Selling a car is usually pretty straightforward—until you’re doing it for someone else. Maybe your mum’s no longer driving, your sibling moved overseas, or a loved one has passed away. Whatever the situation, selling a car on behalf of a family member comes with a few extra steps and legal bits you need to get right.
But don’t worry—it’s manageable. In this guide, we’ll walk you through what to do, what paperwork you’ll need, and how to avoid any complications.
When Would You Need to Sell a Car for Someone Else?
Here are a few common scenarios:
- A parent or grandparent has stopped driving due to age or health
- A family member moved interstate or overseas and left the car behind
- A partner or spouse asked you to sell their car because they’re too busy
- You’re handling someone’s estate after they’ve passed away
Each case is a little different, but the core process is similar: prove ownership, complete the paperwork correctly, and make sure the sale is legal.
Step 1: Make Sure You Have the Legal Right to Sell
If the car is in someone else’s name, you can’t just sell it as if it were your own. You’ll need to show that you have permission to act on their behalf.
Here’s how it works depending on the situation:
If the owner is alive:
You’ll need a signed authorisation letter from them. It should include:
- Their full name and contact details
- A statement giving you permission to sell the vehicle
- Details of the car (make, model, rego, VIN)
- Their signature and the date
It’s also a good idea to attach a copy of their driver’s licence and yours.
If you’re acting under power of attorney:
If the owner is unable to manage their own affairs, and you have legal power of attorney, you can sell the vehicle. Just be ready to show the original or certified copy of the POA document.
If the owner has passed away:
Things are a bit more sensitive here. If you’re the executor or next of kin, you’ll need:
- A death certificate
- Proof you’re the executor or administrator of the estate
- Vehicle details and registration papers
- ID matching the name on the estate documents
Some states may also ask for a completed ‘Transfer of Registration by Executor or Administrator’ form.
Step 2: Check the Car’s Status
Before you go listing the car online or getting offers from dealers or cash-for-cars services, check:
- Is the registration current?
- Is there any finance owing? (You can check this using the PPSR – Personal Property Securities Register.)
- Does it need a roadworthy certificate?
This step saves headaches later—no buyer wants surprises.
Step 3: Choose How You Want to Sell It
You have a few options when selling on someone else’s behalf:
- Private sale – Takes more time, but can fetch a higher price
- Dealer trade-in – Easy, but usually offers a lower value
- Cash for cars service – Fast, no paperwork stress, and no need for RWC
If time and convenience matter most—especially if the car is old, damaged, or not being driven—a car removal or cash-for-cars service can take care of everything in one go.
Step 4: Handle the Paperwork Properly
Even though you’re not the registered owner, you’ll still need to fill out:
- A transfer of registration form (most states allow third-party submission with proof of authorisation)
- A Notice of Disposal (in the seller’s name, to avoid future fines or tolls)
- A receipt or bill of sale for your records
If using a car removal service, they often help complete the documents with you on pickup day.
Real-Life Example:
One of our customers recently contacted us to sell her late father’s old Ford Falcon. She had the death certificate and probate paperwork, but wasn’t sure where to start. We guided her through the process step by step—no roadworthy needed, and we handled all the paperwork on-site. The car was gone the same day, and she was paid cash on the spot. Simple and stress-free.
A Few Final Tips
- Don’t fake a signature or guess your way through forms—it’s not worth the legal trouble.
- Always keep a copy of any paperwork you submit.
- Check state-specific rules—VicRoads, Service NSW, and other road authorities each have slightly different requirements.
