HRS §560:2-512
Using outside events to decide who gets property
A will can leave property based on outside events that matter on their own, not just for the will. These events can happen before or after the will is signed, or before or after the person dies. Another person's will being made or canceled counts as such an event.

The statute, as written — Events of independent significance
A will may dispose of property by reference to acts and events that have significance apart from their effect upon the dispositions made by the will, whether they occur before or after the execution of the will or before or after the testator's death. The execution or revocation of another individual's will is such an event.
