Whether a co-borrower can take the car comes down to one document: the title. If both names are on the title, you generally have equal legal right to possess the vehicle, and taking it is a civil matter between co-owners rather than a crime. If your name is only on the loan but not on the title, you have no ownership rights, and taking the car without the titled owner’s permission can be charged as theft. The loan agreement tells you who owes money. The title tells you who owns the car. Those are two different questions, and confusing them is where most co-borrowers get into trouble.
Co-Borrower or Co-Signer? Check Before You Do Anything
People use “co-borrower” and “co-signer” as if they mean the same thing. Legally, they don’t. A co-borrower shares both the payment obligation and ownership of the vehicle, and both names typically appear on the title. A co-signer guarantees the loan payments but has no ownership stake; the co-signer’s name appears on the loan paperwork only.
If you co-signed and the primary borrower has the car, you cannot take it. Your obligation is purely financial. The car belongs to whoever is on the title, and a co-signer who drives off with it can be charged with theft, because from a legal standpoint it isn’t their property. The payments you may have been making do not change that.
If you are a true co-borrower with your name on both the loan and the title, you share ownership. In most circumstances neither party can unilaterally exclude the other from using the vehicle. Everything that follows assumes you have already pulled the title and confirmed which category you fall into.
How the Title Actually Controls Possession
The names on the title are the names with legal rights to the vehicle. It does not matter who picked out the car, who makes the monthly payments, or what anyone agreed to verbally. If only one co-borrower’s name appears on the title, that person is the legal owner and the other co-borrower owes money on a car they don’t own.
“And” Versus “Or” on the Title
When two names appear on a title, the small word between them changes each person’s authority. A title reading “John Doe AND Jane Smith” requires both signatures to sell, transfer, or otherwise dispose of the vehicle. Neither owner can act alone. A title reading “John Doe OR Jane Smith” lets either person sell or transfer the vehicle independently, without the other’s signature.
For a possession dispute, the “and” configuration protects both parties because neither can sell the car out from under the other. The “or” configuration creates real risk: one co-owner can legally sell the vehicle without telling the other, leaving them to sort out the financial fallout afterward.
The Lien Blocks Title Changes
While the loan is unpaid, the lender holds a lien recorded on the title. That lien prevents either co-borrower from transferring ownership, adding names, or removing names without the lender’s approval. Even when both co-borrowers agree to change the title, the lienholder has to sign off. The lien is released only when the loan is paid in full.
When Taking the Car Crosses Into Theft or Conversion
This is where the stakes get real. Whether taking the car is legal depends entirely on your title status.
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 the loan or that you have been making the payments. Police and prosecutors look at the title, not the loan agreement, to determine who owns the car.
Even between co-owners who are both on the title, how you take the car matters. The tort of conversion applies when someone exercises control over another person’s property in a way that is inconsistent with that person’s rights. A co-owner who hides the car, changes the locks, or refuses the other any access can face a conversion claim, with damages measured by the excluded co-owner’s share of the vehicle’s fair market value.
When both names are on the title, police will almost always decline to get involved if one co-borrower takes the car. They treat it as a civil dispute between co-owners. The excluded co-borrower’s remedy is in court, not at the police station.
Don’t Try to Force the Issue by Skipping Payments
Some co-borrowers try to pressure the other party by withholding payments. This tends to backfire badly.
Once the loan is in default, the lender enters the picture with more power than either co-borrower. Under the Uniform Commercial Code, the lender keeps a security interest in the vehicle until the loan is satisfied and can repossess the car if the loan goes into default, regardless of which co-borrower has possession at the time.1Legal Information Institute. UCC 9-609 – Secured Party’s Right to Take Possession After Default Both co-borrowers are jointly and individually liable for the full balance, and the lender can pursue either party for the entire amount.
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 are in default. After repossession the lender typically sells the vehicle, and if the sale price does not cover the balance, both co-borrowers can be sued for the deficiency.2Federal Trade Commission. Vehicle Repossession
Missed payments hit both credit reports. The Consumer Financial Protection Bureau warns that any missed payments on a co-signed or co-borrowed loan appear on both borrowers’ credit reports and can damage both scores.3Consumer Financial Protection Bureau. Should I Agree to Co-sign Someone Else’s Car Loan? A repossession can stay on credit reports for up to seven years. The co-borrower who does not have the car still has every incentive to keep the loan current, which is why some people end up making payments on a vehicle they cannot even drive.
Court Options to Recover the Car
When co-borrowers cannot agree, several legal routes exist to force a resolution.
Replevin
A replevin action is a lawsuit designed specifically to recover personal property that someone else is wrongfully holding. If your name is on the title and the other co-borrower will not give you access to the car, you can file a replevin complaint in your local court. 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. These cases tend to move faster than other civil litigation, though timelines vary by state.
Declaratory Judgment
If the underlying question is who actually has rights to the vehicle rather than just recovering it, either co-borrower can ask a court for a declaratory judgment. The judge examines the loan agreement, the title, payment records, and any other evidence, then formally declares who has legal rights to the car. 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 does not automatically enforce them if the losing party refuses to comply.
Small Claims Court
If the vehicle’s value falls within your state’s small claims limit, this is often the most accessible option. Filing fees are usually a few hundred dollars and you do not need a lawyer. Small claims courts can order one party to return the vehicle or compensate the other for their share of its value. Dollar limits vary significantly by state, so check whether your car’s value qualifies before filing.
Mediation
Mediation puts a neutral third party in the middle to help both sides negotiate. It is cheaper and faster than litigation and works best when both co-borrowers are willing to compromise. A mediated agreement can be made legally binding once both parties sign.
Ways to Resolve It Without a Judge
Litigation is slow and expensive. Most co-borrower disputes are better resolved directly.
The cleanest solution is usually for one co-borrower to refinance the loan alone. Refinancing pays off the original joint loan and replaces it with a new one that only that person is responsible for. The catch: the remaining borrower has to qualify independently on their own credit, income, and existing debt. If they cannot qualify, this option is off the table.
If neither co-borrower can take over the loan solo, selling the car and splitting the proceeds is often the most practical outcome. Both signatures are needed if the title uses “and.” If the car is worth less than the remaining balance, both parties need to cover the shortfall to clear the lien before the sale closes.
A voluntary buyout lets one co-borrower pay the other a negotiated amount and then refinance or pay off the loan. This works when both sides agree on the car’s current value and on fair compensation for any equity built. Put the agreement in writing, even if you are still on good terms.
If Divorce Is Involved
Co-borrower disputes often surface during divorce. A family court can order one spouse to take over the car and its loan, or order the vehicle sold. Here is the trap: a divorce decree assigning the car to one spouse does not release the other spouse from the loan. The lender was not a party to the divorce and is not bound by its terms. If the spouse who got the car stops paying, the lender can still come after the other one for the full balance. Refinancing into a single name is usually the only way to actually get off the loan. For unmarried co-borrowers who split up, no family court process applies, and disputes play out in regular civil court using the remedies above.
Protecting Yourself Going Forward
If you are entering a co-borrowing arrangement, make sure both names go on the title, not just the loan. Choose the “and” conjunction on the title so neither party can sell the car without the other’s consent. Put your understanding about who will use the car and who will pay in writing, even if it is just a confirming email. That paper trail becomes your strongest evidence if the relationship later sours.
If you are already in a dispute, start by pulling the title to confirm exactly whose names appear and how they are connected. That one document tells you more about your legal position than anything else. Keep records of every payment you have made, and put communications with the other co-borrower in writing rather than over the phone. And do not stop making loan payments to pressure the other person into giving up the car. Both credit scores will suffer, and the lender can repossess the vehicle out from under both of you.
