Step-by-Step: Suing a Cell Phone Company in New Hampshire
Confirm your claim is within New Hampshire's $10,000 limit
New Hampshire's small claims limit is $10,000. If your damages are higher, you can reduce your claim to the limit or file in New Hampshire civil court. Use our New Hampshire Small Claims Limit guide for the full details.
Send a demand letter first
File an FCC complaint at fcc.gov/consumers/guides/filing-informal-complaint first — carriers must respond to FCC complaints within 30 days, which often produces a resolution before you even file in court. Courts in New Hampshire expect plaintiffs to have made a good-faith attempt to resolve the dispute. A demand letter also creates a paper trail and often prompts payment without any court filing.
Gather your evidence
Your case is only as strong as your evidence. Collect everything before filing — see the checklist below for exactly what you need for a cell phone company dispute.
Find the right New Hampshire courthouse
File at the District Court in the New Hampshire county where the cell phone company is located, does business, or where the dispute occurred. For businesses, check the New Hampshire Secretary of State website for the correct legal name and registered agent address.
Pay the filing fee ($45–$95)
New Hampshire small claims filing fees range from $45 to $95 depending on your claim amount. Use our New Hampshire Filing Fee Calculator to find the exact amount for your claim. Keep your file-stamped copy.
Serve the defendant properly
The cell phone company must be formally notified of the lawsuit. New Hampshire courts provide specific instructions — follow them exactly. Improper service is one of the most common reasons cases are dismissed.
Present your case at the hearing
Bring 3 organized copies of all evidence. Present your case in order: what happened, how much you lost, and why the cell phone company is responsible. Most New Hampshire small claims hearings last 15–30 minutes. Stay calm, stick to facts, and let the judge ask questions.

Tips for Winning Your Cell Phone Company Case in New Hampshire
File an FCC complaint before going to court — it's free, carriers take them seriously, and it often resolves billing disputes without litigation.
Always get plan price promises in writing (chat transcript, email) — verbal promises from customer service are almost impossible to prove.
Cell carriers have arbitration clauses, but most allow small claims court as an exception — check your specific carrier's agreement.
Screenshot every chat conversation with customer service — they often don't send email confirmations.
