To add someone to your car title, you file a title transfer with your state’s motor vehicle agency: bring the original title, valid ID for both people, an odometer reading, a completed title application, and payment for the title fee. Even though the car isn’t being sold and you’re keeping it, the state treats adding a co-owner as an ownership change, so the paperwork, signatures, and fees mirror a standard sale. Most people finish in one DMV visit, but a loan on the vehicle, insurance, and a few tax questions can trip up the process if you don’t handle them first.
Choose “And” or “Or” Before You Sign Anything
The small word printed between the two names on the new title controls who can sell, trade, or transfer the car later. The DMV clerk will ask you to pick, and changing your mind afterward means another full title transfer with another set of fees.
- “Or” between the names lets either owner sign the car over on their own. Convenient, but the other person has no veto if you decide to sell.
- “And” between the names requires both signatures for any future transaction. It protects both of you and creates a real problem if one co-owner later becomes unreachable or uncooperative.
- “And/or” works like “or” in most states: one signature is enough.
If the application is left blank, most states default to “and.” That default quietly locks both owners into needing each other’s consent for anything the title touches, so pick deliberately rather than letting the form choose for you.
Documents to Bring
Gather everything before you go. One missing item usually means a second trip.
- The original title. Not a photocopy. If it’s lost, apply for a duplicate first, which is a separate fee and a separate wait.
- Valid photo ID for both people. Some states require both parties to appear in person at the counter.
- The odometer reading. Federal law requires the transferor to disclose the vehicle’s cumulative mileage on the title or on a separate odometer disclosure statement during any ownership transfer, with exemptions for older vehicles.1eCFR. 49 CFR Part 580 – Odometer Disclosure Requirements
- A lien release if you recently paid off the car. This is the letter from your lender confirming they no longer have a claim on the vehicle.
- A gift affidavit or a bill of sale. If no money is changing hands, most states use a gift affidavit to waive or reduce sales tax. If the co-owner is paying you, a bill of sale documents the amount.
- The state’s title application form, sometimes called an “Application for Certificate of Title.” Download it from your state DMV site or pick one up at the office.
If There’s Still a Loan on the Car
This is where the process most often stalls. When a lender holds a lien, that lender’s name sits on the title, and you generally cannot add a co-owner without their permission. Some lenders will approve the change with a written request. Others refuse any title changes until the loan is paid off. A few require the new co-owner to qualify on the loan through a refinance.
Call the lender before you head to the DMV. If the lienholder won’t authorize the change, the DMV will not process it, because the lien takes priority over your paperwork. If you can pay the remaining balance, do that first, get the lien release in hand, and then treat the co-owner addition as a clean title transfer.
What Happens at the DMV
The paperwork looks like a sale even though you’re keeping the car. On the back of the existing title, the current owner signs in the seller or transferor section. Both the current owner and the new co-owner sign in the buyer or transferee section. Record the odometer reading in the space provided.
On the title application, enter both names and mark the conjunction you chose. Check the VIN, year, make, and model against the existing title; errors here send the file back and delay the new title. Some states require notarized signatures on the title or the application. Many DMVs have a notary on site, but confirm before you go so you’re not scrambling for one.
Hand everything to the clerk with payment. In most states you leave with a temporary registration document, and the new title carrying both names arrives by mail within a few weeks.
Fees, Sales Tax, and Other Costs
Title transfer fees typically fall between $15 and $100 depending on the state. Beyond the base fee, plan for some or all of the following:
- Sales tax if the state treats the addition as a sale, calculated on the sale price or the vehicle’s fair market value. Many states waive or reduce sales tax for vehicles gifted between immediate family members, but you have to submit a gift affidavit to claim the exemption.
- Registration fees if the registration record needs updating to reflect the new owner.
- Notary fees where signatures must be notarized, generally $5 to $25 per signature.
- Late penalties in states that set a deadline for reporting ownership changes. Miss the window and the fees can compound monthly.
Check your state’s DMV site for exact amounts and accepted payment methods before you go. Some offices still take only checks or money orders.
Gift Tax When No Money Changes Hands
Adding someone to your title without payment is a gift for federal tax purposes. Giving a co-owner a 50% interest in a $30,000 car is a $15,000 gift. That sits under the federal annual gift tax exclusion, which for 2026 is $19,000 per recipient.2Internal Revenue Service.

If the interest you’re transferring is worth more than $19,000, you’ll need to file IRS Form 709.3Internal Revenue Service. Instructions for Form 709 (2025) Filing doesn’t automatically mean you owe tax; it counts against your lifetime exemption. For most family car additions the annual exclusion covers the full amount and no return is required, but the math is worth running on a high-value vehicle.
Update Your Insurance and Understand the Liability
Adding a co-owner without updating the auto policy creates a gap that can surface at a claim. Insurers generally expect every titled owner to be listed on the policy. Call your insurer before or immediately after the title change. Your premium may go up or down depending on the new person’s age and driving record.
The liability side matters more than most people realize. As a titled co-owner you can be held financially responsible if the other owner causes an accident. The exact rule depends on the state: some impose vicarious liability on vehicle owners regardless of who was driving, some require proof of negligent entrustment, and some apply a family purpose doctrine to family members driving for family reasons. Adding someone to the title extends your legal exposure to their driving, and that’s worth weighing before you sign.
Removing a Co-Owner Later
Taking a name off runs the same process in reverse, and the conjunction you picked at the start decides how hard that will be. With an “or” title, the remaining owner can sign as both transferor and transferee and complete the change without the departing co-owner. With an “and” title, both signatures are required, which becomes a real obstacle in a dispute or a divorce. Either way, removal is a fresh title transfer with another round of fees and, usually, a new title application.
