When should I ask the square leg umpire for help?

Question

Accepted Answer

Ask whenever they had a better view than you. That's usually:

run outs at the striker's end (these are their call)
hit wicket
catches near square leg or taken close to the ground
whether a batter grounded their bat before turning at the striker's end ("one short")
too many fielders behind square leg, or a fielder within 15 metres of the striker.

Agree a quick way to check with each other before the game, such as a hand on the chest for "not out". At two balls remaining in each over, hold up two fingers to confirm the count with them.
