The payment clock

Four steps, each with a statutory date attached. The first runs from the day you mobilise; the rest run from the day you finish. They are not the same date, and nobody sends a reminder.

  1. 01

    Preliminary notice

    20-45 days from first work

  2. 02

    Notice of intent

    when payment stalls

  3. 03

    Record the lien

    30 days to 4+ months, by state

  4. 04

    Suit to enforce

    90 days to a year+, by state

The exact windows are set state by state: see mechanics lien deadlines by state. On public work there is no lien to record at all, and a bond claim takes its place; the lien vs payment bond comparison explains which one your job has.
