Antenuptial law in Johannesburg governs the matrimonial property regime a couple will live under during their marriage. Before the wedding, each couple must choose between marriage in community of property and marriage out of community of property, and that choice is recorded in an antenuptial contract. The decision has consequences that run for the life of the marriage and beyond, affecting assets, debts, estate planning, and the position of creditors.
The governing statute is the Matrimonial Property Act 88 of 1984, which reformed South African marital property law and introduced the accrual system. An antenuptial contract, properly signed before a notary and registered at the Deeds Office, excludes the default community of property regime and replaces it with the terms the couple have agreed to.
What an antenuptial contract actually does
An antenuptial contract, or ANC, is a written agreement entered into by two people before they marry. Its core function is to exclude community of property and community of profit and loss between the spouses. Without an ANC, a civil marriage in South Africa automatically defaults to in community of property, which means the spouses acquire a single joint estate made up of all their assets and liabilities, whenever acquired.
By signing an ANC, the couple replaces that default with their own regime. Each spouse keeps a separate estate, and the contract can identify specific assets that will remain excluded. The Matrimonial Property Act 88 of 1984 sets the framework, but the practical terms, what is excluded, whether accrual applies, and how specific assets are treated, are shaped by the couple and the notary who drafts the deed.
The two types of antenuptial contract
South African law recognises two forms of marriage out of community of property, and the choice between them is the most important drafting decision in an ANC. The difference lies in how growth in the spouses’ estates during the marriage is treated. An important aspect of marital law is section 7(3) divorce act overview, which provides insight into the treatment of assets in the event of a divorce. This section is crucial for understanding how the division of property will affect each spouse’s financial position. Legal advice is often recommended to navigate these complexities effectively. Divorce laws in South Africa are designed to protect the rights of both parties, ensuring a fair and equitable distribution of assets. It is essential for couples to understand these laws before entering into any agreement. Seeking professional legal counsel can make a significant difference in how assets and liabilities are managed during and after marriage.
- Out of community of property with accrual. Each spouse keeps a separate estate during the marriage, but when the marriage ends through divorce or death, the growth in each estate from the date of marriage is calculated and the spouse whose estate grew less acquires a claim against the other for half of the difference. The accrual system was introduced by the Matrimonial Property Act 88 of 1984 to soften the financial hardship that a pure separation of estates could cause.
- Out of community of property without accrual. The spouses keep completely separate estates. There is no sharing of growth at the end of the marriage, and each party walks away with what is in their own name. This regime offers the strongest protection where one spouse brings a substantial business, inheritances, or professional risk into the marriage.
The accrual system is the default position under the Act for couples marrying out of community of property without an ANC executed before the Act commenced in 1984. For modern couples, the choice is made expressly in the contract, and the notary will record the opening values of each estate and any excluded assets so that the accrual calculation is clean if it ever has to be performed.
Why the contract must be signed before the marriage
Timing is the single most unforgiving requirement in antenuptial law. The ANC must be signed by both parties before the marriage is solemnised. Once the marriage is registered, the default regime, in community of property for couples who signed nothing, applies, and it cannot be reversed by a retrospective agreement.
This is why couples in Johannesburg are well advised to see a notary weeks, not days, before the wedding. The notary has to take instructions, draft the deed, confirm the parties’ identities and marital status, and have both parties execute in front of the notary and two competent witnesses. The contract then has to be lodged at the Deeds Office for registration within the prescribed period.
The role of the notary and the Deeds Office
An antenuptial contract is not a private document that takes effect between the spouses alone. To be opposable against third parties such as banks and creditors, it must be executed before a notary public and registered at the Deeds Office. A notary is an admitted attorney with an additional notarial practice qualification, admitted by the High Court.
Once executed, the ANC is lodged for registration at the relevant Deeds Office, in Johannesburg that is the Pretoria Deeds Office, which serves the Gauteng region. Registration gives the contract its public character. Third parties searching the Deeds Office records can see that the marriage is out of community of property and on what terms, which is what allows a spouse to contract, borrow, and transact in their own name without the presumption of a joint estate.
Changing an antenuptial contract after marriage
A common question is whether a couple can change their matrimonial property regime after they have married. Section 21 of the Matrimonial Property Act 88 of 1984 allows spouses to apply to court for an order changing their matrimonial property system, including by registering a postnuptial contract. This is the only lawful route to a postnuptial change in South Africa.
The court has a discretion and will grant the application only where specific safeguards are met. The applicants must show that there are sound reasons for the proposed change, that sufficient notice has been given to all creditors, and that no other person will be prejudiced. The court must also be satisfied that the change is consistent with the protection of creditors and the public interest. Because creditors can object, the process is not a formality, and proper legal representation is essential.
This section 21 route is sometimes used to move from in community of property to out of community of property, or to switch between the accrual and non-accrual variants, after the marriage has begun. It is not, however, a way to undo the consequences of an ANC that a spouse has simply come to regret.
The risks of doing nothing
Where no ANC is signed before the marriage, the couple is automatically married in community of property. The consequences are significant and often misunderstood.
- One joint estate. All assets and all liabilities of both spouses, whenever acquired, fall into a single joint estate, regardless of whose name they are in.
- Joint liability for debts. Each spouse is liable, jointly and severally, for the debts of the other, including debts that were incurred before the marriage.
- Consent requirements. A spouse cannot deal with certain joint assets without the other’s consent, which can constrain business and investment decisions.
- Estate complications on death. The joint estate is wound up together on the death of the first spouse, which can complicate estate planning and the rights of heirs.
These outcomes are exactly what the ANC is designed to avoid. Proper antenuptial advice, taken in time, lets a couple choose the regime that fits their circumstances rather than accepting the default.
Antenuptial law as part of Family Law
Antenuptial law sits within the broader discipline of Family Law. It interacts with divorce law, the law of succession, and the law of contractual capacity. The same attorney who drafts an ANC is often the person who later advises on its effect in a divorce, on a deceased estate, or in a dispute with a creditor, which is why continuity of advice matters.

Frequently Asked Questions
What is an antenuptial contract under South African law?
An antenuptial contract, or ANC, is a written agreement signed by two people before they marry that excludes community of property and community of profit and loss between them.

What is the difference between an ANC with and without accrual?
With accrual, each spouse keeps a separate estate during the marriage but at the end of the marriage the growth in each estate is compared and the spouse whose estate grew less acquires a claim for half of the difference. Without accrual, the spouses keep completely separate estates and there is no sharing of growth at the end of the marriage.
