How do I make a South Australian security of payment claim?

By Leadhand · Sources checked

In South Australia, a payment claim under the Building and Construction Industry Security of Payment Act 2009 must identify the work, goods or services, state the amount claimed and state that it is made under the Act. Check scope first, because the Act does not cover domestic building work on premises where the client lives or intends to live. Make the claim within the later of the contract period or 6 months after the last work or supply, and get advice on valid service for your case.[1][2]

Check the Act applies first

The Act applies to written or oral construction contracts. It excludes domestic building work on premises where the client resides or intends to reside, work outside South Australia and other listed cases. If your job is a home renovation for an owner-occupier, do not assume this process is available.

What the claim must contain and when it can be made

The right to a progress payment arises on a reference date. The contract can set reference dates and the Act supplies a default where it does not. A claim must identify the construction work, goods or services, state the amount claimed and state that it is made under the Act.

You can make one claim for each reference date, and it can include earlier amounts. It must be made within the later of the period in the contract or 6 months after the last work or supply.

Schedule date and payment due date are different

The respondent's payment schedule is due by the earlier of the time in the contract or 15 business days after service. Payment itself is due on the date the contract sets or, where the contract has no express provision, 15 business days after the claim. Record both dates separately.

The Act's business day excludes weekends, public holidays and 27 to 31 December. Count them that way and do not mix them with calendar days.
