Breach of Contract Claims: How Commercial Litigation Lawyers Prove Your Case

When a business partner fails to deliver on their promises, or a supplier doesn’t meet their contractual obligations, you’re facing a potential breach of contract.

Contract disputes can disrupt your business operations, damage relationships, and impact your bottom line. Understanding how commercial litigation lawyers build and prove your case can make the difference between a costly setback and a successful resolution.

Contract breaches happen more often than many business owners realise. Whether it’s a client refusing to pay for services rendered, a contractor delivering substandard work, or a business partner walking away from their commitments, these situations require swift and strategic legal action.

The key to success lies in understanding exactly what evidence you need and how skilled lawyers can achieve the best possible outcome.

What Constitutes a Breach of Contract?

A breach of contract happens when one party fails to meet their agreed obligations without a valid legal reason. This could mean not paying on time, delivering poor-quality work, not delivering at all, or stepping outside the agreed-upon terms.

Common Breaches in Australian Business

Non-payment: The most common example; someone simply doesn’t pay what’s owed.

Late delivery: Goods or services are provided outside of agreed timeframes.

Substandard work: Deliverables don’t meet the promised standard or requirements.

Non-delivery: Goods or services aren’t delivered at all.

Misrepresentation: Providing false information to get the contract signed.

Not every failure is a breach significant enough for legal action. Whether you can claim—and what you can claim—depends on the contract itself and the severity of the breach.

Businesses often rely on commercial lawyers in North Sydney, Bankstown, or Bondi for swift, strategic advice on contract disputes and litigation.

The Four Essential Elements Your Lawyer Must Prove

To succeed in a breach of contract claim in Australia, your commercial litigation lawyer must establish four critical elements: that a valid, binding contract existed; that you fulfilled your obligations; that the other party failed to fulfill their contractual obligations; and that this breach caused you damage or loss.

1. Proving a Valid Contract Existed

Your lawyer’s first task is to demonstrate that a legally binding contract was in place. This requires showing five essential elements: agreement between the parties, consideration (something of value exchanged), capacity to enter legal relations, intention by the parties to enter into legal relations, and legality of purpose.

Your lawyer will gather evidence, including written agreements, email correspondence, purchase orders, invoices, and even witness testimony about verbal agreements. In commercial relationships, courts generally presume that parties intended to create legal relations, which works in your favour.

2. Establishing Your Performance

The second element requires proving that you held up your end of the bargain. Your lawyer will compile evidence showing that you either fully performed your contractual obligations or were ready and willing to perform but were prevented from doing so by the other party’s breach.

This evidence might include delivery receipts, completion certificates, payment records, photographs of completed work, or correspondence showing your attempts to fulfil your obligations.

3. Demonstrating the Other Party’s Breach

This is often the most contentious element, requiring your lawyer to clearly show how the other party failed to meet their contractual obligations. The evidence needed depends on the specific facts of your case and the terms of your particular contract.

Your lawyer will meticulously compare the other party’s actual performance against what the contract required. This might involve analysing delivery dates, quality specifications, payment terms, or performance standards. They’ll gather documentary evidence such as correspondence acknowledging the failure, expert reports on substandard work, or records showing missed deadlines.

4. Proving Damages and Causation

Finally, your lawyer must demonstrate that the breach actually caused you to suffer losses and quantify those damages. This is often the most challenging aspect of the case, requiring detailed financial analysis and expert testimony.

The damages you can recover typically include direct losses flowing naturally from the breach, as well as consequential losses that were reasonably foreseeable at the time the contract was made. Your lawyer will work with accountants, industry experts, and other professionals to calculate your actual losses.

Types of Evidence That Strengthen Your Case

Commercial litigation lawyers know that strong evidence is the foundation of a successful breach of contract claim. The quality and comprehensiveness of your evidence often determines whether you’ll achieve a favourable settlement or need to proceed to trial.

Documentary Evidence

The backbone of any contract dispute is documentary evidence. Your lawyer will systematically gather and organise all relevant documents, starting with the contract itself and any amendments. This includes correspondence between the parties, purchase orders, invoices, delivery receipts, payment records, and any documents that show the parties’ understanding of their obligations.

Email communications are particularly valuable because they often reveal the parties’ intentions and acknowledgements of problems. Text messages can also provide crucial evidence of admissions or attempts to resolve issues.

Financial Records and Expert Analysis

Proving damages requires meticulous financial documentation. Your lawyer will work with forensic accountants to analyse your financial records and quantify your losses. This might involve comparing your financial position before and after the breach, calculating lost profits based on historical performance, or determining the cost to rectify defective performance.

Expert reports from industry professionals can be crucial in establishing both the standard of performance required and how the other party’s performance fell short.

Witness Testimony

While written evidence is preferred, witness testimony can provide crucial context and fill gaps in the documentary record. Your lawyer will identify key witnesses who can testify about the formation of the contract, the parties’ performance, and the impact of the breach.

The Litigation Process: What to Expect

Understanding the litigation process helps you prepare for what lies ahead and work effectively with your legal team.

Pre-Litigation Steps

Before filing court proceedings, your lawyer will typically attempt to resolve the dispute through direct negotiation. This might involve issuing a formal notice of breach that clearly outlines how the other party has breached the contract, provides supporting evidence, specifies the remedy you’re seeking, and sets a reasonable deadline for response.

Many disputes settle at this stage, particularly when the evidence is strong and the other party recognises their liability.

Court Proceedings

If pre-litigation efforts fail, your lawyer will commence formal court proceedings. This involves filing a statement of claim that sets out your case in detail, including the facts, the legal basis for your claim, and the remedies you’re seeking.

Courts often encourage alternative dispute resolution methods like mediation or arbitration, which offer faster and less formal processes compared to traditional litigation.

Defences: What Might the Other Side Argue?

The other party may claim:

No valid contract existed.

They completed their part.

You didn’t fulfil your own obligations.

The loss would have happened anyway.

The contract was unfair, void, or “frustrated” by events outside their control.

A lawyer anticipates these issues, closes gaps in the evidence, and structures your claim to withstand scrutiny.

Calculating and Proving Damages

One of the most complex aspects of breach of contract claims is accurately calculating and proving your damages. In Australian contract law, you can generally recover damages that flow naturally from the breach or were reasonably foreseeable at the time the contract was made.

You have a duty to take reasonable steps to minimise your losses following a breach. Your lawyer will document the steps you took to mitigate your damages and demonstrate that these efforts were reasonable in the circumstances.

Proving lost profits or business opportunities requires sophisticated financial analysis. Your lawyer will work with forensic accountants to analyse your historical performance, market conditions, and the specific impact of the breach on your business operations.

When Settlement Makes Sense

While pursuing your legal rights is important, settlement often provides the most practical resolution to contract disputes.

Your lawyer will continuously evaluate settlement opportunities throughout the litigation process, considering the strength of your legal case, the likely quantum of damages, and the commercial value of reaching resolution quickly.

Experienced commercial litigation lawyers often identify settlement solutions that go beyond simple monetary payments, including ongoing business relationships or performance guarantees that address your underlying business needs.

Remedies: What Can You Actually Get?

Australian courts offer a range of remedies depending on the context and seriousness of the breach:

Damages: Monetary compensation is the most common remedy. The goal is to put you where you’d be if the breach hadn’t happened, typically including lost profits or actual losses.

Termination: For serious breaches, you can end the contract and claim compensation.

Specific Performance: The court may order the party to fulfil their promise (most common in property sale cases).

Injunctions: Court orders stopping the other party from doing something that would breach the contract further
