Breach of contract: the basics explained

What is a breach of contract?

A breach of contract occurs when one party to an agreement fails to perform an obligation it promised, without a lawful excuse. Contracts create binding commitments: to deliver goods, pay a sum, complete a service, or refrain from certain conduct. When one side does not meet those commitments, the contract is said to be breached. In France, contractual obligations are governed by the Civil Code, and the general principle is that agreements lawfully formed must be honoured by the parties who entered them. This applies whether the contract is a written document signed by both sides, an exchange of emails confirming terms, or in some cases a verbal agreement supported by evidence. A breach is not the same as a simple disagreement or dissatisfaction. It requires an identifiable obligation and a failure to fulfil it. For example, if a plumber agrees to install a boiler by a fixed date and does not turn up, that is a potential breach. If the boiler is installed but the client simply prefers a different model, there is no breach because the agreed obligation was met. Understanding this distinction is the starting point for anyone facing a contract problem, because it determines whether you have grounds to act at all.

Types of breach: minor, material, and anticipatory

Not all breaches carry the same weight, and the type of breach affects the remedies available. A minor breach, sometimes called a partial breach, happens when a party fulfils most of its obligations but falls short in a small way that does not defeat the purpose of the contract. For instance, a supplier delivers the correct goods one day late without causing real harm. Here the injured party may claim compensation for any actual loss but usually cannot cancel the whole agreement. A material breach is more serious. It strikes at the heart of the contract and deprives the other party of what they reasonably expected. If a builder abandons a renovation halfway through, or a client refuses to pay a substantial invoice for completed work, the breach is material and may justify terminating the contract and seeking damages. An anticipatory breach arises when one party makes clear, before performance is due, that it will not honour its obligations. A supplier who writes to say it can no longer fulfil an order due next month is signalling an anticipatory breach. This allows the other party to react without waiting for the deadline to pass, though care is needed to confirm the refusal is genuine and unambiguous before taking action.

How to identify whether a breach has occurred

Identifying a breach begins with going back to the terms of the agreement. Read the contract carefully and pinpoint the specific obligation you believe has not been met. Ask what exactly was promised, by whom, by when, and to what standard. Vague expectations rarely support a breach claim; concrete obligations do. Next, gather evidence that the obligation was not fulfilled. This might include delivery notes, photographs of defective work, timestamps on emails, bank statements showing unpaid amounts, or written confirmations of what was agreed. It is also essential to check whether the other party had a valid excuse. Some contracts contain clauses that suspend obligations in exceptional circumstances, and the law recognises situations of force majeure where performance becomes genuinely impossible for reasons beyond a party's control. If such an excuse applies, there may be no actionable breach even though the obligation was not met. Finally, consider timing. If an obligation has a deadline that has not yet passed, the breach may not have crystallised. Working through these questions methodically helps you avoid acting prematurely and gives you a clear picture of your position before you decide how to respond.

Common examples in everyday and small business contracts

Breaches appear in many everyday situations. A tenant who stops paying rent breaches the lease. A landlord who fails to carry out urgent repairs may breach their obligations too. In consumer purchases, a retailer who delivers a faulty appliance and refuses to remedy it is in breach of its contractual duty to provide conforming goods. For small businesses, common breaches include a client who does not settle an invoice within the agreed period, a subcontractor who delivers work below the specified standard, or a supplier who ships the wrong quantity of stock. Service contracts generate frequent disputes: a web developer who misses an agreed launch date, a marketing agency that does not deliver the promised deliverables, or a freelancer who stops responding mid-project. Rental and equipment agreements can also break down, for example when returned equipment is damaged beyond normal wear. Recognising these patterns helps you spot a breach early. In each case, the analysis is the same: identify the promised obligation, confirm it was not met, and check whether any excuse applies. The practical response then depends on how serious the failure is and how much loss it has caused.

Your options when the other party breaches

When the other party breaches, several routes may be open depending on the circumstances. The first is to demand performance: you insist the party does what it agreed, perhaps by giving them a clear deadline to correct the problem. This is often the most practical outcome, especially where the relationship is worth preserving. A second option is to seek damages, meaning financial compensation for the loss the breach caused you. Compensation aims to put you in the position you would have been in had the contract been performed, so you generally need to show a real, quantifiable loss. A third possibility, reserved for serious breaches, is to terminate the contract, releasing both parties from future obligations while potentially still claiming compensation for past harm. In some cases a price reduction is appropriate, for example where goods are partly defective but still usable. Contracts sometimes specify a fixed penalty for certain failures, which can simplify the calculation of what is owed. Whichever route you consider, it is wise to act reasonably and proportionately. Overreacting to a minor breach by cancelling everything can expose you to a counterclaim, so match your response to the seriousness of the failure.

Steps to take before escalating a dispute

Before turning to formal proceedings, take steps that both protect your position and give the dispute a chance to settle. Start by communicating clearly and in writing. Explain what obligation was not met, what evidence you rely on, and what you want the other party to do. A calm, factual message often resolves misunderstandings without further conflict. If informal contact fails, a formal written notice, known in France as a mise en demeure, is usually the next step. This letter formally requests performance or correction within a stated time and creates a record that you gave the other party a fair opportunity to comply. It is often a legal prerequisite before claiming damages or terminating. Throughout, keep a complete file: copies of the contract, all correspondence, invoices, and any proof of loss. Note dates and keep messages organised, because a clear timeline strengthens your case considerably. Consider whether mediation or conciliation could help, as many disputes settle faster and more cheaply this way than through the courts. Only after these steps have been exhausted should you contemplate litigation, which is more costly and time-consuming. Careful preparation at this stage improves your chances of a favourable outcome whatever route you take.

When to consider legal or professional advice

There is a point where do-it-yourself handling of a contract dispute becomes risky, and professional advice becomes valuable. Consider seeking guidance when the sums at stake are significant relative to your finances, when the contract terms are complex or ambiguous, or when the other party has already involved a lawyer. Professional input is also sensible when you are unsure whether a breach has genuinely occurred, when force majeure or an unusual clause is being raised, or when you are weighing whether to terminate an agreement, since a wrong decision here can turn you into the party in breach. A lawyer can review your contract, assess the strength of your position, help draft a formal notice, and advise on realistic outcomes and costs. For smaller matters, other resources may help first: consumer associations, chambers of commerce, and public legal information services can offer orientation without significant expense. The aim is to make informed decisions rather than react emotionally. Getting advice early, even a single consultation, can prevent costly mistakes and clarify whether pursuing a claim is worthwhile. Loorbitnis provides educational guidance to help you understand these issues, but a professional tailored to your specific facts remains the safest step for high-stakes disputes.

FAQ

Does a verbal agreement count as a contract that can be breached? Yes, verbal agreements can be legally binding and can be breached, though proving their terms is harder. You will need evidence such as witnesses, emails, messages, or payments that confirm what was agreed. Written contracts are always easier to enforce.

Can I cancel a contract immediately if the other party breaches? Not usually. Immediate termination is generally reserved for serious, material breaches. For minor failures, you are often expected to give the other party a chance to correct the problem, typically through a formal written notice, before taking drastic action.

What is a mise en demeure and why does it matter? A mise en demeure is a formal written notice demanding that the other party perform or correct a failure within a set time. In France it is often required before you can claim damages or terminate, and it creates a clear record that you gave a fair opportunity to comply.

How is compensation for a breach usually calculated? Compensation aims to put you in the position you would have been in had the contract been performed. This means you generally need to prove a real, quantifiable loss caused by the breach. Some contracts fix a penalty amount in advance, which simplifies the calculation.

What if the other party says the breach was due to circumstances beyond their control? They may be relying on force majeure or a specific contract clause that suspends their obligations. If the event was genuinely unforeseeable and made performance impossible, there may be no actionable breach. Check your contract terms and gather evidence about what actually happened.
