Yes, in most cases, both owners must sign the vehicle title for a sale to be legally valid. This requirement is almost universal when the names on the title are connected by the word "and" (e.g., John Doe AND Jane Doe). The title is a document proving ownership, and all listed owners must consent to the transfer. If even one signature is missing, the new buyer cannot register the vehicle, and the sale is invalid.
The key factor is how your names are listed on the title. There are two common designations:
A critical first step is to check if there is a lienholder (a bank or lender) listed on the title. If the car was financed and the loan is not fully paid off, the lienholder holds a financial interest in the vehicle. You must contact them to pay off the loan and obtain the title or a lien release before any owners can sign it over to a new buyer.
Here is a breakdown of common scenarios:
| Ownership Scenario | Signature(s) Required | Key Supporting Evidence / Data Point |
|---|---|---|
| Two owners, names joined by "and" | Both owners must sign. | Standard practice in all 50 states; the title document itself will specify this requirement. |
| Two owners, names joined by "or" | Either owner can sign alone. | Less common but legally binding; allows for individual decision-making. |
| Presence of a lienholder (loan not paid) | Lienholder must release interest and then all owners must sign. | The title will explicitly state the lienholder's name and address; the loan payoff amount is required. |
| One owner is deceased | Surviving owner provides death certificate and may need to obtain a new title before selling. | Process varies by state probate law; often requires submitting forms to the DMV. |
| One owner is unavailable (e.g., out of state) | A power of attorney can be granted to the other owner to sign on their behalf. | The Power of Attorney document must be specific to vehicle titles and comply with state law. |
Before attempting to sell, always physically inspect your title to confirm the exact wording of the ownership section. If a required signer is unavailable, you will need to arrange a durable power of attorney specifically for the vehicle transaction. Attempting to forge a signature is illegal and will result in the sale being voided.

















Check the title right now. Look at how your names are written. If it says "and," you both have to sign. It's that simple. If one of you is out of town or just can't be there, you'll need to get a power of attorney document set up so the other can sign legally. Don't risk it—a missing signature makes the whole sale fall apart when the buyer tries to register the car.

Think of the title as a check. If a check is made out to two people with "and," both must endorse it to cash it. A car title works the same way. The "and" is a lock requiring two keys. If your partner is unavailable, a power of attorney acts as a certified copy of their key. Forging a signature might seem like a quick fix, but it's fraud and will cause major legal headaches for everyone involved later.

From a practical standpoint, this is the first thing a serious buyer or dealership will check. They want a clean, properly signed title so they can register the car without any DMV hassles. If the signatures don't match the ownership on the title, they'll away. It's a huge red flag. Getting it right from the start protects you from the deal falling through at the last minute and ensures a smooth, legal transfer of ownership.

Beyond the immediate sale, a correctly signed title protects you from future liability. Once the title is signed over and the car is sold, the new owner is responsible for it. If the transfer was done improperly because a signature was missing, you could potentially be held responsible if the car is involved in an accident or gets parking tickets before the new owner registers it. Ensuring both owners sign is the final step in cleanly severing your ties to the vehicle.
