Best Construction Lawyers in Australia
Updated 22 September 2026
Compare construction lawyers in Australia by city, then check your deadline: under the state security of payment Acts, a payment schedule answering a payment claim is due within 10 or 15 business days, depending on the state. Construction lawyers recover and defend progress payments, draft building contracts, and run building and defect disputes in tribunals and courts.
Before you contact a construction lawyer, gather the contract, any payment claim or payment schedule, variations, correspondence and photos of defects. Note the date each document was served. Security of payment time limits run in business days from service, so that date decides whether a claim can still go to adjudication. The lists below are ordered using the method explained in how we rank law firms.

What does a construction lawyer do?
A construction lawyer (also called a building dispute lawyer) acts for principals, head contractors, subcontractors, suppliers and homeowners. Typical tasks are:
- Draft and review construction contracts, subcontracts and variation clauses.
- Prepare and serve payment claims under the state security of payment Act.
- Prepare payment schedules that dispute or reduce a claim, with reasons.
- File and respond to adjudication applications.
- Enforce adjudication determinations through the courts.
- Run home building and defect claims in state tribunals.
- Negotiate delay, extension-of-time and liquidated damages disputes.
- Advise on retention money, bank guarantees and builder or subcontractor insolvency.
- Represent parties in mediation, expert determination, arbitration and court.
When do you need a construction lawyer?
You need one when a statutory deadline is running or a dispute is likely to reach a tribunal or court.
When you have been served with a payment claim
The payment schedule deadline is short and strict. In NSW, under section 14(4) of the Building and Construction Industry Security of Payment Act 1999 (NSW), a respondent who does not provide a payment schedule in time becomes liable to pay the claimed amount on the due date. Victoria, South Australia and the ACT have the same rule.
When your payment claim has not been paid
A claimant can apply for adjudication when the scheduled amount is less than the claimed amount or the respondent fails to pay. The window is short. In Western Australia, for example, an adjudication application must be made within 20 business days after the claimant first becomes entitled to make it.
When a home building dispute arises
Homeowners and builders usually resolve defect, delay and payment disputes through a state tribunal, after any compulsory dispute resolution step. See the table below.
When you are signing a major contract
A lawyer reviews payment terms, time bars, liquidated damages and security before you sign. Changes are cheaper at this stage than after a dispute starts.
Which security of payment Act applies in each state?
Each state and territory has its own security of payment Act. The deadline for a payment schedule is the earlier of the time in the contract and the statutory period below (as at September 2026).
| State or territory | Act | Payment schedule due |
|---|---|---|
| New South Wales | Building and Construction Industry Security of Payment Act 1999 | 10 business days after the claim is served |
| Victoria | Building and Construction Industry Security of Payment Act 2002 | 10 business days after the claim is served |
| Queensland | Building Industry Fairness (Security of Payment) Act 2017 | 15 business days after the claim is given |
| Western Australia | Building and Construction Industry (Security of Payment) Act 2021 | 15 business days after the claim is made |
| South Australia | Building and Construction Industry Security of Payment Act 2009 | 15 business days after the claim is served |
| Tasmania | Building and Construction Industry Security of Payment Act 2009 | 10 business days (20 for an owner building a home who is not a building practitioner) |
| ACT | Building and Construction Industry (Security of Payment) Act 2009 | 10 business days after the claim is given |
| Northern Territory | Construction Contracts (Security of Payments) Act 2004 | Notice of dispute within 10 working days, if the contract is silent |
Two state details matter. In Queensland, a payment claim (other than a final claim) must generally be given within the contract period or 6 months after the work was last carried out, whichever is longer. In Victoria, the Building Legislation Amendment (Fairer Payments on Jobsites and Other Matters) Act 2025 amended the Act from 15 April 2026, so advice based on the older Victorian rules may be out of date.
Payment disputes on Queensland projects are run under the Queensland Act, and you can compare firms that handle them in Construction Lawyers in Brisbane. Western Australian projects fall under the 2021 Act, and local firms are compared in Construction Lawyers in Perth.
How are home building disputes resolved?
Home building disputes go to a state tribunal, often after a compulsory first step.
| State | Tribunal | Key rule |
|---|---|---|
| New South Wales | NSW Civil and Administrative Tribunal (NCAT) | NCAT hears building claims up to $500,000 (Home Building Act 1989 s 48K). Statutory warranty claims must start within 6 years for a major defect or 2 years for other defects, counted from completion (s 18E). |
| Victoria | Victorian Civil and Administrative Tribunal (VCAT) | A certificate of conciliation from the chief dispute resolution officer is needed before applying to VCAT (Domestic Building Contracts Act 1995 s 56). |
| Queensland | Queensland Civil and Administrative Tribunal (QCAT) | A party must first follow the QBCC's dispute resolution process (Queensland Building and Construction Commission Act 1991 s 77). |
Both sides use the same pathway. In Victoria the rule applies to any party to a domestic building work dispute, and in Queensland to any person involved in a building dispute, so a builder chasing an unpaid final payment follows the same steps as a homeowner claiming defects.
How much does a construction lawyer cost?
Construction lawyers in Australia typically charge between $350 and $800 or more per hour plus GST, and partners in capital-city firms often charge more. These are market estimates, not official rates, and they vary by firm and matter.
| Matter | Typical fee model | Typical range (estimate) |
|---|---|---|
| Contract review | Fixed fee or hourly | $1,000–$5,000 |
| Payment claim or payment schedule | Fixed fee or hourly | $1,000–$4,000 |

| Tribunal home building dispute | Hourly | $10,000–$60,000+ |
| Supreme Court construction litigation | Hourly | $100,000+ |
In NSW, Victoria and Western Australia, section 174 of the Legal Profession Uniform Law requires a law practice to disclose the basis of its costs and an estimate of total costs when you first give instructions. The guide How Much Does a Lawyer Cost in Australia? compares fee models across practice areas.
How to choose a construction lawyer
Use checks you can verify:
- Practising certificate. Confirm the lawyer holds a current certificate on the state law society or regulator register.
- Specialist accreditation. Accreditation areas differ by state, so check the law society's register. What Is an Accredited Specialist Lawyer? explains the schemes.
- Security of payment experience. Ask how many adjudications the lawyer has run under your state's Act, for claimants and respondents.
- Side of the industry. Some firms act mainly for builders and head contractors, others for subcontractors or homeowners. Check for conflicts early.
- Written costs disclosure. Expect an estimate of total costs and the billing method in writing.
The guide How to Choose a Lawyer in Australia sets out general questions to ask at a first meeting.

Frequently asked questions
How long do I have to respond to a payment claim?
A payment schedule is due within 10 business days in NSW, Victoria, Tasmania and the ACT, and within 15 business days in Queensland, Western Australia and South Australia, or earlier if the contract requires. In the Northern Territory the implied term is 10 working days where the contract is silent.
What happens if I miss the payment schedule deadline?
In NSW, Victoria, South Australia and the ACT, the respondent becomes liable to pay the full claimed amount on the due date for the progress payment. In Queensland, failing to give a payment schedule on time is also an offence carrying a maximum penalty of 100 penalty units.
How long do I have to sue a builder for defects in NSW?
Under section 18E of the Home Building Act 1989 (NSW), proceedings for breach of a statutory warranty must start within 6 years for a major defect or 2 years for any other defect, counted from completion of the work.

No. Under section 56 of the Domestic Building Contracts Act 1995 (Vic), a party needs a certificate of conciliation before applying to VCAT, except for injunction-type orders.
Is a building dispute lawyer the same as a construction lawyer?
Yes. Both terms describe solicitors who practise construction law. Some focus on commercial projects and payment disputes, while others focus on residential building and defect claims.
