Antenuptial Contract With Accrual In South Africa Explained

An antenuptial contract (ANC) with the accrual system in South Africa is executed by both parties in the presence of a notary public before the marriage takes place, in terms of section 2 of the Matrimonial Property Act 88 of 1984, and is then registered at the Deeds Office in the prescribed window after the marriage under the Deeds Registries Act 47 of 1937. The contract takes the marriage out of community of property, so each spouse retains a separate estate, but activates the accrual system under section 4 of the Act — at dissolution of the marriage (death or divorce) each spouse’s estate is valued as at the date of marriage and as at the date of dissolution, the difference is that spouse’s accrual, and the spouse whose accrual is smaller may claim half the difference from the other. The default is the in-community regime, so couples who do not execute an ANC before the marriage cannot retrospectively opt into the accrual system without a High Court application under section 21 of the Act.

What “Antenuptial Contract with Accrual” Actually Means

An ANC with accrual is one of three matrimonial property regimes available in South Africa. The alternatives are marriage in community of property (the default, no ANC required) and marriage out of community of property without accrual (ANC signed, but the accrual clause omitted). “Out of community of property” means each spouse retains a separate estate — assets owned before the marriage and assets acquired during the marriage stay in the spouse’s own name, and creditors of one spouse cannot reach the other spouse’s separate estate. “With the accrual clause” adds a sharing mechanism on dissolution: the growth of each spouse’s estate during the marriage is pooled, with the spouse whose estate grew less claiming half the difference from the other.

This regime is popular with couples who want to keep their pre-marital assets and any business interests separate, but who also accept that the wealth built up during the marriage belongs to both of them and should be shared on divorce or death. The accrual system is the middle path between the default (everything shared from day one) and the pure separation regime (no sharing at all).

The Three Matrimonial Property Regimes Compared

Regime	Estate ownership during marriage	Sharing on dissolution	How it is set up
In community of property (default)	Single joint estate; each spouse owns an undivided half of everything	No further sharing — the joint estate is already split 50/50	No contract required; the law applies by default
Out of community of property (without accrual)	Each spouse retains a separate estate	No sharing on dissolution — what each built stays theirs	ANC signed before marriage, with no accrual clause
Out of community of property with accrual	Each spouse retains a separate estate	Spouse with smaller accrual claims half the difference of the two accruals	ANC signed before marriage, with the accrual clause included

The Legal Framework: Matrimonial Property Act 88 of 1984

The Matrimonial Property Act 88 of 1984 is the single statute that governs all three regimes. The sections most couples and their attorneys work with are:

• Section 2 — the parties to a contemplated marriage may enter into an ANC that establishes their future matrimonial property regime.
• Section 3 — an ANC may exclude the community of property and the marital power, in whole or in part.
• Section 4 — the parties may include the accrual system, which is the sharing mechanism described above.
• Section 5 — sets out the effects of the marriage out of community of property on the estates of the spouses.
• Sections 6 to 8 — define the value of each spouse’s estate at the commencement and dissolution of the marriage, and how the accrual claim is calculated.
• Section 9 — provides for the settlement of the accrual claim on dissolution.
• Section 10 — regulates donations between spouses during the marriage.
• Section 21 — sets out the post-marriage variation procedure, which requires a High Court application and notice to creditors; this is the only way to change regimes after the marriage, and it is materially more involved than executing an ANC before the marriage.

South African courts have continued to develop the law around these sections — particularly around judicial discretion to vary the default 50/50 accrual share on fairness grounds, and around the treatment of a spouse who left the workforce to care for children. The contract is the starting point, but the case law on top of it is what determines how the regime plays out in an actual dissolution.

The Process, Step by Step

The full sequence from the first consultation to the confirmed Deeds Office registration runs as follows:

1. Pre-marriage consultation with the attorney — confirm the regime the parties want (out of community with accrual is the most common hybrid), discuss which assets should be excluded from the accrual calculation (inheritances, donations, pre-marital assets), and identify any tax or estate-planning implications.
2. Drafting the ANC — the attorney prepares the contract, including the accrual clause, the parties’ details, and any express exclusions or inclusions. Standard ANCs are typically a few pages; ANCs with bespoke exclusions, business-interest provisions, or prior-marital settlements run longer.
3. Execution before the notary — both parties sign the ANC in the presence of a single admitted notary public, who then attests the contract. This must happen before the marriage takes place — there is no “postnuptial contract” in the simple form.
4. Marriage — the parties marry, in any form recognised by South African law (civil marriage, religious marriage recognised under the Marriage Act 25 of 1961, civil union). The marriage triggers the registration deadline for the ANC.
5. Lodgement at the Deeds Office — the notary lodges the attested ANC for registration at the Deeds Office in the province where the marriage took place (or where the parties are domiciled). The registration is what gives the contract force as the matrimonial property regime.
6. Confirmation of registration — once the Deeds Office has processed the filing, the contract is reflected on the parties’ marriage documentation and will apply at any future dissolution.

Why the Contract Must Be Signed Before the Marriage

Section 2 of the Matrimonial Property Act requires the contract to be executed “in contemplation of marriage” — it is invalid if the parties are already married when they sign. Couples who marry without an ANC are married in community of property by default; they cannot simply sign an ANC later to change this. The only post-marriage route is a section 21 application to the High Court, which requires notice to creditors, a statement of the parties’ assets and liabilities, and a court finding that there is a sound reason for the change. The application is materially more involved than a pre-marital ANC, and courts do not grant it as a matter of course.

This timing rule is the single biggest reason that “we’ll get to it after the wedding” does not work. The pre-marital window is the only window in which the contract can be executed without a court application, and the practical effect of leaving it too late is to lock the couple into the default in-community regime from the date of the marriage onwards.

Why the Contract Must Be Registered at the Deeds Office

An ANC that is signed and attested but not registered at the Deeds Office is treated as if it does not exist for matrimonial property purposes — the marriage will be in community of property by default. The Deeds Office registration is the formal step that puts the world on notice of the parties’ chosen regime, and it is what allows third parties (banks, SARS, opposing parties in a future divorce) to verify the regime. The notary who attests the contract typically also handles lodgement; this is a service the firm’s admitted notaries provide as part of the engagement.

It is worth being clear on where the contract is filed, because it is sometimes assumed to be filed at the Department of Home Affairs, with the marriage officer, or at the magistrate’s court. It is not. The contract is lodged at the Deeds Office in the province where the marriage took place (or where the parties are domiciled). For Gauteng-based couples the registration runs through the Johannesburg or Pretoria Deeds Office depending on the district, and the Deeds Office processing time is the part of the timeline that varies most. The firm’s admitted notaries on staff — Natasha van Deventer and Amanda le Roux at the Bedfordview branch, and Chanté Marais at the Pretoria branch — handle the attestation and Deeds Office lodgement as part of the same engagement, so the file does not have to be handed off to a third-party notary between the attorney and the Deeds Office.

The Accrual Calculation, Briefly

At dissolution (death or divorce), each spouse’s estate is valued as at the date of the marriage (the “commencement value”) and as at the date of dissolution (the “dissolution value”). The difference for each spouse is that spouse’s accrual. The spouse with the smaller accrual has a claim against the other for half the difference between the two accruals.

The default exclusions in section 6 of the Act cover inheritances, donations, and personal-injury damages received during the marriage — these do not count toward the recipient spouse’s accrual unless the ANC says otherwise. The ANC can extend or contract these defaults (e.g. capture inheritances into the accrual pool, or exclude additional categories), and the firm’s role is to draft the contract so that the parties’ intentions on these points are clearly recorded.

What Can Be Tailored in the ANC

An ANC with the accrual system has standard clauses, but the tailoring is where most of the legal value lies. The areas the parties can shape are:

• Asset exclusions from the accrual — parties can extend the default exclusions (e.g. capture inheritances and donations into the accrual pool) or add their own categories (e.g. exclude a specific pre-marital business interest).
• Commencement value of the estates — the Act deems the commencement value to be the net value of each spouse’s estate at the date of the marriage, but the parties can agree a specific deemed value in the ANC, which is useful where a spouse owns a pre-marital business that is hard to value.
• Order of accrual vs. other claims — the Act gives the accrual claim priority over maintenance and certain other claims, but the parties can agree to vary this in the ANC, and the court has discretion to vary the default 50/50 split on fairness grounds.
• Treatment of a spouse who leaves the workforce to care for children — this is one of the typical scenarios where the court’s discretion to vary the accrual share is engaged, and it is worth flagging explicitly so clients understand the risk that the default 50/50 is not always the outcome.

The drafting decisions on these points are usually the most consequential part of the contract. A well-drafted ANC records the parties’ intentions clearly enough to be enforced as written; a poorly-drafted one often produces the opposite of what the parties thought they had agreed.

Why Use a Firm Rather Than an Online Template

An ANC with the accrual system has standard clauses, but the decisions about what to exclude, what to include, and how to handle specific pre-marital assets or business interests are not standard — they need a tailored draft and advice on consequences. The notary step is the same regardless of who drafts the contract, but the drafting step is where errors are most often made and most expensive to fix later. Burger Huyser’s Family Law team — including Denisha Padachey, who is repeatedly named in client reviews for ANC work — drafts, attests, and registers the contract as a single engagement, with admitted notaries on staff at the Bedfordview and Pretoria branches, so the file does not pass through a third party between the attorney and the Deeds Office.

The firm’s admitted notaries on staff handle the full sequence — drafting, advice on tailoring, attestation, and Deeds Office lodgement. The engagement does not hand off to a third-party notary in the middle, and the file is run by attorneys who are members of the Gauteng Family Law Forum and the Pretoria Attorneys Association, which keeps the team current on the evolving case law around judicial discretion to vary ANC terms.

Frequently Asked Questions

How much does an antenuptial contract with accrual cost in South Africa?

Niche online services advertise rates from around R1,950 all-inclusive for a standardised execution and registration. A full-service law-firm engagement — drafting, tailored advice on accrual exclusions and the treatment of pre-marital assets, notary execution, and Deeds Office registration — costs more, reflecting the time spent on the parties’ specific circumstances. Burger Huyser Attorneys quotes on a per-file basis after an initial consultation; book through the head office (Linden, Randburg) on 011 888 0246 or via the Bedfordview branch (011 201 7190) or Pretoria branch (012 471 5700) depending on which notary is most convenient.

Can we sign an antenuptial contract after we are already married?

No — section 2 of the Matrimonial Property Act 88 of 1984 requires the contract to be executed in contemplation of marriage, which means before the marriage takes place. Couples who marry without an ANC are married in community of property by default. The only post-marriage route is a High Court application under section 21 of the Act, which requires notice to creditors, a full disclosure of assets and liabilities, and a court finding that there is a sound reason for the change. The application is materially more involved than a pre-marital ANC and is not granted as a matter of course.

Do both parties need to see the same notary?

Yes — both parties must sign the ANC in the presence of the same notary public, who then attests the contract. A single notary with the requisite formal qualifications can handle both signatures. After attestation, the notary typically handles lodgement at the Deeds Office in the province where the marriage takes place (or where the parties are domiciled).

What happens if the antenuptial contract is not registered at the Deeds Office?

An ANC that is signed and attested but not registered at the Deeds Office within the prescribed window after the marriage is treated as if the parties are married in community of property — they share a joint estate, and each spouse’s creditors can reach the other spouse’s share. The Deeds Office registration is what gives the contract force as the matrimonial property regime; it is the formal step that makes the contract binding against the world, not just between the parties.

How is the accrual calculated when the marriage ends?

At dissolution (death or divorce), each spouse’s estate is valued as at the date of the marriage and as at the date of dissolution. The difference for each spouse is that spouse’s accrual. The spouse whose accrual is smaller (including a spouse with a zero or negative accrual, which is treated as zero) has a claim against the other for half the difference between the two accruals. The default exclusions in the Act (inheritances, donations, and personal-injury damages received during the marriage) are not counted toward the recipient’s accrual unless the ANC says otherwise.

Can we exclude certain assets from the accrual calculation?

Yes — the parties can extend or contract the default exclusions in the ANC. The Act excludes inheritances, donations, and personal-injury damages from the accrual by default; the ANC can capture these back into the accrual pool, or add other categories of asset (for example a pre-marital business interest) to the exclusion list. The drafting decisions on these points are usually the most consequential part of the contract, and they are worth working through carefully with the attorney before execution.

Is the accrual system the same as a prenuptial agreement in the American sense?

No — “prenup” in American usage typically refers to a contract that sets out how the couple’s property will be divided on divorce, often overriding the default rules. South African antenuptial contracts do something different: they select the matrimonial property regime itself (in community, out of community without accrual, or out of community with accrual) under the Matrimonial Property Act. The “with accrual” variant then produces its own built-in sharing mechanism on dissolution; it does not require the parties to negotiate a bespoke division. The end result is a more formulaic regime than a typical American prenup, with less room for bespoke terms and more reliance on the Act’s default rules.

Where is the Burger Huyser head office, and do I have to attend there?
