New Hampshire Personal Injury Laws 2026

Statute of Limitations: RSA 508:4

Injured in Manchester, Portsmouth, or anywhere across the Granite State? You have three years from the date of injury to file a personal injury lawsuit in New Hampshire court. That deadline is set by RSA 508:4, the general personal actions statute, and it applies to most tort claims — slip-and-fall accidents, car crashes, dog bites, premises liability, and similar matters.

Miss the three-year window and New Hampshire courts will almost certainly dismiss your case on procedural grounds, regardless of how strong your underlying claim might be. Defendants routinely move to dismiss on limitations grounds at the earliest opportunity, so the deadline is real and strict.

The Discovery Rule

RSA 508:4 includes a codified discovery rule. The three-year period does not begin to run until two prongs are both satisfied: the plaintiff knew or reasonably should have known that an injury occurred, and the plaintiff knew or reasonably should have known that the injury was caused by the defendant's conduct. This matters most in cases involving latent conditions — toxic exposure, medical implants, or occupational disease — where the connection between an act and an injury may not surface for years.

Claims Against Government Entities

Suing a New Hampshire municipality — a city, town, or county — adds an extra layer. RSA 507-B governs claims against governmental units, and it imposes a 60-day written notice requirement from the date of injury. While failure to give timely notice does not automatically doom a claim — the municipality must show it was "substantially prejudiced" by the lack of notice — the safer practice is to serve the notice immediately after an accident involving a government entity. Claims against state agencies carry their own procedural requirements, so confirm the proper channel with an attorney before any deadline passes.

Tolling for Minors

Children injured in New Hampshire do not lose their right to sue just because a parent fails to act within three years. The statute is tolled until the minor turns 18, at which point the three-year clock begins. An 8-year-old hurt in a Concord playground accident therefore has until age 21 to file. Parents who act on a child's behalf before that point can bring a claim sooner, but the child's independent right remains preserved.

Three years sounds like ample time, but evidence disappears, witnesses forget details, and accident scenes change. Getting in front of an attorney well before that deadline — and certainly within the first year — gives you the best foundation for a strong case.

Modified Comparative Fault: RSA 507:7-d

New Hampshire follows modified comparative negligence with a 51% bar, codified at RSA 507:7-d. The system recognizes that accidents are rarely the product of a single actor's carelessness — a plaintiff who shares some blame can still recover, but only within limits.

How the 51% Bar Works

After a New Hampshire personal injury trial, the jury assigns a fault percentage to every party — plaintiff, defendant, and any third parties the defendant names. The plaintiff's share of fault is then tested against the 51% threshold:

• If the plaintiff is 50% or less at fault, recovery is allowed — but the damages award is reduced by that percentage. A $100,000 verdict with a 30% fault finding becomes a $70,000 judgment.
• If the plaintiff is 51% or more at fault, the plaintiff is completely barred from any recovery, regardless of how serious the injury.

The statute uses a combined comparison approach when multiple defendants are involved. A plaintiff is barred only if their fault exceeds the fault of all defendants in the aggregate. This means a plaintiff found 40% at fault in a two-defendant case where the defendants together carry 60% of the blame can still recover — though the award is reduced by the plaintiff's 40% share accordingly.

Apportionment and Several Liability

New Hampshire largely abolished traditional joint and several liability through RSA 507:7-e. In most cases each defendant is liable only for their own proportionate share of the damages — a defendant found 20% at fault pays 20% of the verdict, not the full amount. One important exception: defendants who knowingly pursued a common plan or design that caused the harm remain jointly and severally liable. If a defendant's share proves uncollectible, the court can reallocate that amount among the remaining defendants on motion filed within 60 days of final judgment.

For Granite State plaintiffs, the practical lesson is clear: every statement you make after an accident — to police, insurers, and opposing counsel — can be used to push your fault percentage toward or past the 51% cutoff. Careful documentation and prompt legal representation matter from day one.

No Damage Caps in New Hampshire

New Hampshire is one of the few states where statutory caps on personal injury damages have been consistently held unconstitutional. The source of that protection is Part I, Article 14 of the New Hampshire Constitution, which guarantees every person a remedy for injuries sustained. The state Supreme Court has treated this provision as a meaningful check on legislative attempts to limit the size of jury awards.

The Landmark Cases

In Carson v. Maurer, 120 N.H. 925 (1980), the New Hampshire Supreme Court unanimously struck down the legislature's medical malpractice damage cap. The court held that the statute denied med-mal plaintiffs equal protection under the state constitution — an injured patient could not constitutionally be treated differently from other tort claimants simply because the defendant happened to be a doctor or hospital.

A decade later, in Brannigan v. Usitalo, 134 N.H. 50 (1991), the court applied the same reasoning to a broader statute that capped noneconomic damages at $875,000 in all personal injury cases. That cap, too, fell. The statutes technically remain on the books, but they carry no legal force — courts will not apply them, and defendants cannot invoke them to limit a jury award.

What This Means in Practice

A Nashua plaintiff who suffers a spinal cord injury and needs lifetime care is not subject to an artificial ceiling on what a jury may award for pain and suffering, loss of enjoyment of life, or future medical needs. Serious, permanent injuries can produce substantial verdicts in New Hampshire that might be sharply curtailed in a cap state. That said, uncapped potential also means litigation is more fiercely contested — defendants in New Hampshire have strong financial incentives to fight hard on liability and damages.

Punitive Damages: The Important Exception

New Hampshire's generosity does not extend to punitive damages. RSA 507:16 states plainly that "No punitive damages shall be awarded in any action." The legislature's position is that punishment belongs in the criminal system, not civil courts.

However, New Hampshire courts recognize a doctrine of enhanced compensatory damages as a limited substitute. When a defendant's conduct was wanton, malicious, or oppressive, a jury may be instructed to double the compensatory damages. Enhanced damages are rare — they require a high threshold of egregious misconduct — but they exist and have been awarded. They are not the same as punitive damages, remain compensatory in character, and are themselves subject to constitutional scrutiny.

New Hampshire's Unique Auto Insurance System

Here is the fact that surprises most people: New Hampshire is the only state in the country that does not require drivers to carry automobile insurance. Every other state and the District of Columbia mandates at least some minimum liability coverage. New Hampshire stands alone — a product of the state's deep libertarian streak and its longstanding skepticism of government mandates.

Financial Responsibility, Not Mandatory Insurance

What New Hampshire requires instead is financial responsibility — the demonstrated ability to pay for damages you cause. Under RSA 264 (Accidents and Financial Responsibility), drivers who choose not to carry insurance must be able to show they can cover at least $25,000 per person / $50,000 per accident for bodily injury, and $25,000 for property damage through an acceptable alternative: a surety bond from a licensed bonding company, or a $50,000 cash deposit with the New Hampshire Department of Safety.

In practice, the overwhelming majority of New Hampshire drivers carry standard auto insurance policies because it is far simpler and often less expensive than posting a $50,000 cash deposit. But nothing in state law compels them to do so before they get behind the wheel.

What Happens After an Accident

If you are in an accident and the at-fault driver has no insurance and no alternative proof of financial responsibility, that driver faces license and registration suspension under RSA 264:3 until they post security covering the full amount of damages. That suspension does not put money in your pocket, and collecting on an uninsured, asset-poor driver through a civil judgment can be a long and fruitless endeavor.

Why UM/UIM Coverage Is Especially Critical in New Hampshire

In states where insurance is mandatory, an uninsured driver is an outlier who broke the law. In New Hampshire, an uninsured driver may simply be someone who never purchased a policy and faces no legal penalty for it. The pool of drivers who can pay out of pocket for serious injury damages is small, while the pool of uninsured drivers without meaningful assets is considerably larger.

If you carry a New Hampshire auto policy and are hit by an uninsured driver, the UM/UIM claim process works like this: you file a claim with your own insurer, your insurer steps into the shoes of the at-fault driver, and your damages are evaluated against your policy limits. New Hampshire law sets minimum UM/UIM limits at $25,000 per person / $50,000 per accident — identical to the bodily injury minimums — but purchasing higher limits is wise. A serious traumatic brain injury or spinal injury will exhaust minimum limits quickly.

Practical Implications for Injury Victims

If you are injured by a driver on Route 3 in Concord or I-93 near Manchester and that driver lacks insurance or assets, your options narrow considerably. You can pursue a civil judgment, but collecting on it is another matter entirely. The better protection is proactive: carry robust UM/UIM coverage, add MedPay coverage to your policy, and understand what you have before an accident happens — not after. An attorney experienced with New Hampshire's financial responsibility framework can also help you identify whether any other parties share liability and whether any additional insurance policies might apply to your claim.
