⚠ Limitation periods for building contract claims can be as short as six years from the date of breach — if the project is complete and you have unresolved claims, time is running against you — submit your request now.
Does This Sound Like You?
Common building contract disputes we help with.
Contract says one thing, builder did another
The work being performed or completed does not match what is described in the contract documents, plans, or specifications. The builder is claiming everything is within scope, but you believe there is a clear departure from what was agreed. You want to know your rights and how to enforce them.
Variations were not agreed or documented in writing
The builder is claiming substantial additional payments for variation work that was never confirmed in writing. You may have had verbal discussions about changes, but you never signed a variation order and do not agree the amounts claimed are reasonable. You want to know how to dispute the variation claim effectively.
Builder claiming delay costs against you
The builder is seeking to claim delay costs or loss of productivity, alleging that delays were caused by you — late decisions, late access, variations you requested, or instructions not given on time. You dispute the cause of the delay and want to understand whether the contract supports the builder's delay cost claim.
Completion date has passed with no end in sight
The contractual completion date has passed and your project is still not finished. The builder is citing reasons for the delay but has not served any formal extension of time notices. You are incurring costs by living elsewhere, paying bridging finance, or losing rental income, and you want to know whether you can claim liquidated damages or terminate the contract.
Price significantly exceeded the original quote
The final price or the current claimed amount is substantially more than the original quote or contract price. You are not sure how much of the increase is contractually justified through legitimate variations, how much should have been included in the original scope, and whether any of the cost increases were caused by the builder's own errors or misquoting.
Contract is silent on an important issue
A dispute has arisen about something the contract does not clearly address — risk allocation for unexpected site conditions, who pays for council changes, or what standard of finish was required. You need a lawyer to advise on how the gap in the contract would be filled by implied terms, industry custom, or legislation.

Practical questions about building contract disputes.
What must a valid residential building contract include under Australian law? +
State legislation sets out minimum requirements for residential building contracts above certain values. Under the Domestic Building Contracts Act in Victoria, for example, contracts above $10,000 must be in writing, signed by both parties, and include the contract price (or basis for calculating it), a description of the work, the plans and specifications, the start and completion dates, and statutory warranties. The contract must also include information about the owner's cooling-off rights and deposit limits. A contract that does not comply with these requirements may give rise to statutory penalties against the builder and may affect the builder's right to make certain claims.
Do variations to a building contract need to be in writing? +
Under most state domestic building contracts legislation and under the standard HIA and MBA contract forms, variations must be agreed in writing and signed by both parties before the variation work commences. A builder who performs variation work without a signed written variation order may have limited ability to claim additional payment, particularly in residential building work. However, the position can be more complex where variations are carried out on the mutual understanding of both parties — a lawyer can assess whether an oral or implied variation agreement would be enforceable in your circumstances.
How do liquidated damages for delay work in building contracts? +
Liquidated damages (LDs) are a pre-agreed daily or weekly rate that the builder pays the owner for each day the project runs past the agreed completion date. To claim LDs, the completion date must still be operative — if the owner has caused delay and the builder has not been given an extension of time, the completion date may have been set at large and LDs may no longer be claimable. Conversely, if the builder has a valid entitlement to an extension of time that they have not formally claimed, the owner may still be able to claim LDs for the unextended period. Advice on the specific contract terms is essential before withholding money for delay.
What does "practical completion" mean in a building contract? +
Practical completion is the stage at which the building works are completed in accordance with the contract, except for minor omissions and defects that do not prevent the building from being used for its intended purpose. It is a critical contractual milestone — at practical completion, final payment typically becomes due, the defects liability period begins, risk generally passes to the owner, and the owner's right to occupy the premises commences. Disputes often arise about whether practical completion has been validly achieved, particularly where the owner alleges defects that the builder says are only minor. The definition in the contract itself will be the starting point for resolving this dispute.
What dispute resolution processes does a standard building contract require? +
Most standard Australian building contracts (HIA, MBA, AS4000) contain a multi-tiered dispute resolution clause requiring the parties to first try to resolve disputes by negotiation, then by mediation, before proceeding to arbitration or litigation. The contract may also require a party to first give written notice of the dispute, setting out the issues and the relief claimed. Failing to follow the contractual dispute resolution process may affect your ability to commence proceedings, so it is important to understand and follow the steps set out in your specific contract before escalating.
When can a building contract be terminated, and what are the consequences? +
Termination rights arise either under the specific contractual termination provisions or under the general law of contract. Contractual grounds typically include serious breach by either party, insolvency, abandonment, or failure to remedy a breach after written notice. Under the general law, repudiation (clear refusal to perform) gives the innocent party the right to accept the repudiation and treat the contract as at an end. The consequences of termination include rights to recover money paid beyond the value of work done, claims for additional costs to complete with a replacement contractor, and — importantly — exposure to a damages claim if the termination is found to be wrongful. Legal advice before terminating is always essential.
