What is the Meaning of an Antenuptial Contract in South Africa?

An antenuptial contract (ANC) in South Africa is a notarial agreement signed by two people before their marriage that sets out the matrimonial property regime they have chosen — either out of community of property (with or without the accrual system) or in community of property — and contracts out of the default in-community-of-property regime that would otherwise apply on marriage under the Matrimonial Property Act 88 of 1984. The contract must be signed by both parties in the presence of a notary public and two competent witnesses before the marriage takes place, and it must be lodged for registration in a Deeds Registry within the prescribed period after the marriage so that it binds third parties such as creditors. If a couple wishes to change the property regime after they are already married, they cannot sign an ANC — they would need a postnuptial contract, which requires a court application under section 88 of the Matrimonial Property Act and is not granted automatically.

What an Antenuptial Contract Is in South African Law

An antenuptial contract is a pre-marital contract that determines the matrimonial property regime the couple has chosen for their marriage. It is governed primarily by the Matrimonial Property Act 88 of 1984, whose sections 85 and 86 set out the formalities for ANCs executed before and after 1 November 1984 respectively, together with the Deeds Registries Act 47 of 1937, which governs the registration step.

The contract must be signed before the marriage ceremony. If it is signed afterwards, it is not an antenuptial contract and has no automatic legal effect — the parties would then need to approach the High Court for a postnuptial regime change under section 88 of the Matrimonial Property Act.

Couples who marry without an ANC are married in community of property by default. An ANC is the mechanism that allows a couple to contract out of that default and choose a regime that better fits their circumstances. The three regimes available, and how each one works, are set out below.

What an ANC Must Contain to Be Valid

For an antenuptial contract to be valid it must be drafted and executed with a number of formalities. The requirements are settled under the Act and applied strictly by notaries and the Deeds Registry:

1. The full identifying details of both prospective spouses.
2. A clear statement of the chosen matrimonial property regime — out of community of property without accrual, out of community of property with accrual, or in community of property.
3. Signature by both parties in the presence of a notary public.
4. Two competent witnesses, each over the age of 14 and able to sign and, where required, read the document.
5. The notarial attestation, signed and sealed by the notary.

A contract that omits any of these steps is at risk of being set aside in later dealings with third parties such as creditors, even if both spouses intended to bind themselves to the chosen regime.

The Three Property Regimes Couples Can Choose

Regime	What it means	Estate position on divorce or death
In community of property (default)	All assets and liabilities of both spouses are pooled into one joint estate.	The joint estate is divided equally between the spouses (or their estates) on dissolution.
Out of community of property WITHOUT the accrual system	Each spouse retains a separate estate throughout the marriage.	Each spouse keeps their own estate — no sharing of assets or growth.
Out of community of property WITH the accrual system	Each spouse retains a separate estate, but the growth (accrual) in each estate during the marriage is shared on dissolution.	The spouse whose estate grew less is entitled to a 50% share of the difference between the two accruals.

The accrual system is often described as a “middle path”: it preserves each spouse’s independence during the marriage while still requiring a fair sharing of what was built up together while married. Couples who want that sharing but also want to ring-fence their pre-marital assets generally opt for out of community of property with accrual.

Why Couples Sign an ANC

Couples sign an antenuptial contract for a range of reasons that go beyond simply keeping finances separate. The most common motivations are:

• To keep premarital assets (property, investments, business interests, expected inheritances) separate from the marital estate.
• To provide certainty for blended families, second marriages, or existing children from a prior relationship.
• To manage existing debt exposure from one spouse so it does not encumber the joint estate.
• To make estate planning simpler and more predictable, particularly where one spouse has significantly more assets than the other at the date of marriage.
• To choose the accrual system rather than full separation, balancing independence with a fair sharing of growth built up during the marriage.

Burger Huyser Attorneys’ family law department handles antenuptial contracts as part of its regular work and is regularly asked to draft ANCs for couples across Gauteng — Sandton, Centurion, Pretoria (Menlyn), Bedfordview, Roodepoort, Alberton and Midrand — through the firm’s head office in Linden, Randburg.

What an ANC Does and Does Not Guarantee

An antenuptial contract is a powerful planning tool, but it is not absolute protection against every future claim. The settled position is as follows:

• An ANC binds the spouses to the chosen regime — it cannot be unilaterally varied after marriage without a court order.
• The accrual system is a sharing mechanism on dissolution of the marriage by death or divorce — it does not give the other spouse a present interest in the growing estate during the marriage.
• A court retains discretion under section 8 of the Divorce Act 70 of 1979 to make a redistribution order if it would be just, even where an ANC was signed — the contract is not absolute protection against redistribution claims on divorce.
• An ANC does not override the need for a valid will if the spouses want to direct who inherits their separate estates on death.

What this means in practice is that an ANC substantially reduces the risk of an unintended redistribution claim, but it does not extinguish it entirely, particularly where the accrual system was excluded or where one spouse contributed to the other’s estate in ways the contract did not anticipate.

Antenuptial Contract vs Postnuptial Contract

The two instruments look similar on paper but are governed by entirely different rules, and the distinction matters at the point of signing:

Feature	Antenuptial contract (ANC)	Postnuptial contract
When signed	Before the marriage.	After the marriage.
Takes effect	Automatically on the date of marriage, once registered in a Deeds Registry.	Only once a court grants an order under section 88 of the Matrimonial Property Act 88 of 1984 changing the existing regime.
Court involvement	Not required (notary and Deeds Registry only).	Required — the application is not automatic.
Court approach	Standard.	Cautious — sound reasons needed; a change of mind is generally not enough.

Most couples who want a customised property regime choose to do it as an ANC before the wedding, both because the postnuptial route is uncertain and because it can affect the validity of the existing marital regime in the meantime.

How an ANC Is Drafted and Registered in Practice

The practical steps for getting an ANC in place run as follows:

1. A notary public (in many cases working alongside an attorney) drafts the contract.
2. Both parties and the two witnesses attend the notary’s office before the marriage date.
3. The notary signs and seals the document and lodges it for registration in the Deeds Registry covering the area where the marriage is to be recorded.
4. Registration must take place within the period prescribed by the Deeds Registries Act 47 of 1937. The contract is binding between the spouses from the date of marriage, but registration is what makes it enforceable against third parties (such as creditors of one spouse).

The marriage officer is not involved in drafting or registering the ANC — the ANC and the marriage registration are separate processes.

Cost and Timeline Considerations

Fees for a straightforward ANC — out of community of property, with or without accrual, with no unusual assets — are commonly advertised by notaries in the lower-thousand-rand range as an all-inclusive package. More complex files cost more and take longer to draft:

• Multiple properties, foreign-domiciled parties, blended-family clauses, and accrual-exclusion provisions all add to the drafting time.
• Couples typically allow a few weeks between the first consultation and the notary attestation; the Deeds Registry filing happens after the marriage.
• Engaging an attorney alongside the notary is advisable where the regime choice has estate-planning, tax or family-business implications that the notary alone will not advise on.

Because fees are quoted per file after review, it is worth asking the notary or attorney for a written quote once the scope of the contract is known.

Frequently Asked Questions

What does “antenuptial” actually mean?

“Antenuptial” literally means “before marriage” (from the Latin ante, meaning before, and nuptialis, meaning of marriage). An antenuptial contract is therefore a contract concluded before the marriage that sets out the matrimonial property regime the couple is choosing. Anything concluded after the marriage is a postnuptial contract and is treated differently under the Matrimonial Property Act 88 of 1984.

Is an antenuptial contract legally required in South Africa?

No, an ANC is optional. Couples who do not sign one are married in community of property by default under South African law, meaning all assets and liabilities are pooled into one joint estate. Many couples sign an ANC precisely so that they can contract out of that default and keep some or all of their estates separate.

Can you sign an antenuptial contract after the marriage?

Not as an ANC. A contract signed after the marriage is a postnuptial contract and requires a High Court application under section 88 of the Matrimonial Property Act 88 of 1984 to change the existing matrimonial property regime. Postnuptial applications are granted only when the court is satisfied that there are sound reasons to alter the regime, and the application is not automatic.

Does an antenuptial contract need to be registered?

Yes. The contract must be signed before the marriage and lodged for registration in a Deeds Registry within the period prescribed under the Deeds Registries Act 47 of 1937. Registration is what makes the contract enforceable against third parties such as creditors. Between the spouses, the contract takes effect on the date of marriage, but an unregistered ANC can be set aside in dealings with third parties.

What is the difference between an ANC with and without the accrual system?

An ANC without accrual creates complete separation of estates: each spouse keeps their own assets and liabilities, and there is no sharing on divorce or death. An ANC with accrual keeps separate estates during the marriage but requires the spouses to share the growth (the accrual) of each estate on dissolution of the marriage by death or divorce, with the spouse whose estate grew less entitled to a 50% share of the difference between the two accruals.

Can a court override an antenuptial contract on divorce?

The contract binds the spouses to the chosen regime, but a court retains discretion under section 8 of the Divorce Act 70 of 1979 to make a redistribution order if it would be just in the circumstances. An ANC substantially reduces the risk of such an order but does not make one impossible, particularly where the accrual system was excluded or where one spouse contributed in ways the contract did not anticipate.
