Promissory Note

A written, unconditional promise by one person (maker) to pay a specified sum of money to another person (payee) at a specified time or on demand.

Legal Definition

A promissory note is a negotiable instrument — a written promise to pay a fixed sum. It is governed by the Bills of Exchange Act 34 of 1964. Promissory notes are commonly used in loan agreements and commercial transactions. They can be endorsed (transferred) to a third party who then has the right to collect. Dishonour of a promissory note entitles the holder to immediate legal action without proving the underlying debt.

📖 Constitutional / Statutory Basis: Section 34 (access to courts)

Practical Example

A borrower signs a promissory note promising to repay R50,000 to the lender on 31 March 2026. If the borrower fails to pay, the lender can sue immediately on the promissory note without proving the loan agreement.

Frequently Asked Questions

Is a signed IOU the same as a promissory note in South Africa?

An IOU is informal. A promissory note under the Bills of Exchange Act must contain specific elements: an unconditional promise to pay, a specified sum, a specified payee, and a date or demand requirement. A properly drawn promissory note has stronger legal enforcement rights.

Can a promissory note be used as a surety in South Africa?

Yes — a promissory note signed by a third party (maker) can serve as surety for another's debt. The holder can enforce the note against the maker without first pursuing the primary debtor.
