About this module
Educational tool, not legal advice. All law is South African.
This module teaches the South African law of specific contracts in plain language: the contracts people make every day, and the special rules the law attaches to each. It covers sale, lease, agency and representation, insurance, suretyship, and contracts to do work or render services. It builds on Module 3 (Law of Contract): the general rules on agreement, capacity, formalities, legality, breach and remedies still apply, and this module adds what is special to each type of contract.
Level: usually second or third year (LLB). Some universities teach it as "Specific Contracts", others split it into separate courses (for example a sale and lease course and a commercial contracts course).
Prior knowledge: Module 3 (Law of Contract) in full; Module 7 (Property Law) for ownership, delivery and registration; Module 6 (Constitutional Law) for the Bill of Rights cases on leases and insurance.
How to use it. Each chapter starts with a problem, gives the big picture, teaches the rules with leading cases, then ends with an "In short" summary, common mistakes, practice questions, flashcards and a short quiz. Cases are described with what happened, the issue, the principle and how it applies, so you can use them in problem questions.
Statutes you will meet: the Consumer Protection Act 68 of 2008 (CPA), the National Credit Act 34 of 2005, the Alienation of Land Act 68 of 1981, the Rental Housing Act 50 of 1999, the Prevention of Illegal Eviction from and Unlawful Occupation of Land Act 19 of 1998 (PIE), the Insurance Act 18 of 2017, the Long-term and Short-term Insurance Acts, and the General Law Amendment Act 50 of 1956 (s 6, suretyship).
Common cases and how they are checked
The module teaches from recent Supreme Court of Appeal and Constitutional Court judgments that are published in full on SAFLII, because those can be read and checked by anyone. Every case below was read on SAFLII or the SA Law Library on 22 October 2026, except where the status column says otherwise. Older Appellate Division cases that the textbooks rely on are named where needed, with their status stated.

Module blueprint
The module follows one question through every chapter: what type of contract is this, and what does the law add to it automatically? Chapters S1 to S5 teach sale, the contract every course starts with; S6 and S7 teach lease; S8 to S10 teach agency, insurance, suretyship and contracts for work.
| Chapter | Question it answers | Outcome |
|---|---|---|
| S1 Specific contracts in general | How do you tell one type of contract from another, and why does it matter? | SC1 |
| S2 Sale I: formation and ownership | When is there a sale, and when do risk and ownership pass? | SC2 |
| S3 Sale II: the seller's duties | What must the seller do, and what if a third party claims the thing? | SC3 |
| S4 Sale III: defects | What can the buyer do about a hidden defect, and what does voetstoots or the CPA change? | SC4 |
| S5 Sale IV: the buyer's duties and special sales | What must the buyer do, and what special rules govern land and credit sales? | SC5 |
| S6 Lease I: the contract and the duties | What makes a lease, and what does each side owe? | SC6 |
| S7 Lease II: third parties, termination and eviction | What happens when the property is sold, the lease ends or the tenant will not leave? | SC7 |
| S8 Agency and representation | When is a principal bound by what someone else agreed? | SC8 |
| S9 Insurance | What makes an insurance contract valid, and when may the insurer refuse to pay? | SC9 |
| S10 Suretyship and contracts for work | When is a surety liable, and what governs contracts to do work or render services? | SC10 |
| S11 Credit agreements | When does the National Credit Act apply, and what must a credit provider do before it can enforce? | SC11 |
Learning outcomes. By the end, you can:
- SC1: classify a contract by its essential terms and say which default rules (naturalia) follow.
- SC2: decide whether a valid sale exists and when risk, benefit and ownership pass.
- SC3: explain the seller's duty to deliver and the warranty against eviction, and advise a buyer who is evicted.
- SC4: tell a latent from a patent defect, choose between the aedilitian actions and the actio empti, test a voetstoots clause, and apply CPA ss 55 and 56.
- SC5: explain the buyer's duties and the seller's remedies, and apply the Alienation of Land Act to an instalment sale.
- SC6: identify a lease and state the duties of lessor and lessee, including remission of rent.
- SC7: apply huur gaat voor koop, terminate a lease lawfully, and explain how the Rental Housing Act and PIE affect eviction.
- SC8: decide whether an agent had actual or ostensible authority, and the effect of ratification.
- SC9: identify an insurance contract, test materiality of a misrepresentation or non-disclosure, and assess a time-bar clause.
- SC10: test a suretyship against s 6 of the General Law Amendment Act and explain the surety's defences; state the duties in contracts for work and services.
- SC11: decide whether the National Credit Act applies, identify reckless credit, apply the in duplum rule, and test whether a credit provider has met the s 129 and s 130 requirements before suing.
S1: Specific contracts in general
Problem. Thabo gives Lerato his old car in return for her laptop and R5 000. A week later the car's engine seizes because of a crack that was there before the deal. Lerato wants to know what she can claim. Before you can answer, you must know what contract they made: a sale, an exchange or something else? The answer decides which rules apply.
The big picture. Every contract follows the general rules from Module 3. Some contracts are so common that the law has developed a fixed package of rules for them: sale, lease, agency, insurance, suretyship and others. Once you know which type you are dealing with, those rules apply automatically unless the parties agreed otherwise.
S1.1 Three kinds of terms
- Essentialia are the terms that define the type of contract. A sale needs agreement on the thing sold (the merx) and the price (the pretium). Without them there is no sale, though there may be another contract.
- Naturalia are the terms the law adds automatically to that type of contract. In a sale, the seller warrants against eviction and against latent defects. The parties do not have to mention them; they apply unless excluded.
- Incidentalia are the extra terms the parties choose to add, such as a voetstoots clause, a delivery date or a penalty clause.
In short: essentialia tell you what the contract is; naturalia tell you what the law adds; incidentalia are what the parties add or change.
S1.2 Why classification matters
The type of contract decides the naturalia, any formalities, and which statutes apply. For example, a sale of land must be in writing and signed (Alienation of Land Act 68 of 1981, s 2(1)); a suretyship must be in writing and signed by the surety (General Law Amendment Act 50 of 1956, s 6); a sale or lease of residential property brings in the Rental Housing Act or the Consumer Protection Act.
Courts look at the substance, not the label. A contract called a "lease" in which the user pays the full value and becomes owner at the end may in substance be an instalment sale. Classify by the essential terms the parties actually agreed on.
| Contract | Essential terms | Key naturalia |
|---|---|---|
| Sale | A thing, a price in money, and the intention to buy and sell | Warranties against eviction and latent defects; risk passes on a perfecta sale |
| Exchange (barter) | Two things swapped, no money price | Similar warranties, by analogy with sale |
| Lease | Temporary use and enjoyment of a thing, for rent | Lessor must deliver and maintain; lessee must pay rent and return the thing |
| Agency (mandate) | One person acts for another, on instructions | Duty to follow instructions, account, act in good faith |
| Insurance | Payment of a premium for cover against an uncertain event | Good faith and a duty to disclose material facts (South African law does not treat "utmost good faith" as a separate standard) |
| Suretyship | A promise to pay if the principal debtor does not | Accessory to the main debt; benefits of excussion and division (unless renounced) |
S1.3 Mixed contracts
Some deals do not fit one type. In the problem, Thabo gets a laptop and money for his car. The usual approach is to ask which performance is dominant. If the money is the main counter-performance, treat it as a sale; if the laptop is, treat it as an exchange. Either way the warranty against latent defects applies, so Lerato will have a claim if the crack was a latent defect (see S4).
S1.4 The Consumer Protection Act in outline
The Consumer Protection Act 68 of 2008 (CPA) overlays the common law for many sales, leases and service contracts. It applies to transactions in the ordinary course of a supplier's business with a consumer, subject to exclusions such as transactions with the State and with larger juristic persons (above the threshold the Minister sets). It adds statutory rights the parties cannot contract out of, for example:
- the right to safe, good-quality goods (s 55) and the implied warranty of quality with a six-month return right (s 56);
- limits on unfair, unreasonable or unjust terms (ss 48 to 52);
- rules for fixed-term agreements and cancellation (s 14).
The common law still applies alongside the CPA: s 56(4) says its warranty is in addition to the common-law warranties. So always check both. A private sale between two individuals (Thabo and Lerato) is not "in the ordinary course of business", so the CPA does not apply and the common law governs.
In short. Identify the contract by its essentialia. The type decides the naturalia, the formalities and the statutes. Look at substance, not labels. Check whether the CPA applies on top of the common law.
Common mistakes
- Treating a voetstoots clause as a natural term. It is an incidentale: it applies only if agreed.
- Applying the CPA to a private sale between individuals.
- Classifying by the name on the document instead of the essential terms.
S1 practice
- Nomsa agrees to let Pieter use her bakkie for a month for R3 000. What contract is this, and what are its essentialia? Answer: a lease of a movable; temporary use and enjoyment of the bakkie, and rent of R3 000.
- A dealer sells a fridge "voetstoots" to a consumer in the ordinary course of business. Does the CPA's implied warranty of quality still apply? Answer: yes; s 56 applies in addition to the common law, and the CPA limits contracting out of its protections. See S4.
- Why does it matter whether a deal is a sale of land? Answer: s 2(1) of the Alienation of Land Act requires writing signed by the parties; without it the sale is void.
