Weekly Legal Insight: No Duty to Maintain a Spouse’s Extramarital Child

A recent decision by the Gauteng High Court (Johannesburg) has clarified an important aspect of family law: a spouse cannot be compelled to financially support a child born outside the marriage.

In this matter, an unemployed husband sought interim relief during divorce proceedings, requesting maintenance of R4 500 per month for his child—who was conceived with another woman while he was still married. He also requested shared control over rental income generated from properties owned by his estranged wife.

Background

The parties were married in community of property in April 2022. At the time, the husband was 30 and the wife 46. No children were born from the marriage. However, in June 2025, the husband fathered a child with another woman.

Following this, the wife instituted divorce proceedings in September 2025, citing the extramarital affair and the birth of the child. Despite the breakdown of the marriage, the husband remained in the marital home and continued to rely on the wife for basic living expenses, including food.

The wife’s only income is derived from rental cottages situated on a property she owned prior to the marriage. Although the property has the potential to generate approximately R24 500 per month when fully occupied, it currently yields about R7 200.

The Husband’s Claim

The husband argued that he had previously used rental income to support the child and the child’s mother. He claimed that the wife’s decision to redirect rental payments into her personal account deprived him of the means to continue providing such support.

Based on this, he sought:

• Monthly maintenance for the child, and

• Shared control over the rental income.

The Court’s Ruling

The court dismissed both claims.

It held that:

• A spouse has no legal duty to maintain a child born outside the marriage unless they have expressly agreed to do so.

• The husband’s request for maintenance for the child falls outside the scope of Rule 43 proceedings, which are limited to interim relief such as spousal maintenance, contributions to legal costs, and arrangements concerning children of the marriage.

Regarding the rental income, the court found that:

• Disputes relating to the division or control of assets in a joint estate cannot be resolved under Rule 43.

• Such matters must be determined during the main divorce trial.

Key Takeaway

This judgment reinforces two important legal principles:

1. No automatic duty of support exists for a spouse in respect of a partner’s extramarital child.

   
   

2. Rule 43 applications are limited in scope and cannot be used to resolve complex financial disputes relating to the joint estate.

Final Thoughts

This case serves as a reminder that while marriage in community of property creates a shared estate, it does not extend personal obligations—such as child maintenance—to situations outside the marital relationship.
