit before going to search for your ball, that waiting time doesn't count against you.

In practice: if you take 2 minutes to reach the area and find the ball at 2:45, you're within the allowed time. If you arrive at the area and search for 3 minutes without finding it, it's lost — even if only 5 total minutes have passed since the stroke.

Consequence: stroke and distance

When a ball is lost or out of bounds, the only option under the standard Rules is stroke and distance:

Return to the exact point from which the previous stroke was played
Play from there with a 1-stroke penalty

If you played from the tee and the ball is lost: your next shot is your 3rd from the tee.

The provisional ball: how to avoid the walk of shame

Whenever there is a chance your ball may be lost or out of bounds (but not in a penalty area), you can play a provisional ball before going to search for it.

How to declare it correctly:

Clearly announce to your companions: "I'm going to play a provisional ball"
Play from the same point as the original (or as close as possible if on the tee)
Go search for the original — you have 3 minutes
If you find the original ball in bounds and in play → you must play the original, abandoning the provisional without penalty
If you don't find it within 3 minutes → the provisional becomes your ball in play with a 1-stroke penalty

Important: if you don't declare the provisional as such before playing it, any additional ball you play automatically becomes the ball in play with stroke and distance, and the original can no longer be searched for.

Local rule Model E-5: the drop-near-OB option

Many clubs use Local Rule E-5, which allows players, instead of returning to the original point, to drop near where the ball is estimated to have crossed the boundary or been lost, with a 2-stroke penalty. This only applies if the club has activated it.

Ball lost in a penalty area

If your ball lands in a penalty area (water, red-staked or yellow-staked zone), the lost ball rule doesn't apply — the penalty area relief options apply instead (Rule 17.1). In this case you don't need to search for 3 minutes: you can apply relief directly if it's reasonably certain the ball is in the penalty area.

Penalty

1 stroke (stroke and distance, standard rule). With Local Rule E-5 active: 2 strokes (drop at the estimated entry point).

Tactical advice

If there's any doubt your ball might be lost, play the provisional immediately. The most costly mistake in amateur golf is going to find the ball, seeing it's missing, and having to walk back to the tee. It costs 5 minutes and an avoidable penalty stroke.
