Selling a car in joint names or registered to your partner

Key takeaways
- The NSW Government says a rego certificate shows who is responsible for a car, not who owns it. Plan on everyone named on the registration signing the sale.
- In the ACT both registered operators sign the transfer and disposal sections. In WA a jointly owned car, or a transfer between spouses or de facto partners, can't go through DoTDirect and needs the paper MR9 form.
- On a joint loan you are each liable for the whole debt, and a secured lender is paid out first. Ask your lender what it needs from each borrower.
- Agree in writing how the money will be split, and whose account it goes into, before you accept an offer.
If a car is registered in two names, plan on both of you signing the sale paperwork. If the loan is in both names, you are both liable for it, so check with your lender what it needs from each borrower before it’s paid out. And if the car is registered only to your partner, your partner is the seller on paper and signs, unless they’ve given you legal authority to sign for them.
The detail depends on three separate records that don’t always match, and on which state the car is registered in. This guide covers the mechanics for couples, parents and adult children, and anyone else sharing a car. If you’re selling because you’ve separated, our page on selling a car after a separation deals with that situation directly.
Who actually owns a car in two names?
Three different records say something about a car, and they can point at different people.
| Record | What it shows | Who it involves |
|---|---|---|
| Registration | Who is responsible for the car on the road | The registered operator or operators |
| Loan contract | Who owes the money, often with the car as security | Every borrower on the loan |
| Receipt or contract of sale | Who bought the car | The owner or owners |
It’s easy to assume the registration settles it. It doesn’t. The NSW Government’s guide to buying a used car says the Certificate of Registration “shows only the person who takes responsibility for the vehicle, it does not prove ownership”. The same page calls the receipt the only proof that you own the vehicle.
WA shows how far apart these can sit. When a vehicle is jointly owned there, the MR9 transfer form from the Department of Transport and Major Infrastructure (DTMI) says all the owners sign a proof of identity form (the VL186) nominating one owner as the licence holder. That’s two owners and one nominated licence holder.
The Personal Property Securities Register (PPSR) won’t settle it either. A PPSR search shows whether a lender has a security interest over the car, but it doesn’t show who owns it.
So a two-name sale needs three groups to line up. The people on the registration sign the transfer. The borrowers deal with the lender. Anyone else with a genuine ownership share agrees before anything is signed.
Who has to sign when two names are on the rego?
Each state records a sale its own way. The ACT spells out what happens when two names are on the rego, and WA has rules that matter whenever partners or joint owners are involved.
Access Canberra says the transfer and notice of disposal on the back of the rego certificate are completed by “you (and the other person if it’s jointly operated)”, along with the buyer. If you notify online, a car registered in two names needs one submission that includes both operators’ ACT driver licence details. The online form also asks for the buyer’s ACT licence number. When the buyer doesn’t hold one, the notice goes in through the ACT Digital Account, by mail or in person.
In WA, as above, a jointly owned car has one nominated licence holder. DTMI’s transfer fact sheet lists jointly owned vehicles, and transfers between spouses or de facto partners, among the transfers that can’t be done online through DoTDirect. Those go on the paper MR9 form, which isn’t valid unless the seller and the purchaser both sign it. The seller’s blue copy has to reach DTMI within 7 days, or a penalty applies. If your car is jointly owned, ask DTMI whether the other owner needs to sign as well. Our guide to selling a car in WA walks through the form.
| State or territory | What the official source says | What to do |
|---|---|---|
| ACT | Both registered operators complete the transfer and disposal sections, with the buyer | Both of you sign; an online notice needs both ACT licences in one submission |
| WA | Jointly owned cars and transfers between partners can’t go through DoTDirect; they need the paper MR9 | Seller and buyer sign the MR9; the seller’s blue copy is due within 7 days |
| QLD | Online transfer only works when the rego goes to one person; the in-person form F3520 is signed by buyer and seller | Ask Transport and Main Roads whether your sale can go online; if not, transfer in person with the F3520 |
| NSW | The rego certificate doesn’t prove ownership; the online notice of disposal needs the seller’s NSW licence or Photo Card | Ask Service NSW how to lodge for two operators |
| VIC, SA, TAS, NT | The seller’s disposal notice is due within 14 days (VIC, SA, NT) or 7 days (TAS) | Ask the transport authority how two sellers sign |
Whatever the state, follow the advice that NSW and Victorian guidance both give: don’t sign anything that transfers ownership until you’ve been paid.
What if the car is only in your partner’s name?
Then your partner is the seller as far as the transport authority is concerned, even if you paid for the car or drive it every day. In NSW, for example, the online notice of disposal is lodged through the seller’s own MyServiceNSW Account, with their NSW licence or Photo Card details. Being a couple doesn’t let you sign for them.
You have three practical options.
- Your partner signs. This is the simplest route. They need photo ID and to be available when the paperwork is signed.
- You sign under a power of attorney. You need a power of attorney that covers financial matters and is still in force. A general power of attorney stops working if your partner can no longer make their own decisions, and an appointment that covers only health or medical decisions doesn’t let you sell. Our guide to selling a car with power of attorney explains which documents count.
- Transfer the car into your name first. This adds a step and can cost duty. In NSW, giving a car to a spouse or partner means submitting a notice of disposal, and your partner then transfers the registration. Service NSW says a duty exemption may apply in some situations. In WA, a transfer between spouses or de facto partners has to go on the paper MR9 form, and the MR9 says an exemption from duty may be available between spouses or de facto partners of at least two years.
If you believe you own part of a car but your name isn’t on anything, keep your receipts and bank records. Get legal advice before the car is sold, not after.
Do both borrowers have to agree to sell a car on a joint loan?
What’s needed from each borrower depends on your lender and your loan contract, so check with your lender first. Two things hold whatever it says. A loan secured against the car has to be paid out at or before the sale, because the lender’s interest shows on a PPSR search and careful buyers search the PPSR before they pay. And until the loan is paid out, you both owe it. Moneysmart’s guidance on shared loans is blunt: you are both responsible for repaying the debt, and if one of you doesn’t pay, the other must pay the full amount.
Before you agree a sale, ask your lender:
- Can one borrower request the payout figure, or does it need both of us?
- Do both borrowers have to authorise the payout?
- Is there an early termination fee, and is it in the payout figure?
- If someone is a guarantor rather than a borrower, do they need to be told?
This matters when a parent helped with the loan. Moneysmart defines a guarantor as someone who is legally responsible for paying another person’s debt if that person can’t. That’s a different role from a co-borrower, so check which one your parent or partner actually signed up as.
When you sell to us, we deal with your lender directly to pay out the loan, then pay any equity. It usually takes 2 to 3 business days to settle. If you owe more than the car is worth, the negative equity has to be covered before settlement. Our page on selling a car under finance covers each step.
Who signs what: a quick decision guide
Find your situation, then settle the right-hand column before sale day.
| Your situation | Who takes part | Settle this first |
|---|---|---|
| Both names on the rego, no loan | Both registered people, plus the buyer | How your state wants a two-name sale lodged |
| One name on the rego, loan in both names | The registered person for the transfer; the borrowers, as the lender requires | The payout figure and what the lender needs from each of you |
| Car in your partner’s name only | Your partner, or you with a financial power of attorney | A time your partner can sign |
| Parent is a co-borrower or guarantor | Whoever the lender says must be involved | What your lender requires |
| One registered operator has died | The surviving operator; in NSW, once the rego is transferred to them | Proof of death, and how your state moves the rego to the survivor |
On the last row, NSW is specific. Service NSW lets the surviving joint registered operator take over the rego at a service centre with their proof of identity, a transfer application and proof of death, such as the death certificate. It says no additional documents are required, and there’s no transfer fee or stamp duty for this type of transfer. The rego still isn’t proof of ownership, so if the other owner’s share passes through their estate, check with the executor before you sell. Our guide to transferring a car after someone dies covers the rest of the process.
How do you split the money from a jointly owned car?
If there’s a loan secured against the car, the lender gets paid first. Whatever is left is the equity, and how you divide it is your agreement to make, not the buyer’s.
Here’s a worked example with hypothetical numbers. Say a car on a joint loan sells for $40,000, and the lender’s payout figure, including interest to the settlement date, is $16,000. That leaves $24,000 in equity.
| How you agree to split | Person A | Person B |
|---|---|---|
| Equal shares | $12,000 | $12,000 |
| A gets back the $6,000 deposit they paid, then equal shares | $15,000 | $9,000 |
| By share of repayments made, say 60/40 | $14,400 | $9,600 |
Now flip it. If the same car sells for $40,000 but the payout figure is $43,000, there’s a $3,000 shortfall. On a joint loan, each of you is liable for all of it, as Moneysmart’s shared-loans guidance above explains. When you sell to us, negative equity has to be covered before settlement, so agree who is putting it in before you accept an offer.
Three habits stop the money turning into an argument:
- Put the split in writing, signed by both of you, before you accept any offer.
- Decide whose bank account the balance goes into, and how the other person receives their share.
- Raise it on the valuation call, so everyone knows how payment will work before anything is signed.
What if the other owner can’t or won’t sign?
If they simply can’t be there, because of work, travel or a move overseas, the fix is timing or paperwork. Agree a day you can both sign, or have them grant a financial power of attorney while they can still make their own decisions. Check what the transport authority accepts before you set a date.
If they won’t sign, don’t try to sell around them. A car that someone else part-owns isn’t yours alone to sell. Signing without the other registered person can leave you with a bigger dispute than the one you started with. Talk to a family lawyer or your state’s Legal Aid service first, especially if you’re separating.
What documents should you have ready?
Gather these before sale day, covering everyone involved:
- Photo ID for each person who will sign
- The current registration papers
- Details of any loan in either name: the lender, the account number and a current payout figure
- Any power of attorney or estate documents, with copies
- Your signed agreement on how the money will be split
- Bank details for the account the balance is going into
- The service logbook, receipts and every key
Our guide to the documents needed to sell a car covers the rest, state by state.
Selling a two-name car to us
Two names mean more signatures, not a different process. Tell us on the call whose names are on the registration and on any loan, so everyone who needs to sign is lined up before sale day.
Sell Your Car Australia is run by Autohaus Australia Pty Ltd, NSW licensed motor dealer MD 077404, and our valuer has priced cars since 1992. You get a genuine offer by phone from a licensed dealer, not an online estimate. Once you accept, a deposit is often paid the same day, and the inspection follows at a time and place that suits you. The balance is paid into your bank account, and the car is collected only after you confirm the funds have cleared. We prepare the sale paperwork and help with the transfer of ownership, and we arrange collection anywhere in Australia.
We buy cars, utes, SUVs and 4WDs 2021 or newer with 100,000 km or less. If yours is older or has more kilometres, send it through anyway and we’ll tell you straight away if we can help. The valuation is free, with no obligation and no fees taken out of the offer. Call 1800 73 55 73 to start.
Questions sellers ask
Can I sell a car that's in my partner's name?
Not on your own signature. Transport authorities treat the registered operator as the seller, so your partner signs the sale paperwork and records the sale with the transport authority. The exception is a financial power of attorney that is still in force, which lets you sign for them. Being married or in a de facto relationship doesn't give you that authority by itself.
Do both borrowers have to agree to sell a financed car?
If the loan is secured against the car, it has to be paid out for the sale to go through cleanly, and on a joint loan you are both responsible for the whole debt. Who can request the payout figure and authorise the payout is up to your lender, so check with it before you accept an offer. If one borrower won't cooperate, get legal advice before going further.
Who gets the money from a jointly owned car?
If there's a loan secured against the car, the lender is paid first. What's left is yours to divide however the two of you agree, whether that's equal shares or a split based on who paid the deposit or the repayments. Put the agreement in writing and decide whose account the balance goes into before anything is signed.
Can I take my partner's name off the rego before we sell?
It's an extra transaction with the transport authority, and it doesn't change who owns the car or who owes the loan. Changing who is on the rego generally goes through your state's transfer process and can involve duty, so ask the transport authority how it handles it. In WA, a transfer between spouses or de facto partners has to go on the paper MR9 form, and the form says a duty exemption may be available between spouses or de facto partners of at least two years. For most couples it's simpler for both of you to sign the sale itself.
What if the loan is in my name but the car is registered to my partner?
Then you both have a part to play. You deal with the lender as the borrower, starting with the payout figure. Your partner signs the sale paperwork as the registered operator. Line both up before sale day so neither holds up the other.
