Co-owning a vehicle can be a practical way to reduce costs, share usage, or help a friend manage payments. Whether you’re splitting the purchase of a new car or buying into an existing one, it’s vital to understand how to co-own a car correctly. A written, legally binding agreement ensures everyone’s rights are protected and responsibilities are clear.
Setting Up Legal Co-Ownership
When you buy a vehicle with another person, both names should appear on the car title. The title determines ownership rights and how the vehicle will be handled if one owner passes away.
- Joint Tenancy: Ownership passes automatically to the surviving co-owner. To specify this, list both names as “Alex Brown or Jamie Lee.”
- Tenancy in Common: Each owner controls their share and can transfer it to someone else. For example, “Alex Brown and Jamie Lee” allows each party to pass their share through a will.
If you’re taking a loan, lenders may require both co-owners on the financing agreement. When only one name is on the loan, a written joint ownership agreement should outline how payments are shared, what happens if one person defaults, and how buyouts work.
Before finalizing co-ownership:
- Check for liens on the vehicle using the VIN.
- Verify loan repayment status with the lender.
- Follow your state DMV’s requirements to properly add or change ownership on the title.
Creating a Co-Ownership Agreement
A written agreement prevents misunderstandings and serves as proof of each owner’s rights. Include:
- Both parties’ full legal names and signatures.
- Payment responsibilities and ownership percentages.
- Rules for usage, refueling, and maintenance.
- Procedures for selling, transferring, or buying out ownership shares.
- What happens if one owner fails to make their payments.
Have the agreement notarized to make it enforceable. Notaries can be found in banks or courthouses. Keep signed copies for reference.
Managing and Resolving Disputes
Shared ownership requires strong communication and respect. If conflicts arise:
- Meet face-to-face. Discuss issues calmly and avoid written arguments that can escalate tension.
- Review your agreement. Use it as a guide—not a weapon—to clarify misunderstandings.
- Amend terms when circumstances change, such as different usage schedules or income shifts.
- Seek mediation if disputes persist. Courthouse mediation programs or local bar associations can help.
- Avoid lawsuits whenever possible, as they are time-consuming and costly.
If legal action becomes unavoidable, contact an attorney or local legal aid service for advice. Some lawyers offer unbundled legal services, meaning you only pay for specific help like reviewing contracts or representing you in hearings.
Tips
- Being a co-signer on a car loan doesn’t make you a co-owner. Only names on the title have ownership rights.
- Always verify that the car is lien-free before co-purchasing.
- Consider alternatives like car rentals or car-sharing services if you don’t need frequent access to a vehicle.
By following these steps to co-own a car, you’ll create a fair, transparent, and legally sound partnership that protects both owners and keeps your shared vehicle arrangement running smoothly.
