Meta Description:
Mitigation of damages is a core legal principle in contract and tort law, obligating the injured party to take reasonable steps to minimize their losses following a breach or wrongful act. Learn how this ‘duty to mitigate’ works, who bears the burden of proof, and how failure to act reasonably can reduce your recoverable compensation.
In the world of civil litigation, whether dealing with a complex breach of contract or a personal injury claim, the concept of compensation is central. However, a fundamental principle of fairness in law dictates that an injured party cannot simply sit back and watch their losses mount. This is the bedrock of the doctrine of Mitigation of Damages.
This principle, sometimes referred to as the doctrine of
The Core Principle: What is the “Duty to Mitigate”?
Mitigation of damages is a fundamental legal concept in both contract and tort law. It is the obligation placed upon a claimant to take reasonable efforts to minimize the harm or financial losses they suffer due to another party’s wrongful act or breach of contract.
Crucial Distinction: While commonly called the “duty to mitigate,” it is technically not an enforceable duty owed to the breaching party. Rather, it is a legal recognition that if the claimant fails to take reasonable steps, their damages recovery will be affected by that failure. The court will reduce the final compensation by the amount that
Application in Contract Law: The Business Context
In a breach of contract case, the injured party must make reasonable efforts to avoid further losses from the breach once they receive notice that the other party does not intend to perform. The overarching goal of contract law is to place the non-breaching party in the same situation they would have been in had no breach occurred.
Case Example: The Unnecessary Construction
A classic illustration is a construction contract scenario. If a county hires a company to build a bridge but later votes to abandon the project and informs the company to cease construction, the contractor has a duty to stop work. If the contractor continues construction and sues for the full contract price, the court will likely hold that the contractor cannot recover for the additional work performed after receiving the notice of breach, as those damages were avoidable. They must mitigate their loss.
Application in Tort and Employment Law
The duty to mitigate also applies broadly across tort law, including personal injury and employment disputes:
- Wrongful Termination: An employee who has been wrongfully terminated has a legal duty to make a diligent effort to find reasonably comparable employment. They cannot remain idle and accrue lost wages indefinitely. The employment sought must be
comparable work , defined by courts as a position affording “virtually identical promotional opportunities, compensation, job responsibilities, working conditions and status”. - Personal Injury: If an injury is sustained due to another’s negligence, the injured party is expected to seek reasonable and appropriate medical treatment in a timely manner. Failure to follow a medical expert’s reasonable recommendation may be argued by the defense as a failure to mitigate, potentially limiting recovery for any increased harm resulting from that inaction.
⚠️ Caution: The Reasonableness Standard
The claimant is not required to go to “heroic lengths” to mitigate their damages, nor are they required to take steps that would expose them to undue risk, burden, or humiliation. For example, a claimant is not generally required to undergo a significantly risky medical procedure. What is deemed “reasonable” is assessed on a case-by-case basis, taking all relevant circumstances into consideration.
The Burden of Proof: An Affirmative Defense
The principle of mitigation is central to litigation strategy because it acts as an
- Plaintiff’s Burden: The injured party (plaintiff) carries the initial burden of proving the defendant’s liability and the fact and quantum of the damages suffered.
- Defendant’s Burden: The party alleging a failure to mitigate (defendant) carries the entire burden of proof on this issue. They must prove by a preponderance of the evidence:
- That the plaintiff failed to make reasonable efforts to mitigate.
- That mitigation was possible and what steps the plaintiff should have taken.
- The extent to which the plaintiff’s damages could have been avoided had those reasonable steps been taken.
Legal Expert’s Tip: Document Everything
Because the burden of proof rests on the defendant to show a failure to mitigate, the injured party should proactively document all efforts made to minimize losses. This includes evidence of job applications, attempts to find substitute services or goods, and consistent adherence to a medical expert’s treatment plan. Demonstrating “good faith efforts” can strongly rebut any defense claim of failure to mitigate.
Impact on Damages Recovery
Failing to mitigate damages in contract law can significantly affect how much a non-breaching party can recover. The consequence is not a complete bar to recovery for the entire claim; instead, it is a reduction of the total award. The court will only award damages for losses that could not have been reasonably avoided.
The amount recoverable is often reduced by:
| Scenario | Mitigation Requirement | Damage Calculation Impact |
|---|---|---|
| Breach of Sales Contract | Buyer must seek a replacement supplier promptly. | The buyer recovers the difference between the contract price and the cost of the |
| Landlord-Tenant Lease Abandonment | Landlord must make reasonable efforts to re-rent the property. | The landlord’s damages are reduced by the rent they |
| Wrongful Dismissal | Employee must seek comparable new employment. | The employer’s liability for lost wages is offset by the wages the employee |
It is also important to note that the injured party is entitled to recover the reasonable and prudent expenses and other costs incurred in taking those necessary steps to mitigate, which are often classified as incidental damages.
Potential Exceptions and Limits
While the duty is nearly universal, there are limits and potential exceptions:
- Undue Risk or Expense: The claimant is not required to accept mitigation efforts that would expose them to undue risk or expense greater than the potential recovery. Financial inability to take a required mitigating action may sometimes be considered as a factor by the courts.
- Liquidated Damages Clause: If a contract includes an enforceable “liquidated damages” clause—which sets a pre-agreed amount of damages for a breach—a court is less likely to require mitigation, as the damages amount is already fixed by the parties’ agreement.
- Offer of New Contract: A plaintiff is not required to accept a new contract offered by the breaching party if accepting it would relinquish their rights under the original contract.
Summary of the Mitigation Principle
The duty to mitigate damages is an important layer of fairness in our legal system, balancing the right to compensation with the responsibility to act reasonably after suffering harm. By understanding its requirements, both claimants and defendants can better navigate the complexities of litigation.
Key Takeaways on Mitigation
- It is a Universal Principle: The duty to mitigate applies broadly across civil law, including breaches of contract, tort claims (like negligence and personal injury), and specific areas like landlord-tenant disputes and employment law.
- Act Reasonably, Not Perfectly: The claimant must make
reasonable efforts to minimize losses, which is a question of fact determined by the specific circumstances. They are not required to take heroic measures or incur undue risk. - The Burden of Proof is on the Defendant: Mitigation is an affirmative defense. The defendant must prove that the plaintiff failed to act reasonably and that the damages could have been avoided.
- Consequence is Reduction, Not Bar: A failure to mitigate does not entirely prevent recovery. It only prevents the recovery of the specific damages that could have been avoided by reasonable effort on the claimant’s part.
Summary Card: Mitigation of Damages

Legal Status: An affirmative defense; failure to comply reduces recoverable damages.
Proof: The party causing the harm (Defendant) must prove that the injured party (Plaintiff) failed to mitigate.
Action Required: Seek substitute performance, find new employment, or obtain necessary medical treatment.
Frequently Asked Questions (FAQ)
Q1: Is the “duty to mitigate” a strict legal duty I can be sued for?
No. It is a condition on your right to recover damages, not a duty in the sense of an obligation enforceable by the other party. You will not be sued for failing to mitigate, but the damages you recover will be reduced by any loss you could have reasonably avoided.
Q2: What if I cannot afford to take the required steps to mitigate my damages?
A claimant’s financial constraints may sometimes hinder their ability to mitigate. Courts have, in some instances, accepted a plaintiff’s lack of funding as a sufficient cause for failing to mitigate. However, this is heavily fact-dependent, and you must still demonstrate good faith efforts.
Q3: Does the mitigation principle apply to personal injury claims?
Yes. In personal injury cases, the injured party is expected to act reasonably, such as seeking timely medical treatment and following the advice of a medical expert. Failure to do so may lead to a reduction in damages for any injury aggravation that was avoidable.
Q4: Can a contract waive the duty to mitigate damages?
Generally, the duty is a default rule in most civil cases. However, parties may sometimes modify or effectively waive this duty in a written contract, often through an enforceable liquidated damages clause, which pre-sets the amount of damages.
Q5: How is “comparable employment” defined in wrongful termination cases?
In the employment context, the wrongfully terminated employee must seek comparable work, which is typically defined as a position offering “virtually identical promotional opportunities, compensation, job responsibilities, working conditions and status” to the previous job. They are not required to take a substantially inferior position.
