Maintenance for Children Over 18: When Does the Duty to Support End in SA?

One of the most common misconceptions in South African family law is that a parent's duty to maintain a child automatically ends when the child turns 18. In reality, the obligation continues for as long as the child remains dependent and unable to support themselves. This catches many parents off guard, so let's unpack exactly when the duty to support ends and what it means for your maintenance obligations.

Turning 18 Doesn't End Maintenance

Under South African common law, a parent's duty of support flows from need, not age. While a child reaches the age of majority at 18 in terms of the Children's Act 38 of 2005, this simply means the young person can now claim maintenance in their own name rather than through a parent or guardian. The financial obligation itself does not disappear.

The key legal test is whether the child is self-supporting. A dependent adult child who is studying full-time, has no income, and cannot reasonably maintain themselves is still entitled to reasonable support from both parents.

Students and Tertiary Education

The most common scenario involves a child who finishes matric and continues to university, a TVET college, or another form of tertiary study. Courts have consistently held that where a child is genuinely pursuing further education and cannot support themselves, both parents share a duty to contribute towards reasonable costs — including tuition, textbooks, accommodation, transport, and living expenses.

This is closely related to how school fees are handled in maintenance calculations, but tertiary costs can be significantly higher and often warrant careful budgeting. The contribution each parent makes is determined using the same principles that apply to younger children.

How Much Should Each Parent Pay?

The duty to support an adult dependent child is still shared between both parents according to their respective means. This is where the maintenance apportionment formula comes in — each parent contributes proportionally to their income after the child's reasonable needs are established.

For example, if the parents' combined income means one earns 60% and the other 40%, they would ordinarily split the child's reasonable expenses in that same ratio. Importantly, an adult child who has some part-time income may be expected to contribute towards their own upkeep, which reduces the parents' overall obligation.

When Does the Duty Actually End?

There is no fixed cut-off age. The duty ends when the child becomes self-supporting. This might happen when the child:

• Completes their studies and finds employment;
• Secures a full-time job that allows them to meet their own reasonable needs;
• Marries and is supported within that relationship; or
• Chooses not to study or work despite being able to do so (the duty may end here, as courts do not reward a child who unreasonably refuses to become independent).

A child who is disabled or chronically ill and cannot become self-supporting may be entitled to maintenance indefinitely, even well into adulthood.

Can an Adult Child Claim Maintenance Directly?

Yes. Once a child turns 18, they may approach the Maintenance Court in their own name to claim support from one or both parents. This can feel uncomfortable for families, but the process is the same as any other maintenance application. If you're unsure how the process works, our guide to the role of South Africa's Maintenance Court explains what to expect.

The adult child must still prove their reasonable needs and demonstrate that they are genuinely dependent. Bank statements, proof of registration at a tertiary institution, and a detailed monthly budget all strengthen the claim.

Stopping Payments the Right Way

A word of caution: do not simply stop paying maintenance the moment your child turns 18. If a court order is in place, you must apply to have it varied or discharged. Unilaterally halting payments can lead to enforcement action against you, including emoluments attachment orders and arrears claims. If you believe your child has become self-supporting, the correct route is to approach the court to adjust the maintenance order formally.

Preparing Your Budget

Whether you're a parent contributing towards an adult child's studies or a young adult claiming support, the foundation of a strong case is an accurate, itemised budget. The prescribed Form J101 remains the tool the court uses, and getting your figures right from the outset saves time and disputes.
