Loan agreement in South Africa: Template, Key Clauses and Local Law (2026)

What a loan agreement is in South Africa A loan agreement records money lent and how it is repaid. In South Africa the decisive question is whether the loan is a credit agreement under the National Credit Act 34 of 2005 (NCA). If it is, a long list of consumer protections applies: the lender may need to register as a credit provider, interest is capped by regulation, and a statutory version of the in duplum rule limits how much a consumer in default can be charged. If the loan falls outside the NCA, it is governed by the common law of contract and the common law in duplum rule. Many ordinary loans are covered by the NCA, including loans by a business to a consumer and many loans at interest. Some are excluded, for example certain loans between companies above a threshold, or loans where the parties are at arm's length in ways the Act defines. Because the consequences of getting this wrong are serious, including an unenforceable agreement, this is the first thing to check. This page is general information, not legal advice. The NCA is detailed and the prescribed rates change, so confirm the current position and rates with a South African attorney or the National Credit Regulator before you lend at interest. ## What South African law requires - The NCA question. Decide whether the loan is a credit agreement under the NCA. If it is, the Act's protections apply and the lender may need to be a registered credit provider.

• Registration. A credit provider that must register but does not can find its agreement unenforceable, so check the registration duty before lending.
• Interest caps (section 105). For credit agreements, maximum interest is set by regulation as a repo linked formula for each sub sector, fixed at the rate prevailing when the credit is granted. Reported examples include a cap of the repo rate plus a margin for unsecured credit and a lower cap for mortgages. Confirm the current figures against the National Credit Regulations.
• Statutory in duplum (section 103(5)). Once a consumer is in default, the total of interest, fees and charges that accrue cannot exceed the unpaid balance of the principal at the time of default. This covers more than interest, including initiation fees, service fees, default admin charges and collection costs.
• Common law in duplum. Outside the NCA, the common law rule stops arrear interest once it equals the outstanding principal. ## The clauses that differ in South Africa - NCA status. State whether the loan is a credit agreement under the NCA, and if so, comply with its disclosure and cost rules.
• Interest. For an NCA loan, keep interest within the prescribed cap. For a non NCA loan, set a fair rate, mindful of the common law in duplum rule.
• Costs and fees. Keep fees within the NCA limits where it applies, because the in duplum rule folds them into the cap on default.
• Security. Describe any security, such as a surety or a mortgage bond, and how it is enforced. ## A South Africa loan agreement template you can adapt ``` LOAN AGREEMENT Date: [date] Lender: [full name / company, registration number, address] Borrower: [full name / company, ID or registration number, address] 1. LOAN The Lender lends the Borrower R[amount in figures and words] (the "Loan"). The parties record that this [is / is not] a credit agreement under the National Credit Act 34 of 2005. [If it is, the Lender confirms it is a registered credit provider where required.] 2. PURPOSE The Loan is for [purpose]. 3. INTEREST [Option A: The Loan is interest free.] [Option B: The Loan carries interest at [rate]% per year on the outstanding principal, within any applicable NCA cap, from [date] until repaid.] 4. REPAYMENT The Borrower repays by [lump sum on [date]] / [[number] monthly instalments of R[amount] from [date]] to [account details]. 5. EARLY REPAYMENT The Borrower may repay early without penalty, with interest reduced accordingly. 6. COSTS AND FEES Any fees are [list], and where the NCA applies they stay within its limits. On default, total interest, fees and charges will not exceed the unpaid principal as required by the in duplum rule. 7.

DEFAULT If the Borrower misses a payment by [number] days or becomes insolvent, the whole outstanding balance becomes due, subject to any NCA notice requirements. 9. GOVERNING LAW AND DISPUTES Governed by the law of the Republic of South Africa. Disputes go to [the courts] / [arbitration]. SIGNED Lender ____________ Borrower ____________ Witnesses ____________ ____________

- Charging interest above the prescribed NCA cap for the relevant sub sector.
- Ignoring the in duplum rule, which limits total charges on default to the unpaid principal.
- Loading fees that push the cost beyond what the NCA allows.
- A vague repayment term. Use figures and dates. ## Keeping a loan and its paperwork in step A loan does not end at signing. Instalments fall due, security sits in the background, a borrower in default triggers NCA notices and the in duplum cap, and a schedule change has to be tracked. The work that outlasts the signing is keeping the current terms, the security, the repayment record and the key dates together, and knowing which clause and which notice matter the moment a payment is missed. That is the same problem a company has across its contracts, and a regulated loan makes it concrete. Drafting from a clear template, spotting a term that will not hold under local law, editing a clause in plain language and holding every version with its date can live in one AI workspace tuned to how your company contracts. [Adira](https://adiralaw.com) is built around that single workspace idea, deepest today on Indian corporate law, with South Africa coverage on its roadmap rather than fully built, so treat its South African depth as developing. For this loan, the template and the local law points above stand on their own; the idea worth borrowing is that a contract and the records around it are easier to trust when they live in one place.
