Prelim notice clocks by claimant role (credit-desk checklist)

Preliminary notice is the early warning many states require before a later mechanics lien will stick. For credit teams, "early" means different day counts for owners, GCs, subs, and material suppliers. The trigger date is rarely the invoice date your ERP prefers.

For suppliers, the clock often starts when materials are first delivered or when the claimant first furnishes. For subs, it may run from starting work or from a contract date. Miss the window and you can still invoice, but the lien path may be gone. That is a credit decision, not only a legal one. A soft AR balance with a dead notice right is a different risk profile than the same balance with a live path to lien or bond claim.

1. Identify the claimant role on the job (direct contractor vs remote claimant).
2. Confirm the state notice name (preliminary notice, notice to owner, and similar labels).
3. Find the statutory start event and the day count (calendar vs business days).
4. Log who must receive it and how (certified mail, electronic service, county recorder).
5. File proof in the credit folder before the next pay app cycle.

Florida notice-to-owner timing is a common example of how state-specific this gets. See a plain walkthrough at Florida notice to owner deadline. For a broader map, keep the preliminary notice deadline guide nearby.

When you are juggling multiple states in one week, run the job through a deadline calculator instead of a single national spreadsheet tab. Wrong start date in, wrong comfort level out. Have new analysts write the trigger event in plain words next to the calculated date so the next person can audit the assumption.
