Why you should have a contract to buy or sell your next car
Buying or selling a vehicle often happens quickly - messages, a test drive, a handshake. That speed creates risk: unclear promises, last-minute changes, financing surprises, or disputes after handover. A short, written contract removes ambiguity and sets out exactly what each party must do and when. This matters because vehicle transactions involve high values, legal ownership, safety obligations, and liabilities that can follow the car - and you - after the sale. The solution is simple: use a clear, plain-English sale contract and follow a disciplined settlement process.
The case for a written contract
Clarity: Defines the vehicle, price, condition, inclusions, and timing - no guesswork.
Proof: Creates a record for registration, insurance, and resolving disputes.
Risk control: Addresses title, existing finance, defects, and non-payment.
Compliance: Aligns with identity checks and transfer requirements in your state/territory/country.
Efficiency: A standard template reduces negotiation time and prevents last-minute confusion.
When a contract is essential
Private sales (no dealer protections).
Vehicles with outstanding finance or complex histories (e.g., repairs, modifications).
Remote or interstate transactions.
When the deal involves deposits, delayed pickup, or conditional terms (e.g., subject to inspection).
Any sale where either party wants clear evidence of what was agreed.
Risks of not having a contract
Payment disputes: No clear evidence of what was owed, when, and how.
Hidden encumbrances: Buyer inherits problems from unpaid finance.
Condition disagreements: No record of what was disclosed or included.
Registration issues: Delays or fines due to unclear responsibility for paperwork.
Limited recourse: Hard to enforce promises made only by text or conversation.

Parties & verification
Full legal names, addresses, contact details, and agreed method for verifying identity.Vehicle details
Make/model, year, VIN/chassis, registration plate, odometer reading at handover, and any identifiers for accessories.Title & encumbrances
A seller warranty that they own the vehicle outright or will clear any finance before or at settlement, with a method for confirming this (e.g., official register search).Price & payment method
Total price, deposit amount (if any), when due, and settlement method (e.g., bank transfer, escrow, secure simultaneous settlement). State clearly who pays any transfer fees.Condition & disclosures
“As-is” sale or specified warranty; known defects; accident history; non-standard modifications; service history provided; number of keys; included accessories (e.g., roof racks, chargers).Inspections & tests
Whether a pre-purchase inspection has been completed or is a condition precedent to the sale.Registration, roadworthiness, and compliance
Who is responsible for obtaining safety/roadworthy certificates (if required) and lodging transfer forms.Handover details
Date, time, location, and what must be exchanged: payment confirmation, signed forms, keys, manuals, service records.Risk & liability
When risk passes to the buyer (typically on handover); insurance responsibility before and after handover.Cooling-off or contingencies (optional)
Any agreed right to cancel (e.g., finance approval failure) and how deposits are treated.Dispute resolution
Practical first steps (discuss, then written notice) and the governing law/jurisdiction.Signatures & acknowledgements
Dated signatures (electronic or physical), with acknowledgement that both parties read and understood the terms.
A safe settlement workflow (recommended)
Pre-agreement
Exchange IDs and confirm contact details.
Share service history and disclosures.
Run a title/encumbrance check on the vehicle.
Agree the price and terms in writing (draft contract).
Deposit (if used)
Keep it modest and subject to the stated conditions (e.g., inspection).
Specify refund/non-refund circumstances.
Final checks
Re-run title check close to settlement.
Confirm outstanding finance payout figure (seller) and the method to clear it at settlement.
Simultaneous exchange
Payment is made at the same time title transfer paperwork is completed.
Keys, signed documents, and payment confirmation change hands together.
Post-handover
Buyer arranges insurance effective from handover time.
Parties lodge transfer/notification forms promptly.
Keep the signed contract and receipts.
Common mistakes to avoid
Relying on a “sold as-is” note without specific disclosures.
Not matching ID names to the registered owner or finance documents.
Paying in full before confirming title is clear.
Missing the exact odometer reading and handover timestamp.
Skipping a pre-purchase inspection or roadworthy where required.
Forgetting to state who pays transfer and government fees.
