Key Features of a Marriage Out of Community of Property

A marriage out of community of property in South Africa is one in which the spouses retain separate estates under the Matrimonial Property Act 88 of 1984 — there is no community of property between the spouses and no accrual sharing unless the antenuptial contract expressly provides for the accrual system. To be valid, the antenuptial contract must be signed by both intending spouses in the presence of a Notary Public before the marriage takes place, and must be lodged for registration at a Deeds Registry within the prescribed period after the wedding. Spouses who marry without an antenuptial contract default into a marriage in community of property, where all assets and liabilities are pooled into a joint estate — the out-of-community route therefore requires affirmative legal action in advance of the wedding, not after it.

The Default Rule and Why an Antenuptial Contract Is Needed

Under South African law, marrying without an antenuptial contract results in a marriage in community of property — a single joint estate in which both spouses share everything equally on divorce or death. Section 3 of the Matrimonial Property Act 88 of 1984 governs marriages in community of property, and section 21 of the same Act governs the exclusion of community of property by antenuptial contract. The Act is the controlling statute for matrimonial property regimes in South Africa and applies uniformly across the country.

An antenuptial contract is the legal mechanism by which intending spouses opt out of the default regime before the marriage. Both intending spouses must sign the contract in the presence of a Notary Public before the wedding. A contract signed after the marriage cannot retrospectively change an existing matrimonial property regime — although post-nuptial relief is available in limited circumstances under section 21(1) of the Act by way of a formal application to the High Court. Where a couple has already married without an antenuptial contract and now wishes to convert their regime, they must approach the High Court for leave rather than simply signing a fresh document.

Why this matters in practice

Many couples assume they will get around to an antenuptial contract “later” or that the wedding planner can refer them somewhere on the day. In fact, the Notary must witness both signatures before the marriage takes place. Booking the Notary appointment well in advance of the wedding is the most common practical lesson couples learn when researching this option.

What “Out of Community of Property” Actually Means

Each spouse retains a separate estate. Assets owned before the marriage remain that spouse’s alone, and assets acquired after the marriage belong to the spouse who acquired them — at least in the absence of an accrual clause. Each spouse manages and controls their own property independently, and the other spouse does not need to consent to a sale, mortgage, or investment in the separate estate.

Liabilities are also separate. Debts incurred by one spouse do not automatically attach to the other spouse’s estate. The limited exception is household necessities under section 18 of the Matrimonial Property Act, where a spouse may be held liable for debts incurred by the other for household necessities where the contributing spouse has failed to make a reasonable contribution.

The Two Variants: Without Accrual vs With Accrual

There are two distinct flavours of marriage out of community of property, and the choice between them is made when the antenuptial contract is signed.

Without accrual

This is the default out-of-community position. Each spouse keeps what they brought into the marriage and what they earned during it; on divorce or death, there is no sharing of growth in the estates. It is the cleanest separation of property and is often chosen where one party enters the marriage with established assets, a family business, or expected inheritances.

With accrual

The spouses agree to share the growth in their respective estates during the marriage. The calculation runs from the date of marriage to the date of divorce or death, but excludes inheritances, donations, and personal-damages awards. The spouse with the smaller net accrual has a claim against the other for half the difference. The accrual system does not pool the estates themselves — it only equalises growth on dissolution.

Custom clauses

Either variant can be further customised by special clauses. Common customisations include excluding a specific asset from the accrual calculation, fixing a particular asset’s value at marriage for accrual purposes, or ring-fencing a family-business interest. Couples approaching a second marriage, a family-business owner, or anyone with a pre-marital asset they want to protect should raise these points with their Notary before signing — once the contract is executed, changes are difficult and may require a High Court application.

The Role of the Notary Public and the Registration Step

Antenuptial contracts must be executed by both intending spouses in the presence of a Notary Public, in South Africa. The Notary explains the legal effect of the contract to both parties, witnesses the signatures, and prepares the contract for registration in a Deeds Registry. After the marriage, the Notary lodges the contract together with the marriage certificate at the Deeds Registry — registration must occur within the prescribed period after the marriage for the contract to be effective against third parties.

Failure to register within the prescribed period does not invalidate the contract between the spouses, but it leaves third parties — creditors, purchasers, and other counterparties — without notice and unprotected by the contract’s terms. For couples who later want to bind a creditor or to claim against a third party in terms of their separate estates, late registration can be a real obstacle.

What Changes on Divorce

The property consequences on divorce flow directly from the matrimonial property regime chosen at the outset.

• Marriage out of community without accrual — each spouse retains their own estate in full on divorce; there is no sharing of growth or assets acquired during the marriage.
• Marriage out of community with accrual — a calculation of net accrual is performed across the duration of the marriage, and the spouse with the smaller accrual has a claim against the other for half the difference, enforceable as part of the divorce settlement under the Divorce Act 70 of 1979.
• Maintenance and care arrangements for minor children are determined independently of the property regime, under the Divorce Act 70 of 1979 and the Children’s Act 38 of 2005.
• Constructive-trust or unjust-enrichment claims — a spouse married out of community without accrual who has contributed to the other’s estate or to household needs may still have a claim under the constructive-trust doctrine or unjust enrichment. These are fact-specific and do not arise from the antenuptial contract itself.

What Changes on Death

Each spouse may dispose of their separate estate by will, subject to the maintenance claims of dependants under the Maintenance of Surviving Spouses Act 27 of 1990. In a marriage with accrual, the surviving spouse has an accrual claim against the deceased spouse’s estate if the deceased’s net estate grew more than the survivor’s during the marriage.

The antenuptial contract should be reviewed alongside any will to ensure consistency — particularly where one spouse wishes a particular asset to pass outside the accrual calculation or to a beneficiary other than the surviving spouse. Couples often sign an antenuptial contract years before drafting a will, and the two documents can drift out of step. A short will review at the same time as any major change to the antenuptial contract is a worthwhile habit.

Frequently Asked Questions

Can I sign an antenuptial contract after I am already married?

Generally no — an antenuptial contract must be signed by both parties in the presence of a Notary Public before the marriage takes place. Couples who married without an ANC and now wish to change the regime can apply to the High Court under section 21(1) of the Matrimonial Property Act 88 of 1984 for permission to register a post-nuptial contract, but the court will only grant this on good grounds and will protect the interests of creditors and others affected.

Does marriage out of community of property mean everything my spouse earns belongs to them?

Yes, by default. Without the accrual system, each spouse retains the assets they acquire during the marriage in their own separate estate. If the couple want growth in the marriage to be shared on divorce or death, the antenuptial contract must specifically include the accrual clause.

What does an antenuptial contract cost in South Africa?

Fees depend on the complexity of the contract — a straightforward without-accrual contract is cheaper than one with accrual plus custom clauses — and on the Notary’s professional fee schedule. Burger Huyser Attorneys’ notaries on staff can quote after an initial consultation; the total cost typically comprises the Notary’s professional fee plus a Deeds Registry registration fee, with no hidden disbursements.

Do I need to register the antenuptial contract after the marriage?

Yes — the contract must be lodged in a Deeds Registry within the prescribed period after the marriage for it to be effective against third parties. The contract is valid between the spouses without registration, but third parties such as creditors and purchasers are not bound by unregistered contracts.

Is marriage out of community of property better for protecting assets?

It provides clearer separation of estates, which can be useful for second marriages, business owners, or couples whose families have particular assets to protect. It is not better in any absolute sense — whether out of community (with or without accrual) suits a couple depends on their circumstances, and each spouse should understand the implications before signing. Consulting an attorney and Notary before the wedding is essential.

What happens to debt in a marriage out of community of property?

Each spouse is generally responsible only for their own debts. The exception is household necessities — under section 18 of the Matrimonial Property Act, a spouse may be held liable for debts incurred by the other for household necessities if they fail to contribute reasonably.
