How to Add Someone to a Car Title
Adding a spouse, family member, or business partner to your vehicle title requires a new title from your state DMV. The key decision is AND vs OR — it has permanent legal consequences.
AND vs OR — Which Should You Choose?
Both owners must agree to sell or transfer — maximum protection against unauthorized sale
Both owners must sign every transaction — inconvenient for spouses who manage separately
Either owner can sell or transfer independently — maximum flexibility
Either owner can sell the vehicle without the other's consent — significant legal risk
Either owner can transact alone OR both together — California specific option

What to Check Before Adding a Co-Owner
If the vehicle has an outstanding loan, your lienholder must approve adding a co-owner. Some lenders require refinancing. Contact your lender 30+ days before the intended transaction.
Adding a non-exempt co-owner triggers a partial ownership transfer, which may be taxable. Family members (spouse, parent-child) often qualify for gift exemptions. Verify your state's rules before proceeding.
Adding a co-owner may affect your insurance policy. Verify with your insurer that the new co-owner is covered. If they will drive the vehicle, they must be listed as a driver.
This decision is permanent until the title is re-issued. AND requires both signatures for future sales. OR allows either owner to act alone. There is no "fix later" option without getting a new title.
