Key Takeaways:

  • Proving breach of contract requires showing that a valid contract existed, one party performed as required, the other party failed to perform, and damages resulted.
  • The severity of the breach (material vs. minor) affects the available legal remedies.
  • Common defenses include impossibility, mutual mistake, duress, and waiver.
  • Evidence such as the original contract, communication records, and performance documentation is crucial.
  • Legal remedies include compensatory damages, specific performance, rescission, and restitution.

Proving a breach of contract requires examining the contract and making sure it's enforceable, and then providing evidence that one party did not fulfill their end of the bargain.

A breach of contract occurs when one or both parties have failed to do what they agreed to do in a contract. This type of failure is the driving force behind many lawsuits. A few typical examples include a plumber's failure to fix a restroom, a famous person's failure to appear at an event, or a tenant's failure to make rent payments.

How to Determine Whether a Contract Has Been Breached

To determine whether a contract has been breached, you must first review the required material terms of the agreement. Elements of a contract may be considered material if they comprise the very purpose of making the agreement, meaning that failure to perform them defeats that purpose.

Material elements may include important items such as the time frame of completion, an item to be sold, a technique or particular way of completing a service, or an amount of money to be paid. If, without meeting these terms, the agreement would be meaningless, they constitute material elements. As such, if these requirements are not met, then the contract has been breached.

As an example, if you entered into a contract with a clown to perform at your child's birthday party, and the agreement specifies that the birthday party is from noon until 2 p.m., it would likely be considered a material breach if the clown showed up at noon and then said she needed to leave by 12:30 p.m. However, a court might not consider it to be a material breach if the clown arrived at 12:15 p.m. due to an accident on the highway, and stayed until 2 p.m.

Similarly, if you entered into an agreement to purchase a new truck, and it arrived with slightly mismatching tinted windows, a court would not likely conclude that a material breach of contract had occurred. Although the vehicle dealer might need to replace the glass if a particular tint was included in the contract, you would not be able to void the entire agreement.

You may also consider the substantial performance of either party. This also might prevent a court from finding a valid material breach. If the party has completed the majority of what was required under the contract, it may be considered substantial enough to uphold the contract. However, such conclusions might require some remedy to make up for whatever part of the agreement is left unfinished.

As an example, if Diego agrees to deep clean Maria's kitchen for $100, and then thoroughly cleans all floors, appliances, counters, windows, fridge, and stove, yet does not dust the blades on the ceiling fan, a court would probably determine that the contract was substantially completed. It's possible that a small amount may be deducted from Diego's pay in order to pay someone else to clean the fan blades.

Or, if a contractor agrees to install a floor using a particular type of material, but uses a different material instead, the court will need to determine whether the job was substantially performed. If both materials are of equal color, style, and quality, it's likely that no valid breach has occurred.

How to Prove a Prove Breach of Contract

In order to prove a breach of contract, the contract must first be proven to be enforceable. This requires the following four elements:

  1. Offer: Two or more parties must have the intention to enter a legally binding contract. Not all discussions pertaining to future business agreements are considered offers.
  2. Consideration: Each party agrees to give and receive something of value. A one-way promise is generally not considered a valid contract. Neither are agreements based on already completed actions.
  3. Acceptance: This occurs when all parties have agreed to the terms of the contract.
  4. Mutuality: After discussion, all parties understand and agree to the terms.

After it has been established that an enforceable contract was in place, you must prove that you satisfied your requirements under the contract terms.

You must also prove that the other party did not perform their obligations under the contract terms. In other words, you must prove that the defendant caused a breach of contract.

Next, you must prove how that particular breach resulted in specific damages. "Damages" is a term that includes any lost money, lost working time, or any other quantifiable expense that occurred as a result of the breach of contract. You must be able to prove that as a result of the breach of contract, you will lose money, a business opportunity, or experience some other clearly identifiable harm.

Types of Breaches and Their Legal Consequences

When proving breach of contract, it's important to identify the nature of the breach. Not all breaches are treated equally under the law, and the classification may affect your legal strategy and the remedies available. Breaches generally fall into the following categories:

  • Material Breach: A major failure to perform that goes to the heart of the contract. This usually allows the non-breaching party to terminate the agreement and sue for damages.
  • Minor (Immaterial) Breach: A partial or slight failure that does not destroy the value of the contract. The contract remains in effect, but the non-breaching party may seek damages.
  • Anticipatory Breach: Occurs when one party indicates they will not perform their contractual obligations before performance is due.
  • Actual Breach: A straightforward refusal or failure to perform contractual duties when they are due.

Understanding the type of breach can help determine whether litigation is justified and what damages or remedies might be pursued.

Common Legal Defenses to a Breach of Contract Claim

When you're trying to prove breach of contract, the defendant may raise legal defenses that could invalidate or mitigate the claim. Common defenses include:

  • Impossibility or Impracticability: Performance became impossible or unreasonably difficult due to unforeseen circumstances.
  • Mutual Mistake: Both parties misunderstood a basic fact essential to the contract.
  • Duress or Undue Influence: One party was forced or unfairly pressured into the agreement.
  • Fraud or Misrepresentation: The contract was entered into based on false information.
  • Waiver: The non-breaching party knowingly forgave the breach or accepted different performance.
  • Unclean Hands: The plaintiff also acted improperly in the matter at hand.

Defendants use these arguments to challenge the enforceability of the contract or the plaintiff’s right to recover damages.

Evidence Needed for Proving Breach of Contract

The success of a breach of contract claim often hinges on the strength of the evidence presented. Key types of evidence include:

  • The Contract Itself: A signed agreement or documentation of the terms, even in email or message form.
  • Communications: Emails, texts, or letters showing agreement to terms, performance expectations, and any notices of breach.
  • Proof of Performance: Invoices, receipts, timesheets, or delivery confirmations that show your compliance.
  • Proof of Breach: Records that the other party failed to act—such as missed deadlines, poor-quality work, or outright refusal to perform.
  • Damages: Documentation of financial losses, including repair costs, lost profits, or substitute service expenses.

Well-organized documentation strengthens your ability to prove all required elements of a breach claim in court.

Remedies Available in a Breach of Contract Case

Once a breach is proven, courts may award one or more of the following remedies, depending on the type and impact of the breach:

  • Compensatory Damages: Financial compensation to restore the injured party to the position they would have been in had the breach not occurred.
  • Consequential Damages: Additional losses caused by the breach that were foreseeable at the time of the contract.
  • Specific Performance: A court order requiring the breaching party to fulfill their contractual obligations, typically used when damages are insufficient (e.g., real estate).
  • Rescission: Cancels the contract, returning both parties to their pre-contract position.
  • Restitution: Requires the breaching party to return any benefit they received from the other party.

These remedies aim to ensure fairness and accountability when a party fails to uphold their contractual duties.

Frequently Asked Questions

1. What is the most important element in proving breach of contract? All four elements are critical, but proving the existence of a valid contract and actual damages caused by the breach is often most decisive.

2. Can I sue for breach of contract without a written agreement? Yes, but proving the terms and enforceability of an oral contract is more difficult. Supporting evidence like emails and payment records becomes crucial.

3. How long do I have to file a breach of contract claim? The statute of limitations varies by state—typically between 3 and 6 years for written contracts. Check local laws or consult an attorney.

4. What happens if both parties breached the contract? A court may determine the party that committed the “first material breach” and limit their ability to enforce the contract or recover damages.

5. Do I need an attorney to sue for breach of contract? While not legally required, an attorney can help assess your case, gather evidence, and improve your chances of success in court.
