Do I Need an Antenuptial Contract?

A short answer for most modern couples: yes. The default marital regime in South Africa is in community of property — one shared estate, joint debts, spousal-consent rules. For most couples this is not the regime they would have chosen had they understood it. An antenuptial contract is how you choose differently.

Five reasons that usually decide it

1. Protection from each other’s debts

In community of property, you share all debts — including debts only one spouse incurred. If your spouse runs up a credit card, signs surety, or is sued, creditors can claim against the joint estate. An antenuptial contract creates two separate estates so each spouse is liable only for their own debts.

2. Independence in the day-to-day

Without a contract, neither spouse can sell immovable property, sign for major credit, or perform certain other acts without the other’s written consent. Couples in community of property frequently discover this only when their bank refuses to release funds. An antenuptial contract restores full contractual capacity to both spouses.

3. Protecting a business

If you own a business — or plan to start one — community of property creates real exposure. Bank surety, supplier credit, and operational loans typically require spousal consent. The business’s risk leaks back into your spouse’s assets. An antenuptial contract walls these off.

4. Protecting an inheritance

In community of property, an inheritance you receive falls into the joint estate unless the testator’s will specifically excludes it. With an antenuptial contract that includes the accrual system, inheritances are excluded automatically by operation of law — no special drafting needed in the will.

5. Fair sharing — without merging everything

The accrual system shares the growth built during the marriage without merging the assets you each had at the start. It is a fair compromise: independence and protection while you are married, equitable sharing when the marriage ends. Most couples find this is what they actually want.

When in community of property might still be the right call

A small number of couples deliberately choose to be in community of property — usually because:

• The symbolic meaning of complete sharing matters more than financial protection
• Neither spouse has, or expects to have, significant credit risk, business interests, or inherited assets
• They both want a single, simple shared estate without the calculations of accrual

If that describes you, you do not need an antenuptial contract — you simply marry without one. But this should be a deliberate, informed choice, not a default arrived at by failing to act.

Who almost always needs one

• Business owners — for the protection and the operational independence
• Second marriages — particularly where one or both spouses have children from earlier relationships
• Couples where one party brings significant existing wealth — whether earned, inherited, or trust-derived
• Couples where one party brings significant existing debt — to protect the other from absorption into the joint estate
• Couples marrying later in life — with built-up retirement plans, properties, and investments
