What is the Best Evidence for Family Court?

The best evidence for family court in South Africa is credible, relevant, and properly authenticated material that speaks directly to the facts in dispute, weighed through the lens of the child’s best interests under section 7 of the Children’s Act 38 of 2005 and section 28 of the Constitution. There is no single “strongest” item. The best evidence is the bundle that most clearly and lawfully proves the specific fact a court has to decide, whether that is care, contact, maintenance, or the division of assets.

In practice the strongest bundles combine first-hand documentary proof, sober expert opinion, and a clear narrative that maps each item back to a section 7 factor or to a definable financial fact. This page sets out the kinds of evidence that South African family courts actually weigh, the rules of admissibility that govern them, and how Otrebski Attorneys approaches the collection and presentation of evidence in the Family Law department at our Sandton office.

What “best evidence” means in a South African family court

Family courts in South Africa sit in the High Court, the regional and district magistrate’s courts, and the maintenance court, and they apply the South African Law of Evidence alongside the Children’s Act, the Divorce Act 70 of 1979, and the Maintenance Act 99 of 1998. The phrase “best evidence” has two distinct meanings that get confused in everyday conversation.

The first is the original document rule, sometimes called the best evidence rule, which says that where the contents of a document are in issue, the original must be produced unless a statutory exception applies. The second, broader meaning is simply the evidence that carries the most weight on the facts a court must decide. In family matters the second meaning is what most litigants are really asking about.

Weight is not the same as admissibility. A court can admit a document and then give it very little weight. Weight is decided by relevance, reliability, the source of the evidence, and how well it fits the framework the court is required to apply. In children’s matters that framework is the Children’s Act 38 of 2005, in particular section 7, read with section 9 which makes the best interests of the child of paramount importance.

The best-interests-of-the-child standard

Section 7 of the Children’s Act lists the factors a court must consider when deciding what is in a child’s best interests. Section 28 of the Constitution gives children specific rights, including the right to family care, to basic nutrition and shelter, and to be protected from maltreatment. Every piece of evidence in a care, contact, or guardianship dispute is measured against these provisions.

The section 7 factors include the nature of the personal relationship between the child and each parent or caregiver, the attitude of each parent towards the child and towards the exercise of parental responsibilities and rights, the capacity of each parent to provide for the child’s needs, and the likely effect on the child of any change in circumstances. They also include the child’s age, maturity and stage of development, gender, background, and any physical or psychological special needs.

The practical point for a litigant is this. The best evidence in a children’s matter is evidence that speaks directly to a section 7 factor. A bundle of vague WhatsApp messages is weaker than a focused set of documents that, taken together, prove a clear pattern of care, financial support, or risk.

Documentary evidence that carries weight

Documents are the backbone of a family court bundle. They are typically the most reliable evidence because they are created in the ordinary course of life, before any dispute shapes them, and they can be authenticated. The categories that carry the most weight in practice are set out below.

• Marriage and antenuptial contract documents. The marriage certificate, the antenuptial contract (ANC), and any variation or divorce order. These determine whether a marital regime is in or out of community and frame every financial question in a divorce.
• The settlement agreement. If the parties have a prior settlement, parenting plan, or draft divorce settlement, that document often frames what the court is being asked to make an order of court.
• Bank statements and financial records. Three to six months of bank statements, payslips, SARS returns, and bond and vehicle finance statements. These are central to maintenance, spousal maintenance, and the division of the estate.
• School records. Report cards, attendance records, fee statements, and correspondence from the school. These show primary care, the parent who handles schooling, and continuity for the child.
• Medical records. Clinic cards, vaccination records, and reports from treating doctors or therapists. They establish special needs, the parent who manages healthcare, and the cost of care.
• Proof of residence and household composition. Lease agreements, title deeds, and utility accounts that show where the child lives and who else shares the household.

Where a document cannot be obtained in its original form, the Civil Proceedings Evidence Act 25 of 1965 and the rules of court make provision for certified copies, sworn translations, and the use of documents produced from the records of a business or a state organ. The Law of Evidence Amendment Act 45 of 1988, read with section 42 of the Civil Proceedings Evidence Act, governs when a document will be received despite hearsay concerns.

Communications: messages, emails and social media

Emails, WhatsApp and text messages, and social media posts are admissible in family court provided they are relevant and authentic. They frequently carry decisive weight on questions of parental responsibilities, threats, admissions, and the day-to-day pattern of co-parenting.

The practical difficulty is authenticity and completeness. A court will give far more weight to a full, unbroken thread exported from the device than to a handful of screenshots with no context. Each message should show the date, the time, and the sender, and the bundle should explain how it was generated. Where a message is disputed, the court may require electronic evidence in terms of the Electronic Communications and Transactions Act 25 of 2002.

The Family Advocate’s report

The Family Advocate is a state office established under the Mediation in Certain Divorce Matters Act 24 of 1987 and operates within the Department of Justice. In any divorce or dispute involving children, the court may request the Family Advocate to enquire into the circumstances of the child and to compile a report and, where suitable, a parenting plan.

The Family Advocate’s report is one of the most influential pieces of evidence in a children’s matter. It is drafted by an independent office after interviews with the parents, the children where appropriate, and other relevant people. Although the report is advisory and the court is not bound by it, in practice courts give it considerable weight. The Family Advocate may not be subpoenaed to give evidence, which is one reason the report itself is drafted carefully and is treated as an important standalone document.

The Office of the Family Advocate operates under the Department of Justice and Constitutional Development, and the service is free, although waiting lists can be long.

Expert reports: psychologists and social workers

Beyond the Family Advocate, the court may receive expert evidence from psychologists, clinical social workers, psychiatrists, and forensic financial experts, taking into account expert evidence considerations. Expert evidence is admissible where it assists the court on a matter beyond its own knowledge, and it must comply with the test for the admissibility of expert opinion developed in the case law.

• A psychological assessment may address the bond between a child and each parent, the risk of harm, and the child’s emotional needs, mapped onto the section 7 factors.
• A social worker’s report may follow home visits and observations of the parent-child interaction.
• A forensic financial report may trace assets, value a business interest, or quantify a lifestyle for maintenance purposes.

An expert’s duty is to the court, not to the party who pays the fee. Expert reports are tested in cross-examination, and courts are alert to partisan opinion dressed up as expertise. A balanced, methodologically sound report from a registered professional carries far more weight than an advocacy piece.

Admissibility rules that decide what the court can receive

Admissibility is the gateway. Evidence that is relevant but inadmissible cannot be weighed at all. The core rules litigants should understand are short and clear.

• Relevance. Evidence must tend to prove or disprove a fact in issue. The court will exclude material that is irrelevant or only marginally relevant and unfairly prejudicial.
• Authenticity. The party producing a document or recording must show that it is what it purports to be. Originals or certified copies are preferred.
• Hearsay. Under section 3 of the Law of Evidence Amendment Act 45 of 1988, hearsay is generally inadmissible unless the parties agree, the declarant testifies, or the court admits it in the interests of justice.
• Legality. Evidence obtained unlawfully, such as a recording made in breach of the Regulation of Interception of Communications and Provision of Communication-related Information Act 70 of 2002 (RICA), may be excluded.
• Privilege. Communications between spouses and between lawyer and client are protected by privilege and generally cannot be led without waiver.

How evidence is prepared and presented

A strong bundle is built before it is filed. The work involves identifying the facts in issue, mapping each fact to the available evidence, removing anything that is irrelevant or duplicative, and authenticating what remains. Affidavits must comply with the rules of court, expert reports must meet the standard for expert opinion, and the trial bundle must be paginated and indexed so the court can find anything quickly.

In the Family Law department at Otrebski Attorneys, evidence work is handled by our Sandton team led by Director Nastasja Otrebski. The firm is 100% women-led, holds a Level 4 B-BBEE rating, and carries a 5-star Google rating across 12 reviews. We approach evidence methodically: identify the legal test, assemble only the material that moves the matter forward, and present it in a form the court can act on.

Common mistakes that weaken an evidence bundle

• Dumping every message ever sent instead of the focused threads that prove the point.
• Filing unauthenticated screenshots with no dates, no sender, and no explanation of how they were obtained.
• Using a single partisan expert and ignoring the methodological requirements of the case law on expert opinion.
• Forgetting the section 7 framework in a children’s matter, so the bundle proves nothing the court is required to weigh.
• Including illegally obtained recordings or privileged communications, both of which can be excluded and both of which damage credibility.

Frequently asked questions

What is the best evidence for family court in South Africa?

The best evidence is a focused bundle of relevant and authenticated material that speaks to the specific fact the court must decide, weighed against the best-interests-of-the-child standard in section 7 of the Children’s Act 38 of 2005. It usually combines documentary proof such as bank statements and school records, communications such as emails and WhatsApp messages, and credible expert or Family Advocate reports.

Are WhatsApp messages admissible in family court?

Yes. WhatsApp, text, and email messages are admissible provided they are relevant and authentic. The court will give more weight to a full, unbroken thread exported from the device, showing date, time, and sender, than to a few isolated screenshots. Where authenticity is disputed, the Electronic Communications and Transactions Act 25 of 2002 may apply.

What does the Family Advocate do in a family matter?

The Family Advocate is a state office that enquires into the circumstances of children in divorce and parental disputes and compiles a report, and where suitable a parenting plan, applying the section 7 best-interests standard. The report is advisory, the court is not bound by it, and the Family Advocate may not be subpoenaed to give evidence, but in practice the report carries significant weight.

Is hearsay evidence admissible in family court?

Hearsay is generally inadmissible under section 3 of the Law of Evidence Amendment Act 45 of 1988, read with section 42 of the Civil Proceedings Evidence Act 25 of 1965. It may be admitted where the parties agree, where the declarant testifies, or where the court allows it in the interests of justice, having regard to factors such as reliability and unfair prejudice.

What is the best-interests-of-the-child standard?

The best-interests-of-the-child standard is set out in section 7 of the Children’s Act 38 of 2005 and reinforced by section 28 of the Constitution and section 9 of the Act. It requires a court to consider listed factors such as the relationship between the child and each parent, the capacity of each parent, and the child’s age, maturity and developmental stage, in every matter concerning the child.

Do I need an expert report for a custody dispute?

Not always. The Family Advocate’s report is often sufficient. Where the matter is complex or where specialist issues arise, a psychological assessment by a registered psychologist or a report by a clinical social worker can assist the court. Expert evidence must comply with the test for admissibility of expert opinion and the expert’s duty is to the court, not to the instructing party.

Can recordings be used as evidence in family court?

Recordings can be admitted where they are relevant, authentic, and lawfully obtained. Recordings made in breach of the Regulation of Interception of Communications and Provision of Communication-related Information Act 70 of 2002 (RICA) risk exclusion. Even when admitted, the court decides what weight to give them, and a recording without context often carries less weight than expected.
