Title and Ownership Authority
If two names appear on a car title, you might need both owners' signatures, or your state might accept just one. The answer depends on the title's wording, the applicable state rules, and the transfer procedure. An OR title does not always mean either person can sell alone. Before signing or arranging pickup, verify the exact ownership designation and who is authorized to transfer the vehicle.
Read the Names and Ownership Wording on Your Title
Start with the ownership section on the front of the title. Two people may be listed as co-owners, but the words connecting their names can affect the required signatures.
Common arrangements include:
- AND: Both owners commonly must sign to transfer the vehicle.
- OR: Some states accept either owner's signature, while other states require both.
- AND/OR: The meaning depends on the issuing state's rules. It does not automatically mean the same thing as OR.
- Other wording: A slash, survivorship designation, or ownership status printed elsewhere on the title can change the procedure.
For example, an Arizona title listing "Alex Smith AND/OR Jordan Smith" ordinarily requires both living owners to sign when selling. On a California title with the same conjunction, one owner can generally release ownership unless an additional designation changes the requirement.
These are documented differences between state procedures, not exceptions that a seller can choose between.
Also check which names are listed as registered owners and which appear under a lienholder section. A lender's security interest is different from an individual's ownership interest. A person who signed the vehicle loan is not necessarily a titled co-owner.
If you have only the registration, insurance card, or a photograph of an older certificate, obtain the current title information before proceeding.
State-by-State Car Title Signing Requirements
The following comparison is based on official motor vehicle agency guidance checked November 8, 2026.
It addresses ordinary ownership transfers involving two living co-owners. Special transactions involving death, liens, title brands, court orders, and electronic services may require different documents.

Scroll horizontally to see all state requirements and sources.
| Title state | AND | OR | AND/OR | Important exception and official source |
|---|---|---|---|---|
| Arizona | Both owners | Either owner | Both owners | Survivorship affects the procedure after death. Arizona MVD Multiple Owners |
| California | Both owners | One owner | One owner | A slash is treated as AND. JTRS requires all living owners to release ownership. California DMV Basic Transfer Requirements |
| Florida | Both owners | Either owner | Not separately established by the cited Florida statute | The statute addresses AND and OR. Confirm other wording and the applicable transaction procedure. 2026 Florida Statutes, Section 319.22 |
| Minnesota | Both living owners | Both living owners | Both living owners under its general two-owner requirement | OR establishes survivorship rights but does not remove the second living owner's signature requirement. Minnesota DVS Titles and Transfers |
| Wisconsin | All owners | Any listed owner | Not separately addressed in the cited seller guidance | Check any unusual wording with WisDOT before signing. Wisconsin DOT Selling Your Vehicle |
| Maryland | All owners | One owner | Not separately addressed in the cited private-sale guidance | The published guidance describes sales to another person, not a dealer. Buyer and receiving-state requirements may differ. Maryland MVA Selling a Vehicle |
| Nebraska | All named owners | All named owners | All named owners under its general transfer requirement | OR establishes a separate survivorship route after death, not a general one-signature sale rule. Nebraska DMV Transfer of Ownership |
How to interpret the matrix: "Both" or "all" refers to the owners who must endorse the ordinary transfer. It does not necessarily mean they must appear in person together. A properly authorized representative may be accepted in some circumstances.
"Not separately addressed" means the cited issuing-state guidance does not establish a definitive rule for that conjunction. It does not mean either owner is free to sign alone.
Important Scope Limitation
These are selected state examples, not a 50-state legal determination. Confirm the actual document and transaction requirements with the relevant title agency before transferring ownership.
Why OR Does Not Always Mean One Signature
Minnesota provides a particularly important counterexample to common internet advice.
Its official Titles and Transfers manual, revised August 2024, explains that both living joint owners must sign when selling a vehicle. The word OR establishes rights of survivorship, meaning it can affect what happens after an owner's death.
Nebraska's general transfer instructions likewise require all named owners to sign, including when the title uses OR.
By comparison, Arizona, Florida, and Wisconsin expressly permit one listed owner to endorse an ordinary OR-title sale under their respective rules.
A title conjunction can therefore affect more than one legal question. The right to transfer a vehicle while both owners are alive is not necessarily the same as the right to receive ownership after a co-owner dies.
California Has Special Ownership Designations
California's ordinary signing rule is relatively straightforward: AND or slash requires each owner, while OR or AND/OR generally requires one.
However, the California DMV Co-Owners guidance identifies additional ownership statuses.
When a title carries a Joint Tenants with Right of Survivorship designation, abbreviated JTRS, all living co-owners must release their ownership interests for an ordinary transfer.
Tenants in Common and COMPRO designations can also affect the handling of a deceased owner's interest.
The practical lesson is to examine the full ownership section, not only the single word between two names.
Three Hypothetical Selling Situations
Situation 1
Arizona AND/OR
Alex and Jordan are both living owners of an Arizona-titled car. Their names are joined by AND/OR. Alex has the car and wants to sell it because the engine no longer runs.
The condition of the vehicle does not eliminate Jordan's required signature. Arizona's ordinary-sale rule requires both owners to release ownership, so Alex must arrange the necessary participation or approved authorization before proceeding.
Situation 2
California AND/OR
Alex and Jordan instead have a California title showing AND/OR, without a JTRS designation or another special ownership restriction.
California generally accepts one owner's signature to release ownership under its ordinary DMV rule. The seller must still satisfy any applicable lien, disclosure, buyer-processing, or separate legal obligations.
Situation 3
Minnesota OR
Alex and Jordan own a car titled in Minnesota with OR between their names. Both are alive, but Jordan has moved to another state.
Minnesota's published title instructions still require both owners' signatures for the sale. Alex should determine how Jordan can provide the required endorsement before completing the transaction.
These are hypothetical illustrations of official procedures, not Family Car Buyers customer transactions.
Electronic Titles and Out-of-State Transfers Can Change the Process
A paper-title signing rule does not automatically describe the steps required by a particular online transfer service.
Some electronic systems impose their own participation requirements, while others exclude certain vehicle types or transactions altogether.
Electronic Transfer Comparison
Scroll horizontally to compare electronic transfer programs.
| Transfer program | Multiple-owner participation | Eligibility and limitations |
|---|---|---|
| Arizona in-state eTitle Transfer | If there are two sellers, both must electronically release ownership. | Requires an eligible Arizona-titled vehicle, current Arizona registration, qualifying accounts, no liens, and other conditions. Certain brands or legal-document transactions are excluded. |
| Arizona out-of-state eTitle Transfer | Requires a single seller for the online transaction, including an eligible vehicle with two owners joined by OR. | Not every state participates. The vehicle and parties must meet the separate out-of-state program rules. |
| Massachusetts E-Title Transfer | Every joint seller must independently authenticate, approve, and release the vehicle. | Limited to qualifying private transactions between individuals. Business parties, active liens, branded titles, and power of attorney transactions are excluded. |
The Arizona examples illustrate why the name of an electronic service is not enough. Even within the same state, its in-state and out-of-state programs have different eligibility and participant requirements.
For a junk-car sale to a business, do not assume that an online process advertised for private sales is available. Massachusetts expressly excludes business parties from its E-Title Transfer program.
What if the Car Is Titled in One State but Being Sold in Another?
Identify both the state that issued the title and the state or agency that will process the incoming transfer.
The issuing state's rules are important, but the receiving jurisdiction may impose additional administrative requirements. Do not assume those requirements are identical.
For example, Maryland's MVA guidance, updated January 20, 2026, says its ordinary private-sale title can be signed by one owner when the title shows OR.
However, Florida's February 2025 FLHSMV Procedure TL-01 lists all signatures as required for a Maryland OR title in its out-of-state processing exhibit.
Interstate Transfer Verification Required
Those published instructions are not fully reconciled by the sources cited here. An owner attempting that specific interstate transfer should obtain guidance from the receiving Florida title office before relying on one signature.
The comparison table above must not be used to override a receiving agency's actual document requirements.
What if the Other Owner Cannot Sign?
The next step depends on whether the owner is merely unavailable, unwilling to participate, deceased, or legally unable to authorize the sale.
The Other Owner Agrees but Is Not Available
First confirm whether their signature is required.
If it is, ask the relevant title agency which methods it accepts. The co-owner might be able to sign the correct document separately or appoint an authorized representative where permitted.
Important questions include whether the agency requires an original endorsement, an approved form, notarization, identity verification, or direct electronic participation.
Do not rely on a text message, verbal permission, or photograph of a handwritten signature as a substitute for a required title endorsement unless the authority handling the transaction explicitly accepts that method.
Can You Use a Power of Attorney?
A power of attorney, or POA, can sometimes allow another person to sign an ownership-release document on a co-owner's behalf.
The California DMV power of attorney manual accepts appropriate general, restricted, and vehicle-specific POAs for certain ownership-release actions.
However, releasing title ownership and certifying the odometer reading are not automatically the same authorization. California has separate rules for odometer disclosure and certain secure POA procedures when applicable.
A POA also cannot substitute for the parties' direct participation in Massachusetts' qualifying online E-Title Transfer program.
Before arranging a POA, confirm that it is valid for the particular vehicle, signer, transfer method, and document.
The Other Owner Refuses to Sell
Do not treat a disagreement as a document inconvenience.
If both signatures are required, the sale cannot proceed through the ordinary two-owner endorsement process without the missing authorization or another legally valid basis.
Even where the DMV ordinarily accepts one owner's signature, an ownership agreement, divorce order, injunction, or other enforceable restriction may affect what that person is entitled to do.
A title office's acceptance of a signature is not a determination of every legal right between the co-owners.
Stop if Ownership Is Contested
If ownership is contested, stop the proposed transfer and consult an appropriately qualified attorney. Never imitate the other owner's signature or alter the certificate.
The Other Owner Has Died
Survivorship and estate authority become the controlling issues.
Arizona provides a useful example:
- With OR ownership, its instructions allow the surviving owner to transfer under the stated procedure without a death certificate.
- With AND/OR ownership, the survivor must provide the required death certificate before signing alone.
- With AND ownership, the deceased person's interest generally requires the applicable probate or qualifying non-probate process.
Other states use different designations and documentation. The ordinary living-owner signature matrix no longer provides a complete answer after a death.
The estate or survivorship procedure must be verified before transferring or releasing the vehicle.
Co-Owner Car Sale Readiness Record
Use this record before signing the title, accepting a buyer's closing instructions, or arranging vehicle collection.
It combines the relevant state rule with the actual circumstances of the proposed sale.
Step 1: Check the Eight Transfer Gates
Scroll horizontally to review the transfer-readiness record.
| Transfer gate | Evidence to verify | If the evidence is missing or unclear |
|---|---|---|
| 1. Title jurisdiction | State issuing the current ownership document | Find the issuing agency's official transfer instructions |
| 2. Owner names and wording | Exact names, conjunction, slash, JTRS, TOD or other designation | Confirm the ownership status before interpreting the required signatures |
| 3. Owner status | Both owners living, deceased co-owner, authorized representative, or disputed interest | Use the appropriate survivorship, estate, or legal-authority procedure |
| 4. Transfer method | Paper title, in-state electronic, out-of-state electronic, or another authorized process | Verify program eligibility and participant requirements |
| 5. Required participation | Correct original signatures, authenticated electronic releases, or acceptable representative authorization | Obtain the missing participation before executing the transfer |
| 6. Lien status | Whether a lien is recorded and what release or authorized closing process is needed | Contact the lienholder and relevant title office |
| 7. Buyer and document requirements | Buyer identity, assignment fields, disclosure forms, and any buyer-specific approval | Confirm the requirements before signing or releasing possession |
| 8. Legal restrictions | Known court orders, ownership disputes, estate restrictions, or other unresolved authority concerns | Stop the transfer and seek appropriate professional review |
Step 2: Classify Your Next Action
Ready for the Appropriate Transfer Process
The applicable authority is confirmed, required participants or authorized representatives can act, and the necessary documents are available.
Verification Required
The title wording, state procedure, receiving-state requirement, or electronic eligibility remains unclear. Contact the relevant title office before completing the paperwork.
Do Not Proceed
A required signer has not authorized the transfer, ownership is disputed, a court restriction may apply, or the proposed transaction lacks a lawful ownership path.
This is a seller preparation record, not an official title clearance, legal opinion, or guarantee that an agency will accept the transaction.
Step 3: Confirm the Actual Handoff
A DMV may accept a particular number of signatures while the buyer requires additional verification to complete its transaction.
For example, a vehicle buyer may request identification for each named owner, ask for a particular authorization document, or use a processing method that requires additional participation. Those business requirements should be identified before the sale, not discovered when the vehicle is being collected.
Do not assume Family Car Buyers or another purchaser can accept a missing signature, remote authorization, or unresolved lien without confirming its actual procedure.
Complete the Paperwork Before Releasing the Car
Once the signature question is resolved, the seller still needs to complete the applicable transfer documents accurately.
Confirm the Title and Vehicle Details
Check the VIN, names, ownership notation, and recorded liens. Where a vehicle requires a replacement title, use the issuing state's official replacement process.
If the problem is a missing certificate rather than uncertainty about joint signatures, the Family Car Buyers guide to junking a car without a title discusses related document questions. Its general guidance does not establish authority to sell someone else's ownership interest.
Complete Required Signatures and Disclosures
Use the correct seller-release fields and follow the agency's current instructions for buyer information, mileage disclosure, title brands, and other required statements.
Odometer disclosure requirements have exemptions based on the vehicle and applicable law. Do not assume every old junk car needs exactly the same mileage paperwork.
Nebraska's official transfer instructions warn that leaving purchaser information incomplete after signing creates an open-title problem and may violate state law.
Avoid signing unfamiliar fields in advance or altering completed entries without knowing the applicable correction procedure.
Confirm Payment and Possession Arrangements
Before turning over the keys, title, or vehicle, confirm the actual buyer, the agreed terms, the applicable payment verification procedure, and who is authorized to release the vehicle.
If the car does not run or is in a storage facility, the buyer must also know the location and collection restrictions.
A damaged or unwanted vehicle may qualify for a different lawful transfer or disposal process, but its condition does not automatically eliminate the rights of a titled co-owner.
Keep the Sale Evidence
Retain the completed transaction records you are legally permitted to keep, along with the buyer information, sale date, receipts, and applicable confirmation numbers.
File any required state sale or transfer notice and follow the local instructions for license plates and registration. For example, California provides a separate Notice of Transfer and Release of Liability process.
Filing a notice is not a substitute for completing the ownership transfer correctly.
Frequently Asked Questions About Selling a Jointly Titled Car
Can I sell a car if my spouse is the other owner?
You may be able to, but being married does not automatically let one spouse sign for the other. Check the actual title and the applicable signing rules. Nebraska, for example, expressly states that spouses cannot sign as agents for one another when completing an ordinary seller assignment. A separate authorization or court order may require its own procedure.
Do both owners have to be physically present?
Not necessarily. Requiring both signatures does not always mean both people must attend the same appointment. However, the state, title processor, or buyer may impose requirements concerning original endorsements, approved POAs, notarization, or authenticated electronic participation. Confirm these details before scheduling the handoff.
Can I sell a junk car if only my name appears on the registration?
Registration alone does not establish that you have authority to release title ownership. Obtain the current ownership record and identify the titled owner or authorized representative. A junkyard or buyer's willingness to accept the car does not independently establish a lawful transfer.
What if two names are listed without AND or OR?
Check for a slash or another designation. California uses a slash between co-owner names to indicate AND. If the document has unfamiliar or ambiguous wording, ask the issuing title agency how it interprets the recorded ownership before anyone signs.
Can I sell a car with an OR title without telling the other owner?
An agency may accept one signature under a particular state's ordinary title rules, but that does not resolve every possible agreement, court restriction, or dispute involving the co-owners. Confirm the legal and transaction circumstances rather than treating the conjunction as permission to disregard another person's enforceable rights.
What to Do Next
If you want to sell a car with two names on the title, first identify the issuing state and exact ownership wording. Then confirm who must sign, whether the selected transfer method is available, and what the receiving title office or buyer requires.
Resolve missing authorization before signing the title or releasing the vehicle. This can prevent a failed transfer and a dispute after collection.
If you own an old, damaged, junk, or non-running vehicle and have confirmed your authority to sell, you can request a vehicle evaluation from Family Car Buyers. Disclose any co-owner, lien, or title-document complication accurately.
Request a Vehicle EvaluationAn evaluation request does not guarantee a purchase, price, payment arrangement, or pickup. A transaction remains subject to acceptable ownership documentation and mutually agreed terms.
