Whether an accident happened on a county road, in a small town or in one of the larger communities, the same New Hampshire rules apply: a 3-year filing deadline for most injury claims, modified comparative negligence (51% bar), and lawsuits filed in the Sullivan County Superior Court. This page is the county-wide guide, with links to a page for each community.

From 2020 through 2024, federal crash records list 17 fatal crashes in Sullivan County, in which 19 people died. Two roads had more than one: State Route 11 with 7 fatal crashes and State Route 12 with 5.

The yearly count was 4 in 2020, 2 in 2021, 9 in 2022, 1 in 2023 and 1 in 2024; 35% of the crashes happened after dark. 4 involved a pedestrian, cyclist or other person outside a vehicle, and 2 happened at or near an intersection.

Fatal crashes are the most serious outcome on these roads; many more crashes cause injuries without a death. Whatever the severity, the police crash report, photos of the scene and prompt medical records are the starting evidence for a claim.

Smaller communities in Sullivan County include Acworth, Cornish, Cornish Flat, Georges Mills, Goshen, Guild, Meriden, Plainfield, South Acworth, Washington. Residents of these areas follow the same New Hampshire rules, use the same Sullivan County Superior Court, and can request a free case review from anywhere in the county.

New Hampshire generally gives an injured person three years from the date of injury to file a personal injury lawsuit (RSA 508:4); medical malpractice is different (three years). Wrongful death claims follow their own deadline, which can differ from the one above. Claims against a city, county, school district or state agency follow separate and often much shorter deadlines. Once the deadline passes, the Sullivan County Superior Court will dismiss the case regardless of how clear the fault was, so the practical rule in Sullivan County is to get legal advice early.

New Hampshire follows modified comparative negligence (51% bar). In plain terms, you can recover as long as you were not more than 50% at fault, and your award is reduced by your share of fault. Insurance adjusters apply this rule from the first phone call, which is why the way an accident is described and documented in the days after it happens in Sullivan County has a direct effect on what a claim is worth.

After a crash in Sullivan County, the at-fault driver's liability insurance is the primary source of compensation. New Hampshire does not require drivers to buy auto insurance; a driver who causes a crash must instead show the ability to pay at least 25/50/25 (thousands of dollars for bodily injury per person, per accident, and property damage), which serious injuries quickly exhaust. Underinsured motorist coverage on your own policy and claims against additional responsible parties often make the difference in Sullivan County cases.

Lawsuits arising from accidents in Sullivan County are typically filed in the Sullivan County Superior Court, the trial court of general jurisdiction for Sullivan County, although cases can sometimes be filed where the defendant resides or does business, and claims against out-of-state trucking companies or manufacturers may end up in federal court. Most claims settle before trial, but the credible ability to try a case in Sullivan County is what moves insurers to pay fair value.

Employees injured on the job in Sullivan County are generally covered by New Hampshire workers' compensation, administered through the New Hampshire Department of Labor. Report the injury to your employer within 2 years (RSA 281-A:19) — a late report can delay or put the claim at risk, and the exceptions vary by state — then file the formal claim within three years. Workers' compensation does not pay for pain and suffering, so when a third party such as a subcontractor, driver or equipment manufacturer caused the injury, a separate personal injury claim is often worth pursuing alongside it.
