Construction Contracts
in Melbourne

A construction contract lawyer in Melbourne helps homeowners, builders, and contractors review, draft, negotiate, and enforce building contracts. They ensure the agreement complies with the Domestic Building Contracts Act 1995 (Vic), identify unfair or risky terms, advise on your legal rights, and represent you at VCAT or in court if disputes arise. At Construction Lawyer Melbourne, every matter is handled personally by John Dela Cruz — a principal solicitor with 17+ years of exclusive construction law experience.

Under the Domestic Building Contracts Act 1995 (Vic), major domestic building contracts must include: the names and addresses of all parties; the date; a description of the work to be performed; the contract price or how it is to be calculated; the start date and anticipated completion date; the payment schedule; details of any prime cost and provisional sum items; statutory warranties; and a cooling-off notice. Note that the Act applies to residential building work valued at $10,000 or more. Many disputes arise because contracts omit these mandatory elements or contain ambiguous terms. A construction contract review ensures full compliance before you sign.

A Lump Sum (fixed-price) contract sets an agreed total price before work begins, providing cost certainty for the homeowner but potentially higher risk for the builder if costs escalate. A Cost Plus contract reimburses the builder for actual costs incurred (labour, materials, etc.) plus an agreed fee or percentage. Cost Plus contracts can suit complex renovations where the full scope is difficult to define upfront, but they carry the risk of cost overruns for homeowners without careful controls. In Victoria, Cost Plus contracts are generally restricted to contracts over $1 million or certain renovation projects. Our lawyers can advise which structure best suits your project and what protections to include.

Yes, a construction contract can be varied after signing, but only through a formal written variation agreement signed by both parties. Verbal variations are generally unenforceable under Victorian building law. Under the Domestic Building Contracts Act 1995 (Vic), variations must comply with strict requirements, including written documentation and disclosure of the cost impact. If you have already signed a contract and wish to negotiate amendments, we can assist with a formal variation agreement to protect your legal position.

While Victorian law does not impose the same mandatory written contract requirements on subcontract agreements as it does on principal domestic building contracts, a written subcontract is strongly recommended. A properly drafted subcontract agreement protects your payment rights under the Building and Construction Industry Security of Payment Act 2002 (Vic), clearly defines the scope of work, allocates risks appropriately, and provides an enforceable basis for debt recovery if disputes arise. Operating without a written subcontract exposes both parties to significant risk.

If your builder breaches the contract — for example, by abandoning the works, performing defective work, or failing to complete on time — you may have the right to issue a show cause notice, suspend payments, or in serious cases, terminate the contract. Breaches involving defective or incomplete domestic building work in Victoria can be brought before the Victorian Civil and Administrative Tribunal (VCAT) under the Building and Property List. Our construction lawyers can assess your legal position, advise on the appropriate steps, and represent you at VCAT if required.

Your fixed-fee cost disclosure is provided within 24 business hours of confirming your interest. Once you accept and secure payment, your comprehensive contract review report is delivered via email within 2 business days. This fast turnaround ensures you can make informed decisions quickly — even when builders are applying pressure to sign immediately. The review is entirely online; there is no need to visit our Melbourne office.

Under the Domestic Building Contracts Act 1995 (Vic), builders provide statutory warranties that cannot be contracted out of. These include that the work will be carried out in a proper and workmanlike manner, in accordance with the plans and specifications; that materials will be good and suitable; that the work will comply with all laws and legal requirements; and that the work will be reasonably fit for the purpose. Warranty periods and enforcement mechanisms are strictly regulated. If your builder is refusing to honour these warranties, contact us to discuss your enforcement options.

Early legal advice prevents expensive disputes. Building contracts contain complex legal terms that can expose you to cost overruns, delays, defective work, and lengthy VCAT proceedings. Most homeowners sign without understanding unfair terms that heavily favour builders. A pre-signature contract review identifies these risks when you still have negotiating power — before you are legally bound. Problems that cost thousands to resolve later can often be prevented with a fixed-fee review now. It is an investment that protects your most significant financial commitment.

Yes. Under the Domestic Building Contracts Act 1995 (Vic), for major domestic building contracts the homeowner has a 5 business day cooling-off period after receiving a copy of the signed contract. During this period you can rescind the contract without penalty. If you have already signed but have concerns, contact us immediately to assess whether your cooling-off rights remain available, or whether negotiation of contract amendments is still possible.
