New Hampshire Statute of Limitations by Case Type

New Hampshire's statutes of limitations establish mandatory filing deadlines that govern civil and criminal proceedings across the state court system. These deadlines are codified primarily within the New Hampshire Revised Statutes Annotated (RSA), Title LV (Proceedings in Special Cases) and Title LX (Administration of the Law). Missing a filing deadline extinguishes the right to pursue a claim, regardless of its underlying merit, making the identification of the correct limitation period a threshold requirement in any case evaluation.

Definition and Scope

A statute of limitations is a legislative enactment specifying the maximum period within which a party may initiate legal proceedings after the event giving rise to the cause of action. In New Hampshire, these periods are established by the state legislature under RSA Chapter 508 (Limitation of Actions) and related chapters addressing specific subject areas such as medical malpractice (RSA 507-C), product liability, and criminal prosecution (RSA 625:8).

The limitation period begins running at a defined trigger point — typically the date of injury, breach, discovery, or accrual — and runs continuously unless a recognized tolling condition interrupts it. The New Hampshire Supreme Court has interpreted the accrual date in various case categories, particularly in discovery-rule contexts, providing binding precedent that practitioners reference alongside the statutory text.

Scope and Coverage: This page applies exclusively to proceedings governed by New Hampshire state law, filed in New Hampshire state courts or federal courts applying New Hampshire substantive law under diversity jurisdiction. Federal causes of action filed in the United States District Court for the District of New Hampshire carry their own federal limitation periods under 28 U.S.C. § 1658 or applicable federal statutes and are not covered here. Claims governed by tribal law, military law, or the law of another state fall outside the scope of RSA Chapter 508. For the broader regulatory context for the New Hampshire legal system, the interplay between state and federal jurisdiction is addressed separately.

Core Mechanics or Structure

New Hampshire limitation statutes function through three core structural elements: the accrual rule, the tolling doctrine, and the repose period.

Accrual Rule: The clock begins when the cause of action "accrues." For most tort claims, RSA 508:4 sets a general 3-year limitation period, with accrual beginning on the date of the act or omission causing the injury. However, the discovery rule — adopted by the New Hampshire Supreme Court and codified in RSA 508:4, II — provides that the period does not begin until the plaintiff discovers, or reasonably should have discovered, the injury and its causal connection to the defendant's conduct.

Tolling Doctrine: RSA 508:7 and RSA 508:8 suspend the running of the clock in defined circumstances. RSA 508:7 tolls the period when the plaintiff is a minor (under age 18) or is of "unsound mind" at the time the cause of action accrues. RSA 508:8 provides tolling when the defendant is absent from the state or conceals assets. The New Hampshire Legislature has also enacted specific tolling provisions in the context of New Hampshire domestic violence legal protections, recognizing coercion as an impediment to timely filing.

Statutes of Repose: Distinct from limitation periods, statutes of repose set an outer time boundary measured from the defendant's act — not the plaintiff's discovery. RSA 507-C:4 establishes a 6-year repose period in medical injury actions, after which no claim may be brought regardless of when the injury was discovered.

Causal Relationships or Drivers

Legislative policy choices shape limitation periods across case types. Three primary drivers account for the variation in periods across RSA chapters:

Evidence Preservation: Shorter limitation periods in commercial and contract disputes (3 years under RSA 382-A:2-725 for UCC sales contracts, measured from breach rather than discovery) reflect the policy that commercial parties maintain business records for defined retention windows. The New Hampshire contract law framework treats certainty of deadlines as essential to commercial predictability.

Injury Severity and Latency: Personal injury and toxic tort cases involving latent conditions — such as asbestosis or occupational disease — require longer or discovery-triggered periods because injuries may not manifest for decades. RSA 507-B:7 addresses latent injury accrual in product liability contexts under New Hampshire tort law.

Public Policy for Specific Defendants: Claims against governmental entities in New Hampshire are subject to notice requirements under RSA 507-B (governmental immunity) and shorter pre-suit notice windows — 60 days for personal injury claims against municipalities under RSA 507-B:7 — before the standard limitation period even begins to matter. This shorter window reflects legislative balancing of taxpayer protection against individual claimant rights.

Classification Boundaries

New Hampshire limitation periods divide into four primary classification categories:

General Civil Claims: RSA 508:4 establishes the baseline 3-year period applicable to personal injury, property damage, and most tort actions not otherwise specified.

Contract Claims: Written contracts carry a 3-year limitation period under RSA 508:4. UCC-governed sales contracts are controlled by RSA 382-A:2-725, which sets a 4-year period measured from breach. Oral contracts follow the same 3-year general rule unless a specific statute applies.

Specialized Tort Actions: Medical malpractice claims are governed by RSA 507-C:4, establishing a 3-year period from discovery (with the 6-year repose outer limit). Libel and slander claims carry a 3-year period under RSA 508:4. New Hampshire employment law claims under RSA 275 (wage and hour violations) carry a 2-year limitation period for willful violations, consistent with the parallel federal Fair Labor Standards Act structure.

Criminal Prosecution: Under RSA 625:8, murder has no limitation period. Felonies not otherwise specified carry a 6-year period. Class A misdemeanors carry a 6-year period; Class B misdemeanors and violations carry a 1-year period. Sexual assault offenses involving minors under RSA 625:8, III(g) carry extended periods — prosecution may commence within 22 years of the victim's 18th birthday for certain offenses, as set by RSA 625:8, III(g). The New Hampshire criminal procedure system processes these criminal limitation questions through the Superior Court and Circuit Court as applicable.

Property and Probate: Real property adverse possession claims require 20 years of continuous possession under RSA 508:2. Actions to recover personal property carry a 6-year period. Probate claims under New Hampshire probate law are governed by RSA 556:5, which imposes a 1-year limitation on claims against a decedent's estate from the date of the administrator's appointment notice.

Tradeoffs and Tensions

The limitation framework presents three areas of operational tension within New Hampshire practice.

Discovery Rule vs. Certainty: Applying the discovery rule to personal injury claims creates unpredictable exposure windows for defendants, particularly in cases involving latent occupational disease or childhood sexual abuse. Defendants face the prospect of claims arising 20 or more years after conduct occurred, while plaintiffs argue that strict accrual from the date of act would extinguish legitimate claims before the injured party could reasonably know they existed.

Governmental Notice Requirements vs. Individual Rights: The 60-day pre-suit notice requirement for claims against municipalities under RSA 507-B:7 creates a compressed window that operates independently of — and prior to — the standard limitation clock. A claimant who files a timely lawsuit but failed to provide the 60-day notice faces dismissal. This asymmetry disproportionately affects self-represented litigants navigating the system without counsel, a tension examined in discussions of New Hampshire legal self-representation.

Criminal Limitations and Cold Cases: Extended limitation periods for sexual offenses involving minors reflect legislative response to documented underreporting patterns. Critics argue that extended periods create evidence-quality problems for defendants; proponents point to DNA and digital evidence preservation as mitigating the traditional rationale for short criminal limitation periods.

Common Misconceptions

Misconception 1: Filing a police report or administrative complaint tolls the civil limitation period.
Filing a complaint with the New Hampshire Commission for Human Rights or a similar agency does not automatically toll the civil court limitation period under RSA 508:4. The two tracks operate independently unless a specific statute provides cross-system tolling.

Misconception 2: The discovery rule extends the limitation period indefinitely.
RSA 507-C:4's 6-year repose period applies to medical injury actions regardless of discovery. Even if a patient discovers a surgical error at year 7, the repose period has already extinguished the claim.

Misconception 3: A written contract always carries a longer period than an oral contract.
In New Hampshire, both written and oral contracts fall under the same 3-year period under RSA 508:4. The UCC's 4-year period under RSA 382-A:2-725 applies only to contracts for the sale of goods, not service contracts or mixed contracts.

Misconception 4: Minority tolling continues until the minor turns 21.
RSA 508:7 tolls the period until the minor reaches age 18, after which the standard limitation period begins running. The tolling period does not extend beyond majority to age 21.

Misconception 5: Statutes of limitations and statutes of repose are interchangeable terms.
They are legally distinct. Limitation periods are subject to tolling; repose periods generally are not. New Hampshire courts have treated RSA 507-C:4's repose provision as a substantive right, not merely a procedural bar, making it more resistant to equitable tolling arguments.

Checklist or Steps

The following sequence reflects the structural process for identifying the operative limitation period in a New Hampshire civil case. This is a reference framework, not legal advice.

  1. Identify the cause of action — Classify the claim as tort, contract, property, probate, employment, or a specialized statutory claim.
  2. Locate the controlling statute — Consult RSA Chapter 508 (general), RSA 507-C (medical injury), RSA 382-A:2-725 (UCC sales), RSA 507-B (governmental liability), or the specific enabling statute for regulatory claims.
  3. Determine the accrual trigger — Establish whether accrual is event-based (date of breach, date of injury) or discovery-based under RSA 508:4, II.
  4. Check for applicable repose periods — In medical malpractice cases, confirm whether the 6-year repose period under RSA 507-C:4 has expired before evaluating whether the discovery rule applies.
  5. Identify tolling conditions — Review RSA 508:7 (minority, unsound mind) and RSA 508:8 (defendant's absence or concealment) to determine whether any condition suspended the running of the clock.
  6. Check pre-suit notice requirements — For claims against municipalities or the state, confirm whether RSA 507-B notice requirements apply and whether the 60-day window was met.
  7. Confirm criminal limitation periods separately — Criminal prosecution deadlines under RSA 625:8 are determined independently of any related civil claim and are controlled by the offense classification.
  8. Account for federal claim periods — If the claim involves a parallel federal cause of action filed in federal courts in New Hampshire, identify the separate federal limitation period, which may differ.
  9. Cross-reference administrative agency deadlines — Regulatory claims through the New Hampshire Department of Labor or the Commission for Human Rights carry independent filing windows that operate on different tracks from RSA Chapter 508.
  10. Document the calculation — Record the accrual date, applicable period, tolling periods (if any), and final deadline in writing, referencing the specific RSA provision for each element.
