Maintenance and the Duty of Support: Who Is Legally Liable for Your Child in SA?
One of the most common misunderstandings in South African maintenance matters is the belief that only one parent - usually the father, or the parent who doesn't have primary care - carries the financial burden of raising a child. In reality, our law is clear: both parents have a legal duty to support their children, regardless of whether they were ever married, still live together, or barely speak to one another.
Understanding exactly who is liable for a child's maintenance - and in what proportion - is the foundation of every fair maintenance arrangement. Let's break it down.
Where the Duty of Support Comes From
The duty to maintain a child flows from both the common law and the Children's Act 38 of 2005. Section 18 of the Act confirms that parental responsibilities and rights include the duty to contribute to the maintenance of the child. This duty exists automatically the moment a child is born - it is not something a court creates. A maintenance order simply gives that pre-existing duty a concrete monetary value and makes it enforceable.
Importantly, the duty of support is not conditional on contact or care. A parent who is denied contact with their child still has a duty to pay maintenance, and a parent who pays maintenance is still entitled to reasonable contact. The two are legally separate issues, and the maintenance court will not allow one to be used as a bargaining chip against the other.
Both Parents Contribute - According to Means
South African law does not simply split the cost of a child 50/50. Instead, each parent contributes in proportion to their respective means. This is the heart of the apportionment formula: the parent who earns more carries a larger share of the child's reasonable expenses, while the parent who earns less carries a smaller share.
For example, if the father earns R40,000 and the mother earns R20,000, their combined income is R60,000. The father's share of that income is roughly 67% and the mother's is 33%. If the child's reasonable monthly needs total R9,000, the father would contribute around R6,000 and the mother around R3,000 - each according to their ability. If you'd like to see this in detail, our guide on the maintenance apportionment formula works through the calculation step by step.
The parent who has primary care of the child is usually deemed to already contribute their share directly through the daily care, housing, food and supervision they provide. This is why the non-resident parent typically pays a monetary amount - it represents their proportional contribution to the shared household costs.
What Counts as "Means"?
When assessing ability to pay, the court looks well beyond a payslip. It considers salary, bonuses, commission, rental income, investments, business profits and even a demonstrable earning capacity where a parent is deliberately under-earning. Courts are alert to parents who understate their income - you can read more in our article on how SA courts assess ability to pay.
What Happens When a Parent Genuinely Can't Pay?
The duty of support is proportional, not absolute. If a parent is genuinely unemployed or earning very little, their share reduces accordingly - but it rarely disappears entirely. Courts expect every parent to make some contribution, even a modest one, because the duty to support attaches to the parent-child relationship itself.
Where a parent's income drops due to retrenchment or illness, the correct route is to apply to vary the existing order rather than simply stop paying. Unilaterally reducing payments leads to maintenance arrears that remain legally owing and enforceable.
When Others May Be Liable
If both parents are unable to support a child - for example, where parents are deceased or genuinely destitute - the duty of support can extend to other family members. Grandparents, in particular, may carry a duty of support in certain circumstances under the common law, based on their own means and the child's need.
Why This Matters for Your Application
Understanding that liability is shared and proportional changes how you approach your maintenance claim. Rather than demanding a fixed rand amount, you build a case around the child's reasonable needs and each parent's relative ability to pay. This is exactly what the Maintenance Act 99 of 1998 and the prescribed budget forms are designed to capture, always with the best interests of the child as the guiding principle.
