TL;DR – Antenuptial Contracts (ANCs) in South Africa
-
An antenuptial contract must be signed before marriage.
-
It determines whether the marriage is out of community of property, with or without accrual.

The contract must be executed before a notary and registered in the Deeds Office.

Poorly drafted ANCs are a leading cause of expensive divorce disputes.
Quick route: ANC, accrual or no accrual?
An antenuptial contract is not only a formality before the wedding. It chooses the property system for the marriage and can materially affect debt exposure, asset protection, estate planning and divorce outcomes.
- If you want fairness through shared growth, consider an ANC with accrual.
- If you want maximum separation, consider an ANC without accrual, but understand the consequences.
- If either party owns a business, property, trust interest, inheritance expectation or offshore asset, get tailored drafting before signing.

What is an antenuptial contract in South Africa?
An antenuptial contract is a legally binding agreement entered into by spouses before marriage. It regulates the matrimonial property system that will apply during the marriage and on dissolution.
In South Africa, the default marriage regime is in community of property. An antenuptial contract allows couples to marry out of community of property, either:
-
with the accrual system, or
-
without the accrual system.
Each option carries different legal and financial consequences.
Antenuptial contracts and the accrual system
The accrual system is the most common feature of modern antenuptial contracts. It allows spouses to share in the growth of each other’s estates during the marriage, while still protecting assets owned before marriage.
Key points courts look at:
-
Commencement values must be properly recorded.
-
Exclusions must be clear and legally enforceable.
-
Poor drafting can result in unintended sharing of assets.

Legal requirements for valid antenuptial contracts
For an antenuptial contract to be valid in South Africa:
-
It must be signed before marriage.
-
It must be executed before a registered notary public.
-
It must be registered in the Deeds Office, generally within three months after notarial execution in South Africa, unless a court grants an extension.
-
It must comply with the Matrimonial Property Act.
Failure to meet these requirements can render the contract unenforceable.
Antenuptial contracts in South Africa are governed by the Matrimonial Property Act 88 of 1984, which regulates marriage regimes and the accrual system.
Registration timeline and proof
Practically, the ANC route is: choose the marital-property regime, prepare the drafting instructions, sign before the notary, lodge for Deeds Registry registration, and keep proof of the registered contract. If the wedding is close, timing is not a formality. Section 87 of the Deeds Registries Act records a three-month registration period after execution in South Africa, subject to possible court extension.

Common mistakes with antenuptial contracts
We regularly see antenuptial contracts challenged or unravelled due to:
-
Incorrect or missing accrual commencement values
-
Vague asset exclusions
-
Templates used without legal tailoring
-
Late registration or defective notarisation
-
Failure to consider future business interests or inheritances
These issues usually only arise years later, during divorce or estate administration.
Antenuptial contract costs in South Africa
The cost of antenuptial contracts in South Africa depends on:
-
Whether accrual applies
-
The complexity of exclusions
-
Business or trust structures involved
-
Notarial and registration requirements
While basic ANCs are relatively affordable, poorly drafted contracts often lead to significant litigation costs later.
Cost clarity: ask whether the quoted fee includes consultation, tailored drafting, notarial execution, Deeds Registry registration, VAT, courier/admin disbursements and any urgency work. A cheap template is only cheap if it is valid, registered and fit for the couple’s actual risk profile.
