The seller signs on the back, the buyer signs nowhere until after purchase
The person selling the car signs the back of the title document, usually in a section labeled "Seller's Signature" or "Assignment of Title." The buyer does not sign the title at the time of sale. Instead, the buyer receives the signed title from the seller and then submits it to the state's motor vehicle department (often called the DMV, Secretary of State, or Department of Transportation depending on your state) along with other paperwork to register the vehicle in their name.
The exact location of the seller's signature line varies by state because each state prints its own title form. Some states have the signature line in the lower right corner of the back; others place it in the center or left side. The title document itself will label where the signature goes, so you do not have to guess. If you cannot find the line, check your state's motor vehicle department website for a blank sample of the title form, or call their office to ask.
What matters most is that the seller signs in ink (not pencil), that the signature matches the name printed on the title, and that it happens before the buyer takes possession of the vehicle. A title signed in pencil or by someone other than the registered owner will be rejected by the motor vehicle department when you try to register it.
Key Takeaways
- The seller signs the back of the title in the section marked for the seller's signature, and this must happen before the buyer takes the car.
- The buyer does not sign the title; instead, the buyer submits the signed title to the state motor vehicle department along with a bill of sale and registration forms.
- The signature must be in ink, must match the name on the title exactly, and must be from the person whose name appears as the registered owner.
- Each state's title form looks different, so check your state's motor vehicle department website if you cannot locate the signature line on your specific form.
- If the title is signed in pencil, signed by the wrong person, or left unsigned, the motor vehicle department will reject it and delay your registration.
Why the seller signs and the buyer does not
The title is a legal document that proves ownership. When the seller signs it, they are transferring that ownership to the buyer. The signature is the seller's authorization to release the vehicle. The buyer does not sign the title because the buyer is not transferring ownership to anyone else at that moment—the buyer is receiving it.
After the buyer registers the vehicle with the state, the state issues a new title in the buyer's name. If that buyer later sells the car, they will sign the back of their new title, and the cycle repeats. The motor vehicle department keeps a record of each transfer, so the state always knows who owns the vehicle.
What happens if the signature is missing or wrong
If the title arrives at the motor vehicle department unsigned, the department will reject it and return it to you. You will then have to contact the seller, get them to sign it, and resubmit it. This delay can take weeks or longer if the seller is hard to reach or has moved.
If the signature does not match the name printed on the title—for example, if the title says "Robert Smith" but the person signs "Bob Smith"—the motor vehicle department may reject it or ask for additional proof that the signer is the registered owner. Some states are stricter about this than others. To avoid this problem, the seller should sign using the exact name that appears on the title, even if they normally go by a nickname.
If someone other than the registered owner signs the title, it is not valid. The motor vehicle department will not process it. Only the person whose name appears on the title has the legal right to sign it and transfer ownership.
Titles with multiple owners and co-owners
If the title lists two owners—for example, "John Smith and Jane Smith"—both must sign the title for the sale to be valid. Some states require both signatures on the same line; others have separate signature lines for each owner. Check your state's title form to see how many signature lines are provided.
If the title says "John Smith or Jane Smith" (with the word "or" instead of "and"), only one of them needs to sign. The word "or" means either owner can transfer the vehicle alone. The word "and" means both must agree.
If you are unsure whether the title says "and" or "or," look at it carefully or contact your state's motor vehicle department. This distinction determines whether you need one signature or two, and getting it wrong will cause the motor vehicle department to reject the title.
Signing a title when there is a lien or loan
If the seller still owes money on the car—meaning a bank or lender holds a lien on the title—the lender must release that lien before the title can be transferred. The seller cannot straightforward sign the title and hand it over. The lender has to sign a release document or provide a separate lien release form.
In some cases, the lender will mail the lien release directly to the buyer. In other cases, the seller must request it from the lender and then give it to the buyer along with the signed title. The buyer then submits both documents to the motor vehicle department. Without the lien release, the motor vehicle department will not register the vehicle in the buyer's name because the lender's claim is still on record.
Notarization and when it is required
Some states require the seller's signature on the title to be notarized, meaning a notary public must witness the signature and stamp the document. Other states do not require notarization. Check your state's motor vehicle department website or the title form itself to see whether notarization is mandatory.
If notarization is required and the seller does not have the signature notarized, the motor vehicle department will reject the title. The seller will have to take the title to a notary, have them witness the signature again, and then resubmit it. Notarization typically costs between $5 and $15 per signature, depending on where you go.
If notarization is not required in your state, you do not need to pay for it. Some sellers choose to have the signature notarized anyway as extra protection, but it is not necessary unless your state's law or the title form says it is.
What to do if you bought a car and the seller has not signed the title
If you have taken possession of the car but the seller has not yet signed the title, you are in a difficult position. You cannot legally register the vehicle in your name without the signed title. Contact the seller when ready and ask them to sign and return the title. If they refuse or are unreachable, you may have a dispute on your hands.
Some states allow you to register a vehicle temporarily without a signed title if you have a bill of sale and proof of purchase, but this is not standard and varies by state. Contact your state's motor vehicle department to ask what options are available to you. If the seller is unwilling to sign, you may need to consult a lawyer about your rights as a buyer.
Frequently Asked Questions
Can I sign the title on behalf of the seller if I have power of attorney?
Power of attorney does not automatically give you the right to sign a title. Some states allow it in specific circumstances, such as if the owner is incapacitated, but you will need to provide legal documentation to the motor vehicle department. Contact your state's motor vehicle department before attempting this, as requirements vary widely.
What if the seller's name on the title does not match their driver's license?
The motor vehicle department will likely ask for proof that the person signing is the registered owner. Bring a marriage certificate, court order, or other legal document showing the name change. The seller may also need to update their name on the title before signing it, which requires a separate transaction with the motor vehicle department.
Do I need to sign the title if I am buying the car but not registering it yet?
No. The buyer never signs the title. Only the seller signs. You will sign registration forms and other paperwork when you submit the title to the motor vehicle department, but not the title itself.
Can the seller sign the title in pencil instead of pen?
No. The motor vehicle department will reject a title signed in pencil because pencil can be erased and altered. The signature must be in ink. If the seller has already signed in pencil, they will need to sign again in ink on a new title form or in a blank area of the same form.
What if I bought a used car from a dealer and they have not given me the signed title?
Dealers are required by law to provide you with a signed title within a set timeframe, which varies by state but is usually 10 to 30 days. If the dealer has not provided it, contact your state's motor vehicle department or consumer protection office to file a complaint. Keep records of your purchase agreement and all communication with the dealer.
