Washington State Mechanics Lien: Guide, Process & FAQs

Under Washington state mechanics lien law, you may file a claim if you furnished labor, professional services, materials, or equipment to improve real property. Suppliers to suppliers are not eligible.

Your Claim of Lien must include the claimant’s name, phone number, and address; the first and last dates labor and/or materials were furnished; the name of the hiring party (person indebted); a property description (legal recommended); the name of the property owner; the lien amount (principal only); and your signature with notarization.

File your claim at the county auditor’s office where the property is located. If the property spans two counties, record with both. You can file in person, by mail, or electronically. Available methods vary by county. For county-specific contact info, fees, and accepted payment methods, download our free resource.

After recording, you must deliver a copy of the lien to the property owner within 14 days in person or by certified/registered mail. Missing this step won’t invalidate your lien, but it disqualifies you from recovering legal fees if you later foreclose.

A Washington mechanics lien is effective for 8 months from the date of recording. If the owner still hasn’t paid, you can send a notice of intent to lien Washington state (Notice of Intent to Foreclose) to signal you’re ready for court. Once paid, file a release of lien Washington state to clear the property title.

Any incorrect detail can invalidate the entire claim. If you’d like a reliable lien specialist to handle this for you, file a mechanics lien with Northwest Lien.
