The rule: a sale does not break the lease
The Roman-Dutch maxim huur gaat voor koop — “hire goes before sale” — is one of the most practically important rules in South African property law. Under Roman law a lessee held no real right in the leased property; he had a personal right against the lessor only, and a buyer of the property could evict him. The maxim reversed this. Derived from local custom and legislation in parts of the Netherlands, it passed into Roman-Dutch law and, from there, into South African law.
The essence of the rule is this: where the leased property is sold, the sale does not terminate the lease. The purchaser is bound to recognise the lessee’s right of occupation and may not eject the lessee before the term of the lease expires, provided the lessee continues to pay the rent and otherwise to observe his obligations under the lease.
The practical consequence is significant: a lessee in occupation when the property changes hands cannot walk away simply because the lessor has changed. The lease continues on its existing terms with the new owner stepping in as lessor.
The buyer steps into the lessor’s shoes
The mechanism of huur gaat voor koop is not a cession of rights or an assignment of obligations in the contractual sense. It is an operation of law. No agreement between the original lessor and the buyer is needed, and the lessee’s consent is not required. The substitution happens automatically on transfer.
The result is clean and straightforward: from the moment of transfer the buyer is both entitled to claim the rent from the lessee and obliged to perform the lessor’s obligations under the lease. The original lessor is discharged entirely. There is no period during which the lessee owes rent to the seller and the buyer simultaneously.
What carries — and what does not
The new owner acquires the rights and obligations that constitute the lease relationship properly so called: the right to receive rent, the obligation to provide undisturbed occupation, the duration of the lease, and the lessee’s right of renewal if the lease contains one.
By contrast, an option to purchase the leased property is treated differently. The option is a personal right between the original lessor and the lessee; it relates not to occupation but to a competition over ownership (dominium). As the Appellate Division observed in Mignoel, the buyer acquires all the rights of the original lessor except collateral rights unconnected with the lease. An option to purchase is the paradigm case of such a collateral right: it is a pactum de contrahendo by which the lessor undertakes to keep open an offer to sell, and it does not relate to the lessee’s right of occupation as lessee. The full treatment of options to purchase and other collateral rights is covered in its own guide.
In short: carries to the new owner — occupation, rent, duration, rights of renewal, and all other obligations arising from the landlord–tenant relationship. Does not carry — options to purchase and other collateral rights that compete for dominium rather than protecting the right of occupation.
It is mutual: the lessee is also bound
The rule operates bilaterally. Just as the buyer is bound to accept the lessee and may not eject him before the term expires, the lessee is bound to the new owner. The lessee owes rent to the buyer, not to the original lessor, and must perform all his obligations under the lease to the new owner. The lessee cannot refuse to deal with the new owner simply because the lessor’s identity has changed.
This mutuality is practically important. Where the buyer takes transfer and the lessee refuses to pay rent on the basis that he owes it only to the original lessor, he is in breach of the lease. Equally, where the buyer refuses to perform the lessor’s obligations — for example, refusing to carry out repairs the original lease required — the lessee has a claim against the buyer, not merely a personal claim for damages against the original lessor.
Registration and the 10-year limit
The common-law rule of huur gaat voor koop protects a lessee in possession by preventing the new owner from ejecting him. But for long leases — leases of land entered into for ten years or more, for the life of the lessee, or renewable indefinitely at the lessee’s will — statute imposes an additional constraint.
Section 1(2) of the Formalities in Respect of Leases of Land Act 18 of 1969 provides that an unregistered long lease is not valid against a creditor or successor under onerous title of the lessor for a period longer than ten years after the lease was entered into — unless that creditor or successor knew of the lease at the relevant time. This statutory ten-year limitation overlays and qualifies the common-law rule:
- During the first ten years from when the lease was concluded: an unregistered long lease is fully protected by huur gaat voor koop. A buyer who purchases the property during this period is bound to honour the lease for so much of the remaining term as falls within the ten-year window, and possibly the full remaining term if the lessee was in possession and the buyer had notice.
- After ten years from conclusion: a buyer who acquires the property for value, in good faith, and without actual knowledge of the lease takes free of it. The common-law protection of huur gaat voor koop no longer overrides the statutory rule. The lessee is exposed and can be evicted.
- With registration: once a long lease is notarially executed and registered against the title deed of the leased land, it becomes a limited real right and binds every successor in title and every creditor of the lessor for the full term, regardless of whether they knew of the lease or not. Registration replaces reliance on huur gaat voor koop and the knowledge doctrine with full statutory protection.
The knowledge doctrine — how actual knowledge of an unregistered long lease can still bind a buyer or creditor beyond the ten-year period, and what inquiries a buyer must make to establish that knowledge — is explored in the guide to the 10-year rule and the knowledge doctrine.
The registration process — notarial execution, lodgement at the Deeds Registry, and endorsement on the title deed — is covered in the guide to registering a notarial lease.
