Selling a car in the NT: disposal by email, 7-year roadworthy

In the NT, you and the buyer sign a notice of disposal, then you send it to the Motor Vehicle Registry (MVR) within 14 days of the sale by email, mail or in person, as there’s no online form. A roadworthy inspection is needed when ownership of a light vehicle 7 years or older is transferred, so a 2021 or newer car is still too young for that rule in 2026.

The roadworthy rule is easy to miss. At least one national car-selling guide, written in 2020, says the NT doesn’t make sellers furnish a roadworthy certificate. That can read as “no inspection needed”, but NT Government ties the inspection to the transfer itself, so on an older car it has to be sorted between you and the buyer. Every Territory rule here was checked against NT Government and Territory Revenue Office pages on 13 October 2026. Selling a car registered somewhere else? Our guide to selling a car in Australia covers every state.

Your NT sale, step by step

Is there an online form for an NT notice of disposal?

No. Most states let sellers notify online, but MVR has no online portal for disposals. NT Government’s seller responsibilities page lists four formats it accepts:

Whichever format you use, it must be signed by both you and the buyer, so plan the signing into sale day. If you’re unsure how MVR wants an emailed notice signed, the simplest route is to sign a written notice together on the day and email a scan of it.

What must the notice include?

MVR’s list is longer than a simple receipt. Your notice must include:

• your full name and address, and the buyer’s
• the buyer’s date of birth
• the date of sale
• the sale price or market value
• your signature and the buyer’s
• the rego number
• the make and model
• the VIN or chassis number
• the engine number

Two items catch sellers out. The buyer’s date of birth is personal, so some buyers hesitate. Tell them it’s an MVR requirement. The other is the engine number, which few owners know. If it isn’t in your paperwork, it’s usually stamped on the engine itself, and your mechanic or service centre can show you where. Write it down before sale day, not while the buyer waits.

On price, write the real figure. If you’re selling to a relative for less than the car is worth, ask MVR which figure to enter, because duty on a sale that isn’t at arm’s length is worked out on market value. Our list of documents needed to sell a car covers everything else to have ready alongside the notice.

How do you send it to MVR?

There are three ways:

• Email: send it to mvr@nt.gov.au. If your rego certificate is the notice, scan both sides.
• Mail: post it to GPO Box 530, Darwin NT 0801.
• In person: hand it in to MVR.

Email is the quickest, and your sent folder becomes a dated record. Post can take days, so don’t leave it until the end of your 14. Whichever way you send it, keep a copy of the signed notice and note the date it went.

You also need to give the buyer proof of ownership so they can apply for the transfer. NT Government says that after the sale, the seller “will no longer be responsible for any traffic infringement notices” issued for the vehicle. Your signed notice is the paper trail that shows when the car changed hands, so send it the day you sell rather than on day 14.

Does your car need a roadworthy before the transfer?

The main trigger is age. NT Government’s buying and selling page says a light vehicle 7 years old or older needs a roadworthy inspection when ownership is transferred. It also lists an inspection when a vehicle has been unregistered for 12 months or more, or is being registered in the NT for the first time. If either of those applies to your car, or you’re not sure, check with MVR what’s needed before you advertise.

Not every state ties the inspection to age. The ACT does (more than 6 years there), while Victoria and Queensland want a certificate on a private sale of a registered car, and NSW needs no pink slip to transfer a current registration. Here’s where common build years sit in October 2026:

MVR decides how age is counted for your car, so if yours is close to seven, check before you list it. If it does need an inspection and you’re selling privately, agree with the buyer who books it before you shake hands.

Most cars we buy are 2021 or newer, so the age trigger doesn’t reach them in 2026. When you sell to us, a roadworthy or safety certificate usually isn’t needed. Rules differ by state, and we confirm what applies to your car on the call.

What changes when you sell to a dealer?

Less than you might expect on your side of the paperwork. NT Government says licensed dealers must submit a notice of disposal to MVR when they sell or dispose of vehicles. That covers the dealer’s own sales. The pages we checked don’t move the seller’s notice onto the dealer, so plan on signing and sending yours as usual.

What shrinks is everything around it. When you sell to us, we prepare the sale paperwork and help with the transfer of ownership, and we’ll make sure your notice of disposal is done correctly.

What happens to your number plates?

In the NT, the plates aren’t yours. NT Government says all plates, general and personalised, belong to MVR. What you hold is the right to display them, and that right can be transferred. NT Government describes three situations where that happens:

• you sell the car with the plates attached, so the right to display goes to the buyer
• you keep the plates for another vehicle you own
• you swap plates

Decide before you agree a price, and tell the buyer which it is, especially if you’re keeping a personalised plate for another car. NT Government’s right-to-display page covers each option, so read it before sale day.

Should you sell it registered or unregistered?

NT Government says sellers can choose to sell a vehicle unregistered and check whether they can get a rego refund. Before you cancel anything, weigh up three points:

• A private buyer who wants to drive the car home will want it registered.
• NT Government lists an inspection for a vehicle unregistered for 12 months or more, so don’t let it sit for long.
• A refund isn’t automatic. Check with MVR whether you’re eligible before you decide.

If you’re selling to us, raise it on the call before you cancel the rego. We arrange collection, so the car doesn’t have to be driven anywhere by you.

What does the buyer pay?

The buyer applies to transfer the registration within 14 days and pays the transfer fee and stamp duty. Neither comes out of your pocket.

The Territory Revenue Office charges stamp duty at $3 for every $100, or part of $100, of the dutiable value, as at October 2026. The dutiable value is usually the sale price, including accessories, any trade-in allowance and dealer delivery. When the sale isn’t at arm’s length, it’s the market value.

The “or part” wording means any amount past a round $100 counts as a full $100. Here’s a worked example with hypothetical sale prices:

Compared with a flat 3%, the rounding adds less than $3. If a buyer asks you to write a lower price on the notice to cut their duty, say no. You sign that notice, and the price on it should be the real one.

What will a careful buyer check before paying?

A careful buyer runs a PPSR search on the VIN before handing over money. For $2 online (as at October 2026), it shows any security interest, meaning money owing, and usually the car’s written-off and stolen status too. Run one yourself first so nothing surprises you on the day. A buyer may also compare the VIN and engine number on the car with the ones on your paperwork, which is one more reason to get the engine number right on your notice.

If you still owe money on the car, the lender’s interest shows on the PPSR, and a private buyer will want it cleared before they pay. When you sell to us, we deal with your lender directly to pay out the loan, then pay any equity to you. Settlement usually takes 2 to 3 business days, and any negative equity has to be covered before settlement. Our page on selling a car under finance explains the steps.

What changes if the buyer is interstate?

Plan on the same paperwork. You still need the buyer’s signature on the notice, and you still send it to MVR within 14 days, wherever the buyer lives. If you never meet the buyer, arrange for them to sign the notice and send it back before the 14 days run out. Our guide to selling your car to an interstate buyer covers how each state handles it.

What changes is the distance, and long gaps between payment and pickup are where private sales go wrong. Scamwatch lists a buyer willing to buy without seeing the car in person as a warning sign. It also flags overpayments followed by a refund request, payments split across several PayIDs, and an account name that doesn’t match the buyer. Never release the car to a carrier until the full amount has cleared in your account. An email saying the money is on its way isn’t the money.

Selling to us takes the transport off your list. We arrange collection anywhere in Australia, including the NT. The order never changes: a genuine offer by phone, a deposit (often the same day), an inspection at a time and place that suits you, then the balance into your bank account. The car is collected only after you confirm the funds have cleared. Our guide to car collection and key drop-off explains how collection day runs. As Ray Murray put it: “I had tried to sell it privately for some weeks but was only contacted by scammers and ridiculous offers. Dean offered me a fair price.”

Private buyer or dealer: what’s left for you?

Sell privately in the NT and every step above is yours: the age and rego checks, the plates, the buyer’s checks, safe payment, two signatures and the notice to MVR. Sell to us and we prepare the sale paperwork and help with the transfer of ownership. That leaves you to decide about your plates and to sign and send your notice of disposal, and we’ll make sure it’s done correctly.
