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.
