RCW 11.95A.340: Notice of exercise of testamentary power.

Unless the person holding property subject to a testamentary power of appointment has within six months after the holder's death received written notice that the powerholder's last will has been admitted to probate or an adjudication of testacy has been entered with respect to the powerholder's last will in some jurisdiction, the person may, until the time the notice is received, transfer the property subject to appointment on the basis that the power has not been effectively exercised.
