Whether a co-borrower can take the car comes down to one document: the title. If both names appear on the title, each co-owner generally has an equal legal right to possess and use the vehicle. If your name is only on the loan and not on the title, taking the car without the titled owner’s permission can be treated as theft, no matter how many payments you’ve made.
That distinction between being on the loan and being on the title is the single most important factor in these disputes, and it’s the one most people overlook.
Loan Paperwork and Title Are Two Different Things
The loan agreement says who owes the money. The title says who owns the car. Those are separate documents, and they don’t always list the same people.
A true co-borrower shares both the payment obligation and ownership of the vehicle, so both names usually appear on the title as well as the loan. A co-signer is different. A co-signer guarantees the loan but has no ownership stake, so their name shows up on the loan paperwork and nowhere on the title. In everyday speech people use the two terms interchangeably, but the legal positions are not the same.
If you co-signed and the primary borrower has the car, you have no legal right to take it. Your exposure is purely financial: if the payments stop, the lender can come after you for the balance. The vehicle itself belongs to whoever is on the title, and a co-signer who takes it can face criminal charges because, in the eyes of the law, it isn’t their property.
Before doing anything else, pull the title and confirm exactly whose names appear on it. That one document will tell you more about your legal position than the loan contract, the payment history, or any verbal agreement you had with the other person.
How “And” vs. “Or” Changes What One Co-Owner Can Do
When two names appear on a title, the conjunction between them matters.
If the title reads “John Doe AND Jane Smith,” both signatures are required to sell, transfer, or otherwise dispose of the vehicle. Neither owner can act alone. If the title reads “John Doe OR Jane Smith,” either person can sell or transfer the car independently without the other’s signature.
For possession, the “and” configuration protects both parties because neither can dispose of the car unilaterally. The “or” configuration creates real risk: one co-owner can legally sell the vehicle without telling the other, leaving the excluded party to sort out the financial fallout after the fact.
One more wrinkle applies while the loan is unpaid. The lender’s lien sits on the title and blocks either co-borrower from transferring ownership, adding names, or removing names without the lender’s approval. Even if both co-borrowers agree to change the arrangement, the lienholder has to sign off. The lien releases only once the loan is paid in full.
When Taking the Car Crosses a Legal Line
This is where people get into serious trouble. Whether taking the car is legal depends on your title status, and getting it wrong can carry criminal consequences.
If your name is not on the title, taking the vehicle without the titled owner’s permission can constitute theft. It does not matter that you co-signed, that you’ve been making the payments, or that you consider the car partly yours. Police and prosecutors look at the title, not the loan agreement, to decide who owns the vehicle.
Even between two co-owners who are both on the title, certain conduct can create civil liability. The tort of conversion applies when someone exercises control over another person’s property in a way inconsistent with that person’s rights. If one co-owner hides the car, changes the locks, or refuses the other any access, the excluded co-owner may have a conversion claim and can sue for damages equal to their share of the vehicle’s fair market value.
What Police Will and Won’t Do
If both names are on the title and one co-borrower takes the car, police almost always decline to get involved. They treat it as a civil dispute between co-owners rather than a crime, which pushes the excluded co-borrower into court rather than the police station. If only one name is on the title and the other person takes the vehicle, that same call gets treated very differently.
The Financial Fallout Hits Both of You
Regardless of who has the keys, both co-borrowers stay jointly and individually liable for the full loan balance. The lender can pursue either party for the entire amount owed, not just half.
Missed payments on a co-borrowed loan appear on both borrowers’ credit reports and can damage both credit scores.1Consumer Financial Protection Bureau. Should I Agree to Co-sign Someone Else’s Car Loan? A default followed by repossession is worse and can stay on credit reports for up to seven years.
This creates an ugly dynamic. The co-borrower who doesn’t have the car still has every reason to keep the loan current, because their credit is on the line too. Some co-borrowers end up paying for a car they can’t even drive just to protect their score. Whatever you decide to do about possession, don’t stop paying to punish the other person. Both credit reports take the hit, and the lender won’t wait for you two to work it out.
What Default and Repossession Look Like
Default changes the whole picture, because a third party with more leverage than either co-borrower steps in.
In many states, the lender can repossess the vehicle as soon as you default, which typically means missing a payment, and may not have to give advance warning. According to the Federal Trade Commission, the lender “might be able to repossess your car at any time, without notice, and come onto your property to take it” once you’re in default. The consistent limit across states is that the lender cannot “breach the peace” during repossession, which generally rules out physical force, threats, and in some states removing the car from a closed garage.2Federal Trade Commission. Vehicle Repossession
After repossession, the lender usually sells the vehicle. If the sale doesn’t cover what’s owed, the shortfall is called a deficiency, and in most states the lender can sue both co-borrowers for it.2Federal Trade Commission.

Legal Ways to Force the Issue
When co-borrowers can’t agree, several court options exist. None of them are fast or cheap, but they work when nothing else has.
Replevin
A replevin action is a lawsuit built specifically to recover personal property someone else is wrongfully holding. If you’re on the title and the other co-borrower won’t give you access, you can file a replevin complaint locally. You submit an affidavit stating that you have a rightful ownership claim, that the property is being wrongfully detained, and identifying who has it. If the judge is satisfied, the court issues a writ of replevin directing law enforcement to seize the vehicle and return it to you. Timelines vary by state but tend to move faster than typical civil litigation.
Declaratory Judgment
If the underlying question is who has the right to the car rather than simply getting it back, either co-borrower can ask a court for a declaratory judgment. The judge examines the loan agreement, the title, payment records, and other evidence, then formally declares who has legal rights to the vehicle. Courts weigh who is on the title, who has been making payments, the original intent of both parties, and any written communications. The ruling clarifies rights going forward but doesn’t automatically enforce them if the losing party ignores it.
Small Claims Court
If the vehicle’s value falls within your state’s small claims limit, this is often the most accessible route. Filing fees run a few hundred dollars, and you don’t need a lawyer. Small claims can order one party to return the car or compensate the other for their share of its value. Dollar limits vary widely by state, so check whether your vehicle qualifies before filing.
Mediation
Mediation puts a neutral third party in the room to help both sides negotiate. It’s cheaper and faster than a lawsuit and works best when both co-borrowers are willing to bend. A mediator can help structure a buyout, set up a shared-use schedule, or agree on a sale and split of the proceeds. Any agreement reached can be made legally binding once both parties sign.
Cleaner Fixes That Skip Court
Most co-borrower disputes are better resolved outside a courtroom.
Refinance in One Name
The cleanest solution is usually for one co-borrower to refinance the loan solo. Refinancing pays off the joint loan and replaces it with a new one in a single name. The catch is that the remaining borrower has to qualify independently on their own credit, income, and debt load. If they can’t qualify alone, this option is closed.
Sell the Car
If neither co-borrower can take over the loan alone, selling and splitting the proceeds is often the most practical outcome. Both co-borrowers must cooperate in the sale when the title uses “and,” because both signatures are required. If the car is worth less than the remaining loan, both parties need to cover the shortfall so the lien can be cleared before the sale closes.
Buyout
One co-borrower can buy out the other’s interest by paying negotiated compensation and then refinancing or paying off the loan. This works when both parties can agree on the car’s current value and on what each person’s equity share is worth. Put the agreement in writing, even if you’re on good terms.
A Note on Divorce and Separation
Co-borrower car disputes often surface in a divorce or the breakup of a domestic partnership. In a divorce, the family court divides marital property, which usually includes vehicles bought during the marriage regardless of whose name is on the title. A judge can order one spouse to take the car and the loan, or order the vehicle sold. What matters to know: a divorce decree assigning the car to one spouse does not release the other spouse from the loan. The lender wasn’t part of the divorce and isn’t bound by it. If the spouse who got the car stops paying, the lender can still come after the other one. Unmarried co-borrowers have no equivalent family court process and have to use the civil remedies above.
What to Do Right Now
Pull the title and read it carefully. Note whose names appear and whether they’re connected by “and” or “or.” That tells you what you can legally do and what the other co-borrower can do to you.
Gather your payment records. If this ends up in court, a documented history of who paid what becomes one of the strongest pieces of evidence.
Move communication into writing. Text and email create a paper trail that phone calls don’t. If the other co-borrower is refusing access, hiding the car, or threatening to sell it, written messages preserve what was said.
Keep the loan current while you sort things out. Withholding payments as leverage backfires: both credit scores take the damage, and the lender can repossess the car out from under both of you before the dispute is resolved.
