Building Dispute Lawyers in Melbourne

Building disputes are won on the contract and the timeline

Every winnable building dispute looks the same on day one. There is a written building contract, dated photographs, a paper trail of variations and emails, and a clear record of what was paid and when. Owners and builders who keep that record settle for fair money. Those who don’t end up arguing in VCAT about who said what on the back deck eighteen months ago.

If you are in a building dispute in Victoria, call MK Law on 1800 130 120 today. The first call is free.

In building disputes the documents win, not the volume of the argument. The owner with the dated photos, the signed variations and the email trail beats the party relying on memory. Before you fire off a letter or a termination notice, get the file in front of a lawyer who knows how VCAT reads it.

Domestic building disputes under the DBCA

The Domestic Building Contracts Act 1995 (Vic) governs almost every residential build, renovation and extension in Victoria. It requires a written contract for any domestic building work over $10,000, sets out the statutory warranties owners receive, regulates progress payments, and gives owners specific termination rights when builders breach the contract.

Most domestic building disputes start at the free government conciliation service that screens matters before the tribunal. It used to be Domestic Building Dispute Resolution Victoria (DBDRV) and now runs inside the Building and Plumbing Commission. By law you first have to take reasonable steps to resolve the dispute yourself: contact the other party, set out your concerns in writing, and give them a real chance to respond. Conciliators can issue dispute resolution orders, and they can certify the matter for VCAT if conciliation fails. Building owners, builders, subcontractors, architects and surveyors are all eligible to apply.

VCAT’s Building and Property List hears the bulk of domestic building work disputes. For larger claims, or where the dispute involves complex commercial parties, the County Court of Victoria and the Supreme Court of Victoria take jurisdiction. Construction law in Victoria sits across all of these forums, plus the Building Appeals Board for surveyor and building-order matters.

Defective work is proved on evidence, not frustration

Cracking, water ingress, slab heave, failed waterproofing and non-compliant cladding are the defects we run most. A defect claim is only as strong as the expert report behind it, so the first job is getting an independent building inspector or engineer through the site while the evidence is fresh. We then plead the statutory warranties under section 8 of the DBCA, particularise each defect, and price the rectification. Owners who call before the builder has left site keep far more options open than those who wait until the warranty letters bounce.

The five disputes we run most weeks

Most building work that lands on our desk falls into one of five fact patterns.

Defective and incomplete work. Cracking, water ingress, slab heave, non-compliant waterproofing, plumbing that fails the audit, structural defects picked up by a private building inspector or surveyor. These claims rely on expert evidence and a careful pleading of the statutory warranties.

Delays and liquidated damages. Build periods blow out. The building contract usually sets a date for practical completion and a daily rate of liquidated damages. We act for owners chasing delay damages and for builders defending claims by relying on extension-of-time clauses, qualifying causes and superintendent decisions.

Variation disputes. Section 38 of the DBCA sets strict rules for variations. A variation that was not requested in writing, costed in writing, and signed off by the owner is usually not recoverable. Builders routinely lose six-figure variation claims on this point alone.

Progress claim disputes. When a progress claim is disputed, money stops. Cash flow problems escalate to suspension of work, termination, and counterclaims. Security of Payment is often the fastest way to get paid.

Termination and builder walk-offs. Wrongful termination is one of the most expensive mistakes in domestic building. Before any termination notice is served, the grounds, the notice, and the timing all need to be right. Get a lawyer on the phone before the email is sent.

Outside those five sits whatever an incident on site leaves behind. A construction accident puts indemnity clauses, insurance policies and stop-work delay costs in play at once, and that argument runs on its own track beside any defect claim already on foot.

Security of Payment is fast and brutal

The Building and Construction Industry Security of Payment Act 2002 (Vic) gives anyone working under a construction contract a quick path to payment.

A payment claim is served on the principal. The principal has ten business days to serve a payment schedule setting out what they propose to pay and why. If no schedule comes back, the entire claim becomes payable. If the schedule disputes the amount, the claimant can refer the dispute to an adjudicator who decides the matter inside about a month, far faster than litigation in any court or tribunal.

The timeframes are unforgiving. A day late on the payment schedule is a day too late. Builders, subcontractors and consultants who run their books on Security of Payment get paid faster than anyone else in the industry. We draft and respond to payment claims, payment schedules and adjudication applications across Victoria.

Residential and commercial building disputes

Residential disputes run through the DBCA and, in most cases, Building and Plumbing Commission conciliation before VCAT. Commercial building and construction disputes turn instead on the negotiated contract: the dispute resolution clause usually steps the parties through negotiation, then mediation or expert determination, then arbitration or court. We act for property developers, head contractors, subcontractors, engineers, architects and owners corporations on both sides of that line.

Owners corporation disputes deserve their own mention. Defects in common property, water damage between lots and disagreements over who funds rectification are a constant source of litigation. We act for owners corporations and individual lot owners, and coordinate the building claim with the owners corporation’s obligations under the relevant Victorian legislation.

What happens if the builder is insolvent

Builder insolvency is the worst outcome for an owner who is mid-build. The site stops, subcontractors walk, and unpaid progress claims become a queue behind the secured creditors.

Builder insurance is the real remedy for a homeowner, and the cover you hold depends on when you signed. A contract signed from 1 July 2026 falls under the first-resort Home Warranty Scheme, run by the Building and Plumbing Commission. It picks up work over $20,000, has a $400,000 limit, and you can claim for incomplete or defective work without waiting for the builder to collapse. A policy issued before that date is last-resort cover through the VMIA. It picks up work over $16,000 to a $300,000 limit, and you can only claim once the builder has died, disappeared, become insolvent or had their registration cancelled. Deadlines are tight either way, and insurers will look for a reason to decline, so get the claim moving early. We run claims under both schemes.

For builders facing a principal that has gone under, recovery usually runs through proofs of debt, retention release claims, and where security exists, calls on bank guarantees. Our insolvency lawyers work alongside the building team where a counterparty has collapsed.

A payment claim done right gets you paid in weeks

Security of Payment rewards the party who moves first and gets the paperwork right. A payment claim served under the 2002 Act starts a ten business day clock: if the principal fails to serve a payment schedule in time, the whole amount falls due and you can recover it as a debt. Where the schedule short-pays you, adjudication puts the dispute in front of an independent adjudicator who decides it inside about a month. We prepare and respond to claims, schedules and adjudication applications for builders, subcontractors and consultants across Melbourne.

Recover what you are owed

Where we appear

We provide legal representation in VCAT’s Building and Property List, the Building Appeals Board, the County Court of Victoria and the Supreme Court of Victoria. Most matters end at conciliation, a compulsory conference or mediation. A small number run to a contested hearing, and when they do, the same lawyers who drafted your first letter to the builder are the ones at the bar table.

What it costs

The first call is free, and we scope your matter on it. After that, cost follows the forum, how far the matter runs, and how much expert evidence it needs. A file that settles at conciliation costs a fraction of a contested VCAT hearing with duelling experts.
