Promissory Note (Australia)

A Promissory Note in Australia is a legally binding written instrument.

Section 89 of the Bills of Exchange Act 1909 defines a promissory note as “an unconditional promise in writing made by one person to another, signed by the Maker, engaging to pay, on demand or at a fixed or determinable future time, a sum certain in money, to, or to the order of, a specified person or to bearer.” For an instrument to qualify as a promissory note under the Act, the promise must be truly unconditional — any condition attached to the obligation to pay will disqualify the instrument as a valid negotiable instrument, though it may still be enforceable as an ordinary contract.

One of the most commercially significant features of a promissory note is its negotiability. A promissory note payable to a named person “or order” can be transferred from the Payee to a third party by endorsement and delivery. The transferee becomes the holder of the note and, if the transferee satisfies the requirements for a “holder in due course” under the Act, they take the note free from most personal defences the Maker might have raised against the original Payee. This makes promissory notes a useful instrument in trade finance, inter-company lending, and factoring arrangements.

A promissory note differs from a cheque in that it is not drawn on a bank and is not payable on demand by default — it may be made payable on demand or at a specified future date. It differs from a bill of exchange in that it involves only two parties (Maker and Payee) rather than three (drawer, drawee, and payee).

For consumer credit purposes, a promissory note alone is insufficient to comply with the disclosure requirements of the National Consumer Credit Protection Act 2009 (Cth) and the National Credit Code. Consumer lenders must provide additional mandatory disclosures and must hold an Australian Credit Licence.

The legal framework governing the Promissory Note (Australia) in Australia draws on several key statutes and regulatory bodies. Under the Corporations Act 2001 (Cth) and the Australian Securities and Investments Commission Act 1989, ASIC regulates financial products and services. The National Consumer Credit Protection Act 2009 (Cth) governs consumer lending. The Australian Taxation Office (ATO) applies stamp duty through state revenue offices. The Australian Financial Complaints Authority (AFCA) resolves consumer financial disputes. The Reserve Bank of Australia (RBA) sets monetary policy affecting interest rate obligations in financial agreements. Parties executing a Promissory Note (Australia) in Australia should confirm the document reflects current law, including any amendments enacted since the original drafting date. The National Consumer Credit Protection Act 2009 (Cth) sets the foundational requirements.

A Promissory Note is used in Australia when a simple, formal written acknowledgment of a debt and a promise to pay is needed — particularly when the parties want an instrument that can potentially be transferred to a third party, or when the simplicity and clarity of a negotiable instrument is preferable to a full loan agreement.

A Promissory Note is appropriate in the following circumstances:

Business-to-business lending between related entities, where a company lends funds to an associated entity and wants a clear written record of the debt. A promissory note evidencing the loan may also satisfy the documentary requirements under Division 7A of the Income Tax Assessment Act 1936 (Cth) for loans between private companies and their shareholders or associates, though specific Division 7A requirements must be carefully checked with a tax adviser.

Informal personal loans between individuals, where one person lends money to another and wants a simple written record of the amount and repayment terms without the complexity of a full loan agreement.

Commercial transactions where goods or services are purchased on credit and the buyer issues a promissory note as evidence of the obligation to pay at a future date. In this context, the seller may discount or transfer the promissory note to a financier in exchange for immediate funds.

Inter-company transactions within a corporate group, where a holding company or subsidiary advances funds to another group entity. A promissory note simplifies the documentation of intra-group loans.

Supplementary security, where a promissory note is issued alongside a more detailed loan agreement or security agreement to provide an additional, easily enforceable instrument evidencing the debt.

A Promissory Note is not appropriate as a standalone document for consumer credit regulated by the NCCP Act 2009. For such loans, a full credit contract complying with the National Credit Code is required.

A valid Australian Promissory Note under the Bills of Exchange Act 1909 (Cth) must contain certain essential elements.

Australian courts have addressed the enforceability and limitations of promissory notes in ways that directly affect how these instruments must be drafted. In Radan and Gooley v MBF Investments Pty Ltd [2008] VSCA 11, the Victorian Court of Appeal examined a disputed promissory note and confirmed that the requirement for an 'unconditional promise to pay' under the Bills of Exchange Act 1909 (Cth) is strictly construed — any qualification or condition precedent attached to the obligation to pay disqualifies the instrument as a valid negotiable promissory note, even if it remains enforceable as an ordinary contract. The practical lesson is that promissory notes must contain a clean, unqualified promise to pay a fixed sum, without reference to business performance, the occurrence of any external event, or the satisfaction of any other condition. Under section 89 of the Bills of Exchange Act 1909 (Cth), the promise must be for 'a sum certain in money' — courts have refused to enforce notes where the amount payable was uncertain because it was tied to a variable (such as an unspecified interest rate or a contingent payment mechanism). In Equuscorp Pty Ltd v Haxton (2012) 246 CLR 498, the High Court examined the enforceability of loan instruments in the context of void or illegal underlying transactions, confirming that a promissory note is not an independent instrument that will be enforced regardless of the underlying purpose of the loan if that purpose is unlawful or the contract from which it arises is tainted by illegality. Practitioners must confirm that the underlying transaction is lawful before relying on the promissory note as an enforcement tool. Additionally, where the Maker is a company, section 127 of the Corporations Act 2001 (Cth) prescribes how the company must execute the instrument to bind itself — execution by a single director without proper authority does not bind the company.

The unconditional promise to pay is the cornerstone of the instrument. The promise must be absolute and unqualified — the Maker must commit to pay regardless of any external event or condition. Phrases such as “I promise to pay provided that...” or “I will pay when my business has sufficient funds” negate the unconditional nature of the promise and disqualify the instrument as a negotiable promissory note under the Act.

The sum certain in money must be stated clearly and without ambiguity. Best practice is to state the amount both in figures and in words — for example, AUD $25,000 (Twenty-Five Thousand Dollars) — to eliminate any possibility of alteration or dispute.

The name of the Maker (the person making the promise) and the Payee (the person to whom payment is promised) must be clearly stated. For an individual Maker, the full legal name and address are required. For a corporate Maker, the full company name, ACN or ABN, and registered address should be included. If the Maker is a company, the note should be executed by an authorised signatory in accordance with the Corporations Act 2001 (Cth).

The maturity date determines when payment is due. A promissory note may be payable on demand (meaning payment can be demanded at any time after the note is issued), on a fixed future date, or at a determinable future time (such as a specified number of days after sight). For a demand note, the Payee can require payment at any time by presenting the note to the Maker.

Negotiability language — specifically, the words “or order” after the Payee’s name — makes the note transferable by endorsement. If the note is payable simply to the named Payee without “or order” language, it is not automatically negotiable under the Act.

Interest provisions should specify the annual rate, the calculation basis (usually daily on the outstanding balance), and the start date. Default interest provisions incentivise timely payment and compensate the Payee for the cost of enforcement.

The waiver of dishonour notice is a standard provision in commercial promissory notes. Under the Act, failure to give formal notice of dishonour may discharge certain parties from liability. By including an express waiver, the Maker agrees to remain liable regardless of whether formal notice procedures are followed.

The governing law clause specifies which Australian state or territory’s law governs the note. While the Bills of Exchange Act 1909 is a Commonwealth Act that applies nationally, state law may be relevant for limitation periods, court procedures, and stamp duty.

Australian Promissory Notes are frequently drafted with errors that either disqualify the instrument as a valid negotiable instrument under the Bills of Exchange Act 1909 (Cth) or expose the Payee to enforcement difficulties. The following mistakes are the most common.

1. Including a conditional promise. The Bills of Exchange Act 1909 (Cth) section 89 requires an unconditional promise to pay. Any condition attached to the obligation to pay, such as payment subject to business performance or completion of a separate transaction, disqualifies the instrument as a promissory note. The Victorian Court of Appeal in Radan and Gooley v MBF Investments Pty Ltd [2008] VSCA 11 confirmed this strict requirement. The instrument may still be enforceable as an ordinary contract but loses the advantage of being a negotiable instrument.

2. Failing to state the sum certain in money. A promissory note for a reasonable sum for services rendered or the balance owing under the supply agreement does not qualify as a valid promissory note. The amount must be fixed and ascertainable from the face of the instrument itself, typically stated both in figures and in words to prevent alteration.

3. Using a promissory note for consumer credit without NCCP Act disclosures. A promissory note alone does not satisfy the disclosure requirements of the National Consumer Credit Protection Act 2009 (Cth) and the National Credit Code. Lenders who use a promissory note as a standalone instrument for consumer lending risk criminal penalties and the unenforceability of the loan.

4. Corporate Maker executing without proper authority. A promissory note executed on behalf of a company must comply with section 127 of the Corporations Act 2001 (Cth), requiring execution by two directors or a director and company secretary. A note signed by a single director without board resolution conferring authority does not bind the company.

5. No interest rate specified or rate exceeds legal limits. A promissory note that does not specify an interest rate will bear no interest, meaning the Payee receives back only the face amount. Where interest is intended, the rate must be stated clearly, and default interest must also be specified.

6. Demand notes with no demand procedure. A promissory note payable on demand is immediately due and payable from the date of issue. If the Payee never makes a formal demand, limitation periods can complicate enforcement. A well-drafted demand note should specify the form of demand, the notice period between demand and required payment, and how demand is served.

7. Failing to include a waiver of notice of dishonour. Under the Bills of Exchange Act 1909 (Cth), failure to give formal notice of dishonour may discharge certain parties from liability. Including an express waiver eliminates this procedural requirement and simplifies enforcement, which is a standard feature of commercial promissory notes in Australia.

8. No endorsement procedure for intended negotiability. A promissory note intended to be transferred to a third party must contain the words or order after the Payee's name to be negotiable by endorsement under the Bills of Exchange Act 1909 (Cth). A note payable simply to a named person without or order language cannot be transferred to a holder in due course.

9. Relying on the promissory note as the sole record of a complex loan. A promissory note is a simple instrument designed to evidence a debt and promise to pay. Where the loan involves complex terms such as security, multiple tranches, or events of default, a full loan agreement is required alongside or instead of the promissory note.

10. Illegality or improper purpose invalidating the underlying obligation. As confirmed in Equuscorp Pty Ltd v Haxton (2012) 246 CLR 498, a promissory note connected to an illegal or void underlying transaction may not be enforceable even if the note itself is formally valid. A lender who uses a promissory note in connection with an unlicensed consumer credit arrangement risks both the unenforceability of the note and regulatory consequences under the NCCP Act 2009.
