Maintenance and Domestic Partnerships: Support Duties for Unmarried Parents in SA

One of the most persistent myths in South African family law is that maintenance obligations only exist between people who were married. Many parents believe that because they never signed a marriage certificate, their financial duty to their child somehow depends on the nature of their relationship. This is completely incorrect - and it's a misunderstanding that can leave children without the support they are legally entitled to.

In South Africa, the duty to maintain a child flows from parenthood, not from marriage. Whether you were married, in a long-term cohabitation arrangement, or barely knew each other, both biological parents carry an equal legal responsibility to support their child according to their respective means.

The Legal Foundation

The Children's Act 38 of 2005 and the Maintenance Act 99 of 1998 make no distinction between children born inside or outside of marriage. Section 15 of the Maintenance Act confirms that the duty of parents to support their children is apportioned between them according to their respective means, regardless of marital status.

The old common law concept of a child being "illegitimate" has been abolished. Every child has the same rights to maintenance, care, and support. The best interests of the child remain paramount - a principle we explore in detail in our post on the golden thread running through SA maintenance law.

Establishing Paternity First

For unmarried parents, one practical hurdle can arise before maintenance is even discussed: proving paternity. Where a father disputes that he is the biological parent, the maintenance court may order scientific (DNA) testing. Under the Children's Act, an unmarried father who denies paternity but refuses to submit to testing may have an adverse inference drawn against him.

Where paternity is admitted or established, the maintenance enquiry proceeds exactly as it would for married or divorced parents. The court assesses each parent's income, expenses, and ability to contribute, then applies the apportionment formula.

How the Apportionment Works

The financial calculation for unmarried parents is identical to that for divorced parents. The court adds together both parents' incomes, works out each parent's proportional share, and then divides the child's reasonable monthly costs accordingly. If one parent earns 60% of the combined income, they generally carry 60% of the child's expenses.

If you're unfamiliar with how this is calculated, our guide to understanding the maintenance apportionment formula breaks it down step by step. The key point for unmarried parents is that being a father who was never married - or a mother who has always been the primary carer - does not change the mathematics. What matters is income and reasonable expenses.

Parental Rights and Responsibilities

Unmarried fathers should note that maintenance duties and parental rights are separate legal questions. Under section 21 of the Children's Act, an unmarried father acquires full parental responsibilities and rights if he was living with the mother in a permanent life partnership at the time of the child's birth, or if he contributes (or attempts to contribute) to the child's upbringing and maintenance.

Importantly, paying maintenance does not automatically buy contact rights, and being denied contact does not excuse a parent from paying maintenance. These are dealt with in separate proceedings. A parent who withholds maintenance to punish the other for denying access is misunderstanding the law - and the child suffers as a result.

Cohabitation and Shared Households

Where unmarried parents were living together and then separate, disputes often arise over which expenses were genuinely for the child versus the household. This is where distinguishing between child-specific and shared expenses becomes essential. A portion of rent, utilities, and groceries is legitimately allocated to the child, while items like the child's clothing or school fees are entirely child-specific.

Bringing a Claim

An unmarried parent seeking maintenance follows the same process as any other applicant. You lodge a Form A application at your nearest maintenance court, complete a Form J101 monthly budget, and attend a maintenance enquiry where a maintenance officer assesses the matter. Our step-by-step filing guide walks you through exactly what to expect.

Whether you were married for ten years or never lived together at all, the message from South African law is the same: your child has a right to be supported by both parents, and that right cannot be signed away or ignored because of the parents' relationship status.
