Idaho Mechanic's Lien Template

Filing Deadline

Claim of lien must be recorded within 90 days after completion of labor/services or last furnishing of materials by the claimant (Idaho Code 45-507(2)).

Clock starts: Last date the claimant personally performed labor or furnished materials to the project (NOT project completion or punch-list/warranty/repair work, which typically does not extend the deadline).

Where to Record

County Recorder's office in the county where the property (or any part of it) is located (Idaho Code 45-507(2)). For Ada County (largest, Boise): Ada County Recorder, 200 W Front Street, Room 1207, Boise, ID 83702. Recording fees are typically $10 for the first page and $3 for each additional page on standard 8.5x11 format; documents must meet standard formatting requirements (1-inch margins, legible type, etc.).

Notarization

Required — document must be sworn before a notary.

Idaho Code 45-507(3) requires the claim of lien to be VERIFIED by the oath of the claimant, the claimant's agent, or attorney. This means a notarized jurat (sworn before a notary), not merely an ackno

Service Requirement

Within 5 BUSINESS DAYS after recording the claim of lien, claimant must serve a true and correct copy on the owner or reputed owner by EITHER: (a) personal service by an officer authorized by law to serve process, OR (b) certified mail to the owner's last known address (Idaho Code 45-507(5)). Failure to serve within this 5-business-day window INVALIDATES the lien. Best practice: send certified mail with return receipt requested on the same day as recording and retain the green card / USPS tracking proof.
