In South Africa, the main marriage property choices are marriage in community of property, marriage out of community of property with accrual, and marriage out of community of property without accrual. Couples who want to marry out of community of property usually sign an antenuptial contract before the wedding.
What is a prenup in South Africa?
A prenup in South Africa is the common name for an antenuptial contract (ANC), a contract executed before marriage that determines the spouses’ matrimonial property system. It is used to marry out of community of property, either with the accrual system or without it. Under section 2 of the Matrimonial Property Act 88 of 1984, accrual applies unless the ANC expressly excludes it.
Prenup, prenuptial agreement, ANC: what is the difference?
“Prenup” and “prenuptial agreement” are common everyday terms. “Antenuptial contract” and “ANC” are the South African legal terms usually used for the contract signed before marriage to regulate the spouses’ matrimonial property system.
The name matters less than the legal effect. A proper ANC should record whether the couple is marrying out of community of property with accrual or without accrual, and it must be handled through the correct notarial and registration process.
The three main marriage property systems
| Marriage system | Simple explanation | What to watch |
|---|---|---|
| In community of property | The spouses share one joint estate, including assets and liabilities, subject to the rules of the system. | Debt and financial risk can affect both spouses. |
| Out of community of property with accrual | Each spouse keeps a separate estate during the marriage, but growth in the estates is shared when the marriage ends. | Commencement values, exclusions, and estate growth must be understood before signing. |
| Out of community of property without accrual | Each spouse keeps a separate estate and does not share growth under the accrual system. | This can be appropriate for some couples, but may be unfair if one spouse sacrifices earning capacity. |
1. Marriage in community of property
If you get married without an antenuptial contract, the default position is usually marriage in community of property. This means the spouses share one joint estate, including assets and liabilities, subject to the rules that apply to that system.
For some couples this may be acceptable. For others, especially where there is business risk, debt exposure, family property, a trust, or an inheritance concern, it can create serious financial risk.
2. Out of community of property with accrual
Marriage out of community of property with accrual is often the middle path. Each spouse keeps a separate estate during the marriage, but the growth in the spouses’ estates is shared when the marriage ends.
The accrual system can work well where couples want protection for separate estates but still want a fair sharing of what is built during the marriage. It should be explained carefully before signing, especially where assets, businesses, inheritances, or commencement values need to be recorded correctly.
3. Out of community of property without accrual
Marriage out of community of property without accrual gives the strongest separation. Each spouse keeps a separate estate, and growth is not shared through the accrual system.
This may be appropriate for second marriages, substantial wealth differences, business risk, or specific estate-planning concerns. It can also produce a harsh result if one spouse earns less or gives up earning capacity during the marriage, so the choice should be made deliberately.
What makes an antenuptial contract valid?
An antenuptial contract is more than a template. If executed in South Africa, it must be attested by a notary and registered in a deeds registry within the required period, unless a court allows an extension.
Do you need a lawyer or a notary for a prenup in South Africa?
You do not always need a separate attorney for each person, but the ANC itself must be attested by an admitted notary public. A notary public is an attorney with additional admission to perform notarial work. Independent advice may be appropriate where the arrangement is complex, the estates are unequal or either person would benefit from advice on their own position.
Couples should obtain advice, agree the structure and execute the ANC before marriage. If the ANC is executed in South Africa, section 87 requires it to be tendered for registration within three months after execution unless a competent court allows an extended period. The official Constitutional Court record in VVC v JRM and Others [2026] ZACC 2 records the current framework. For the practical sequence, read how long an antenuptial contract takes. For tailored advice, drafting or notarial instructions, speak to SD Law’s antenuptial contract attorneys.
This is one reason couples should not leave the contract until the last moment. The agreement should be discussed, drafted, signed, and lodged correctly before the wedding creates avoidable pressure.
With accrual or without accrual?
The accrual system is often misunderstood. In simple terms, it allows spouses to keep separate estates during the marriage while sharing the growth of their estates if the marriage ends.
If a couple marries out of community of property under an antenuptial contract and does not expressly exclude accrual, the accrual system applies. Couples who want to exclude accrual must make that choice clearly in the ANC.
Can you sign a prenup after marriage?
An antenuptial contract is intended to be signed before marriage. If spouses are already married and want to change their matrimonial property system, that is not a simple late prenup. It is a formal legal process and generally requires a court route.
When should you get legal advice?
Get advice before signing if either spouse owns property, has a business, carries meaningful debt, expects an inheritance, has children from a prior relationship, or wants to exclude assets from accrual. A cheap or generic document may not deal properly with these facts.
For a tailored antenuptial contract or advice on the right matrimonial property system, speak to SD Law’s antenuptial contract attorneys.
