When Is a Ball Lost or Out of Bounds?
Part of our rules programs. Build a program with it
Rule 18.2 explains both. Your ball is lost if it isn't found within three minutes of starting to search. If you find a ball in time but aren't sure it's yours, you get a little extra time to check. For out of bounds, the entire ball has to be beyond the boundary edge. If any part is on or above the course side, it's in. Your feet can be outside the boundary while you play a ball that's inside. Either way, add a stroke and replay from where you last hit.
Step by step
- Search for three minutes.
- Identify a found ball quickly.
- Out means the whole ball is outside.
- Your stance may be outside the line.
- Add a stroke and replay.
Why it works
The three-minute limit and the whole-ball boundary test give every player the same fixed standard, so play does not stall and no one argues over a ball's position. The boundary is a line, and the line itself counts as in bounds, so a ball only has to touch the course side to be playable. Stroke and distance means you add one penalty stroke and replay from where you last hit, so a ball you cannot play costs you both the stroke and the distance.
Common mistakes
- You keep searching past three minutes because you think the ball is close.Start a timer on your phone or watch when you begin the search and stop looking when it ends.
- You call a ball out of bounds because it is near the boundary line or stake.Look straight down from above the ball and check whether any part is on or over the course side of the edge, because then it is in bounds.
- You think you cannot play a ball that is in bounds because your feet would stand outside the boundary.Play it as normal, because only the ball position decides whether it is in or out, and your stance may be outside the line.
How you'll know it's working
- You can state the three-minute limit and the whole-ball test without looking at the rule.
- You start a timer every time you search and stop when it ends.
- You add one stroke and replay from the previous spot without hesitation when a ball is lost or out.
Make it easier or harder
Easier: Practice with a single ball on a flat lawn and a rope or hose as the boundary, and move the ball to different positions along the line.
Harder: Play a round where you must announce a provisional ball before you leave the tee whenever a shot might be lost or out of bounds, and count your strokes correctly afterward.
Common questions
How long do you have to look for a lost golf ball?
You have three minutes from when you start searching. If you find a ball in that time but are unsure it is yours, you get a little extra time to identify it.
Is a golf ball out of bounds if it touches the line?
No. The entire ball must be beyond the boundary edge to be out. If any part of it is on or above the course side, the ball is in bounds.
