In Washington, we are required to file our lien within 90 days after our last day on the job. Typically, invoices are partially paid within 30 days by the insurance company (undisputed amount) and the remaining discrepancy will be the basis for our Notice of Intent to Lien. My question is, at what point during the 90 days should we be sending a notice of intent to lien to try and spur payment by either the insured or the insurance company? Preferably we would like to be paid by the insurance company to avoid negative reviews from the customer. Thanks Z
