New Hampshire security deposit law
Can I sue my landlord over my security deposit in New Hampshire?
The short answer
Yes. District Division — Small Claims in New Hampshire handles deposit disputes up to $10,000, no lawyer required. But send a formal demand letter first: it is the step judges expect, and it resolves most cases before filing.
You can, and New Hampshire makes it accessible: deposit disputes belong in District Division — Small Claims, which handles claims up to $10,000, filing fees are modest, and you represent yourself.
But suing first is usually the wrong order. Judges expect to see that you demanded the deposit in writing before filing, and a formal demand letter citing RSA § 540-A:7 resolves many disputes without a courtroom, faster and with no filing fee. The letter also builds your case file: certified-mail proof, a stated deadline, and an itemized amount are the exhibits that win small claims hearings.
What you can claim: the wrongfully withheld amount, plus up to 2x the deposit in statutory damages, plus attorney's fees where the statute allows, and court costs.
The practical sequence in New Hampshire: written forwarding address, statute-cited demand letter by certified mail with a 10 to 14 day response window, then file only if ignored. Bring the letter, the mail receipt, photos, and your lease. Cases with that file settle in hallways more often than they reach a judge.
The New Hampshire rules at a glance. Governing statute: RSA § 540-A:7. Return deadline: 30 days. Statutory damages: up to 2x the deposit for wrongful withholding. Attorney's fees: recoverable in qualifying cases. Court for disputes: District Division — Small Claims, claims up to $10,000.
