Joint and co-owned vehicle titles are legally binding ownership arrangements, and the single word connecting the names on the document — “And,” “Or,” or “And/Or” — decides whether either owner can act alone or whether every signature is required. That one choice controls sales, transfers, refinancing, and most of the headaches that follow. Co-ownership also carries liability, tax, and inheritance consequences that are easier to plan for than to unwind. Rules vary by state, so confirm the specifics with your local motor vehicle agency before you file anything.
What the Conjunction Between the Names Actually Does
The word between co-owners’ names is not formatting. It is a legal designation.
- “And” means every listed owner must sign off on any sale, transfer, or re-titling. Nobody acts alone. This is the most restrictive option and the one that creates the most problems when co-owners stop getting along.
- “Or” means any one owner can sell the vehicle, transfer the title, or make changes without the other owner’s signature. Maximum individual freedom, and also the risk that your co-owner sells the car without telling you.
- “And/Or” defaults in most states to the “Or” standard, letting either owner act independently.
Most states default to requiring all signatures unless the title explicitly uses “Or” or “And/Or.” If the conjunction is missing or ambiguous, expect the motor vehicle agency to treat it as “And” and demand every co-owner’s signature before processing anything. Decide before you file how much unilateral control you are comfortable giving the other person. Changing it later means re-titling the vehicle from scratch and paying the fee again.
Liability You Take On by Being a Co-Owner
Putting your name on a title alongside someone else does not just give you ownership rights. It can make you financially responsible for what they do behind the wheel.
Several states have owner-liability statutes that hold every person on the title responsible when the vehicle causes injury or property damage, regardless of who was driving. The common-law doctrine of negligent entrustment can apply anywhere: if you share ownership with someone you know has a history of reckless driving or DUI convictions, a court may hold you liable for injuries they cause. The reasoning is that you had the power to keep an incompetent driver away from the vehicle and did not.
A co-owner’s personal debts can also reach the car. If one co-owner has a judgment against them, a creditor may attempt to attach that person’s interest in the vehicle. Married couples in some states can hold property as tenants by the entirety, which generally shields the vehicle from one spouse’s individual creditors, but if the debt becomes a joint obligation that protection collapses. For unmarried co-owners under a basic “And” or “Or” title, the debtor’s share is often fair game.
Bankruptcy adds another layer. When one co-owner files, the bankruptcy trustee evaluates that person’s interest in the vehicle. If the interest has equity beyond what state exemption laws protect, the trustee can force a sale even though you co-own the car and did nothing wrong. Your options are to buy out the debtor’s share or take your portion of the proceeds, and you may lose access to the vehicle while the case moves.
Tax Consequences of Adding Someone to a Title
Adding someone to a vehicle title without receiving payment in return is treated as a gift under federal tax law. If the value of the ownership interest you give away exceeds $19,000 in 2026, you must file a gift tax return (IRS Form 709). Married couples who elect to split gifts can transfer up to $38,000 per recipient before triggering a filing requirement.1Internal Revenue Service. Frequently Asked Questions on Gift Taxes Filing the return does not necessarily mean you owe tax. The lifetime gift and estate tax exclusion for 2026 is $15,000,000, so most people will never actually pay gift tax.2Internal Revenue Service. What’s New – Estate and Gift Tax But skipping the form when it is required is a compliance problem you do not want.
On the state side, many jurisdictions exempt title transfers between immediate family members from sales tax, but the definition of immediate family and the scope of the exemption vary. Some states only exempt transfers between spouses or parents and children. Others extend it to siblings, grandparents, or in-laws. A few charge sales tax on every transfer regardless of relationship. Check with your state’s motor vehicle agency or revenue department before assuming a family transfer is tax-free.
What Happens When a Co-Owner Dies
What happens to a jointly titled vehicle at death depends entirely on how the title was structured while both owners were alive.
If the title includes a “Joint Tenancy with Right of Survivorship” designation, the surviving owner automatically gets full ownership without going through probate. The survivor typically brings a certified death certificate and a written statement confirming the death to the motor vehicle agency. Some states provide a fill-in-the-blank form. Once processed, the agency reissues the title in the survivor’s name alone.
Roughly half the states also offer a Transfer on Death (TOD) designation for vehicle titles. A TOD lets you name a beneficiary who has no ownership rights while you are alive but inherits the vehicle automatically at your death, again without probate. The beneficiary presents the death certificate and proof of identity to claim the title. This is useful when you want to pass a vehicle to someone without making them a co-owner during your lifetime.
When neither survivorship language nor a TOD designation appears on the title, the deceased co-owner’s share becomes part of their estate. The executor or administrator must authorize any sale or transfer. This can take months, and the surviving co-owner may not be able to sell or even re-register the vehicle in the meantime. Setting up the title correctly from the start avoids this entirely.
Removing a Co-Owner Later
Removing a name from a joint title requires re-titling the vehicle, and the process hinges on the conjunction that was used when the title was first issued. If the title uses “And,” both owners must sign the back of the title to release their interest. If it uses “Or,” either owner can initiate the change alone.
The departing co-owner completes the assignment-of-title section on the back of the existing title, formally relinquishing their claim. The remaining owner submits a new title application and pays the standard titling fee. Until the state issues the new title, the old joint title remains the operative document, so do not throw it away or let the departing co-owner walk off with it before the assignment section is filled out.
Failing to update the title after a co-owner exits creates real exposure. If the vehicle is involved in an accident while the departed person is still on the title, they can be dragged into a lawsuit. The person still listed also remains technically responsible for the vehicle in some jurisdictions. Clean up the paperwork promptly.
When a Co-Owner Refuses to Sign
If the title uses “And” and your co-owner will not sign, you are stuck voluntarily. You cannot sell, trade in, or re-title the vehicle without their signature. This situation comes up constantly in divorces, breakups, and family falling-outs.
Your main remedy is a court order. You can file a civil action asking a judge to order the transfer or partition of the vehicle. In a divorce, the court handles this as part of property division. Outside divorce, you file a petition in civil court, and if the judge agrees, the court order substitutes for the missing signature. Bring the certified court order, with the judge’s signature and the court seal, along with the existing title and a new application, to the motor vehicle agency. Expect attorney fees and court costs on top of the re-titling fee.
Trying to force the other person’s hand by letting the registration lapse or dropping insurance backfires more often than it works. Driving an unregistered or uninsured vehicle creates legal problems for both owners and changes nothing on the title. The court-order path is slower, but it is the one that resolves the ownership question.
Paperwork and Costs at the Counter
Both co-owners must provide valid government-issued identification, such as a driver’s license or passport, when applying for a joint title. The existing title, or a Manufacturer’s Certificate of Origin for a new vehicle, is surrendered as part of the application. If a lender is financing the purchase, the lienholder’s name and mailing address go on the paperwork, and the physical title is usually mailed to the lender rather than to either owner.
Names on the application must match the identification exactly, and the conjunction between the names goes in the designated ownership section of the form. Print clearly and double-check the conjunction before submitting. Most states also require proof of insurance meeting minimum liability standards before issuing a new title or registration; call your insurer first to find out whether every co-owner must appear on the same policy.
Title fees run roughly $15 to $100 depending on the state. Sales or excise tax is collected at the same time, based on purchase price or fair market value, with state rates ranging from 0% to over 8% and local surcharges on top in many places. Annual registration is a separate ongoing cost. If you need to re-title later to change a conjunction or remove a co-owner, you pay the full titling fee again, which is one more reason to get the structure right the first time.
