On a car title, the word between two owners’ names decides who has to sign. “And” versus “or” on a car title is the difference between needing both signatures for every transaction and letting either owner act alone. It also decides what happens when one owner dies, how creditors can reach the vehicle, and whether adding a co-owner triggers a federal gift tax filing.
How “And” Works
When two names are joined by “and,” neither owner can act without the other. Selling the vehicle, signing the title over, or re-registering it in a new state requires both signatures. If one co-owner wants to sell and the other refuses, the car stays put. That protects both parties from unauthorized transfers, but it turns a routine sale into a coordination problem.
The bigger consequence shows up at death. An “and” title does not carry an automatic right of survivorship in most states. The deceased owner’s share becomes part of their estate, so the surviving owner may need to go through probate or submit an heirship affidavit before the title can be reissued. That process can take weeks or months, and during that window selling or re-titling the vehicle is effectively frozen.
How “Or” Works
“Or” between names gives each owner independent authority. Either person can sign the title over to a buyer, register the vehicle, or handle any other transaction without the other owner’s involvement. It’s the more flexible arrangement, and it’s the one lenders and family members often choose when they want to avoid logistical headaches later.
Survivorship is the real distinction. When one co-owner on an “or” title dies, their interest passes automatically to the surviving owner. No probate, no estate proceeding, no waiting for a court. The surviving owner presents a death certificate to the motor vehicle agency and receives a new title in their name alone, usually in a single visit.
What “And/Or” Means
Some states allow “and/or” between co-owners’ names. Most motor vehicle agencies treat “and/or” the same as “or,” meaning either owner can act independently. Interpretation is not perfectly uniform, though, and a handful of jurisdictions may still require both signatures for certain transactions while both owners are alive. If your title reads “and/or,” a call to your state’s motor vehicle agency will confirm how they handle it.
What Happens When a Co-Owner Dies
This is where the choice of conjunction matters most, and where many people first discover the consequences of a word they never thought about.
“Or” Titles
The surviving owner contacts the motor vehicle agency with a certified copy of the death certificate. The agency reissues the title in the survivor’s name alone. No probate court, no estate attorney. Some states also require a short transfer form, but the process is designed to be handled without legal counsel.
“And” Titles
The deceased owner’s interest goes into their estate. If they left a will and the estate goes through probate, the executor can eventually sign the title over once the court issues authorization. If there is no will or no probate is opened, many states allow an affidavit of heirship as a shortcut: the surviving heirs swear under oath that they are the rightful recipients, and the motor vehicle agency processes the transfer based on that affidavit. Either path is slower and more paperwork-intensive than the “or” process.
Creditor and Liability Risks
Co-ownership creates exposure that many people don’t consider until a lawsuit or debt collection is already underway.
Creditor Access
With an “and” title, a judgment creditor pursuing one owner’s personal debt can generally only claim that owner’s interest in the vehicle, not the whole thing. Forcing a sale of the entire car over the other owner’s objection is difficult in most states. An “or” title offers less protection. Because either owner has full authority over the vehicle, some jurisdictions allow a creditor to levy against the entire vehicle to satisfy just one co-owner’s debt.
Accident Liability
If your name is on the title, you may face liability when your co-owner causes an accident, even if you weren’t in the vehicle. Most states follow the principle that an owner who gives permission to drive bears responsibility for what happens, and permission is essentially built into co-ownership. Both owners can be named in a lawsuit, and in states that recognize joint and several liability, each owner can be held responsible for the full amount of damages. This risk exists regardless of whether the title says “and” or “or.”
Insurance for Co-Owned Vehicles
Most states allow the insurance policyholder and the registered owner to be different people. But if two names appear on the title, both owners should be listed on the insurance policy as either the policyholder or a covered driver. When only one co-owner is on the policy and the other causes an accident, the insurance company may delay or withhold payment while it investigates the mismatch. Getting both names on the policy from the start avoids that problem.
Gift Tax When Adding a Co-Owner
Adding someone to your car title without receiving payment is a gift in the eyes of the IRS. Gift tax applies to any transfer of property where you receive nothing, or less than full value, in return. Intent doesn’t matter.
The calculation is based on the vehicle’s fair market value at the time of the transfer. Add a co-owner to a car worth $30,000 and you have given them a $15,000 interest. For 2026, the annual gift tax exclusion is $19,000 per recipient, so that $15,000 gift would not require a filing.1Internal Revenue Service. What’s New — Estate and Gift Tax If the vehicle is worth $50,000, the $25,000 gift exceeds the exclusion, and you’d need to file IRS Form 709. The $6,000 overage counts against your lifetime exemption rather than triggering an immediate tax bill, but the filing obligation still applies.2Internal Revenue Service. Gift Tax
Changing the Conjunction on Your Title
If you already have a title with the wrong conjunction, you can change it, but the process requires a new title application. Both current owners typically need to submit a joint request to the motor vehicle agency, and the agency reissues the title with the updated wording. Expect a title reissuance fee, which generally runs between $28 and $85 depending on the state. If there is a lien on the vehicle, the lienholder will need to authorize the change.
This is worth doing proactively. Switching from “and” to “or” before a co-owner becomes seriously ill can save the surviving owner months of probate. Going the other direction, from “or” to “and,” makes sense when both parties want veto power over any future sale.
When a Lien Complicates Things
Whichever word appears between the owners’ names, a lienholder’s interest takes priority. If the vehicle is financed, the lender holds a lien on the title, and no co-owner can sell or transfer the vehicle without paying off the loan or getting the lender’s written consent. The conjunction between owners’ names governs the relationship between the co-owners; it does not override the lender’s security interest. Any plan to sell, transfer, or change the title wording needs to account for the lien first.
