Insurance Cancellation Period - 45 or 30 days?

If you have been named as an additional insured on a contractor's or consultant's commercial general liability policy, remember that under Washington State law (RCW 48.18.290 (1)(a)(i)), the insurance company must provide you with 45 days cancellation notice of the policy. Some insurance companies will try to only provide 30 days cancellation notice, but you have a right to insist on 45 days notice.
