A person who, under a construction contract, has carried out construction work and/or supplied related goods and services is entitled to receive a progress payment for work performed.
The claimant (the person claiming a progress payment) may serve a payment claim on and from the last day of the named month in which the construction work was first carried out (or related goods and services were first supplied) under the contract and on and from the last day of each subsequent named month.
However, if the construction contract makes provision for an earlier date in a named month (e.g. 25th of the month), than that will be the applicable date rather than the last day of the month.
If a construction contract has been terminated, a payment claim can be served on and from the date of termination.
Adjudicate Today knows that making payment claims which comply with the requirements of the Act can be challenging.
You need to indicate the amount owed, describe the items and quantities of the work or service provided and, if applicable, attach necessary documents e.g. completion certificates, dockets confirming the receipt of goods. There are rules about when payment claims can be made. If you make a claim about residential work, there are more rules. While we encourage you to read below, our online wizard is available to walk you through each step in making and serving a valid payment claim.
Our wizards are smart but to use them you need to establish a free and no obligation 'Lockbox'. The Lockbox is yours and can't be accessed by Adjudicate Today staff or anyone else without your express permission. Adjudicate Today does not charge for creating your Lockbox or using our wizards. Your Lockbox allows you to save and print the payment claim. If generating your payment claim via your Lockbox Wizard, a PDF document will be generated which contains a link to the files in your Lockbox for this particular payment claim. If service of the payment claim is agreed to between the parties by Lockbox or electronic link, then you may download and send this PDF document to the other party. If service of the payment claim is agreed to between the parties by email, then you must download all files in the link in this PDF and send those files as an attachment to the email. You must otherwise download all files, print them and provide them to the Respondent, preferably by courier. The Lockbox can remind you when payments are overdue. To use your Lockbox and access Adjudicate Today wizards click here, otherwise continue to read below for manual assistance in making a payment claim and/or clarification of any uncertainties in completing our online payment claim wizard. In all cases, the Claimant MUST make its own enquiries to satisfy itself of the most suitable method of service.
It is important to provide the information requested by our payment wizard. Courts have held that works must be sufficiently identified in the payment claim and 'it is not up to the recipient to sort through previous payment claims to ascertain work to which a new payment claim related'.
A payment claim is a written progress claim (invoice) which allows recovery of money owed using the Act.
It must:
A progress claim may include:
This does not prevent the claimant making one payment claim for a progress payment in any particular month for construction work carried out or for related goods and services supplied in that month.
Ensure the payment claim is addressed to the legal entity that the claimant contracted with (the respondent). It is no use seeking an adjudication determination against a respondent if the name and/or ACN/ABN is incorrect. Courts won't enforce determinations unless the name and ACN/ABN of the respondent match. Here are three examples (with names changed) of problems encountered.
Those who can make a payment claim under the Act include:
Construction work and services can be claimed under the Act even if the contract is not written and/or does not provide for progress payments. e.g. a contract provision providing for a single payment to be made when work is completed is unenforceable. Claimants are entitled to be paid every month.
Construction work and the supply of related goods and services includes:
A claimant can make a payment claim on the respondent for:
A payment claim should include all information necessary for a respondent to both identify the work and how the sum claimed is calculated. During adjudication, some respondents have successfully argued that they could not approve payment because the work claimed was so vague as to make it impossible to be confidently valued.
Where available, payment claims should include attachments such as:

Unless otherwise agreed by the parties, the payment claim must be provided to the respondent during normal business hours at the respondent's ordinary place of business or in accordance with the WA Electronic Transactions Act 2011 section 14. Your lockbox may be used to electronically serve documents.
In our experience, below is the safest ranking to ensure service:
A claimant is entitled to be paid a valid progress payment claim by the due date for payment.
Once a payment claim has been given under the Act, the due date for payment depends upon the claimant's position in the contractual chain.

Yes, but only in relation to a contracts with an individual (natural person) residential homeowner where the total value of the contract, including variations, is more than $500,000 (including GST). When such payment claim is served on an individual (natural person) residential homeowner (the respondent), it must be accompanied by a supporting statement. The supporting statement, required by the WA Government, is available here. If the supporting statement is not included, it is not a valid payment claim.
However:
The next step in our flowchart provides crucial information for both claimants and respondents. Depending on whether a respondent does or does not provide a payment schedule to the claimant within 15 business days' results in different time frames and procedures.
The respondent who fails to provide a payment schedule within 15 business days must be given a second opportunity to provide one. If it fails a second time, the Act effectively punishes the respondent by denying it the right to participate in the adjudication process.
Please move to the next step on the flowchart being "Respondent has 15 business days after receipt of the Payment Claim (or shorter period if provided by construction contract) to prepare and serve a Payment Schedule".
