Will it be an lbw if the ball pitches outside the off stump?

Question

I was recently watching a cricket match where umpire gave an lbw out when the ball pitched outside the off stump. I want to confirm that in such a case is it legitimate to give an lbw out please specify.

Answer 1

Yes, If in the opinion of the umpire it could hit the stumps if there was no obstacle AND if the batsman makes no attempt to hit the ball.
