Bill of Sale — What It Is & How to Create One

Updated 12 Mar 2026Content was accurate at the time of publication

A bill of sale (also called a sale receipt or transfer of ownership document) is one of the simplest documents that can protect you from costly disputes — yet many sellers and buyers skip it or fill it out poorly. This practical guide explains what a bill of sale is, when you need one, and gives a step-by-step workflow for drafting a legally effective bill of sale for private and business transactions — with emphasis on used car bill of sale, boats and other personal property.

What is a bill of sale?

A bill of sale is a written record that documents the transfer of ownership of personal property from a seller to a buyer. It serves three primary legal functions:

Evidence of sale — proves that a transaction occurred and records key terms (price, date, parties).
Receipt of payment — confirms payment or explains the payment schedule (deposit, instalments).
Transfer of title for unregistered goods — for many items (furniture, tools, machinery) the bill is the main proof of ownership.

A bill of sale is distinct from:

A registration or transfer form used by transport registries — registration changes records with the road authority but does not replace a bill of sale.
A simple receipt — receipts often lack key representations (e.g., "no encumbrances") that a bill of sale includes.
A contract of sale — a contract can be broader (warranties, delivery terms). A bill of sale can be a concise contract or a receipt-style document depending on how you draft it.

When and why you should use a bill of sale

Use a bill of sale whenever you transfer ownership of tangible personal property or want written proof of the deal. Typical use cases:

Private vehicle sale (used car, motorcycle): documents sale price, odometer reading and "as-is" condition.
Sale of equipment or machinery: clarifies serial numbers, service history and warranties.
Boat or trailer sale: captures registration details and safety certificates.
Instalment sales or deposits: records deposit receipt and repayment conditions.
Business asset disposals: records disposal price for tax and asset registers.

Benefits:

Reduces risk of disputes about price, condition, or ownership.
Provides evidence for tax records and GST calculations.
Helps protect sellers from liability after transfer (with clear "as-is" wording).

Essential elements every bill of sale must include

A legally effective bill of sale is clear, complete and specific. At minimum include:

Full legal names and contact details of seller and buyer (include identification type and number).
Addresses for both parties.
Date of sale.
Detailed description of goods:
- For vehicles: make, model, year, VIN/Chassis number, registration plate, odometer reading and date.
- For machinery/boats: serial number, hull ID, engine hours, relevant certificates.
Sale price (total), payment method and currency (AUD), and whether GST applies.
Receipt of payment or deposit amount and balance due.
Warranties and condition: explicit "as-is" clause if no warranties; specify any express warranties.
Encumbrances statement: seller declares whether the goods are free of liens or security interests.
Delivery and risk: when title and risk pass to buyer (on payment, on delivery, etc.).
Signatures of seller and buyer and date of signing. Witness block if required.
PPSR note: advise parties whether a PPSR search was done and include registration details if an interest was lodged.

Step-by-step: How to write and complete a bill of sale

Follow this practical workflow from pre-sale checks to final record-keeping.

Pre-sale checks (do these before you sign or accept money)

Verify identities: ask for driver licence or passport and copy the ID block into the bill of sale.
Run a PPSR check to identify registered security interests: visit https://www.ppsr.gov.au. Record the search reference in the bill.
Verify VIN/serial/engine numbers and inspect condition (photos are helpful).
Check registration history and any outstanding recalls via the vehicle registry. See the state registry guide such as https://www.service.nsw.gov.au/guide/selling-a-vehicle.
If you're a business seller, confirm GST obligations and invoice numbering. See ATO guidance at https://www.ato.gov.au.

Drafting the bill

Use clear headings and numbered clauses.
Use precise descriptions — VINs and serial numbers reduce later disputes.
State payment terms: deposit amount, due date for balance, acceptable methods (bank transfer, cleared funds).
Include an "as-is" clause or detail any warranties.
Note who pays for transfer costs, registration transfer fees, stamp duty, or inspection costs.

Execution and exchange

Witnessing: have an independent adult witness sign.
Payment: prefer cleared bank transfer or bank cheque. For deposits, provide a signed receipt section in the bill.
Handover: hand over keys, registration papers, user manuals and any service records once the agreed payment conditions are met.
Keep copies: both parties should keep signed originals (scan and email copies are also useful).

Record-keeping

Retain the bill of sale and supporting evidence (PPSR search results, photos, payment receipts) for at least 5 years for tax and warranty queries.
Update asset registers if you are a business; record disposal in your accounting system and reconcile GST or CGT effects.

Vehicle, boat and registered goods — post-sale steps and transfer of registration

A bill of sale transfers ownership but does not automatically transfer registration. You must complete the registry's transfer process to update the registration record and avoid liability.

Complete the required transfer form from the relevant state/territory transport authority. Example guidance: https://www.service.nsw.gov.au/guide/selling-a-vehicle.
Provide the buyer with a copy of the bill of sale, registration papers, and any safety/roadworthy certificate that may be required.
Record the odometer reading and date on the transfer form if required.
Timeframes: Most registries require notification within a set number of days after sale. Check the relevant transport authority web page for exact timelines.
Insurance: the seller should cancel or notify their insurer of the sale; the buyer should insure the vehicle from the moment risk passes.

PPSR (Personal Property Security Register) — check and register interests

The PPSR records security interests (loans where the asset is collateral). For most buyers and sellers a few practical steps are enough:

Why search the PPSR: to confirm there are no registered security interests (encumbrances) against the item you intend to buy.
How to search: run a VIN/serial search at https://www.ppsr.gov.au. Save the search receipt and include the search reference in the bill of sale.
If a financing statement exists: do not complete the sale until the interest is discharged or you have cleared funds and written discharge evidence.
Seller protections: if you accept instalments and want to retain security, register a PPSR financing statement and record that interest in the bill.

For more information on the Personal Property Securities Register, visit the PPSR website.

Tax and pricing considerations

Tax rules vary depending on whether the seller is a private individual or a GST-registered business.

Private sellers: generally do not charge GST on the sale of personal items and the sale is treated as a capital disposal (CGT may apply only in unusual circumstances, e.g., sale of collectibles or investment assets).
Business sellers: if you are registered for GST and selling business assets, GST may apply. Use proper invoices and record GST amounts — see ATO guidance at https://www.ato.gov.au.
Documenting price and deposits: always record whether the price is GST inclusive or exclusive, and issue invoices where required.
Capital Gains Tax (CGT): high-value or investment disposals may trigger CGT — keep accurate records of purchase cost, improvements and sale proceeds.
Record keeping: retain bills of sale, bank statements, and supporting documents for tax reporting.

If the buyer requires finance to complete the purchase, they can explore options such as personal car loans or business asset financing for commercial purchases.

Witnessing, notarisation and legal formalities

Most bills of sale do not require notarisation. Consider witnessing or notarisation when:

The sale is high value.
The parties want independent evidence of signature authenticity.
State rules require additional formalities (rare for simple goods).

Best practice for witnessing:

Use an independent adult witness (not a party to the sale).
Record witness name, contact details and ID type.
Witness signs and dates the document at the same time as the seller or buyer.

Notarisation is uncommon for routine private sales but may be useful when parties are overseas or where extra authentication is needed. Check your state fair trading or registry guidance such as https://www.fairtrading.nsw.gov.au.

Common clauses and sample wording (short library)

Below are short, ready-to-copy clauses. Adapt to your sale and consider legal review for complex deals.

As-Is clause:

"The Buyer acknowledges that the Goods are sold as-is and that the Seller gives no warranties, express or implied, except where expressly set out in this document."

No encumbrance:

"The Seller warrants that at the date of this Sale the Goods are free of all security interests, charges and encumbrances and the Seller has full right to sell the Goods."

Deposit/Settlement:

"A deposit of $1,000 has been paid by the Buyer by bank transfer on 15/01/2025. The balance of $1,500 is payable by cleared funds on or before collection."

Delivery & risk:

"Risk in the Goods passes to the Buyer on delivery. Title passes to the Buyer upon full payment of the Purchase Price."

Indemnity:

"The Buyer indemnifies the Seller against any claim arising from the Buyer's use of the Goods after the date of delivery."

PPSR representation:

"The Seller confirms that a PPSR search dated 15/01/2025 produced no financing statements affecting the Goods (reference: 0000-0000)."

Include a witness block:

Witness: __________________ Name: __________________ Date: __________ ID type & number: __________

Common pitfalls and how to avoid them

Avoid these mistakes which commonly cause disputes:

Failing to run a PPSR search — buyer may end up with encumbered goods. Remedy: run and save the PPSR search result.
Vague descriptions — "old ute" is not enough. Remedy: include VIN/serial, registration and photos.
Not verifying identity — seller remains vulnerable to fraud. Remedy: copy government ID details into the bill.
Accepting non-cleared funds — bank cheques and transfers can bounce. Remedy: wait for cleared funds before handing over keys or title.
Forgetting to transfer registration — seller may remain liable for fines. Remedy: complete registry transfer promptly.
GST mistakes — businesses may fail to charge GST or issue proper invoices. Remedy: check the ATO guidance and document GST status in the bill.

FAQ

Is a bill of sale legally binding?

Yes, if it records agreement between competent parties and includes essential terms (price, description, signatures). A legally effective bill of sale serves as proof of the transaction and can be enforced in court.

Do I need a bill of sale to transfer registration?

No — registration transfer is a separate administrative step — but the bill of sale is useful evidence and often required by registries or insurers.

Do bills of sale need to be witnessed or notarised?

Not usually. Witnessing is recommended for high-value sales or where identity authenticity may be questioned.

Can a bill of sale be used for any kind of property?

Yes — it covers tangible personal property (vehicles, boats, equipment). Real property (land) requires different documentation.

What should I check on the PPSR?

Search by VIN/serial to confirm no financing statements. Save the receipt and include the reference in the bill. Go to https://www.ppsr.gov.au for more information.

How long should I keep sale records?

Keep records at least five years for tax and warranty reasons; businesses should retain according to ATO retention rules.

What if the buyer finds the goods were encumbered?

If the seller warranted no encumbrances and an interest existed, the buyer may have contractual remedies. Seek legal advice for recovery or compensation.

Key takeaways

A bill of sale is a simple but powerful document that protects both buyer and seller by recording the terms of the sale in writing. Complete it with accurate descriptions (including VINs or serial numbers), verify identity, run a PPSR check before sale, and document payment clearly. Remember to complete your state's registration transfer process separately, keep records for at least five years, and consult a lawyer for high-value or complex transactions.
