Most couples spend months planning the wedding and about ten minutes on the paperwork that decides who owns what for the next forty years. In South Africa, your marital property regime is either chosen before the wedding or handed to you by default, and it affects your debts, your home, your savings, your inheritance and what happens if the marriage ends.
This guide explains the three main regimes in plain language, the one deadline that catches people out, and the money questions each regime raises. It is general information and not legal advice, and an attorney or notary should draw up any contract.
The key points:
- If you marry without an antenuptial contract, you are generally married in community of property. That includes customary marriages concluded since November 2000.
- An antenuptial contract must be signed before the wedding and registered at the deeds registry within three months.
- Out of community of property usually comes with the accrual system, because it applies unless your contract expressly excludes it.
- Your regime decides whose estate can be reached for a debt and who must consent to big transactions.
- You can talk about money as a couple whichever regime you are in.
What does in community of property mean?
In community of property, everything you each own and owe is combined into a single joint estate when you marry, and anything either of you earns or acquires afterwards joins it. You each own half of that joint estate. As a general rule, the joint estate can be held liable for debts that either of you incurs during the marriage, so a debt your spouse takes on can reach assets that feel like yours.
Some big decisions need the other spouse to agree. Under section 15 of the Matrimonial Property Act, you generally need your spouse's written consent to sell or mortgage immovable property in the joint estate, and to stand surety for someone else's debt. There are exceptions, including some transactions made in the ordinary course of a spouse's business. If one spouse is sequestrated (declared insolvent), the joint estate is generally sequestrated too, which in practice means both spouses are affected.
This is the default if you marry without a contract. It can suit couples who see their finances as fully shared, but it carries a risk. If one of you runs up debt, the whole joint estate can be exposed.
What does out of community of property mean?
Out of community of property, you keep separate estates. What you owned before the marriage and what you earn or acquire during it stays yours, and your debts are generally your own. To marry out of community of property, you need an antenuptial contract, which must be signed in front of a notary before the wedding.
Separate does not mean no shared responsibility. Under section 23 of the Matrimonial Property Act, spouses married out of community are jointly and severally liable to third parties for debts incurred for joint household necessaries, such as groceries, rent or school costs. They are also expected to contribute to those costs in proportion to their means.
There are two common versions of the contract. In the first, you exclude community of property, community of profit and loss and the accrual system, so your estates stay completely separate for the whole marriage and any divorce. In the second, you exclude community but leave the accrual system in place. This is the default: a marriage out of community of property under a contract that excludes community of property and community of profit and loss is subject to the accrual system, unless the contract expressly excludes it (section 2 of the Act). So if your contract is silent on accrual, accrual applies.
How does the accrual system work?
The accrual system lets each spouse's estate stay separate during the marriage but shares the growth in value when the marriage ends, by divorce or death. Each spouse's accrual is the amount by which the net value of their estate at the end of the marriage exceeds its net value at the start. The spouse with the smaller accrual, or none, can claim half of the difference. You have no claim on your spouse's estate during the marriage, only when it ends.
Take a simple example. Sipho's estate grows by R800,000 during the marriage and Naledi's by R200,000. The difference is R600,000, so Naledi can claim half of it, which is R300,000.
Four details change the numbers:
- Inflation. The value of each estate at the start of the marriage is adjusted for changes in the value of money, using the consumer price index. Growth that only keeps pace with inflation is not counted as accrual.
- Inheritances and donations. An inheritance, legacy or donation you receive during the marriage is excluded from your accrual, unless the contract or the person leaving or giving it says otherwise. A donation between spouses is also left out.
- Damages. Compensation for non-patrimonial loss, such as pain and suffering, is left out.
- Assets named in the contract. The contract can exclude particular assets, such as a family business, so settle this with your notary before the wedding.
On the death of a spouse, the accrual is worked out before the will or the intestate rules take effect, so the surviving spouse's claim is dealt with before the will takes effect. A lawyer should confirm how the calculation applies to your contract.
What is the three-month deadline?
An antenuptial contract signed in South Africa must be attested by a notary and registered in a deeds registry within three months of signing, or within a longer period that a court allows on application (section 87 of the Deeds Registries Act). If it is not registered, it has no force against anyone who is not a party to it. Your spouse is bound, but your creditors are not, so a third party can treat the contract as if it did not exist.
If the three months pass, the fix is a court application, either for an extension under section 87 or for permission to sign a postnuptial contract under section 88. Courts have noted that signing a fresh contract before the wedding is often easier than fixing a late one, so ask your notary for proof of registration, not just the signed copy. A deeds office may also ask how you are married when you buy or sell property.
What if you married under customary law?
A customary marriage concluded since the Recognition of Customary Marriages Act took effect in November 2000 is in community of property by default, unless the spouses excluded it in an antenuptial contract. The timing matters. In VVC v JRM (21 January 2026), the Constitutional Court held by a majority that a contract signed after a customary marriage, even if signed before a later civil wedding between the same people, was in substance a postnuptial contract. Without a court order under section 21 of the Matrimonial Property Act it was invalid, and the couple stayed married in community of property. If you plan a civil wedding after a customary one, get legal advice before signing anything.
Can you change your regime later?
Yes, but not casually. A married couple can apply to the High Court to change their marital property system. The court must be satisfied that there are sound reasons for the change, that sufficient notice has been given to all the creditors of both spouses, and that no one else will be prejudiced (section 21). It is a process you want to avoid needing.
How do the regimes affect everyday money?
- Debt. In community of property, the joint estate can be reached for either spouse's debts. Out of community, debts are generally the debtor's own, apart from household necessaries.
- Buying a home. Lenders will ask which regime applies, and in community of property you generally need your spouse's written consent to mortgage or sell the home. The guides to saving for a house deposit and how much home loan you can afford cover the money side.
- Business. If one of you runs a business, separate estates can keep the other spouse's savings and home further from business debts. They are not a shield in every case: if one spouse is sequestrated, a trustee can take control of the other spouse's property until that spouse proves it is theirs (section 21 of the Insolvency Act).
- Death. The regime decides what forms part of your estate. Combined with a will, it determines who inherits, as the guide to wills and estate duty explains.
How should couples talk about money whichever regime they have?
The regime is a legal frame, and it does not replace agreeing how you will handle money day to day. Decide who pays for what, whether you pool part of your income, how you will handle debt you bring into the marriage and how much each of you can spend without asking. The guide to budgeting as a couple gives you a way to start the conversation.
How can Budget Hub help?
Budget Hub profiles are personal, so each partner can track their own income and spending, which suits a separate-estates marriage and still lets you compare notes. You can record your own debts in the expense categories for credit cards, store accounts and personal loans, and see how much of your month goes to debt. If you are saving together for a deposit or a wedding, set it up as a savings goal with a target amount and date. The free plan includes three goals.
Quick answers
What is the default marital regime in South Africa?
If you marry without an antenuptial contract, you are generally married in community of property. This also applies to customary marriages concluded since November 2000.
When must an antenuptial contract be registered?
Within three months of signing, at the deeds registry, unless a court allows a longer period. An unregistered contract does not bind third parties such as creditors.
Is the accrual system the default out of community of property?
Yes. If your contract excludes community of property and community of profit and loss but says nothing about accrual, the accrual system applies.
What does the accrual system do?
It keeps your estates separate during the marriage and shares the growth in value when the marriage ends, with the spouse who gained less claiming half of the difference. The starting values are adjusted for inflation, and inheritances and donations are generally left out.
