Antenuptial Contracts: What an ANC Settles Before You Marry

The wedding date was set, and the venue was booked. Then the planner mentioned you’d need to see a notary first. Not the marriage officer, but a notary. You’d assumed marriage was a single signature on the day. Now there was a separate document to sign before the ceremony. It came with a deadline nobody had explained, and a list of choices you hadn’t discussed.

That document decides something most couples never raise over dinner. It settles who owns what, and who owes what, once you’re married. Skip it, and the law makes the choice for you; sign it, and you’ve set the financial shape of the marriage. Here’s what it settles, and why the timing is so strict.

What is an antenuptial contract?

An antenuptial contract is a written agreement. A couple signs it before marriage, in front of a notary. It sets the property system that will govern the marriage. It lets a couple marry out of community of property, instead of the default. The Matrimonial Property Act 88 of 1984 governs how it works and what it can contain.

Key Takeaways

• Without an antenuptial contract, a South African marriage is automatically in community of property.
• An antenuptial contract lets a couple marry out of community of property, with or without the accrual system.
• The contract must be signed before the wedding, executed before a notary, and registered at the Deeds Office within three months.
• An unregistered contract binds the spouses but not their creditors, who can treat the marriage as in community of property.
• The accrual system shares the growth of both estates during the marriage unless the contract excludes it.
• Changing the regime after marriage needs a High Court application under section 21 of the Matrimonial Property Act.

What happens if you don’t sign one

Doing nothing is itself a decision, and the default it triggers surprises many couples. Under the Matrimonial Property Act 88 of 1984, a marriage with no antenuptial contract is automatically in community of property. That means one joint estate. Everything each spouse owned before the wedding falls into a shared pot. So does everything either earns afterward, and so do the debts. A creditor of one spouse can look to the joint estate. That includes the other spouse’s share.

In community of property also limits daily control. Some transactions need both spouses’ consent, such as selling a home or taking on large debt. And the insolvency of one spouse sequesters the joint estate. Both are exposed. For a couple where one runs a business, or carries old debt, that reach is real. Couples who aren’t marrying, but living together, face a different gap. That’s why a notarial cohabitation agreement exists. For those who are marrying, the point is plain. Silence hands the choice to the Act, and the Act merges everything.

What an antenuptial contract decides

An antenuptial contract chooses the property system, and there’s nothing romantic or distrustful about it. It moves the marriage out of community of property. Then it picks one of two arrangements. The first is out of community without accrual: each spouse keeps a fully separate estate, before and during the marriage. Neither shares the other’s growth or debt. The second is out of community with accrual, so the estates stay separate during the marriage. The growth is shared when the marriage ends.

The contract records the commencement value of each estate. That’s the starting line for measuring growth later. It also lists any assets a spouse wants excluded. A couple who later changes their mind faces a harder road, through a postnuptial contract. So the choice is best made carefully, before signing. For a property buyer, a business owner, or an heir-in-waiting, it shapes debt, divorce, and death. It’s a financial instrument dressed as wedding admin. The financial part is the part that lasts.

How the accrual system shares growth without merging estates

The accrual system answers a fair objection to full separation. One spouse may build wealth while the other builds the home. Under the accrual chapter of the Matrimonial Property Act, accrual applies by default to every out-of-community marriage, unless the contract excludes it. During the marriage, each estate stays separate, and each spouse manages and owes on their own. The sharing happens only at the end, on divorce or death.

At that point, the growth in each estate since the wedding is measured. The spouse whose estate grew less can claim half the difference. Excluded assets fall outside the sum, and so do inheritances and donations between the spouses. This is why the commencement values are written in. They’re the figures the calculation runs from, years later. For most couples who want fairness without one merged estate, accrual is the middle path. Exclude it on purpose, not by accident. Excluding it means no sharing of growth at all.

Why timing and the notary aren’t formalities

The wedding date and the notary are validity conditions, not box-ticking. Get them wrong, and the contract fails as an antenuptial contract. The agreement has to be signed before the marriage ceremony. An agreement signed after the wedding is not one at all. It also has to be executed before a notary public, a specially qualified attorney. The notary attests it. The notary then lodges it for registration at the Deeds Office. This is the notary’s role in marriage and family matters, and the law gives it real weight.

The deadline is the part couples miss. Under section 87 of the Deeds Registries Act 47 of 1937, a contract executed in South Africa must be registered within three months of execution. A court can extend that period. The notarial attestation requirement in the Deeds Registries Act is why a downloaded template signed at home achieves nothing. The notary’s attestation and the three-month window make the contract binding on the world. Not only on the two of you.

What an unregistered contract can and can’t do

A contract that misses registration doesn’t vanish. But it loses most of its power. Say the notary executed it, yet it wasn’t registered in time. The agreement still binds the two spouses between themselves. They’ve agreed how their estates work, and that agreement stands as a private contract. What it loses is force against third parties. A creditor who wasn’t a party can ignore it. As a De Rebus analysis of antenuptial contracts and third parties sets out, only a registered contract binds outsiders.

That gap is the dangerous one. The point of marrying out of community is usually to shield each spouse’s assets from the other’s creditors. An unregistered contract leaves that shield open. A couple who spots the lapse can apply to the High Court to register late. But that’s an application, with cost and uncertainty, not a right. The same court route handles endorsements after the death of a spouse and other corrections to the register. Register on time, and none of this arises.

Changing the regime after you’re already married

A married couple isn’t locked in forever. But switching systems is a court matter, not a fresh trip to the notary. Section 21 of the Matrimonial Property Act lets spouses apply jointly to the High Court. They can move from in community to out of community, or add or drop accrual. The court must be satisfied there’s good reason. It must be satisfied no creditor is prejudiced. And it needs notice to the registrar of deeds and to creditors.

This path is slower and more costly than getting it right before the wedding. That’s the practical case for deciding early. We cover changing your marital regime later on its own, because the procedure has several moving parts. For a couple weighing whether to bother before the date, the comparison is stark. A notarial signing and a registration fee now, against a High Court application later. The cheaper, surer step is the one taken before the marriage.

What the document protects

An antenuptial contract reads like wedding admin, and it works like a financial firewall. It decides whose debt stays whose, and whose growth gets shared. It decides what a creditor can reach if a business fails or a marriage ends. None of that feels urgent in the weeks before a wedding. That’s exactly why it’s so often left to the deadline, or skipped. The contract isn’t a comment on the relationship. It’s the line that holds when money, debt, or death tests the marriage years later.

You shouldn’t have to find out the document was signed too late, or never registered, when a creditor comes knocking. With Wilma Ewest Attorneys you won’t.

Contact Wilma Ewest Attorneys to have your antenuptial contract drafted, executed, and registered within the deadline that makes it binding.

Couples planning a wedding tend to ask the same practical questions once they understand what’s at stake. Here are the ones that come up most.

Frequently Asked Questions

What is the deadline to register an antenuptial contract in South Africa?An antenuptial contract executed in South Africa must be registered at a deeds registry within three months of the date the notary executed it. This deadline comes from section 87 of the Deeds Registries Act 47 of 1937. A court may extend it on application. The contract itself has to be signed before the wedding ceremony. Registration can then happen in the window after signing. If the three-month period passes without registration, the contract is no longer enforceable against third parties such as creditors. It may still bind the spouses between themselves. A contract concluded outside South Africa generally has a longer window of six months. Because the deadline is strict, and the consequences of missing it are serious, the notary who executes the antenuptial contract usually handles the lodgement and registration. That way the couple does not have to track the date themselves.Can you sign an antenuptial contract after getting married?No. An antenuptial contract must be signed before the marriage ceremony. A contract signed after the wedding is not a valid antenuptial contract. If a couple marries without a registered antenuptial contract, the marriage is automatically in community of property under the Matrimonial Property Act 88 of 1984. The only way to change the property system after the wedding is a joint application to the High Court. That application is brought under section 21 of the Act, for a postnuptial change. It requires good reason, proof that creditors will not be prejudiced, and notice to the registrar of deeds. This is more costly and less certain than signing before the marriage. For that reason, couples who want to marry out of community of property should arrange the contract with a notary well before the wedding date. Relying on a court correction afterwards is the harder path.What does an antenuptial contract with accrual mean?An antenuptial contract with accrual means a couple marries out of community of property but agrees to share the growth of their estates when the marriage ends. During the marriage, each spouse keeps a separate estate. Each is responsible for their own debts. When the marriage ends through divorce or death, the growth in each estate since the wedding is measured. The spouse whose estate grew less can claim half the difference. The accrual system is the default for marriages out of community under the Matrimonial Property Act 88 of 1984. So it applies automatically, unless the antenuptial contract expressly excludes it. The contract records the commencement value of each estate, which is the starting point for measuring growth. It also lists any assets the spouses want to exclude. Accrual is often chosen because it balances asset protection with fairness between spouses.Does an antenuptial contract protect you from your spouse’s debts?A registered antenuptial contract out of community of property generally protects each spouse from the other’s debts. The estates remain separate, so a creditor of one spouse cannot claim against the other’s estate. This protection depends on the contract being validly executed before a notary and registered at the Deeds Office within the required period. An antenuptial contract that is signed but not registered in time binds the spouses between themselves. It does not protect them against third parties, so a creditor can still treat the marriage as in community of property. The protection is also not absolute. A spouse who signs surety for the other, or who incurs joint debt, can still be liable. For couples where one runs a business, or carries financial risk, a properly registered antenuptial contract is the main tool for keeping that risk on one side of the marriage.
