Married Under Customary Law? Why Your Post-Marriage ANC Might Be Invalid (2026 Update)

If you followed the beautiful tradition of a customary marriage: often starting with the payment of lobola: and followed it up months or even years later with a civil ceremony (your "white wedding"), you might be sitting on a legal time bomb.

For many South African couples, the civil ceremony is seen as the "official" start of their legal marriage. It is common practice to sign an Antenuptial Contract (ANC) just days before the white wedding, believing this will protect your assets and ensure you are married "out of community of property."

However, a landmark 2026 ruling by the Constitutional Court in VVC v JRM and Others has sent a clear message: if you were already married under customary law when you signed that ANC, your contract is likely invalid.

This means you might be married in community of property without even knowing it, exposing your assets and your future to significant risks. At TRM Legal and Tax Advisory Services, we want to help you navigate this complex landscape and ensure your marriage is built on a solid legal foundation.

Understand Your Marriage Timeline

In the eyes of South African law, a customary marriage is not a "trial" or a "preliminary" step; it is a full, legally binding marriage. The moment the essential requirements of a customary marriage are met: usually including the negotiation and payment of lobola and the "handing over" of the bride: you are legally married.

The 2026 Constitutional Court ruling confirms that when you later have a civil ceremony, you are not entering into a new marriage. Instead, you are continuing the same marriage under a different legal framework. The court views this as one continuous relationship.

For example: If you concluded your lobola negotiations and the traditional ceremony took place in June 2024, but your white wedding only happened in December 2025, your legal marriage date is June 2024. If you signed an ANC in November 2025, that contract was signed after you were already married.

Recognize the Legal Trap

The danger lies in the default rules of the Recognition of Customary Marriages Act. Unless you have a valid Antenuptial Contract in place before the customary marriage begins, your marriage is automatically in community of property.

Many couples fall into a "trap" by thinking they can change this regime at the time of their civil ceremony. They sign an ANC, the marriage officer registers it, and they receive a marriage certificate. They believe they are protected.

The VVC v JRM and Others ruling clarifies that this "post-marriage" ANC is invalid. Because you were already married (under customary law), you cannot simply sign a contract to change your property regime. Once you are married, the law requires a much more formal process to change how your assets are handled.

Assess the Risks of an Invalid ANC

If your ANC is found to be invalid, the consequences can be life-altering. You are effectively transitioned back to the default state of being married in community of property. This affects several key areas:

1. Shared Liability for Debt: In a marriage in community of property, you are responsible for your spouse's debts. If your partner’s business fails or they take out a large loan, creditors can come after your assets, including your salary and savings.

2. Loss of Asset Control: You lose the ability to sell or mortgage major assets (like a house) without your spouse's written consent.

3. Divorce Complications: During a divorce, the "joint estate" is split 50/50. This includes assets you might have thought were your separate property, such as an inheritance or a business you started before the civil ceremony.

4. Estate Planning Issues: When one spouse passes away, the entire joint estate is frozen, which can cause immense financial strain for the surviving spouse.

To protect your legacy, it is vital to ensure your Estate Planning aligns with your actual marital regime.

Navigate the High Court Process (Section 21)

So, what do you do if you realized your ANC was signed too late? You cannot simply sign a new one. The only way to fix an invalid matrimonial property regime is through a Section 21 application to the High Court.

Section 21 of the Matrimonial Property Act allows couples to apply to the court to change their regime from "in community" to "out of community" of property. However, this is not an automatic right. You must prove to the court that:

• There are sound reasons for the change.

• Sufficient notice has been given to all your creditors.

• No other person will be prejudiced by the change.

This process requires a formal application, often involving an affidavit explaining why the ANC was not signed on time (e.g., a misunderstanding of the law regarding customary marriages) and a proposed "Postnuptial Contract" that the court will authorize you to sign.

Protect Your Property Ownership

One of the most common ways people discover their ANC is invalid is when they try to buy or sell a house. A conveyancing attorney will often spot that the lobola date preceded the ANC date, which halts the transaction.

If you are currently looking at property, it is essential to have your marital status verified. At TRM, our Property Law experts can help you determine if your current regime will impact your ability to register a bond or transfer a title deed.

For instance: If you buy a house today thinking you are married out of community of property, but your 2023 customary marriage makes you "in community," your spouse technically owns half of that house, and their creditors could potentially attach it.

Take Action: Your Customary Marriage Checklist

If you are worried about your marital status, take these proactive steps today:

1. Find Your Lobola Letter: Check the date on your initial agreement. This is likely the start date of your marriage.

2. Check Your ANC Date: Look at the date your Antenuptial Contract was signed by the Notary Public.

3. Compare the Dates: If the ANC date is after the lobola date, your contract is at risk of being declared invalid under the VVC v JRM ruling.

4. Gather Your Creditors List: If you need a Section 21 application, you will need a clear list of all your debts (credit cards, car loans, etc.).

5. Consult an Expert: Don't wait for a divorce or a death to find out your paperwork is wrong.
