New Hampshire Claims Dispute & Statutory Guide

New Hampshire operates an At-Fault automobile insurance framework under Title XXI and Title XXXVII of the New Hampshire Revised Statutes Annotated (RSA). Under RSA 264:16, whenever auto liability insurance is purchased, it must include at least $1,000 in Medical Payments (MedPay) coverage. Motor vehicle liability is governed by modified comparative fault with a 51% bar under RSA 507:7-d, and hospitals enforce statutory liens under RSA 448-A.

Statutory Framework & Jurisdiction

Applicable Legal System

At-Fault / Traditional Tort (Mandatory $1,000 MedPay When Insured & New Hampshire Hospital Lien Act)

New Hampshire is the only state that does not mandate purchase of auto liability insurance (operating under financial responsibility laws), but under RSA 264:16, if an automobile liability policy is issued, it must provide first-party Medical Payments (MedPay) coverage of at least $1,000 per person. Motor vehicle accident claims are governed by modified comparative fault under RSA 507:7-d, allowing recovery if the claimant's fault was not greater than the fault of the defendants. Hospitals secure unpaid inpatient and outpatient medical balances by asserting statutory liens under RSA Chapter 448-A.
