If a player inadvertently exposes the wrong tiles or exposes too many jokers, they can add to or take away from the current exposure as long as they have not discarded. After a player has discarded, exposures on their rack cannot be changed.

It is every player’s responsibility to verify they’ve made a correct exposure.
Several situations can make a hand invalid or no longer viable (i.e., dead), too many or too few tiles, picking from the wrong end of the wall, an invalid combination of exposures (including those from a concealed hand).
A player should not call their hand dead, even if their hand is no longer viable.
If a player has been declared dead and notices another player’s hand is dead, they cannot call that player’s hand dead.
Jokers exposed before a hand is declared dead are still available for a Joker exchange.
If a player claims a discard for mah jongg and the player’s mah jongg was in error, the claimed discard remains with that player’s dead hand and cannot be reclaimed or called by another player.
If a player picks a tile from the wall, declares mah jongg, and starts to expose his tiles only to find out he did not have mah jongg, their hand would be considered dead.
