Out of Community of Property With Accrual: How the Split Works

If your antenuptial contract includes the accrual system, you and your spouse have kept separate estates throughout the marriage — but at divorce, the growth of those estates gets equalized. That single sentence hides a fair amount of arithmetic, and getting it wrong by even a few thousand Rand in commencement values can shift a settlement significantly. Here's how the accrual system actually works, governed by Chapter I of the Matrimonial Property Act 88 of 1984.

The core idea

Each spouse declared a commencement value — what their estate was worth (or owed) when the marriage started. At divorce, you calculate how much each estate grew since then. The spouse with the smaller accrual has a personal claim against the other for half the difference between the two accruals. Your own assets stay yours; only the growth gets shared.

The formula

The statutory calculation is:

Accrual = Net End Value − (Commencement Value × CPI at Dissolution ÷ CPI at Commencement)

The CPI adjustment matters more than most people expect. It restates your commencement value in today's money using the weighted average Consumer Price Index published by Statistics South Africa, so a spouse who started the marriage with R200,000 in savings isn't shortchanged just because inflation ate into that number over 15 years. Getting stale or mismatched CPI figures is one of the most common accrual calculation errors.

If a spouse's liabilities exceeded their assets at the start of the marriage, their commencement value is legally deemed to be nil — you can't declare a "negative" starting point that boosts your claim.

What doesn't count toward accrual

Before applying the formula to your Net End Value, five categories must be excluded:

1. Inheritances and legacies received during the marriage
2. Donations from third parties, and donations between spouses (except those made in contemplation of death)
3. Any asset explicitly excluded in the registered ANC
4. Assets acquired by replacing an excluded inheritance, legacy, or donation
5. Damages awarded for personal injury (non-patrimonial damages)

Miss one of these and the calculation skews — usually in favor of whichever spouse benefits from the omission, which is exactly why disputes over commencement values and exclusions are so common in accrual divorces.

Pension interest counts toward accrual

Retirement savings aren't excluded from this calculation. Under Sections 7(7) and 7(8) of the Divorce Act, pension interest is included in the net end value of the member spouse's estate for accrual purposes — it isn't split separately the way it is in community of property marriages. This means your accrual figure is incomplete until you've correctly valued the pension component, and since September 2024's "Two-Pot" retirement reform, that valuation now spans three components (vested, savings, and retirement) rather than one.

Working the numbers without a spreadsheet error

Doing this by hand across multiple asset classes — property, investments, retirement funds, vehicles, business interests — is where most self-represented spouses lose confidence, and where disputes over valuation dates tend to start. The South Africa Divorce Financial Split & Asset Division Guide includes a dynamic accrual calculator with the CPI adjustment built in, so you input values once and the exclusions and inflation math happen automatically. See how the calculator works.

When this gets contested

Because accrual claims hinge on commencement values and exclusion evidence, disputes over "what was excluded" or "what was the estate really worth in year one" are common — particularly where a spouse suspects hidden assets or undisclosed corporate loan accounts. If that's your situation, this is one of the moments where a family law attorney earns their fee, especially for formal discovery and disclosure enforcement.

Whether you're negotiating an uncontested settlement or preparing figures for your attorney, having a clean accrual calculation before you sit down to negotiate puts you on equal footing. Get the full worksheet set and calculator here.
