Marriage changes more than your relationship status. In South Africa, it creates binding legal consequences that affect property ownership, divorce proceedings, inheritance rights, maintenance obligations, and parental responsibilities. One of the most visible changes after marriage is often a surname, yet until recently, the law did not treat all spouses equally in this regard.
In September 2025, the Constitutional Court delivered a landmark ruling in Jordaan v Minister of Home Affairs. The judgement struck down gender-based surname restrictions that had shaped the administration of marriage for decades. For the first time, both heterosexual and same-sex couples now have complete freedom to decide which spouse’s surname to use after marriage or whether to combine them.
This development is more than administrative reform. It represents a meaningful shift in South African marriage law and strengthens equality within both civil marriages and civil unions. As family and divorce attorneys, we regularly advise clients on marriage registration, surname changes, divorce law, and estate planning. The Jordaan judgement has practical implications in all of these areas.
This article explains what the law looked like before the Constitutional Court intervened, why the surname framework was found unconstitutional, and how this decision will affect marriages and families across South Africa.
What the Law Looked Like Before the Jordaan Judgement
Before the 2025 ruling, surname changes after marriage were governed primarily by the Marriage Act and the administrative processes followed by the Department of Home Affairs. Although the Constitution guarantees equality, the practical implementation of surname registration did not fully reflect that principle.
Under the previous system, a wife could automatically adopt her husband’s surname upon marriage without following a separate name change procedure. A husband, however, did not enjoy the same automatic right. If he wished to take his wife’s surname, he was required to apply formally for a name change through a more complex administrative process.
This structure reflected traditional assumptions that positioned the husband’s surname as the default family identity. While many couples voluntarily followed this practice, the law itself created unequal treatment based purely on gender.
For same-sex couples married under the Civil Union Act, administrative inconsistencies sometimes created further confusion. The framework did not always clearly accommodate marriages that did not fit into traditional gender roles. This resulted in uncertainty and, in some cases, additional bureaucratic hurdles.
Although surname choice may seem symbolic, it forms part of a person’s legal identity. The fact that the law treated spouses differently based on gender raised serious constitutional concerns.
Why the Constitutional Court Intervened
In Jordaan v Minister of Home Affairs, the applicants challenged the constitutionality of the surname provisions and the administrative practices that flowed from them. The case centred on whether the existing system unfairly discriminated based on gender and whether it adequately respected equality in both heterosexual and same-sex marriages.
The Constitutional Court examined the matter through the lens of the Constitution, particularly the rights to equality, dignity, and freedom from unfair discrimination. The Court found that the surname framework imposed different legal consequences on spouses based solely on gender. It reinforced outdated patriarchal norms and failed to treat marriage as a partnership between equals.
The Court also recognised that administrative systems must reflect constitutional values. Even where legislation appears neutral on its face, if its application produces discriminatory outcomes, it cannot stand.
As a result, the Constitutional Court declared the gender-based surname restrictions unconstitutional. The Department of Home Affairs is now required to administer surname registration in a gender-neutral manner that treats all spouses equally.
What the 2025 judgement Means for Married Couples
Following the Jordaan judgement, couples entering into marriage in South Africa now have complete freedom to choose how they wish to structure their surnames. There is no longer any presumption that one spouse’s surname carries automatic priority.
Spouses may retain their existing surnames, adopt their partner’s surname, or combine both surnames in any order they choose. This freedom applies equally to civil marriages under the Marriage Act, customary marriages under the Recognition of Customary Marriages Act, and civil unions under the Civil Union Act.
The change reflects a broader constitutional principle that marriage is a legal partnership of equals. It confirms that neither spouse holds a superior legal position in determining family identity.
For couples, this offers clarity and flexibility. For family law practitioners and divorce attorneys, it creates a more consistent legal framework that aligns with constitutional equality.
The Impact on Civil Marriages in SA
For couples marrying under the Marriage Act, the impact is immediate and straightforward. The administrative system at Home Affairs must now treat both spouses equally when registering surnames. The automatic preference that previously existed has been removed.
This reform modernises civil marriage law in South Africa. It reinforces the idea that marriage is not structured around historical hierarchy but around mutual choice and equality.
In practical terms, this may also reduce disputes later in divorce proceedings. When surname decisions are made freely and equally at the outset, there is less room for misunderstanding or resentment during divorce.
The Impact on Customary Marriages
Customary marriages are fully recognised under the Recognition of Customary Marriages Act 120 of 1998. These marriages carry the same legal consequences as civil marriages in relation to property division, inheritance, and divorce.
Surname traditions may vary across communities, but official registration still takes place through state systems. The Jordaan judgement ensures that spouses in customary marriages are treated equally when recording their surnames.
This development aligns with earlier Constitutional Court decisions that strengthened women’s rights in customary marriages, including the landmark Gumede case, which confirmed equal property rights in certain customary marriages.
The broader trend within South African family law is clear. The courts continue to remove discriminatory practices and reinforce constitutional equality across all forms of marriage.
Strengthening LGBTQ+ Marriage Rights in SA
South Africa was the first country in Africa to legalise same-sex marriage through the Civil Union Act of 2006. While the legal recognition of same-sex marriage was a major milestone, administrative systems did not always reflect complete equality in practice.
Before the Jordaan judgement, surname registration procedures sometimes created confusion for same-sex couples. The framework had been built around gender-based assumptions that did not always translate smoothly into gender-neutral marriages.
The 2025 ruling resolves this issue. Same-sex spouses now enjoy the same freedom as heterosexual spouses to determine their shared surname or retain individual surnames.
This strengthens LGBTQ+ rights within South African marriage law and confirms that equality extends beyond the right to marry, encompassing every legal consequence of marriage.
Divorce Law & Surname Considerations
Divorce in South Africa is governed by the Divorce Act. During divorce proceedings, surname issues frequently arise. A spouse may wish to revert to a previous surname, retain the married surname for professional reasons, or address concerns relating to children’s surnames.
A clear and gender-neutral surname system at the time of marriage provides a stronger foundation when these issues arise during divorce. When the initial choice is made freely and equally, the legal position during divorce is more predictable.
At BA Attorneys, regularly assist clients with divorce applications, spousal maintenance claims, child custody disputes, and property division. Clear documentation and proper surname registration can prevent unnecessary complications during these processes.
Inheritance and Estate Planning Implications
Marriage has significant consequences under the Intestate Succession Act and other estate planning legislation. A surviving spouse is recognised as a legal heir, and accurate documentation is critical during estate administration.
Surname inconsistencies can delay the winding up of estates, complicate property transfers, and create uncertainty regarding pension benefits and insurance claims.
By ensuring that surname registration is clear and constitutionally compliant from the outset, the Jordaan judgement indirectly supports more efficient estate planning and administration.
Couples should review their wills, beneficiary nominations, and trust documents after marriage to ensure that their legal identity is accurately reflected.
The Broader Evolution of Family Law in SA
The Jordaan ruling forms part of a broader evolution in South African family law. Over the past two decades, the Constitutional Court has repeatedly affirmed that marriage law must reflect constitutional values.
The recognition of same-sex marriage, the strengthening of women’s property rights in customary marriages, and the reinforcement of gender-neutral maintenance principles all point toward a consistent direction.
The removal of gender-based surname restrictions continues that trajectory. It confirms that equality is not abstract. It must be visible in the daily administrative realities of marriage.
