Divorce is rarely a single event. In South Africa, it is the legal end of a marriage that has usually broken down over months or years of stress, disappointment, and unmet expectations. Understanding the most common reasons couples divorce can help you make sense of your own situation and approach the legal process with realistic expectations.
It is important to understand one feature of South African family law from the outset. The Divorce Act 70 of 1979 recognises only one ground for divorce: the irretrievable breakdown of the marriage. The factual reasons people often describe as the “cause” of their divorce, such as infidelity, financial conflict, or poor communication, are not separate legal grounds. They are the evidence that the marriage relationship has broken down beyond repair.
At Otrebski Attorneys, our Family Law department helps clients across Sandton and the wider Gauteng region work through this distinction every day. Below we set out the relationship and factual reasons most commonly raised in South African divorces, and how section 4 of the Divorce Act ties them back to the single ground of irretrievable breakdown. Divorce laws in South Africa are designed to protect the rights of both parties while promoting fair settlements. Understanding the nuances of these laws can significantly impact the outcomes of divorce proceedings. It is essential for individuals to seek legal advice to navigate the complexities and ensure that they are adequately represented.
The Single Legal Ground: Irretrievable Breakdown
Section 4 of the Divorce Act 70 of 1979 provides that a court may grant a decree of divorce on the ground that the marriage relationship between the parties has broken down irretrievably. There is no menu of separate grounds to choose from. A plaintiff must satisfy the court that the marriage has reached the point where no reasonable prospect exists of the parties restoring a normal marriage relationship.
Section 4(2) sets out the indicators a court may treat as evidence of irretrievable breakdown. These include the parties not having lived together as husband and wife for a continuous period of at least one year, the defendant having committed adultery, and the defendant having treated the plaintiff in a way that makes continued cohabitation dangerous or intolerable. None of these factors is automatically a “ground” on its own. They are the facts from which the court infers that the marriage has broken down.
With that legal framework in mind, the following sections describe the most common relationship reasons South African couples give for ending their marriages. Each of these ultimately feeds back into the single enquiry under section 4.
Breakdown in Communication
Poor communication is one of the most frequently cited reasons for divorce. Couples stop talking meaningfully about finances, parenting, intimacy, or plans for the future. Small resentments accumulate, misunderstandings multiply, and emotional distance follows. Over time, the silence itself becomes the problem.
Communication breakdown rarely appears in the summons as a standalone allegation, but it is often the underlying cause of the parties living separate lives under one roof. Where this has continued for a year or more, it supports the section 4(2) indicator of non-cohabitation.
Infidelity and Loss of Trust
Adultery is expressly named in section 4(2) of the Divorce Act. An extramarital relationship strikes at the trust and exclusivity on which a marriage is built, and many couples find that trust cannot be rebuilt even with professional help. Infidelity is also frequently bound up with other problems such as deception, financial secrecy, or emotional withdrawal.
While adultery no longer gives rise to a delictual claim against a third party in South African law, following the Supreme Court of Appeal’s decision in RH v DE, it remains highly relevant as evidence of irretrievable breakdown. It can also influence the court’s view of the surrounding factual matrix when maintenance and patrimonial issues are considered.
Financial Stress and Money Conflict
Disagreements about money are a constant theme in divorce statistics worldwide, and South Africa is no different. Conflict over debt, unequal earning capacity, undisclosed spending, gambling, and the cost of supporting extended families can erode a marriage over years. The pressures of a constrained economy, retrenchment, or one spouse carrying the full household burden often intensify the strain. Divorce settlement costs in South Africa can vary widely depending on the complexity of the case and the assets involved. It is essential for both parties to understand their financial obligations and entitlements to reach a fair agreement. Seeking professional legal advice can help navigate these costs and prevent disputes from escalating further.
Money conflict is not a separate ground for divorce, but it frequently produces the hostility and separation that satisfy the irretrievable breakdown enquiry. It also drives contested disputes over the division of the joint estate, especially in marriages in community of property, and over spousal maintenance.
Substance Abuse and Addiction
Addiction to alcohol, drugs, or gambling damages marriages in ways that are both visible and hidden. The non-dependent spouse often bears the financial, emotional, and parenting consequences. Trust erodes, safety is threatened, and the dependent partner may refuse help. Children in the home are particularly affected.
Where addiction leads to behaviour that makes continued cohabitation dangerous or intolerable, it engages the section 4(2) indicator of intolerable treatment. Our attorneys also work closely with clients to ensure that protection orders and parenting arrangements address the welfare of any children before the divorce is finalised.
Domestic Abuse and Intolerable Treatment
Physical, emotional, verbal, financial, and sexual abuse are serious realities in many marriages that end in divorce. The Domestic Violence Act 116 of 1998 provides protection orders that operate independently of, and alongside, divorce proceedings. Abuse that makes continued cohabitation dangerous or intolerable is the third statutory indicator of irretrievable breakdown under section 4(2).
If safety is an immediate concern, a protection order should be sought first. The Family Law team at Otrebski Attorneys can advise on how protection orders, divorce summons, and interim care arrangements for children fit together.
Growing Apart and Incompatible Values
Many divorces are not the product of a single crisis. Couples simply grow in different directions. Religious practice, parenting philosophy, career ambition, lifestyle, or values around extended family can drift apart over a decade or two. What once felt like a shared life becomes a parallel one.
This gradual drifting apart is sometimes described colloquially as “irreconcilable differences”. In South African law it is captured within the single ground of irretrievable breakdown. The longer the parties have lived separate lives, the easier it becomes to demonstrate that the marriage has broken down.
Parenting Disputes and Step-Family Pressures
Different approaches to discipline, religion, education, and the involvement of extended family can produce sustained conflict. Blended families face added complexity, with stepparent roles, maintenance obligations towards children from previous relationships, and loyalty conflicts on the part of children.
When parenting disputes become entrenched, the effect on both the marriage and the children can be serious. In the divorce itself, the Children’s Act 38 of 2005 and the principle of the best interests of the child govern care, contact, guardianship, and maintenance.
Extended Separation
Work migration, study abroad, and the realities of a regional economy mean that some South African spouses live apart for long stretches. Where the parties have not cohabited as husband and wife for a continuous period of at least one year, section 4(2) treats that as evidence of irretrievable breakdown.
Many couples in this position assume that separation alone ends the marriage. It does not. A formal divorce is still required to divide the estate, deal with maintenance, and record parenting arrangements, especially where the marriage was in community of property.
Unrealistic Expectations and Unmet Needs
Some marriages end without a dramatic event. One or both partners enter the relationship with expectations about roles, intimacy, finances, or lifestyle that are never reconciled. Over years these unmet needs produce quiet disappointment, then emotional withdrawal, and finally indifference.
Indifference of this kind is often the clearest sign that the marriage has broken down irretrievably. The court is not concerned with allocating moral blame for unmet expectations, but with whether a normal marriage relationship can realistically be restored.
In-Law and Family Interference
In many South African families the boundary between the marital household and the extended family is fluid. Cultural expectations, financial dependence, and shared living arrangements can mean that in-laws exert real influence over day-to-day decisions. Where that interference is sustained and resented, it places enormous pressure on the marriage.
Family interference is not itself a ground for divorce, but it often contributes to the communication breakdown, separation, or intolerable treatment that does satisfy section 4. It is also a common source of conflict over the parenting and religious upbringing of children.
Divorce in Numbers: The Trend Since 2022
Divorces granted by South African courts each year, from Statistics South Africa’s official Marriages and Divorces releases. The direction is unmistakable: grants have risen every year since 2021.
- In 2024, 57.2% of divorce actions were filed by wives, 33.0% by husbands.
- 55.7% of 2024 divorces involved children under 18.
- The largest share of divorcing couples (26.7% in 2024) had been married 5 to 9 years.
Source: Statistics South Africa, Marriages and Divorces releases (P0307), 2022 to 2024 data; the 2024 release was published in March 2026. Court grants lag filings, so annual totals shift slightly as late registrations are processed.
How These Reasons Reach the Court
In practice, a divorce summons combines the factual narrative with the statutory language. The plaintiff sets out what went wrong in the marriage and then alleges that, having regard to those facts, the marriage relationship has broken down irretrievably so that there is no reasonable prospect of restoring a normal marriage. Where appropriate, the particulars of claim will rely specifically on one or more of the section 4(2) indicators.
Uncontested divorces, where the parties have settled the patrimonial and parenting issues, can be finalised relatively quickly. Contested matters take longer and often turn on disputes over the division of assets, maintenance, and care of children rather than on the fact of the breakdown itself. Understanding the key differences in divorce types can help individuals navigate the process with greater clarity. For instance, mediation may be a suitable option for couples looking to reach an amicable resolution. In contrast, those facing contested divorces often benefit from professional legal counsel to advocate for their interests.

Frequently Asked Questions
What is the only ground for divorce in South Africa?
Under section 4 of the Divorce Act 70 of 1979, the only ground for divorce is that the marriage relationship between the parties has broken down irretrievably, meaning there is no reasonable prospect of restoring a normal marriage.
What are the section 4(2) indicators of irretrievable breakdown?
The Act lists three indicators: the parties not living together as husband and wife for at least one continuous year, the defendant committing adultery, and the defendant treating the plaintiff in a way that makes continued cohabitation dangerous or intolerable.
Is adultery a separate ground for divorce?
No. Adultery is one of the section 4(2) factual indicators that support the single ground of irretrievable breakdown. It is also no longer a delictual claim against a third party following the SCA decision in RH v DE.
How long does a divorce take?
An uncontested divorce with a signed settlement agreement can be finalised in a few months. Contested divorces, especially those involving children or complex estates, frequently take a year or longer.
Do the reasons for divorce affect asset division?
Generally no. The division of assets depends primarily on the marital property regime. The factual reasons for the breakdown are usually relevant to the section 4 enquiry rather than to the patrimonial consequences.
