Preliminary notice deadline
The notice that preserves lien rights before any payment problem exists.
| Who | Project type | Deadline |
|---|---|---|
| General contractors | All projects | Before signing a contract over $2,000 with a homeowner or residential buyer (1 to 4 dwelling units), the general contractor must give the statutory lien disclosure statement and keep the signed acknowledgment of receipt |
Mechanics lien filing deadline
The last day the lien can be recorded against the property.
| Who | Project type | Deadline |
|---|---|---|
| All claimants | All projects | Within 90 days after last furnishing labor or materials |
Idaho does not require a notice of intent before recording a lien, but sending one is often what gets the invoice paid.
Recording and enforcing an Idaho lien
Recording the lien
Record with the county recorder where the property sits. Electronic recording is available in participating counties. The lien must be notarized. The lien claim must be sworn to under oath.
After recording
A copy of the recorded lien must be served on the property owner within 5 days of recording. To keep the lien alive it must be enforced by lawsuit within 6 months after the lien is recorded.
Wrongful lien exposure
In Idaho, a wrongful lien claimant can be ordered to pay the owner's attorney fees and costs. Chapter 5 has no section that specifically punishes a false or excessive lien, but since July 1, 2022 the prevailing party in any court proceeding about a lien filed under § 45-507 is entitled to reasonable attorney fees and costs, so an owner who defeats an invalid lien can recover fees.
Practitioner notes for Idaho
Idaho does not require subcontractors or suppliers to send a preliminary notice. The main pre-job rule is for general contractors on homes: before signing a contract over $2,000 to build, alter or repair residential property of one to four units, the contractor must give the owner a lien disclosure statement and keep the signed acknowledgment (Idaho Code § 45-525). A lien claim on that work must include proof of the disclosure (Idaho Code § 45-507(3)(e)). Failing to give it is also treated as a deceptive practice under the consumer protection act. Every claimant must record the claim of lien with the county recorder in the county where the property is located within 90 days after last furnishing labor, services or materials (Idaho Code § 45-507(1), (2)). The claim must be verified by oath, and a copy must be served on the owner personally or by certified mail no later than 5 business days after filing (Idaho Code § 45-507(4), (5)). The lien lapses unless a suit to enforce it is started within 6 months after the claim is filed. A payment on account or a written extension of credit endorsed on the lien record restarts that period (Idaho Code § 45-510). Since July 1, 2022, the winning side in any court case over the lien recovers reasonable attorney fees and costs (Idaho Code § 45-507(7)). That cuts both ways, so a claimant should be sure of the amount before filing.
