How Do I Change My Marital Property Regime In South Africa?

Changing a marital property regime after marriage in South Africa is only possible by way of a formal joint application to the High Court under Section 21 of the Matrimonial Property Act 88 of 1984 (as substituted by section 4 of the Matrimonial Property Amendment Act 95 of 1988). The court will only grant the order if there are sound reasons for the change and the interests of the spouses’ creditors are not unreasonably prejudiced — or, if they would be, if the court orders that the creditors be paid first or that the new regime does not affect existing debts. At least two months must run from the date of last publication before the court may grant the order; a clean unopposed application typically takes three to six months from start to registration.

The Legal Framework: Section 21 of the Matrimonial Property Act

The Matrimonial Property Act 88 of 1984 governs matrimonial property regimes in South Africa. Section 21 (as substituted by section 4 of the Matrimonial Property Amendment Act 95 of 1988) is the only statutory mechanism for changing a regime after marriage — a single, closed route that cannot be sidestepped by private agreement. The change is not a Home Affairs registration update and not a notarial amendment on its own: it is a High Court order, and the change only takes effect once the order is granted and the new (or amended) antenuptial contract is executed before a notary and lodged with the Registrar of Deeds. The court’s discretion is broad — even where the two statutory requirements are met, the court may refuse an order if it is not just and equitable to grant it.

The Two Statutory Requirements

Sound reasons for the change

The applicant spouses must set out, in their founding affidavit, the reasons why the change is sought. South African courts have accepted motives that include changed personal circumstances, estate planning, family-business protection, negating or acceding to the accrual system, tax planning, and creditor-risk management. The reasons must be particular to the spouses — generic statements that any couple might make are unlikely to carry the application on their own.

No unreasonable prejudice to creditors

The court must be satisfied that the change will not unreasonably prejudice the spouses’ creditors, or that any prejudice can be mitigated. The Act allows the court to order that existing debts be paid first from the joint estate before the new regime takes effect, or that the new regime does not vary the position of any existing creditor. Motive matters: courts have rejected Section 21 applications where the dominant purpose appeared to be defrauding creditors or stalling enforcement by an existing creditor.

What “Changing” the Regime Can Mean

A Section 21 application can do more than switch a couple from one regime to another. The four common scenarios are:

Scenario	What the application does
Switching from in-community to out-of-community	The most common change — moves the spouses out of the joint estate. Frequently driven by the financial exposure of the joint estate, particularly for entrepreneurs and professionals.
Adding or removing the accrual system	Switches between out-of-community-without-accrual and out-of-community-with-accrual (or vice versa). The accrual rules are the same as those that apply to marriages concluded out-of-community under the default consequences of the Act.
Modifying specific ANC terms	Narrower changes to particular clauses of an existing ANC — replacing a forfeiture clause, adjusting the accrual-sharing percentage, or changing an income-and-expenditure carve-out.
Customary marriages	Spouses in a customary marriage can also apply; the change still runs through Section 21 of the same Act.

The Section 21 Application, Step by Step

The procedural sequence is fixed by the Act and the Uniform Rules of Court:

1. Joint decision to apply. Both spouses must be applicants — the application cannot be brought by one spouse against the other’s wishes.
2. Draft the new (or amended) antenuptial contract. A notarial contract specifying the new regime, with all required formalities including notarial execution.
3. Identify and notify all known creditors of the joint estate (or of either spouse, depending on the regime).
4. Arrange statutory publication in the Government Gazette and in a newspaper circulating in the district where the spouses reside. The two-month waiting period runs from this publication.
5. Prepare the court application: Notice of Motion, Founding Affidavit deposed to by both spouses, supporting annexures (marriage certificate, existing ANC, asset and liability schedules, draft new contract, proof of creditor notification, proof of publication), and a draft order.
6. File at the High Court with jurisdiction — the division where the spouses reside, where the marriage is registered, or where the spouses’ immovable property is situated.
7. Wait out the two-month waiting period. The court will not grant the order before the period has expired from the date of last publication.
8. Set the matter down for hearing — for an unopposed application, a single appearance on the motion court roll.
9. Execute and register the new ANC. Once the order is granted, the new ANC must be executed before a Notary Public and lodged with the Registrar of Deeds. If not completed within three months of the order, it lapses automatically.

Documents You Will Need

At the first consultation with your attorney, expect to assemble the following — the application itself will rely on each of them:

• Existing marriage certificate (or written confirmation of marriage registration from the Department of Home Affairs)
• Existing antenuptial contract, if any, and confirmation of the current matrimonial property regime on record at Home Affairs
• Full schedule of assets and liabilities of both spouses
• Draft new (or amended) antenuptial contract, drawn by a notary
• List of all known creditors of the joint estate and of each spouse
• Proof of written notice to creditors
• Proof of publication in the Government Gazette and in a newspaper circulating in the district
• Founding Affidavit and supporting annexures
• Draft order, suitable for signature by the presiding judge

Notice Requirements in Detail

The notice layer is statutory, not optional. Before the court will grant the order, the Act requires:

• Both spouses as joint applicants on the application.
• Written notice to every known creditor of the joint estate and of each spouse.
• Publication in the Government Gazette.
• Publication in a newspaper circulating in the district where the spouses reside.

The two-month waiting period runs from the date of publication — in practice, the later of the Gazette and the newspaper. The court may waive the notice requirements in limited circumstances, but rarely does, and an applicant without a proper notice record should expect the application to be stood over rather than granted.

After the Court Order

Once the order is granted, the file moves into the registration layer:

1. Execute the new ANC before a Notary Public — a notary must be involved because the change overrides the joint estate.
2. Lodge the new ANC with the Registrar of Deeds for the relevant district.
3. Update the marriage register at the Department of Home Affairs, where applicable.
4. Complete all of the above within three months of the date the order was granted — otherwise the order lapses automatically and a fresh Section 21 application has to be brought from scratch.

Costs include attorney’s fees, notary’s fees, court filing fees, and Government Gazette and newspaper publication fees. Burger Huyser Attorneys quotes on a per-file basis after the eligibility review at the relevant branch.

Common Reasons That Have Been Accepted (and Rejected)

South African courts have built up a body of guidance on what counts as a “sound reason” under Section 21. The contrast between accepted and rejected applications is instructive:

Accepted by the courts	Rejected by the courts
Estate planning in the context of a family business	Primary motive of defrauding an existing or anticipated creditor
Structural reorganisation of an inheritance	Vague or generic reasons without supporting facts
Correcting an oversight at the time of marriage	Cases where the change would substantially diminish the security of an existing creditor with no compensating provision
Negating the accrual system to protect an inheritance received during the marriage	—
Acceding to the accrual system to share growth between the spouses	—

The takeaway: the reasons must be particular to the spouses, supported by facts on the founding affidavit, and they must not undermine the position of any creditor.

What the Order Does and Does Not Do

• The order runs prospectively — the new regime takes effect from registration of the new ANC, not from the date of marriage.
• The court can direct that the change does not affect the rights of any existing creditor, or that the spouses’ existing debts be paid first from the joint estate before the new regime takes effect.
• The order does not reverse prior transactions — asset transfers already executed under the old regime remain in place, subject to the normal rules around creditors’ rights.
• The order does not retrospectively affect the spouses’ accounting between themselves for the period before the change.

Why This Process Cannot Be Skipped

Section 21 of the Matrimonial Property Act is the only route. A notarial amendment to an existing ANC that purports to change the regime itself does not have legal effect until confirmed by a court order, and couples who try to “restructure” through a cohabitation agreement or a notarial deed alone will find that the change is not recognised for any subsequent legal purpose — property transfers, divorce, or insolvency will all default back to the regime on record.

Practical Considerations: Cost, Timeline, What to Bring

Three variables drive almost every conversation about a Section 21 application: cost, time, and what is needed at the first consultation.

Variable	What to expect
Cost	Fees depend on complexity and whether the application is opposed. A clean, unopposed Section 21 application typically runs from approximately R25,000 to R60,000 in attorney fees, plus notary fees, court filing fees, and publication costs. Burger Huyser Attorneys quotes on a per-file basis after the eligibility review at the relevant branch.
Timeline	At least two months from publication to grant. Clean unopposed applications typically resolve within three to six months. Applications that attract correspondence from creditors or other interested parties can run considerably longer — a year or more is not unusual in an opposed matter.
What to bring	Marriage certificate, existing ANC (if any), confirmation of the current matrimonial property regime from the Department of Home Affairs, a list of all known creditors, and a draft of the proposed new regime.

Sound reasons particular to the spouses, supported by documentary evidence, and a properly executed publication record are what get an order granted. The firm handles Section 21 applications as part of its Family Law and antenuptial-contract practice, with files run through the appropriate branch.

Frequently Asked Questions

Can you change your marital property regime after marriage in South Africa?

Yes — but only by way of a joint High Court application under Section 21 of the Matrimonial Property Act 88 of 1984. There is no other statutory route, and the order will only be granted if there are sound reasons for the change and no unreasonable prejudice to creditors.

How long does the Section 21 application take?

At least two months from the date of the last required publication in the Government Gazette and in a newspaper circulating in the district. Clean, unopposed applications typically resolve within three to six months. Opposed applications can run considerably longer.

Do both spouses need to agree to the change?

Yes. Both spouses must be joint applicants. A Section 21 application cannot be brought by one spouse against the other’s wishes.

Can we change the regime without going to court?

No. Section 21 of the Matrimonial Property Act requires a court order. A notarial deed alone does not change the regime; the new ANC is only effective once it is registered after the order is granted.

How much does it cost to change a marital property regime in South Africa?

Cost depends on complexity. A clean, unopposed Section 21 application typically runs from approximately R25,000 to R60,000 in attorney fees, plus notary fees, court filing fees, and Government Gazette and newspaper publication fees. Burger Huyser Attorneys quotes on a per-file basis after the initial eligibility review.

Will the change affect existing creditors?

The court will usually direct either that existing creditors are paid first from the joint estate, or that the change does not affect the rights of any existing creditor. The order runs going forward, not retrospectively, and prior transactions under the old regime remain in place.

What happens if we don’t register the new ANC within three months of the order?

The order lapses automatically. The new ANC must be executed before a notary and lodged for registration within three months of the date the order was granted. If the deadline is missed, a fresh Section 21 application has to be brought from the beginning.
