What the TDMV 12 is and why it matters
TDMV 12 is New Hampshire's Odometer Disclosure Statement. The state's title rule, Saf-C 1903.05, says when it's used: if an application for title or an assignment of title doesn't contain the current odometer reading, or a discrepancy is discovered, the seller completes a TDMV 12.
So it's a fallback. On a normal dealer sale the mileage goes in the title's assignment and in box 19 of the TDMV 23 title application. This guide walks every box on the TDMV 12, says who fills it on a dealer sale, and covers the related New Hampshire rules and the federal record rule.
The current revision is TDMV 12 (Rev. 03/23), the revision New Hampshire's title rule Saf-C 1903.05 names. It's a one-page PDF from the NH Division of Motor Vehicles. The state's PDF has typeable fields, but it's encrypted, and DealerVLO's form uploader can't open it. Type it in a PDF reader or fill it by hand. The DMV's site may block automated downloads; it opens normally in a browser.
Documents to have before you start
Gather these before you complete the TDMV 12. A missing attachment is the number-one reason the the New Hampshire Department of Safety, Division of Motor Vehicles bounces a title application back.
- The title being assigned — Saf-C 1903.02 says the assignment on the back must carry the buyer's name and address, the odometer reading in actual mileage, and the seller's signature and printed name.
- The TDMV 23 title application — Box 19 is the mileage. It should match the TDMV 12. See the TDMV 23 guide.
- TDMV 17A, if every dealer assignment space on the title is used — Saf-C 1903.03. That form carries its own odometer certification.
TDMV 12, section by section
When a New Hampshire dealer needs the TDMV 12
Saf-C 1903.05 covers two cases: the application for title or assignment of title doesn't contain the current odometer reading, or a discrepancy is discovered. Other NH forms already carry the certification. Saf-C 1903.03 says the TDMV 17A, the Registered Owner's Assignment / Dealer's Reassignment of Title, is used when all dealer assignment space on the title is used, and the seller certifies the reading on it. Saf-C 1903.04 says the same for the TDMV 25A pending title and payoff form. New Hampshire doesn't title vehicles of model year 1999 or older, according to the DMV's title FAQ. And the federal rule exempts model year 2010 and older, model year 2011 and newer once they're 20 years old, and vehicles over 16,000 pounds GVWR (49 CFR 580.17).
| Field | Who fills it |
|---|---|
Title assignment with the current reading No TDMV 12. | You (dealer) |
Title application or assignment without the current reading Seller completes a TDMV 12. | You (dealer) |
Mileage discrepancy discovered Seller completes a TDMV 12. | You (dealer) |
Dealer assignment spaces used up TDMV 17A, which has its own odometer certification. | You (dealer) |
The seller's certification
The first line reads "I, (seller's printed name) certify that, to the best of my knowledge, this odometer reading is ___." On a retail sale the seller is your dealership. Then check one: ACTUAL MILEAGE, EXCEEDS MECHANICAL LIMITS (the form explains: odometer started over at zero), or NOT THE ACTUAL MILEAGE, WARNING — ODOMETER DISCREPANCY. Under Saf-C 1903.05(b), signing the form certifies the reading and which of the three it is. The form doesn't say no tenths, but the federal rule does (49 CFR 580.5).
| Field | Who fills it |
|---|---|
Seller's printed name | You (dealer) |
Odometer reading No tenths. | You (dealer) |
Actual mileage Check one of three. | You (dealer) |
Exceeds mechanical limits (odometer started over at zero) | You (dealer) |
Not the actual mileage. Warning — odometer discrepancy | You (dealer) |
Vehicle and date of statement
Below the certification is a row for the VIN (17 boxes, one character each), year, make and body. There's no separate model box. Then the date of statement. Copy the vehicle from the title.
| Field | Who fills it |
|---|---|
Vehicle Identification Number (VIN) One character per box. | You (dealer) |
Year | You (dealer) |
Make | You (dealer) |
Body | You (dealer) |
Date of statement | You (dealer) |
Buyer's name, address and acknowledgement
The buyer's printed name, then street, city, state and ZIP. The buyer signs under the line "I am aware of the above odometer certification made by the seller." New Hampshire's other title forms describe the same step: the buyer certifies they've been made aware of the seller's odometer certification.
| Field | Who fills it |
|---|---|
Buyer's name (printed name) | Buyer |
Street, city, state, ZIP code | Buyer |
Buyer's signature Ink. | Buyer |
Seller's name, address and signature
The last block is the seller: printed name, street, city, state and ZIP, and the seller's signature. On a retail sale that's your dealership, signed by an authorized person. The form has no dealer number box; your dealer number goes in box 18 of the TDMV 23.
| Field | Who fills it |
|---|---|
Seller's name (printed name) | You (dealer) |
Street, city, state, ZIP code | You (dealer) |
Seller's signature Ink. | You (dealer) |
Penalties and the 5-year rule
The form's header warns that federal law (and state law, if applicable) requires the mileage to be stated on transfer, and that failing to complete it or giving a false statement may mean fines or imprisonment. The form doesn't cover record keeping. The federal rule does: a dealer keeps a copy of every odometer statement it issues and receives for five years (49 CFR 580.8).
| Field | Who fills it |
|---|---|
Copy of every statement issued and received, kept 5 years | You (dealer) |
Common TDMV 12 mistakes that cause rejections
Saf-C 1903.03 sends that case to the TDMV 17A, which carries its own odometer certification.
Saf-C 1903.02 says the assignment must include the odometer reading in actual mileage. Complete it at the sale.
Box 19 on the title application and the TDMV 12 should show the same number.
The form says check one.
The buyer signs to acknowledge the seller's certification. Get it before the buyer leaves.
Common questions
Where do I get a New Hampshire odometer disclosure statement?+
The NH DMV lists it as Form TDMV 12 on its forms page at dmv.nh.gov. The current revision is 03/23. The download button at the top of this guide links straight to it.
When is a TDMV 12 required in New Hampshire?+
Saf-C 1903.05 says the seller completes one when an application for title or assignment of title doesn't contain the current odometer reading, or when a discrepancy is discovered.
Do I need a TDMV 12 if the title assignment has the mileage?+
No. The assignment on the back of the title carries the reading (Saf-C 1903.02), and the TDMV 12 is for when it doesn't or there's a discrepancy.
Which vehicles are exempt from odometer disclosure in New Hampshire?+
Under the federal rule (49 CFR 580.17): model year 2010 and older, model year 2011 and newer once they're 20 years old, vehicles over 16,000 pounds GVWR, vehicles that aren't self-propelled, and new vehicles moving between dealers before the first retail sale. New Hampshire also doesn't title vehicles of model year 1999 or older.
Does the TDMV 12 need a notary?+
The form has no notary block. The seller signs to certify the reading and the buyer signs to acknowledge it.
How long do New Hampshire dealers keep odometer statements?+
Five years, under the federal rule (49 CFR 580.8): a copy of every odometer statement you issue and receive.
Is there software that fills out the TDMV 12 automatically?+
Not this one. The New Hampshire TDMV 12 is an encrypted state PDF that DealerVLO's form uploader can't open, so it's completed by hand and signed in ink. Dealer management software like DealerVLO handles the paperwork around it from the deal you already entered: a print-ready New Hampshire TDMV 23 title-application worksheet, the Bill of Sale, the FTC Buyers Guide, and the odometer disclosure, so the TDMV 12 is the only page left to write. It's $29/month flat with a 14-day free trial.
