Two people bought the car together, so both names went on the title. Years later one of them tries to sell it, and discovers that whether they can do it alone was decided by a single word printed between their names.
The word that decides it
Pennsylvania titles join co-owners with a conjunction, and that conjunction is not decoration. It is the rule for who has to sign.

| Printed as | Who must sign to transfer | Effect |
|---|---|---|
| Owner A and Owner B | Both owners | Neither can act without the other |
| Owner A or Owner B | Either owner alone | Either can act independently |
| Owner A and/or Owner B | Both owners, in practice | Treated as requiring both |
Read your own title rather than relying on a general rule. Wording and instructions vary, and the consequence of getting this wrong is not a delay — it is a signature in the wrong place on a document that voids when altered. If the conjunction is unclear, bring the title in and have it read before anyone signs anything.
Why it matters more than people expect
Every Pennsylvania title transfer requires the assignment to be notarized, so “both owners must sign” means both owners must physically appear before a notary, with identification.

That is straightforward when the co-owners are a couple living in the same house. It becomes a genuine obstacle when they are a parent and an adult child in different states, a formerly married pair, or two people who no longer speak.

The trade-off, honestly
Neither form is simply better. They protect different things.
| ‘And’ title | ‘Or’ title | |
|---|---|---|
| Convenience | Lower — both must attend | Higher — either can act |
| Protection | Higher — neither can sell alone | Lower — either can sell alone |
| If the relationship sours | Neither party can act unilaterally | Whoever moves first controls the outcome |
| If one owner is abroad | Transfer blocked without a POA | The other proceeds normally |
| Best suited to | Co-owners protecting an investment | Family members who trust each other |
The uncomfortable version of the ‘or’ risk is worth stating plainly: on an ‘or’ title, one co-owner can sell the vehicle without the other’s knowledge or consent. That is not a loophole — it is what the conjunction means.

When a co-owner cannot attend
On an ‘and’ title, a missing owner stops everything. The solution is a power of attorney, and Pennsylvania has a specific one for vehicle transactions rather than relying on a general document.
That form has its own requirements and its own notarization rules, set out in vehicle power of attorney in Pennsylvania. Arranging it in advance is far easier than discovering the need on the day a buyer is waiting.
When a co-owner dies
Joint ownership frequently exists precisely so that the survivor keeps the vehicle without difficulty, and Pennsylvania supports that.

Where right of survivorship applies, the surviving owner transfers the vehicle with a certified death certificate, a properly completed Form MV-39, and the title signed by them. Between spouses, right of survivorship is implied — it does not have to be stated separately.
Where the co-owners were not spouses, how the names were joined matters again, and the estate may need to be involved. The full picture, including the fee waiver available to a surviving spouse, is in transferring a car title after someone dies in Pennsylvania.
Decide at purchase, not at sale
This is the practical lesson. The conjunction is set when the title is issued, and changing it later is a fresh transaction rather than a correction — you cannot amend a title, because any alteration voids it.

So the question is worth asking at the counter, while the paperwork is being prepared:
- Who is actually paying for this vehicle?
- Does the second name serve a purpose, or is it habit?
- If one of us needed to sell without the other, should that be possible?
- If one of us died, what should happen to the car?
- Are we both realistically available to attend a notary in future?
A parent adding themselves to a young driver’s title for control wants ‘and’. A married couple who simply want either of them to be able to handle it usually want ‘or’. Both are reasonable; the mistake is not deciding.
One thing joint titling does not do
Adding someone to a title does not affect their credit, help them build it, or make them liable for the loan. A title records ownership. A loan agreement records debt. They are separate documents and being on one says nothing about the other.
People occasionally add a name for credit reasons and end up with a co-owner they did not intend and cannot easily remove. If the goal is financing, that conversation belongs with the lender rather than the titling counter.
Insurance is a separate question again. Who is named on the title does not determine who is covered to drive the vehicle — that is set by the policy, and a regular driver should be listed on it regardless of whose name appears on the title.
We read titles with customers before anything is signed, and process transfers, survivorship applications and new titling at our Bethlehem title transfer service. PennDOT’s guidance for both sides of a transaction is in its buying or selling your vehicle fact sheet.
Frequently asked questions
If two names are on a PA title, do both have to sign?
It depends on the conjunction. If the names are joined by ‘and’, both owners must sign. If they are joined by ‘or’, either owner can sign alone. ‘And/or’ is treated in practice as requiring both.
Which is better, and or or?
Neither is universally better. ‘Or’ is convenient because one owner can act alone, and risky for the same reason. ‘And’ protects both parties by requiring agreement, at the cost of needing both people present for anything.
What if my co-owner cannot come to the notary?
On an ‘and’ title, the transfer cannot proceed without them unless they grant a power of attorney authorising someone to sign. Pennsylvania has a specific vehicle power of attorney used for exactly this.
What happens if a co-owner dies?
Where right of survivorship applies, the surviving owner can transfer the vehicle with a certified death certificate, a properly completed Form MV-39, and the title signed by them. Between spouses, right of survivorship is implied.
Can I change the conjunction on an existing title?
Not by writing on it — any alteration voids a Pennsylvania title. Changing how ownership is held means a new title application, which is a transaction in its own right. Ask before assuming it is simple.
Does adding my child to the title help them build credit?
No. A vehicle title records ownership, not credit. Being named on a title has no effect on a credit file, though being named on the loan does — those are two different documents.
