What Is the Duty to Mitigate in a Personal Injury Case?

The duty to mitigate means an injured person has to take reasonable steps to keep their injuries and losses from getting worse. That includes getting prompt medical care and following the doctor's orders. New York uses a "reasonably prudent person" standard here. If you fail to take those steps, it can reduce the money a court or insurer pays you. It does not wipe out your claim.

This idea is sometimes called the doctrine of "avoidable consequences." It runs quietly through nearly every personal injury claim in New York. It does not decide who caused the accident. Instead, it looks at what the injured person did afterward. The question is whether reasonable choices about treatment and recovery would have limited the harm. This matters because insurance companies use it all the time to argue for a smaller payout, even when the defendant was clearly at fault.

Below, we explain the standard New York courts actually apply. We cover what "reasonable steps" look like in real life, where the duty ends, and how insurers try to turn it against injured people.

The Legal Standard in New York

New York courts define the duty to mitigate through a pattern jury instruction, PJI 2:325. In plain terms, it tells a jury that an injured person cannot recover for losses they could have avoided by using means a reasonably prudent person would have used to cure the injury or ease the pain. The bar is reasonableness. It is not perfection, and it is not what a doctor might call the ideal choice in hindsight.

The broader idea is simple. As the Cornell Law School Legal Information Institute puts it, the duty to mitigate is "a party's obligation to make reasonable efforts to limit the harm they suffer from another party's actions." In a personal injury case, that harm is the bodily injury and its money costs. The reasonable efforts usually mean getting and continuing the right medical treatment.

Two parts of this rule are often misunderstood, and both help the injured person.

Failure to mitigate is an affirmative defense. The injured person does not have to prove they did everything right. Instead, the defendant carries the burden here. That is almost always the defendant's insurance company. It has to prove that you acted unreasonably and that this conduct actually increased the damages. If the insurer cannot meet that burden, the argument fails.

Mitigation is not the same as comparative negligence. These two ideas are easy to mix up, but they answer different questions. Comparative negligence, governed by New York CPLR § 1411, is about fault for causing the accident. Think of a pedestrian who stepped into traffic against the light. Under New York's pure comparative negligence rule, your recovery drops by your share of fault for the accident, even if that share is large. The duty to mitigate has nothing to do with how the accident happened. It looks only at what you did after the injury and whether that made the harm worse. (We cover the accident-causation side in our post on comparative negligence.)

A defendant can raise both arguments in the same case. A jury weighs them separately. One cuts your recovery based on who caused the crash. The other is based on how you handled your recovery.

What "Reasonable Steps" Look Like in Practice

The standard turns on what a reasonably prudent person would do. So it helps to see what mitigation looks like in an ordinary injury claim. Reasonable steps usually include:

• Getting prompt medical treatment. Seeing a doctor soon after an accident protects your health. It also creates a clear record linking the injury to the event.
• Following your doctor's orders. This means going to physical therapy, keeping follow-up visits, taking prescribed medicine, and finishing the treatment rather than stopping partway.
• Returning to light-duty work when your doctor clears you. If a treating doctor releases you for lighter work, taking suitable light duty helps limit lost-wage claims.
• Avoiding activities that plainly make the injury worse. A reasonably prudent person with a broken ankle does not run a marathon on it against medical advice.

Keep in mind that the standard is reasonable, not extreme. No one has to undergo a risky or highly invasive procedure that a careful person in their shoes would decline. And no one has to go broke paying for care they cannot afford. The law asks whether your choices were sensible under the circumstances. It does not ask whether a more aggressive path might have worked out better.

Good records back up every one of these steps. Keep track of your appointments, your treatment, and how the injury affects your daily life. That makes it much harder for an insurer to claim you did not take recovery seriously.

The Legal Standard Is Objective: Williams v. Bright

The leading New York case on this point is Williams v. Bright, 230 A.D.2d 548 (2d Dep't 1997). A woman named Gwendolyn Robbins was injured in a car accident and suffered serious hip and knee damage. She was a Jehovah's Witness, and based on her sincere religious beliefs, she refused surgery that would have required a blood transfusion. At trial, the judge told the jury to decide whether Robbins acted reasonably "as a Jehovah's Witness," not whether a reasonably prudent person in her position would have accepted the surgery. The jury found for Robbins under that instruction.

The Appellate Division, Second Department, reversed. It held that swapping in a religion-specific "reasonable Jehovah's Witness" standard was legal error. The pattern jury instruction on mitigation calls for the objective "reasonably prudent person" test, and the trial court had no authority to replace it with a subjective, faith-based one. Because the jury never heard evidence about how widely held or how central her religious objection to transfusion actually was among Jehovah's Witnesses, it could not meaningfully apply even that alternate standard. The court sent the case back for a new trial on damages.

Williams v. Bright is important because of what it does not do: it does not carve out a special exemption from mitigation for religious refusals of treatment, or for any other personal characteristic. The reasonably prudent person standard stays objective. A plaintiff's religion, disability, or personal circumstances can still be relevant facts a jury considers in deciding what was reasonable for a person in that situation, but the legal test itself does not change person to person.

How Insurance Companies Use Failure-to-Mitigate Arguments

For insurers, the duty to mitigate is a tool to shrink payouts. Even when liability is not really in dispute, defense adjusters and lawyers hunt for gaps in the injured person's treatment history. Then they try to reframe those gaps as unreasonable conduct. Common tactics include:

• Pointing to delayed treatment to argue that the injury could not have been serious, or that some of the harm came from other causes.
• Highlighting skipped follow-ups or missed physical therapy to suggest the injured person did not really try to recover.
• Challenging lost-wage claims by arguing you refused suitable light-duty work your doctor had cleared you to do.

The goal of these arguments is a lower settlement offer. At trial, the goal is a smaller award from the jury. Here is the key protection worth repeating. Because failure to mitigate is an affirmative defense, the insurer has to prove two things. First, that the conduct was unreasonable. Second, that it actually increased the damages. A gap in treatment, by itself, proves nothing if there is a reasonable explanation. Maybe you had no transportation. Maybe you could not afford care. Maybe a flare-up made appointments impossible, or your own doctor told you to rest.

Common Mistakes That Undermine a Duty to Mitigate Defense

A few avoidable missteps give insurers an opening to raise a mitigation defense. The habits that protect a claim the most are:

1. Delaying treatment after an accident. Even a short, unexplained gap invites the argument that the injury was minor or unrelated.
2. Ignoring medical advice or missing appointments. Skipped therapy and no-shows are the most common basis for a failure-to-mitigate argument.
3. Refusing cleared light duty without a good reason. If a doctor releases you for suitable lighter work, turning it down without a real basis can hurt a lost-wage claim.
4. Using non-approved providers in a no-fault auto claim. New York's no-fault system has specific rules about covered treatment. Going outside them can create coverage gaps that look like a lapse in care.
5. Not telling your own attorney about changes in your condition. Your lawyer can only document and explain your recovery, including good reasons for any treatment gaps, if they know what is happening.

Most of these mistakes have reasonable explanations. The problem is that unexplained gaps look worse than they are. It falls to the injured person and their attorney to fill in the context.

What This Means for Your Claim

The practical takeaways are simple. Get treatment promptly. Keep your appointments. Follow the plan your doctor sets. And tell your attorney whenever your condition changes or you cannot follow through on care for a legitimate reason. Save the paperwork too: bills, discharge instructions, therapy schedules, and any notes explaining why you missed or delayed care.

When an insurer disputes whether you did enough to limit your injuries, an experienced attorney can gather the proof that your choices were reasonable. That means treating records, physician statements, and documentation of the real obstacles you faced. Because the insurer bears the burden on this issue, a well-documented claim leaves little room for a failure-to-mitigate argument to gain traction.

Related Questions

Does the duty to mitigate apply even if the accident wasn't my fault?

Yes. The duty to mitigate is separate from fault for the accident. Even when the other party is entirely to blame for your injury, you still have to take reasonable steps afterward to keep your damages from growing. Liability and mitigation are two different questions a jury considers on their own.

Can the insurance company reduce my settlement for failure to mitigate?

It can try, but it has to prove its case. Failure to mitigate is an affirmative defense, so the insurer carries the burden. It must show that you acted unreasonably and that your conduct actually increased your damages. If you have a reasonable explanation for a treatment gap, such as cost, transportation, or medical advice, the argument often fails.

Do I have to accept light-duty work to protect my personal injury claim?

Generally, yes, if a treating doctor clears you for suitable light-duty work and appropriate work is available. Taking it helps limit lost-wage claims. You are not required to take work that is unsuitable for your condition or that a doctor has not approved. The test is whether refusing was reasonable under your circumstances.

Can I refuse surgery and still recover full damages?

[QA note: this answer runs ~127 words, above the 35-75 word featured-snippet target, because it preserves the fact-checker's full corrected holding. Not shortened here to avoid reintroducing the original reversed-holding error — see QA report.]

What if I can't afford medical treatment after my accident?

An inability to pay for care is part of the circumstances a court weighs when deciding whether your conduct was reasonable. A genuine financial inability to get recommended treatment is not the same as unreasonably refusing it. Documenting the obstacle, and telling your attorney, helps rebut a failure-to-mitigate argument.
