ANC With Accrual vs Without (2026) | Which Prenup Should You Choose?

The accrual decision is the hinge point in many antenuptial contracts. It decides whether spouses keep separate estates but share growth, or whether each spouse keeps both their estate and its growth separate.

In South Africa, people often ask this as “prenup with accrual or without accrual?” The formal document is an antenuptial contract, also called an ANC. The practical question is whether the ANC should include the accrual system or expressly exclude it.

ANC with accrual vs without accrual South Africa

Quick answer

With accrual usually means each spouse keeps a separate estate during the marriage, but the growth in the spouses’ estates is shared when the marriage ends by divorce or death.

Without accrual usually means each spouse keeps a separate estate and there is no sharing of growth through the accrual system.

If your antenuptial contract excludes community of property but does not expressly exclude accrual, the accrual system applies. This choice should be made clearly before the ANC is signed.

ANC with accrual vs without accrual: comparison

Choice	Plain-English meaning	Often suitable where	Main risk
With accrual	Separate estates during marriage, with sharing of growth when the marriage ends.	Couples want protection for separate estates but a fair sharing of what is built during the marriage.	Commencement values, exclusions and proof of asset growth must be handled properly.
Without accrual	Separate estates and no sharing of growth through the accrual system.	Second marriages, business risk, major wealth differences, family assets or estate-planning concerns.	It can produce a harsh result if one spouse sacrifices earning capacity or contributes in non-financial ways.

When accrual may make sense

An ANC with accrual is often the balanced option. It can protect what each spouse brings into the marriage while still recognising that spouses may build wealth together over time.

Accrual may suit couples who want:

separate estates during the marriage;
protection from each other’s premarital debt exposure;
fair sharing of growth built during the marriage;
a less harsh result than complete separation.

The important details are commencement values, exclusions, inheritances, donations, business interests and proof. If these are vague, the accrual calculation can become a dispute later.

When no accrual may make sense

An ANC without accrual may suit couples who need stronger financial separation. It can be appropriate where there is business risk, significant premarital wealth, second marriages, suretyships, family trusts, or assets intended for children from a prior relationship.

But “without accrual” should not be chosen casually. It is not just a legal phrase. It can affect fairness, expectations and financial security if the marriage ends.

Examples

Young professionals building together

Accrual may be appropriate where both spouses want separate estates but also want to share growth built during the marriage.

Business owner with debt exposure

Without accrual may need to be considered where one spouse has business risk, suretyships or creditor exposure that should not pull the other spouse into financial uncertainty.

Second marriage with children from a prior relationship

Without accrual may be considered where each spouse wants to preserve assets for children or keep family wealth separate. Estate planning advice may also be needed.

What should be recorded before signing?

whether accrual is included or expressly excluded;
the commencement value of each estate where accrual applies;
which assets, if any, are excluded from accrual;
whether inheritances, donations, business interests or trust-related assets need special treatment;
how the contract will be signed before the notary and registered.

FAQ: ANC with accrual vs without accrual

Is an ANC with accrual better than without accrual?

Not always. Accrual is often balanced, but without accrual can be appropriate for business risk, second marriages, major wealth differences or specific estate-planning concerns.

What happens if accrual is not excluded?

If spouses marry out of community of property under an antenuptial contract and accrual is not expressly excluded, the accrual system applies.

What is the main risk with accrual?

The main risk is poor proof. Commencement values, exclusions and asset growth must be recorded properly, otherwise the calculation can become disputed later.

What is the main risk without accrual?

The main risk is unfairness. Without accrual can leave one spouse financially exposed if they contributed to the marriage in ways that did not build assets in their own name.

Can we change from with accrual to without accrual after marriage?

Changing the matrimonial property system after marriage is not a simple private update. It is a formal legal process and generally requires a court route.
