Unpaid construction work

File a mechanics lien before the recording window closes.

A lien filing is a recorded claim, separate from the preliminary notice sent at the beginning of a job. The filing office, deadline, required parties, verification, and service steps depend on the state and project.

Start with the final furnishing and completion dates

Most lien filing periods run from the claimant's last labor or material date, completion of the improvement, or a recorded notice of completion. The job file preserves those dates separately because using the contract date or invoice date can produce the wrong deadline.

Identify the filing office

Many claims are recorded with the county recorder or clerk where the property is located. Hawaii uses a circuit-court application. Delaware uses a court filing. Registry states add separate electronic steps. FirstFurnish sends the claim to the office required for the property and state.

Complete filing and service

Recording a lien does not always complete the claim. Some states require a copy served on the owner, contractor, or other parties before or after recording. Certified-mail tracking and the returned instrument remain in the same job record.

Check the filing date before preparing the claim.

Enter the state, role, project type, and job dates. No card is required to save the deadline.
