Estoppel

A legal principle that prevents a party from asserting a position that contradicts what they previously said or did, where another party relied on the earlier representation to their detriment.

Legal Definition

Estoppel arises when a person makes a representation (by words or conduct) that another person reasonably relies on, and it would be unjust to allow the first person to resile from the representation. South African courts recognise estoppel as a common law defence that can prevent enforcement of strict legal rights.

📖 Constitutional / Statutory Basis: Section 34 (fair hearing / legitimate expectation)

Practical Example

A landlord who accepts late rent for 6 months may be estopped from immediately cancelling the lease when the tenant pays late again, without first giving notice that they will enforce the payment date strictly.

Frequently Asked Questions

Can estoppel create new rights in South African law?
Estoppel can prevent a party from enforcing a right, but South African courts have held that estoppel cannot create new rights that do not otherwise exist — it is a shield, not a sword.
What is the difference between estoppel and waiver?
Waiver is the voluntary abandonment of a right. Estoppel does not require intention to abandon a right — it requires only that the representation was made, relied upon, and that resiling would be unjust.
