## Reminder guidance for this contract type

### Lien rights run on a statutory clock, not the contract calendar

Mechanic’s lien rights are some of the few deadlines in a construction contract that are set by statute rather than by the parties. Each jurisdiction prescribes when a preliminary or 20-day notice must be served, who it must reach, and exactly how many days after last furnishing labor or materials a lien can be recorded. These windows are short, unforgiving, and tied to project events — first delivery, last work, notice of completion — rather than to a tidy renewal date. The practical consequence is severe: serve the notice late, or record the lien a day past the window, and the right to secure the debt against the property evaporates, leaving only an unsecured claim against whoever owes the money. Tracking each statutory step as its own dated reminder, anchored to the project trigger that starts the clock, is the difference between a secured and an unsecured position.

### Waivers and retainage are where payment quietly leaks

Two mechanisms decide whether a contractor actually gets paid the full amount. Lien waivers are exchanged at almost every progress payment, and the distinction between a conditional waiver (effective only when payment clears) and an unconditional one (effective immediately, regardless of payment) is the difference between a protected and a surrendered right — signing the wrong one before funds arrive gives away leverage for nothing. Retainage is the percentage withheld from each payment, often 5 to 10 percent, released only after substantial or final completion; because it sits untouched for months it is the single most commonly forgotten sum on a project. Tracking each waiver exchange against its payment, and the retainage release against completion, keeps both the per-payment rights and the held-back balance from slipping away unnoticed.

## Quick answers

Short answers to the questions we get most about reminder extraction.

- **Q:** How does the construction lien deadline reminder work?
  **A:** Upload your construction contract, subcontract, or supply agreement as a PDF or DOCX. We run an AI extraction on the document, find the preliminary or 20-day notice deadlines, notice-to-owner requirements, the mechanic’s lien filing window, lien-waiver exchange points, and retainage release dates, and suggest reminder dates for each. You can then start a free Contracko trial to track everything automatically with email reminders, or just note the dates yourself.

- **Q:** What will the tool find in my construction contract?
  **A:** It surfaces the preliminary notice and notice-to-owner deadlines, the mechanic’s lien filing window, the lien-waiver exchanges tied to each payment, and the retainage release date. Each item comes with the source clause from your contract so you can verify before you schedule anything.

- **Q:** Why are preliminary and lien filing deadlines so important?
  **A:** Lien rights are governed by hard statutory deadlines. A preliminary or 20-day notice often has to be served within days of first furnishing labor or materials, and the mechanic’s lien itself has to be recorded within a fixed window after the last work or completion. Miss either and the right to secure the debt against the property is usually gone for good. The tool anchors each deadline to the clause and the project trigger so the clock is visible long before it runs out.

- **Q:** How does it handle lien waivers and retainage?
  **A:** Most construction payments are exchanged against lien waivers, and conditional versus unconditional waivers carry very different risk. The tool flags each waiver exchange tied to a progress payment so you do not sign away rights before funds clear. It also extracts the retainage release date — the withheld percentage that is only paid after substantial or final completion — so that money is chased on schedule rather than forgotten.

- **Q:** What happens after the extraction?
  **A:** You’ll see a list of suggested reminders pulled from your contract, each anchored to the clause it came from. From there you can start a free Contracko trial to track them automatically with email alerts and owner assignments, or just note the dates yourself if that’s all you need.

- **Q:** What happens to my contract after I upload it?
  **A:** Your contract is transmitted over TLS encryption and processed by AI providers under terms that exclude training on your data. If you start a Contracko trial, the file moves into your private workspace and stays there.
