To transfer a vehicle, the seller signs the back of the title in the block labeled “Assignment of Title by Owner,” the buyer signs the separate buyer’s block next to it, and both parties sign the odometer disclosure area. Knowing where to sign a vehicle title is only half the job: the exact line, the ink color, and whether a co-owner or notary also needs to sign all decide whether your motor vehicle office accepts the transfer or sends you home for a duplicate.
The Seller’s Assignment Section
Flip the title over. Look for the area labeled “Assignment of Title by Owner” or similar wording. That block holds a signature line, a space to print your full legal name, and a field for the date of sale. Your signature has to match the name printed on the front of the title. If the front reads “Robert J. Smith,” signing as “Bob Smith” is grounds for rejection.
The seller also fills in the buyer’s full name, the sale price, and the buyer’s mailing address inside this same assignment area. Write slowly. Whatever name you write on the buyer line is the name the motor vehicle office will use to issue the next title, and fixing it afterward is a separate process.
Co-Owners: “And” Versus “Or”
Before anyone picks up a pen, check the conjunction between the owners’ names on the front of the title.
If the names are joined by “and,” both owners must sign the seller’s assignment section. One signature alone will not transfer the vehicle. If the names are joined by “or” or “and/or,” either owner can sign independently and complete the sale without the other. The distinction matters most during divorces or when co-owners live apart.
The Odometer Disclosure Block
Federal law requires the seller to record the vehicle’s current mileage on the title at the moment of transfer. The odometer disclosure block sits near the seller’s assignment area and needs signatures from both the seller and the buyer. The seller signs to certify the mileage; the buyer signs to acknowledge receiving the disclosure.
The seller also has to check a box indicating whether the mileage reading is accurate, whether the odometer has exceeded its mechanical limit, or whether the actual mileage is unknown. Both parties print their names and current addresses in this block as well.
One useful quirk: when a vehicle has multiple owners, only one of them has to sign the odometer disclosure, even if the title uses “and” between the names.1eCFR. 49 CFR 580.5 – Disclosure of Odometer Information That is the opposite of the assignment section, where every “and” co-owner has to sign. The federal regulation lets a single transferor handle the odometer statement for all owners.
Older Vehicles Are Exempt
Not every sale needs an odometer entry. Federal regulations exempt vehicles by age. For transfers in 2026, any vehicle with a model year of 2010 or older is exempt and uses a 10-year window. Vehicles from model year 2011 onward sit under a longer 20-year window, so a 2011 model will not become exempt until 2031.2eCFR. 49 CFR 580.17 – Exemptions If the car qualifies, you can leave the odometer section blank.
Odometer Fraud Is a Federal Offense
Rolling back or misstating the mileage carries civil penalties and, for willful tampering, criminal penalties including up to three years in prison.3Office of the Law Revision Counsel. 49 USC 32709 – Penalties and Enforcement Record what the odometer actually shows. If you suspect the reading is wrong, check the “actual mileage unknown” box rather than guess.
The Buyer’s Signature Section
The buyer has a separate labeled block, usually directly below or beside the seller’s assignment area. Sign your name, print it, enter your current address, and write the purchase date. Some titles also ask for the buyer’s driver’s license number. Fill every field that applies. Blank fields are one of the most common reasons title applications get rejected at the counter.
If two people are buying together, pay attention to how you list both names. “And” means both owners will have to sign next time the vehicle is sold. “Or” lets either owner transfer the vehicle independently later on. The choice you make here will shape every future transaction involving this title.
The Lien Release Line
If the vehicle had a loan against it, the front of the title shows a lienholder. Before the seller can transfer anything, that lien has to be satisfied, and the lienholder signs a designated release line on the title confirming the payoff. Without that release signature, the buyer cannot get a clean title in their name.
The release usually happens before the sale. The seller pays off the balance, the lender either signs the title directly or sends a separate lien release document, and the sale proceeds. If you are the buyer and the title still shows an active lien with no release signature, do not pay until the seller clears it. A title with an uncleared lien is locked.
States That Require Notarization
Roughly a dozen states require the seller’s signature on the title to be notarized for the transfer to be valid, and a few of those also require the buyer’s signature to be notarized. Notarization means signing in front of a certified notary public, who checks your ID and applies an official stamp. The notary confirms your identity. The notary does not verify anything about the sale itself.
If your state requires it, the title will have a notary block with space for the notary’s signature, seal, and commission expiration date. Do not sign the title before you get to the notary. A notary who did not watch you sign cannot legally notarize that signature, and the only fix is to apply for a duplicate title and start over. Check your state motor vehicle agency’s website before signing to confirm whether notarization applies.
Signing for Someone Else
If the owner cannot be at the sale, they can authorize someone else to sign through a power of attorney. Most state motor vehicle agencies accept either a general POA or a vehicle-specific POA form the agency publishes. The document generally has to include the vehicle identification number, the name of the authorized agent, and the owner’s signature granting the authority.
When you sign as an agent, the format is the owner’s name, then “by,” then your name, then “as POA.” For example: “Jane Doe by John Smith as POA.” The original POA, or a copy, has to accompany the title when it is submitted to the motor vehicle office.
A deceased owner is different. A family member cannot simply sign the title. If the vehicle was jointly titled with “or” between the names, the surviving co-owner can usually sign and transfer by presenting a death certificate. If the deceased was the sole owner, an executor or administrator appointed by a probate court typically has to handle the transfer, bringing the court appointment documents, a death certificate, and the original title to the motor vehicle office. Some states offer simplified procedures for small estates or for vehicles with a designated beneficiary on file.
If Your Title Is Electronic
A growing number of states issue electronic titles rather than paper, especially while a lien is active. There is nothing to physically sign on an electronic title. To sell, you generally have to request a paper title from your state’s motor vehicle agency, or in some states from the lienholder once the loan is paid off. Once the lien is released, some states automatically mail a paper title; others require a request. Build in a few weeks before the sale, because you cannot sign anything until the paper copy arrives.
Mistakes That Void the Title
Signing errors are unforgiving. Motor vehicle offices enforce strict rules on the condition of the document, and small mistakes can force everyone back to square one. The most common problems:
- Wrong ink color. Use black or blue ballpoint only. Pencil, marker, gel pen, or any other color gets the title rejected.
- White-out or erasures. Any correction fluid, scratch-out, or overwritten text invalidates the whole title. Do not try to fix a mistake on the document.
- Signing on the wrong line. Seller in the seller’s block, buyer in the buyer’s block. Signatures in the wrong spot cannot be corrected on the original.
- Name mismatch. Your signature has to match the name printed on the title. If your legal name has changed, update the title before selling.
- Blank fields. Every labeled field in the assignment section needs an entry. A missing sale date, price, or address is enough to reject the application.
How to Fix a Signing Error
If someone signs the wrong line, uses the wrong ink, or makes an uncorrectable mistake, the usual remedy is to apply for a duplicate title through the state motor vehicle agency. The duplicate arrives with a clean assignment section so everyone can sign correctly. Some states accept a notarized affidavit of correction for minor issues like a misspelled name, which avoids the wait for a replacement. Call your local motor vehicle office before assuming you need a full duplicate; the right fix depends on the specific error.
After the Signatures
Once the title is signed, the buyer should register the vehicle promptly. Most states give buyers between 15 and 30 days from the sale date to submit the title and complete the transfer. Missing the window means late fees, and in some states you cannot legally drive the vehicle on public roads until registration is current. The deadline varies by state, so check yours before closing. If you are the seller, keep a copy of the signed title and the bill of sale; until the buyer registers, traffic and parking tickets tied to the plates can still come back to you.
