ACT: Respondent Prepares Payment Schedule

Start Menu

A payment schedule need only be prepared if the respondent does not intend to pay the full amount of a payment claim by the due date for payment.


Who is a Respondent?

A respondent is a person who has received a payment claim under the Act.

Important qualification: If a contract includes work other than on the respondent’s residence, then that work is subject to the Act. The Act applies to contracts involving residential investment properties, landlords, strata title bodies corporate, developers, builders, contractors, sub-contractors, consultants and suppliers. The definition of resident-owner under section 9(7) of the Act does not include a person who is or should be licenced as an owner-builder under the Construction Occupations (Licensing) Act 2004. Therefore an owner-builder qualifies as a respondent and may be served with a payment claim.

What is a payment schedule?

A payment schedule is the notice in writing which must be served on the claimant if the respondent does not intend to pay the full amount of a payment claim by the due date for payment. This is regardless of the respondent believing that the claimant is or is not entitled to make the claim or if the respondent denies being a party to the contract. Assuming a payment claim is not valid, and therefore can be ignored, is risky. Click here for details about a payment claim.

What is the due date for payment?

A claimant is entitled to be paid a valid progress payment claim by the due date for payment.

The due date for payment under the Act is the earlier of 15 business days** after a payment claim is given, or the day when the payment becomes payable under the contract. If the contract provides that payment is due 10 days after invoice then, upon service of the payment claim, the due date for payment under the Act is 10 days later. Proper calculation of this date is imperative as a number of milestones under the Act are calculated from this date.

Time frames:

The payment schedule is due within 10 business days after receipt of the payment claim, or a shorter period if provided by the contract. A contract provision seeking to extend the period for the provision of a payment schedule beyond 10 business days is void.

A payment schedule must:

  • Be in writing and addressed to the claimant;
  • Identify the payment claim to which it relates;
  • State the scheduled amount of payment that it is proposed to be paid (it may be "nil");
  • If the amount that the respondent proposes to pay is less than the amount claimed in the payment claim, the respondent should set out:
    • The amount (if any) that the respondent agrees to pay - the "scheduled amount";
    • The amount that the respondent does not agree to pay under the payment claim;
    • Detailed reasons in the attachment(s) as to why the respondent intends withholding any amount, including how the valuation of the withheld amount is calculated.

Where available, payment schedules should include attachments such as:

  • statements detailing the extent of the work completed;
  • completion certificates;
  • delivery dockets;
  • photographs;
  • other contract documentation as may be required by contract.

What contract provisions are void by the Act?

A common reason for respondents not agreeing to a payment claim is that they have not been paid by the principal. Effectively the respondent is imposing on the claimant an extension of payment terms. This defence of "pay when paid" or "pay if paid" is expressly barred by the Act, even if such right is included in the contract. The policy behind the Act is that a respondent should not cause a claimant financial detriment because of their problems. In any case, respondents can seek a remedy under the Act by serving a payment claim on the principal and applying for adjudication

Other void contract provisions include:

  • Any provisions that are inconsistent with the Act;
  • Clauses that attempt to "contract out" of the Act;
  • "Pay if paid" and "pay when paid" clauses, even if they are included in the contract;
  • Clauses aimed to deter a person from taking action under the Act; and
  • Any provision which limits interest on late progress payments at a rate less than the rate of interest on judgments of the Supreme Court.

How is a Payment Schedule served?

Service should occur during normal business hours, at the claimant's ordinary place of business or as otherwise required by the contract. In the absence of a contrary contract provision, the safest way of ensuring service is to serve by courier with instruction to obtain a signed receipt. In our experience, below is the safest ranking to ensure service:

  1. Courier - signature required
  2. Mail - Express Post: keep express post tracking number for delivery verification
  3. Platinum Post - Signature required
  4. Ordinary Post - Make a statement verifying the address, date of postage and other relevant details
  5. Fax - Print and keep full page fax journal report as evidence of transmittal. Do not use fax for colour photographs and plans as they are generally rendered unreadable. Lengthy faxes have been known to lose pages in transmission.
  6. Email (only to an email address which is specified by the person for the services of notices of that kind - generally the respondent). In email options, we advise tick both "request a delivery receipt" and "request a read receipt"
  7. In person - Ensure a receipt is obtained or
  8. A different method only where such method is provided under the relevant construction contract.


  • Respondents are strongly advised to keep a record of the time, date and manner of service on the claimant. A claimant may deny receiving a payment schedule in which case the respondent must be able to evidence the date of service.
  • When items are sent by ordinary post, allow sufficient time for them to be received. Generally, items sent by ordinary post are deemed to be received on the fourth working day after posting. We recommend against post as claimants have denied receipt.

What happens if the payment schedule is not served within time?

A payment schedule should be served on the claimant within 10 business days of the payment claim or shorter period if provided by the construction contract. A respondent who fails to comply must be given a second opportunity to provide a payment schedule. If the respondent ignores the second opportunity, the Act denies the respondent the right to participate in the adjudication process. The respondent is being punished for failure to comply with the Act.

The requirement on the claimant to provide a second opportunity to the respondent that did not provide a payment schedule within time results in different time frames and procedures under the Act:

  • Procedure 1 - Respondent serves a valid payment schedule within 10 business days after receipt of the claimant's payment claim

A valid payment schedule has been served when a claimant provides a payment claim to a respondent and the respondent provides the claimant with a payment schedule within 10 business days of receipt of the payment claim. (Note: Service by the respondent of a payment schedule after 10 business days renders the payment schedule invalid - go to procedure 2).

The claimant seeks adjudication because either there is a dispute over the respondent's reasons for withholding some or all of the claimed amount; or the claimant has accepted the payment schedule but the respondent fails to pay the scheduled amount by the due date of payment. The blue shaded section of the flowchart describes how to proceed in these circumstances.

  • Procedure 2 - Respondent does NOT serve a valid payment schedule within 10 business days after receipt of the claimant's payment claim

When a respondent fails to serve a valid payment schedule within 10 business days after receipt of the claimant's payment claim, the Act requires that the claimant sends the respondent a notice under section 19(2). The effect of this notice is to provide the respondent with a second opportunity to serve the claimant with a payment schedule; however within the shorter period of 5 business days. Once the claimant serves the section 19(2) notice, there are two mutually exclusive possibilities.

Either the respondent:

  • serves; or
  • does not serve

a valid payment schedule within 5 business days after receipt of the section 19(2) notice.

The pink shaded section of the flowchart describes both the procedures and time frames of serving the section 19(2) notice and how to proceed to adjudication if the respondent again fails to issue a payment schedule or, if the respondent does serve and the claimant does not agree with the payment schedule or, the respondent fails to pay a scheduled amount.

Parties must comply with the statutory procedures and time frames of the Act. Failure to comply may have serious consequences. Some examples of common errors which can't be corrected by either Adjudicate Today or the adjudicator:

  • The respondent provides the payment schedule after 10 business days (e.g. business day 16). As it is invalid, the claimant must serve the section 19(2) notice and the respondent must provide (again) the payment schedule (within 5 business days  of receipt of the section 19(2) notice).
  • The claimant prepares and serves the adjudication application after 10 business days (e.g. business day 16) of receipt of a valid payment schedule. As the statutory time has passed, the payment claim has expired and the adjudicator must determine that the application is invalid.
  • The claimant prepares and serves an adjudication application on Adjudicate Today and/or the respondent prior to the expiry of the 5 business days permitted to a respondent to provide a payment schedule under section 19(2). The application is invalid as it has been served early. The claimant should have waited for the fifth business day to elapse. The application may be served again after the fifth business day from the respondent's receipt of the section 19(2) notice but before the tenth business day expires.

The lesson from each of these examples is to count business days carefully, remembering that the first business day is the first day after service (excluding Saturday, Sunday, public holidays or bank holidays and; all days between Christmas and New Year) i.e. the first business day of service is day 0.

Avoid pitfalls

At the request of parties we have prepared a list of common reasons that respondents fail to succeed in adjudication.

Please move to the next step on the ACT flowchart by selecting either "Respondent serves a Payment Schedule within time" or "Respondent FAILS to serve a Payment Schedule within time" depending on the circumstances.

**We note that the ACT Government has advised that the “the changes to the Building and Construction Industry (Security of Payment) Act 2009, which commenced on 11 March 2024 (and relevantly change the timeframe from 10 business days to 15 business days), apply to any progress claim made under the Act from 11 March 2024, regardless [of] when the contract was signed.” This issue will remain unsettled until it is considered by the Courts.
