An antenuptial contract with accrual is often the balanced option. It allows each spouse to keep a separate estate during the marriage, while sharing the growth in their estates if the marriage ends by divorce or death.

This page explains when accrual may be suitable. If you are still deciding between with accrual and without accrual, start with the comparison guide: ANC with accrual vs without accrual.

What does “with accrual” mean?

When spouses marry out of community of property with accrual, they do not share one joint estate during the marriage. Each spouse keeps control of their own estate. At the end of the marriage, the growth in the spouses’ estates is compared and the accrual claim is calculated.

In plain English, accrual protects separate estates during the marriage but creates a fairness mechanism at the end.

When accrual may be the right choice

Accrual is often suitable where both spouses want independence during the marriage, but do not want a result that is unfair if one spouse earns less, takes time away from work, raises children, supports the household, or contributes in non-financial ways.

• One spouse may grow a career or business while the other carries more family responsibility.
• The couple wants protection from a joint estate, but not complete financial separation.
• Both spouses are comfortable sharing growth built during the marriage.
• There is no strong reason to exclude accrual completely.

When accrual may need careful drafting

Accrual is not a casual default. The antenuptial contract should be drafted carefully where either spouse has assets, business interests, expected inheritances, trust interests, debt exposure, or a major difference in starting wealth.

The most common problems are not caused by accrual itself. They are caused by vague drafting, poor records, unrealistic commencement values, unclear exclusions, and a failure to plan for valuation disputes.

What should be recorded before signing?

Before signing an ANC with accrual, couples should usually consider:

• each spouse’s commencement value;
• which assets, if any, should be excluded from accrual;
• how inheritances, donations, businesses and trust interests should be treated;
• whether there are debts, suretyships or business risks that need specific attention;
• what documents should be kept as proof.

Accrual compared with other marriage systems

Marriage with accrual sits between two alternatives. Marriage in community of property creates a joint estate. Marriage out of community of property without accrual creates stronger separation and no sharing of growth through the accrual system.

Can you change your ANC later?

An antenuptial contract is intended to be signed before marriage. Changing the matrimonial property system after marriage is not a simple late prenup. It is a formal legal process and generally requires a court route.

That is why it is better to understand the structure before signing, rather than trying to repair the position later.

When to get legal advice

Get legal advice before signing if there are businesses, properties, significant investments, inheritances, trusts, children from a previous relationship, creditor exposure, or a meaningful difference in wealth between the spouses.

FAQ: antenuptial contract with accrual

Is accrual the same as being married in community of property?

No. With accrual, each spouse has a separate estate during the marriage. The sharing mechanism applies to growth when the marriage ends.

Does accrual mean everything is split equally?

Not exactly. The accrual calculation compares the growth of the spouses’ estates. The result depends on commencement values, exclusions, debts and end values.

Can inheritances be excluded from accrual?

Inheritances and other assets can often be dealt with specifically, but the wording should be clear. Get advice before relying on a generic clause.

Is without accrual safer for business owners?

Sometimes, but not always. Business risk, suretyships, shareholding, valuation and fairness all matter. A business owner should get tailored advice before choosing.
