How do I serve a NSW security of payment claim?

By Leadhand · Sources checked

Under the current NSW Act, identify the construction work or related goods and services, state the claimed amount and say the claim is made under the Building and Construction Industry Security of Payment Act 1999. Serve it on the person liable under your construction contract using a method allowed by section 31 or the contract. Record when and how it was served, because claim and payment clocks depend on those dates.[1][2]

Required content and monthly timing

Section 13 requires the work or supply, claimed amount and Act statement. A head contractor serving a claim on a principal must also attach the approved supporting statement relating to that claim.

A claim can be served from the last day of the month work or supply first occurred, and each later month, or an earlier date allowed by the contract. Generally only one claim may be served in a named month unless the contract provides otherwise. Unpaid amounts from a previous claim can be included.

The outside limit is the later of the contract period or 12 months after the work in the claim was last carried out or the related supply was last made. Check transitional rules for an older contract and get advice on disputed eligibility or deadlines.

How to serve it

Section 31 permits personal delivery, lodging it during normal office hours at the respondent's ordinary place of business, posting it there, or email to an address the person has specified for service of that kind of document. A contract may also provide a service method; regulations may authorise others.

Do not assume a general contact email is an address specified for service. Keep the service provision, address used, sent copy and delivery evidence. The Act treats a document posted to the ordinary place of business as served when received there.

Payment dates are a separate clock

Section 11 distinguishes non-exempt contracts from exempt residential construction contracts. Establish which category applies before entering the due date.

Payment dates are a separate clock
PaymentDate under section 11
Principal to head contractor, non-exempt contract15 business days after the claim, or an earlier contract date
Payment to subcontractor, non-exempt contract20 business days after the claim, or an earlier contract date
Exempt residential construction contractThe express contract due date; if none, 10 business days after the claim

Common questions

For the current NSW Act, it identifies the work or related supply, states the amount claimed and says it is made under the Act. It is served on the person liable under the construction contract, with a supporting statement where required.[1]

For non-exempt contracts, section 11 sets 15 business days for principal-to-head-contractor payments and 20 for payments to subcontractors, subject to an earlier contract date. For an exempt residential construction contract, use the express contract due date or, if none,10 business days.[3]
