## Checking plan

**Lawyer-led judgement**

Section 19 makes the respondent liable for the claimed amount if no payment schedule is provided in time. The statutory day is 10 business days after service, or 20 business days after service only where section 19(3)(a) applies, and that case uses the later of the contract period and the statutory day.

- What the AI does: Extract the reference date, the date of service, the contract payment period, and whether the respondent is described as an owner or a building practitioner into a date list.
- What the lawyer does: Decide whether section 19(3)(a) applies to this respondent, then calculate the due date and the schedule date from the in-force Act. Do not adopt a day count that the Act does not use.
- Who reviews: Lawyer competent in the matter and the forum
- Basis: Security of payment research on 22 September 2026. Confirm the instrument is still the in-force version.
- Why: The traffic light follows the consequence of missing a statutory payment or adjudication time.
- Restriction: The lawyer leads this decision. Assistance stays inside the preparation described for the task.

## Checks the lawyer makes

1. Open the in-force Act at sections 4A, 15, 17 and 19, and the CBOS page on making a claim. Use the Act where the page uses a different count.
2. Use one payment claim for each reference date. Serve it only within the later of the contract period and 12 months after the work was last carried out or the related goods and services were last supplied.
3. If the contract sets no due date, the progress payment is due before the expiry of the applicable day in section 19(3): 20 business days after service only for a residential structure to be built, where the respondent is the owner and is not a building practitioner; otherwise 10 business days after service.
4. Set the payment-schedule date at the earlier of the contract payment period and that applicable day, or the later of those periods in a section 19(3)(a) case. Exclude from the business-day count a Saturday, a Sunday, a day named in the Statutory Holidays Act 2000, and 27 to 31 December.

## Practical guide

Jurisdiction: Tasmania

**Deliverable**: A date list showing the reference date, the last day for serving the claim, the due date under section 15, and the payment-schedule date under section 19, with a note of whether section 19(3)(a) applies.

**Inputs**

- The payment claim and the date it was served
- The contract reference date and payment period
- Whether the claim is for a residential structure to be built, and whether the respondent is the owner and a building practitioner
- The in-force Tasmanian Act and the CBOS page on making a claim

**Example**: A commercial respondent with no contractual due date must be given a payment schedule before the expiry of the day 10 business days after service. The same day is the due date under section 15(2). A contract that requires payment sooner brings the schedule forward, because section 19(2) then takes the earlier period. The 20 business day day is used only for the section 19(3)(a) owner.

**Stop and escalate when**

- The 20 business day day has been used for a respondent who is a building practitioner, or for a claim that is not for a residential structure to be built on land.
- The schedule date has been taken from the CBOS making-a-claim page rather than from section 19.
- 27, 28, 29, 30 or 31 December has been counted as a business day.
- The schedule date and the due date have been treated as the same day where the contract sets its own time for payment.
