RCW 48.50.040: Notification by insurer.

(1) When an insurer has reason to believe that a fire loss reported to the insurer may be of other than accidental cause, the insurer shall notify the insurance commissioner, in the manner prescribed under RCW 48.05.320 concerning the circumstances of the fire loss, including any and all relevant material developed from the insurer's inquiry into the fire loss.

(2) Notification of the insurance commissioner under subsection (1) of this section does not relieve the insurer of the duty to respond to a request for information from any other authorized agency and does not bar an insurer from other reporting under RCW 48.50.030(2).
