Guarantor Promissory Note Template for Australia

A Guarantor Promissory Note is a powerful legal instrument that provides creditors with enhanced security by combining a traditional promissory note with a third-party guarantee. This document creates a legally binding obligation where both the primary debtor and guarantor become liable for the debt repayment, giving you stronger protection than a standard promissory note alone.

When do you need this document?

You'll need a Guarantor Promissory Note when lending money or extending credit where the primary debtor's creditworthiness alone is insufficient. This commonly occurs in business financing scenarios where a startup seeks funding but lacks established credit history, requiring a director or investor to guarantee the loan. Property transactions frequently use these documents when buyers need additional financing beyond their mortgage capacity. Family lending situations also benefit from guarantor arrangements, particularly when parents guarantee loans for adult children's business ventures or property purchases. Commercial suppliers often require guarantor promissory notes when extending significant trade credit to new or financially unstable customers.

Key legal considerations

The guarantor's liability under this document is typically joint and several, meaning you can pursue either party for the full debt amount. However, the guarantor must receive independent legal advice before signing, as required under Australian consumer protection laws. The document must clearly define the principal sum, interest rate, payment terms, and events of default to ensure enforceability. You should include provisions addressing what happens if the primary debtor's circumstances change, such as bankruptcy or restructuring. The guarantee should specify whether it covers just the principal amount or extends to interest, fees, and enforcement costs. Consider including clauses that allow the guarantor to step into the debtor's position if they make payments, preserving their rights of subrogation and contribution.

Legal requirements in Australia

Under the Bills of Exchange Act 1909 (Cth), your promissory note must contain specific elements including an unconditional promise to pay, a fixed sum, and be payable on demand or at a determinable time. The National Consumer Credit Protection Act 2009 (Cth) applies additional requirements if this involves consumer credit, including mandatory disclosure of terms and the guarantor's right to independent advice. State-based legislation like the Contracts Review Act 1980 (NSW) allows courts to review potentially unjust guarantee terms, so ensure your document reflects fair and reasonable obligations. Banking regulations may also apply if you're a licensed financial institution. The document should comply with Australian Consumer Law provisions regarding unfair contract terms, particularly when dealing with individual guarantors rather than sophisticated commercial parties. Proper execution requires witnesses and may need stamping in certain states depending on the debt amount and jurisdiction.
