How to Calculate Child Support in South Africa: A Complete Guide

Last updated: October 25, 2026

What the Maintenance Act Requires of Both Parents

Child support in South Africa is governed by the Maintenance Act 99 of 1998. The Act starts from one non-negotiable principle: every child has a legal right to reasonable maintenance from both parents, and a parent has a duty to support a child in proportion to that parent’s means. Maintenance is not a favour and it is not something a parent can trade away in a divorce settlement. It is an obligation that follows the child, not the relationship between the adults.

Maintenance is defined broadly in the Act. It covers food, clothing, accommodation, medical care, and education, and it extends beyond the bare minimum needed to survive. A child is entitled to maintenance that reflects the standard of living the parents could reasonably afford to provide. This means the figure is not a fixed national tariff; it is worked out case by case, based on what the child actually needs and what each parent can actually pay.

The duty falls on both parents, and it also falls on other people who are legally liable to support the child in some circumstances, such as a step-parent in certain situations. For the purposes of calculating an amount, however, the court starts with the biological or adoptive parents and their respective means.

How the Maintenance Court Process Works

A maintenance matter begins with an application at the maintenance court, which is part of the Magistrates’ Court. There is a maintenance court attached to every magisterial district, and the service is free. You do not need an attorney to apply, although legal representation is permitted. The applicant completes a simple form, and a maintenance officer is appointed to the matter.

The maintenance officer does not sit as a judge. The officer’s first job is to investigate the matter and to try to settle it by agreement between the parties. The officer has the power to call both parents in, to request documents such as payslips, bank statements and proof of expenses, and to conduct an inquiry into each parent’s financial position. If the parents reach an agreement, the officer can record it as a consent order, which has the same legal force as an order made after a full inquiry.

If no agreement is reached, the matter is referred to the magistrate’s court for a formal enquiry, where both parents give evidence under oath and the court makes a finding. In 2026 the Department of Justice and Constitutional Development has continued rolling out its online maintenance portal and electronic filing channels, which let applicants lodge and track maintenance applications without repeatedly queuing at the court. The portal does not change the underlying law, but it has made the process more accessible, especially for parents who live far from the relevant court.

The Role of the Maintenance Officer and the Maintenance Intervention Officer

The maintenance officer is the first point of contact and the person who does most of the investigative work. The officer’s role is to establish the facts: who earns what, what the child’s reasonable needs are, and whether either parent is hiding income or assets. Officers can subpoena employers, banks and SARS for information, which makes it harder for a parent to simply refuse to disclose their finances.

Where a parent cannot be traced, or where the investigation stalls, the court can call on a maintenance investigator. The brief refers to this role as the Maintenance Intervention Officer, and in practice this is the investigating function that helps locate a defaulting parent, establish their true means, and gather the evidence needed to enforce or vary an order. The intervention officer’s contribution matters most in the harder cases, where a parent has changed jobs, moved address, or is working informally to avoid a paper trail.

Neither the maintenance officer nor the intervention officer decides the final amount on their own in a contested matter. They prepare the ground. The decision belongs to the court, guided by the officer’s investigation and by the evidence the parents put forward.

The Means Test: Income, Expenses and Dependants

The heart of any maintenance calculation is the means test. The court looks at three things for each parent: income, necessary expenses, and the number of dependants each parent already supports. Income includes salary, wages, commission, bonuses, rental income, and business profits. It is the parent’s net disposable income, after tax, UIF, and other compulsory deductions, that matters most, because that is the money actually available to spend on the child.

Necessary expenses are the reasonable costs a parent must meet to live and work: accommodation, food, transport to work, utilities, and existing debt repayments. The court allows these before it works out how much is left over for maintenance, because a parent cannot pay maintenance out of money they need to survive and keep earning. Luxuries and discretionary spending are not given the same weight.

Dependants matter because the duty to support is spread across everyone a parent is legally obliged to maintain. A parent who already supports other children, or an elderly parent, has a reduced capacity to pay, and the court takes that into account. The test is always one of balance: what is left after necessary expenses and existing duties, and how much of that can fairly go to the child.

The Proportional-Contribution Principle

South African maintenance law does not split the cost of a child evenly. It splits it proportionally to each parent’s means. This is the proportional-contribution principle, and it is the single most important idea to understand when you calculate a figure. A parent who earns twice as much as the other parent should carry roughly twice as much of the child’s maintenance burden.

The principle applies even where one parent has primary care of the child. A parent who has the child living with them is already contributing directly every day, through housing, food, transport and time. The court recognises this in-kind contribution, so it is usually the non-resident parent who is ordered to pay a monthly cash amount, and that amount is set with the resident parent’s in-kind contribution taken into account.

The result is that the paying parent’s cash contribution is calculated as their share of the child’s total reasonable needs, measured against the combined means of both parents. It is a share of the cost, not an arbitrary round number, and that is why two families with children of the same age can end up with very different maintenance orders.

How to Calculate Maintenance from Net Income

The calculation follows a clear sequence. First, establish the child’s total reasonable monthly needs: food, clothing, education, medical aid or medical costs, and a fair share of accommodation and household costs. Second, establish each parent’s net monthly income. Third, add the two net incomes together to get the combined means. Fourth, express each parent’s income as a percentage of the combined figure. Fifth, apply the non-resident parent’s percentage to the child’s total needs.

Take a realistic example. A mother has primary care of two children. Their reasonable combined monthly needs are R6,000, or R3,000 per child. The mother’s net income is R12,000 and the father’s is R23,000, giving a combined net income of R35,000. The father’s share of the combined means is R23,000 divided by R35,000, which is 65.7%. The father’s cash contribution is therefore 65.7% of R6,000, which comes to about R3,943 per month. The mother’s 34.3% share is treated as being met through her day-to-day care and the home she provides.

The figure is not set in stone. The court can adjust it for the mother’s own share of the children’s needs, for which parent pays school fees directly, and for medical aid contributions already deducted from one parent’s salary. The important point is the method: needs first, then means, then a proportional split.

When a Parent Is Unemployed or Self-Employed

Unemployment does not automatically end the duty to support a child, but it changes the calculation. A parent who is genuinely unemployed and has no income cannot be ordered to pay money they do not have, but the court will look carefully at whether the unemployment is real and whether there is other capacity, such as assets, investments, or a new informal income stream. A parent who quits a job to avoid maintenance will find the court unsympathetic.

Self-employed parents present a different challenge, because their income is not neatly reflected on a payslip. The court and the maintenance officer will look at bank statements, invoices, tax returns and business turnover to establish true earnings, and they are alert to parents who under-declare. The test is the parent’s actual means, not the figure they choose to report.

In both cases the order can be structured flexibly. It can be low now and reviewed later, or it can be linked to a percentage of income that rises as the parent’s situation improves. The system is designed to keep the child supported through the parent’s bad patch while remaining fair to a parent who simply cannot pay more.

Maintenance Order vs a Private Agreement

Parents are free to agree on child support between themselves, and a private agreement can work well when the relationship is cooperative and both sides keep their word. But a private agreement has a real weakness: it is not enforceable the way a court order is. If one parent stops paying, the other cannot take the private agreement to a sheriff or a garnishee order without first going through the court process anyway.

A maintenance order made by the court, by contrast, is a legal instrument that the state will enforce on request. A consent order, where the parents agree but have the agreement recorded by the maintenance officer, gives you the best of both worlds: it is based on your own arrangement, but it carries the full force of a court order and can be enforced if the payer defaults.

That is why the safer route, even for parents who get on well, is to have the agreement made an order of court. It protects the child against a change of heart later, and it removes the need to start from scratch if the arrangement breaks down. If the parents are separating or divorcing, a divorce settlement agreement template records the maintenance terms, the contact schedule and the parenting arrangements in one document that a court can make an order of court.

Enforcing an Order: Warrants and Garnishee Orders

When a parent fails to pay in terms of a maintenance order, the person owed maintenance can return to the maintenance court and ask for enforcement. The remedies available are powerful. The court can issue a warrant of execution against the defaulter’s movable property, which the sheriff can attach and sell to recover the arrears. It can also make a garnishee order, formally an emoluments attachment order, which deducts the maintenance directly from the defaulter’s salary before it reaches their bank account.

For a parent who has no property and no regular salary, the court has further options, including suspending a driver’s or other licence in certain circumstances and referring the matter for prosecution, because failing to pay maintenance in terms of an order is a criminal offence. The arrears themselves never fall away: maintenance debt survives and can be pursued even years later.

These enforcement tools are what give a maintenance order its teeth, and they are also the strongest argument for getting a private arrangement made an order of court in the first place. An agreement on a piece of paper cannot trigger a garnishee order; a court order can.

Varying an Order, Common Mistakes and Your Questions Answered

Maintenance is not frozen in time. Either parent can apply to the maintenance court to vary an order when circumstances change, whether that is a pay rise, a job loss, a new child, a serious illness, or a change in the child’s needs. The same means test applies, but now against the new facts, and the court will adjust the amount up or down accordingly. Varying an order is a normal part of the system, not an admission that the original order was wrong.

Common mistakes are worth flagging because they cost families money and time. The first is confusing a private agreement with a court order and finding out too late that it cannot be enforced. The second is guessing at the other parent’s income instead of asking the maintenance officer to investigate it. The third is failing to keep receipts and records of what you actually spend on the child, which are the very evidence the means test relies on. The fourth is stopping payments because the other parent is difficult; maintenance is for the child, and withholding it is never a lawful bargaining tool.

Is there a fixed minimum amount of child support in South Africa?

No. South Africa does not prescribe a fixed rand amount or a percentage tariff for child support. The figure is always the result of the means test applied to your specific circumstances, which is why two families can receive very different orders for children of the same age.

Can I claim maintenance if the other parent has moved abroad?

Yes, in principle. South Africa has reciprocal enforcement arrangements with several countries, and the maintenance court can assist with tracing and with enforcing an order across borders. It is more complex and slower than a domestic claim, but a parent abroad does not escape the duty by leaving the country.

What happens if I cannot afford a lawyer?

You do not need a lawyer to apply for maintenance. The maintenance court process is designed to be used by people representing themselves, and the maintenance officer assists with the paperwork and the investigation. Legal aid may also be available if you qualify.

Once you have a clear picture of the child’s monthly needs, the next practical step is to see how those costs fit into the rest of the household’s budget.
