Rule 801.7a

If a trigger event includes an object moving out of or into a player's range of influence, use the game state before or after the event as appropriate to determine whether the triggered ability will trigger. See rule 603.6. Example: Carissa and Alex are outside each other's range of influence. Carissa controls a creature owned by Alex and they each control a Soul Net, an artifact which reads, "Whenever a creature is put into a graveyard from the battlefield, you may pay {1}. If you do, you gain 1 life." The creature is destroyed and is put into Alex's graveyard. Alex's Soul Net doesn't trigger because the destruction event was outside Alex's range of influence. Carissa's Soul Net does trigger, even though the creature is going to a graveyard outside her range, because the destruction event was within her range.
