Suing a Neighbor for Property Damage in New Hampshire Small Claims Court
When Neighbor Damage Belongs in Small Claims
Property damage from a neighbor — a fallen tree that crushed your fence, water runoff that flooded your basement, excavation work that cracked your foundation — is a tort claim. If the damage is $10,000 or less, New Hampshire small claims court can handle it. Under RSA 508:4, the three-year limitations period generally starts when the injury occurred; if the injury and its cause were not and could not reasonably have been discovered then, it starts when they were discovered or reasonably should have been discovered.
One important limit: small claims court cannot order your neighbor to do something (trim a tree, fix a drainage problem, remove a structure). It can only award money damages. If you need an injunction, you need Superior Court.
Proving Your Claim
Neighbor property damage cases turn on two questions: did the neighbor cause the damage, and how much did it cost to fix?
For causation, document everything:
- Photographs of the damage, taken as soon as possible with timestamps. Include wide shots showing the relationship between the neighbor's property and yours, plus close-ups of the damage itself.
- Before-and-after comparisons if you have photos from before the incident (real estate listing photos, home insurance records, or your own pictures).
- Written estimates from licensed contractors or repair companies for the cost of restoration. Get at least two.
- Communications with the neighbor — texts, emails, or letters where they acknowledged the damage, offered to pay, or refused responsibility.
For tree damage specifically, the New Hampshire Supreme Court has held that a landowner who knows or should know a tree is decayed or defective and fails to maintain it reasonably may be liable for injuries proximately caused, including beyond the property line. A healthy tree that falls in a storm is harder to recover for — the claim turns on proof of a known or reasonably knowable defect and negligent maintenance.
The Demand Letter
Before filing, send a written demand by certified mail. State what happened, when it happened, the cost of repair (attach the estimates), and a deadline of 10 to 14 days to pay or propose a resolution. Many neighbor disputes settle at this stage because the alternative — a court date — concentrates minds.
Keep the tone factual, not hostile. You live next to this person, and the judge will notice if your correspondence was reasonable while the neighbor's was not.

Filing and Service
File through TurboCourt. The fee is $125 for claims up to $5,000 or $180 for claims from $5,001 to $10,000. File in the District Division court that has jurisdiction over the municipality where either you or the neighbor lives. If you live in different municipalities, either one's court location may be proper.
The court serves the complaint by first-class mail. Since your neighbor lives next door, mail service rarely fails, but if the court reports that it came back undeliverable, you have 60 days to provide a corrected address or file a motion requesting an Order of Notice for personal service by a sheriff or other authorized process server.
At the Hearing
Bring your photographs, repair estimates, the demand letter with proof of mailing, and any communications. If a contractor assessed the damage, ask them to attend as a witness or provide a signed written statement describing what they found.
The judge will want to see a clear chain: the neighbor's property (or the neighbor's action) caused the damage, you tried to resolve it, and the repair cost a specific amount. Avoid speculative claims like diminished property value unless you have an appraisal to back it up. Stick to actual repair costs.
