How Long Do I Have to File a New Hampshire Lemon Law Claim?
New Hampshire's deadlines — the one-year filing window (RSA 357-D:11), the 40-day hearing and 30-day decision, the narrow 30-day appeal, and the CPA and Magnuson-Moss clocks.
New Hampshire’s lemon-law deadline is to commence proceedings within one year after the warranty expires or after the last repair attempt. See the full statute of limitations guide.
The clocks
| Claim | Deadline | Runs from |
|---|---|---|
| Lemon Law RSA 357-D:11 | 1 year to commence | Warranty expiration or last repair attempt |
| Arbitration Board | Hearing in 40 days; decision in 30 days; appeal within 30 days | Filing the complaint |
| NH CPA | 3 years (RSA 508:4) | Accrual |
| Magnuson-Moss | 4 years | Tender of delivery |
How the lemon-law clock works
- Satisfy the presumption (3 attempts or 30 business days) within the warranty-plus-one-year protected period.
- Use the same dealer (or document good cause to switch).
- File with the Board within one year of warranty expiration or the last repair attempt.
Fast hearing, narrow appeal
The Arbitration Board holds a hearing within 40 days and decides within 30 days after; either side may appeal to Superior Court within 30 days — but on a narrow standard (no retrial), so the hearing is decisive.
When the CPA and Magnuson-Moss matter
The NH CPA runs 3 years (RSA 508:4) and Magnuson-Moss 4 years from delivery — both outlast the lemon law’s one-year filing window, making them useful fallbacks.
Bottom line
File with the Arbitration Board within one year of warranty expiration or the last repair attempt; the hearing follows in 40 days and a decision in 30. The CPA (3 years) and Magnuson-Moss (4 years) are the longer fallbacks. Get a free case review.
