Marriage is often spoken about in romantic, social and emotional terms, but at its core it is also a legal relationship with far-reaching financial consequences. While most couples understand that marriage affects how their assets are owned and divided, fewer fully appreciate that marriage also creates a reciprocal duty of support between spouses. In the South African context, this duty can have significant implications during the marriage, upon separation, during divorce proceedings, and in some cases even after the divorce has been finalised.
The duty of support is not merely a moral obligation to look after one another. It is a legal duty that arises from the marriage relationship itself (whether civil marriage, civil union, Muslim marriage, or customary marriage) and requires each spouse, according to their respective means, to contribute towards the reasonable needs of the other.
Further, this duty is reciprocal, meaning that it applies to both spouses, although how it plays out in practice will depend on the financial circumstances of each party. Importantly, the duty of support is not determined by gender, but rather by need on the one hand and ability to pay on the other. In a modern marriage, where both spouses may be earning an income, the obligation may be less visible. However, where one spouse is financially dependent on the other, has taken time out of the workforce to raise children, has supported the other spouse’s career, or has limited earning capacity due to age, health or family responsibilities, the duty of support becomes much more relevant.
During the marriage, spouses are expected to support one another in line with their joint standard of living and respective means. This includes contributing towards household expenses, accommodation, food, medical costs, clothing and other reasonable living expenses. Remember, the fact that one spouse may be the primary breadwinner does not mean that the other spouse has no financial value in the marriage. Many marriages are structured in a way where one spouse earns income while the other contributes through unpaid work, such as raising children, managing the household, caring for elderly parents or enabling the income-earning spouse to focus on their career. From a financial planning perspective, this is important because the non-earning or lower-earning spouse may become financially vulnerable if the relationship breaks down. The law recognises, at least to some extent, that financial dependence can be created within a marriage and that one spouse should not necessarily be left destitute simply because the marriage has come to an end.
It is also important to distinguish the duty of support from the matrimonial property regime. Whether a couple is married in community of property, out of community of property with accrual, or out of community of property without accrual, the duty of support exists during the marriage. While an antenuptial contract regulates the ownership and division of assets, it does not remove the legal responsibilities that arise from being married. This is where many couples misunderstand the position. A spouse who is married out of community of property without accrual may assume that, because their assets remain separate, they have no financial obligations towards the other spouse. This is not correct. Separate estates do not necessarily mean separate lives, and the duty of support remains a legal consequence of marriage.
The duty of support becomes particularly important when a marriage begins to break down – although keep in mind that separation does not automatically bring the duty to an end. In practice, this means that a spouse who has been financially dependent during the marriage may still require support while divorce proceedings are pending. South African law provides mechanisms for interim relief during divorce proceedings, including interim maintenance and a contribution towards legal costs in appropriate circumstances. This is especially important where one spouse controls most of the household income or financial resources, while the other spouse does not have the means to meet basic living expenses or fund legal representation. Divorce proceedings can be lengthy and expensive, and interim maintenance exists to ensure that the financially weaker spouse is not prejudiced simply because the divorce has not yet been finalised.
Once the divorce is granted, the position changes. The automatic reciprocal duty of support that exists during marriage comes to an end when the marriage ends. However, this does not mean that spousal maintenance can never be payable after divorce. In terms of section 7 of the Divorce Act, a court may make an order for spousal maintenance either by agreement between the parties or, in the absence of agreement, after considering a range of factors. These include the existing and prospective means of each party, their earning capacities, financial needs and obligations, their ages, the duration of the marriage, the standard of living prior to divorce, and any other factor the court considers relevant. In this regard, note that the court has wide discretion and the outcome will depend on the facts of each case.
Another key point that couples need to understand is that spousal maintenance after divorce is not automatic. South African courts generally recognise the principle of financial independence after divorce, although this principle must be balanced against fairness, need and the realities of the particular marriage. A short marriage between two financially independent professionals is unlikely to result in long-term maintenance. On the other hand, a long marriage in which one spouse gave up a career to raise children, relocate for the other spouse’s work, or manage the home may justify a different outcome, particularly if that spouse cannot realistically re-enter the workforce at the same level or within a short period of time. The courts may award rehabilitative maintenance, intended to assist a spouse for a limited period while they become self-supporting, or in certain circumstances longer-term maintenance where financial independence is not realistically achievable.
From a financial planning perspective, this area of law is important because divorce settlements are often negotiated under emotional pressure and without a full appreciation of future cash flow needs. A spouse may agree to waive maintenance in exchange for retaining the family home, only to discover later that the costs of running the property are unaffordable. Another may accept a capital settlement without considering whether it can generate sustainable income. Conversely, the spouse who is expected to pay maintenance must ensure that any agreement is affordable, measurable and aligned with their own financial obligations. Remember, maintenance is ultimately a cash flow issue, and cash flow needs to be modelled carefully before any agreement is signed.
It is equally important not to confuse spousal maintenance with child maintenance. Parents have a separate legal duty to support their children according to their means, and this duty exists independently of the marital relationship. A spouse cannot avoid contributing towards the reasonable needs of their children simply because the marriage has ended or because the children live primarily with the other parent. Child maintenance and spousal maintenance may be negotiated together as part of a divorce settlement, but they are legally and practically distinct.
Marriage creates a financial ecosystem, and both spouses need to understand how that ecosystem works. The duty of support is one of the legal principles that underpins this system, but it is often overlooked until the relationship is under strain. By then, misunderstandings around money, entitlement, fairness and independence can make an already difficult process even more fraught. For this reason, couples would be well advised to discuss their financial arrangements openly during the marriage, understand their matrimonial property regime, keep proper records, and seek professional advice before making decisions that could affect either spouse’s long-term financial security.
Ultimately, the duty of support is a reminder that marriage is not only a personal commitment, but also a legal and financial one. While the law does not guarantee lifelong maintenance after divorce, it does recognise that the choices made within a marriage can create real financial dependence. For South African couples, understanding this duty is essential — not because every marriage will end in divorce, but because every marriage carries financial consequences that deserve to be understood before they are tested.
Have a fabulous day.
