You served a payment claim. Here is every date that now runs

Serving a payment claim starts several clocks at once, and they run differently from state to state. The builder has a fixed number of business days to serve a payment schedule, payment falls due whether or not they answer, and the right to take the dispute to adjudication expires if you do not lodge in time.

The one that costs the most is the first. Where a respondent does not serve a payment schedule inside the window, they become liable for the whole amount you claimed. Enter the date you served and this lays out the rest, with the section of the Act behind each date.
