Many states require an owner (or, in some cases, the general contractor) to record a notice of commencement before or shortly after construction begins, identifying the property, the owner, the general contractor, and often the construction lender. The notice puts the world on record notice that improvements are underway and starts the clock on statutory deadlines that govern preliminary notices, lien filing, and lien priority.

Disputes over the notice of commencement usually involve its absence, its late recording, or inaccuracies in it (wrong legal description, omitted lender, wrong general contractor) that a lien claimant argues excuses its own missed deadline, or that an owner argues invalidates a lien filed against the wrong reference point. Because construction lien rights are purely statutory, a defective notice of commencement can shift priority in ways that matter enormously in a payment dispute.

Within Juricratic's construction-payment branch, the notice of commencement functions as a timeline anchor: the model uses its recorded date (or its absence) to compute whether downstream lien and bond claims fall inside or outside their statutory windows, rather than asking the user to separately track each deadline.

Owners and lenders record and verify the notice of commencement to start the correct statutory clock and protect priority, while lien claimants and their counsel check it to calculate preliminary notice and lien-filing deadlines and to confirm they served notice on the parties actually identified in it.
