Breach of Contract: Legal Definition, Non-performance, Damages and Remedies

What is a Breach of Contract?

A breach of contract is the failure by one party to fulfil their obligations under the contract, which can lead to legal disputes and remedies.

Breach of Contract Legal Meaning

Breach of contract is a fundamental concept in contract law, occurring when one party fails to fulfil their obligations under a contract.

This failure can manifest in various ways, such as non-performance, partial performance, or performance that is substandard or substantially different from what was agreed upon. The legal implications of a breach of contract are significant, often leading to remedies and disputes.

Definition and Types of Breach of Contract

A breach of contract is defined as the failure, without legal excuse, to perform any promise that forms all or part of the contract. This can include failure to deliver goods, pay on time, complete a project, or any other act promised in the contract. There are different types of breaches:

  • Material Breach: A material breach is a substantial failure to perform, which defeats the contract’s purpose. It gives the aggrieved party the right to terminate the contract and seek damages.

  • Minor Breach: This is a less serious breach that does not render the contract irreparable. The non-breaching party cannot terminate the contract but can seek damages.

  • Anticipatory Breach: When one party makes it known they will not fulfil their contractual obligations, either through words or actions, before they are due to perform.

  • Actual Breach: Occurs when a party refuses to perform their obligation on the due date or performs incompletely or improperly.

Legal Remedies for Breach of Contract

When a breach of contract occurs, the non-breaching party has several remedies:

  • Damages: The most common remedy, damages are meant to compensate the non-breaching party for losses incurred. This can include compensatory, punitive, nominal, and liquidated damages.

  • Cancellation and Restitution: The non-breaching party is allowed to cancel the contract and is entitled to restitution.

Can A Party Unilaterally Amend A Contract Without Causing A Breach?

A party cannot unilaterally amend a contract without causing a breach. Contract amendments require mutual consent from all parties involved. Unilateral changes without agreement typically constitute a breach of the original contract terms.

The parties must negotiate and agree to any modifications, often formalising them in writing, to ensure the contract remains valid and enforceable.

Any attempt to unilaterally change a contract without the other party’s consent undermines the contract’s legal integrity and can lead to disputes or legal challenges.

What Is A Constructive Breach of Contract?

A constructive breach of contract occurs when one party’s actions or failure to act makes it impossible for the other party to perform their obligations, effectively rendering the contract irreparably broken. This breach is not due to a direct refusal to fulfil the contract terms but rather an indirect or implied breach.

It occurs when a party’s conduct significantly changes the essence of the agreed terms, leading the other party to reasonably conclude that the contract’s obligations will not be properly fulfilled.

Analysing Breach of Contract

The analysis of a breach of contract involves several steps:

  • Establishing the Existence of a Contract: The first step is to confirm that a valid contract existed. This involves proving an offer, acceptance, consideration, mutual assent, and, in some cases, a written agreement.

  • Determining the Breach: Next, it must be determined whether a breach occurred and its type. This involves examining the contract terms and the actions or inactions of the involved parties.

  • Assessing Damages: The non-breaching party must prove the damages caused by the breach. This can involve complex financial calculations, especially in business contracts.

  • Considering Defences: The breaching party may have legal defences, such as impossibility, impracticability, waiver, or estoppel, which can excuse or justify the breach.

  • Legal Proceedings: If a resolution is not reached through negotiation or arbitration, the case may proceed to court. The court will examine the evidence, apply relevant laws, and decide on the appropriate remedy.

Can Non-Performance Due To Force Majeure Be Considered A Breach?

Non-performance due to force majeure is generally not considered a breach of contract. Force majeure refers to unforeseeable circumstances, such as natural disasters, war, or other extreme events, that prevent a party from fulfilling their contractual obligations.

If a contract includes a force majeure clause, it typically excuses the affected party from liability for non-performance under these extraordinary circumstances. Courts interpret these clauses based on the contract’s specific language and context.

The invoking party must demonstrate that the force majeure event was unforeseeable and directly impeded their ability to perform the contract.

How Do Courts Determine Damages For Breach of Contract?

In determining damages for breach of contract, courts aim to compensate the injured party for the loss incurred due to the breach. This assessment often involves calculating the difference between the contract’s value if it had been fully performed and its value after the breach.

Courts consider the direct and foreseeable losses stemming from the breach, including lost profits and additional costs incurred.

The goal is to put the non-breaching party in the position they would have been in if the contract had been fulfilled. However, the injured party must also demonstrate efforts to mitigate their losses to be eligible for full compensation.


Understanding the legal implications of breach of contract is crucial in both personal and business realms. Parties should be aware of their contractual obligations and potential consequences of non-compliance.

As contract disputes can be complex and vary significantly depending on the circumstances, legal advice is often necessary to navigate these issues.

In summary, breach of contract is a legal issue with many remedies and defences. It requires careful analysis of the contract terms, parties’ actions, and applicable laws to determine the appropriate course of action.
