What Is LBW in Cricket? Leg Before Wicket Explained

LBW means Leg Before Wicket: the batter is out when the ball hits their body, almost always the pad, and would have gone on to hit the stumps. Three conditions must all hold — the ball must not have pitched outside leg stump, it must strike in line with the stumps unless no shot was offered, and ball-tracking must show it hitting the wicket. It is Law 36 of the game.

Few dismissals cause as much argument. LBW asks the umpire to judge not just what happened, but what would have happened if the pad hadn’t been in the way. That hypothetical is why it feels complicated, but the law itself follows a clear checklist.

The basic idea

A batter is out LBW when the ball hits their body, almost always the pad, and would have gone on to hit the stumps. The batter is, in effect, using their leg to stop a ball that was heading for the wicket, so the law rules them out.

The tricky part is that several conditions all have to be satisfied before the umpire can raise the finger.

The conditions umpires check

For an LBW to be given, the umpire works through these questions:

Question	Requirement
Where did the ball pitch?	In line with the stumps or on the off side — not outside leg stump
Where did it hit the batter?	In line with the stumps, unless the batter offered no shot
Was it going to hit the stumps?	Yes, the ball must be shown to be hitting the wicket

There is one important exception: if the ball strikes the pad outside the off stump but the batter made a genuine attempt to play a shot, they cannot be given out.

How DRS changed close calls

Modern cricket uses the Decision Review System to settle tight LBW appeals. Ball-tracking technology predicts the path the ball would have taken and shows whether it was hitting the stumps.

When the prediction is marginal, for example the ball just clipping the top or side of a stump, the decision falls under umpire’s call: the on-field umpire’s original ruling stands. That is why two nearly identical deliveries can produce different results depending on what the umpire first decided.

What rules out an LBW entirely

Three situations end an LBW appeal before the checklist even starts, and they account for most of the confusion around the law:

• The bat hit it first. Any contact with the bat, or the glove holding the bat, before the pad makes LBW impossible. The ball’s path is irrelevant after that. This is why the third umpire checks UltraEdge before ball-tracking.
• It was a no-ball. No-balls void LBW, so DRS checks the front foot first. A delivery that pitches in line, beats the bat, and smashes middle stump is worth nothing if the bowler overstepped.
• It pitched outside leg. No exception exists for this one, however plumb it looks.

Why the law is built this way

The conditions exist to keep the contest fair between bat and ball. Without the “pitching outside leg” protection, bowlers could aim down the leg side and trap batters cheaply. Without the “hitting in line” rule, a batter could be given out to a ball missing the stumps. Put together, the checklist makes sure LBW only rewards deliveries that were genuinely going to hit the wicket, which is exactly why it remains one of cricket’s most scrutinised decisions.
