Evidence in South Africa refers to any information, testimony, or material presented in court to prove or disprove a fact in a legal case. It is the foundation of justice — no person can be convicted or acquitted without evidence that supports the decision.
On this page, you will learn how evidence is defined in South African law, the different types of evidence, how it is presented in court, what makes evidence admissible or not, and what citizens should know about their rights during evidence collection and trial.
Understanding Evidence under South African Law
The law of evidence in South Africa determines what information a court can accept and how it must be presented to ensure fairness in legal proceedings.
It is guided mainly by common law principles, supported by several Acts of Parliament that govern specific types of evidence.
The goal of the evidence system is to ensure that:
- Only reliable and relevant information is used.
- Both sides have an equal opportunity to present and challenge evidence.
- The court reaches a fair and truthful judgment based on facts.

Types of Evidence Recognised in South African Law
| Type of Evidence | Description | Example |
|---|---|---|
| Oral Evidence | Spoken testimony given by a witness in court under oath. | A witness describing what they saw at the crime scene. |
| Documentary Evidence | Written records or printed materials used to prove facts. | Contracts, emails, bank statements. |
| Real Evidence | Physical objects presented in court. | Weapons, clothing, fingerprints. |
| Digital or Electronic Evidence | Data or information stored electronically. | CCTV footage, WhatsApp messages, voice notes. |
| Expert Evidence | Opinions from qualified specialists to assist the court. | DNA analysts, forensic pathologists, accountants. |
| Hearsay Evidence | Second-hand information (what someone else said). | Usually inadmissible unless permitted by the court under strict conditions. |
Admissibility of Evidence
For evidence to be accepted by a South African court, it must meet three main criteria:
- Relevance – The evidence must relate directly to the issue being decided.
- Competence – The person providing the evidence must be legally capable and able to understand the duty to tell the truth.
- Lawful Acquisition – Evidence obtained through illegal means (like forced confessions or unlawful searches) may be excluded under Section 35(5) of the Constitution.
Example:
If police obtain a confession by threatening a suspect, that confession is inadmissible, even if it is true.
How Evidence Is Presented in South African Courts
- Witness Testimony
- Witnesses take an oath to tell the truth.
- The side that called the witness conducts examination-in-chief.
- The opposing side performs cross-examination to test reliability.
- Documentary and Physical Evidence
- Documents or objects must be properly identified and linked to the case.
- Expert Witnesses
- Experts interpret technical findings, such as forensic or medical results.
- Closing Arguments
- Both parties summarise how the evidence supports their case.
The judge or magistrate then decides which evidence is credible and relevant to the verdict.
Real Example
In the Oscar Pistorius murder trial (2014–2016), various forms of evidence were presented:
- Ballistic evidence (real evidence) showed bullet trajectories.
- Text messages (digital evidence) reflected the relationship between the parties.
- Expert evidence helped reconstruct the shooting incident.
The court used all these forms to assess intention and credibility, showing how evidence from different sources builds a complete legal picture.
Rules about Hearsay and Unlawfully Obtained Evidence
- Hearsay evidence (information not personally observed by the witness) is generally inadmissible, unless:
- The original speaker testifies, or
- The court finds it in the interests of justice to accept it.
- Illegally obtained evidence (for example, secret recordings without consent) may be excluded if it violates constitutional rights, unless the court decides that admitting it serves justice more than excluding it.
5 Important Points Every South African Should Know about Evidence
- Not all evidence is accepted in court — it must be relevant and lawful.
- Digital evidence (like WhatsApp messages) can be used if properly verified.
- You have the right to challenge evidence presented against you.
- Unlawful searches or forced confessions can make evidence invalid.
- Expert witnesses play a crucial role in proving complex technical facts.
Implications of Evidence Law in South Africa
The law of evidence ensures that justice is based on facts and fairness, not speculation or manipulation.
It protects both the accused and the victim by requiring:
- Proper investigation and verification.
- Fair opportunity to question or dispute claims.
- Accountability for how police and prosecutors gather information.
Strong evidence strengthens public confidence in the justice system, while weak or illegally obtained evidence can lead to wrongful convictions or acquittals.

FAQs About What Is Evidence in South Africa
Evidence is one of the most important parts of any South African court case — whether civil or criminal.
These FAQs explain what evidence means under South African law, what types of evidence are accepted in court, and how judges decide what can and cannot be used during a trial.
What is evidence in South Africa?
Evidence in South Africa refers to any information or material presented in court to prove or disprove a fact in a legal case.
It can include oral testimony, documents, photographs, physical objects, or digital records.
Evidence helps the court decide whether a person is guilty, liable, or innocent under the law.
What law governs evidence in South Africa?
Evidence in South Africa is mainly governed by common law (court decisions) and several statutes, including:
- The Law of Evidence Amendment Act, 1988 (Act 45 of 1988)
- The Criminal Procedure Act, 1977 (Act 51 of 1977)
- The Civil Proceedings Evidence Act, 1965 (Act 25 of 1965)
- The Electronic Communications and Transactions Act, 2002 (Act 25 of 2002) for digital and electronic evidence
These laws ensure that all evidence presented is reliable, relevant, and fair.
What are the main types of evidence in South African courts?
There are several types of evidence recognised by law:
- Oral evidence – spoken testimony by witnesses in court.
- Documentary evidence – written or printed documents, such as contracts, letters, or records.
- Real evidence – physical items like weapons, clothing, or fingerprints.
- Digital evidence – emails, text messages, CCTV footage, or data from devices.
- Circumstantial evidence – facts that indirectly suggest guilt or innocence (e.g. being found near the crime scene).
- Expert evidence – opinions from specialists such as forensic scientists or doctors.
What makes evidence admissible in court?
Evidence is admissible if it meets three main requirements:
- Relevance – it must help prove or disprove a fact in the case.
- Reliability – it must be credible and obtained lawfully.
- Legality – it must comply with constitutional and procedural rules.
If evidence is illegally obtained — for example, through an unlawful search — it may be excluded under Section 35(5) of the Constitution.
What is hearsay evidence in South Africa?
Hearsay evidence is any statement made outside of court that is presented to prove the truth of what it says.
For example, “My friend told me he saw the accused” is hearsay.
Hearsay is not generally admissible unless it falls under exceptions allowed by Section 3 of the Law of Evidence Amendment Act, 1988, such as:
- The original speaker is unavailable
- The parties agree to admit it
- The court decides it is in the interests of justice
What is circumstantial evidence?
Circumstantial evidence relies on inference rather than direct proof.
It allows the court to draw logical conclusions from facts that point toward guilt or innocence.
For example, finding the accused’s fingerprints on a weapon used in a murder is circumstantial but powerful when combined with other evidence.
Can electronic evidence be used in South African courts?
Yes. Under the Electronic Communications and Transactions Act, 2002, digital evidence such as:
- Emails
- Social media posts
- CCTV recordings
- WhatsApp messages
can be used in court, provided they are authentic, relevant, and unaltered.
Courts often require expert verification to confirm that the evidence has not been tampered with.
What is the difference between direct and indirect evidence?
- Direct evidence proves a fact immediately, such as an eyewitness seeing the crime happen.
- Indirect (circumstantial) evidence requires inference — for example, seeing the accused running away with stolen goods.
Both are accepted in South African courts, and a conviction can be based solely on strong circumstantial evidence.
What is the burden of proof in South African law?
The burden of proof means the responsibility to prove the facts of a case.
- In criminal cases, the burden lies with the State, which must prove the accused’s guilt beyond reasonable doubt.
- In civil cases, the burden lies with the plaintiff, who must prove their case on a balance of probabilities.
What is the role of witnesses in giving evidence?
Witnesses are essential to the justice process.
They must take an oath to tell the truth and may be questioned by both the prosecution (or plaintiff) and the defence.
Lying under oath is a criminal offence known as perjury, punishable under the Criminal Law Amendment Act, 1997.
Can illegally obtained evidence be used in court?
Not always. Under Section 35(5) of the Constitution, evidence obtained in violation of rights — such as through torture, unlawful searches, or forced confessions — must be excluded if it would make the trial unfair or damage justice.
However, courts may admit such evidence if it was obtained in good faith or without serious rights violations.
What is expert evidence and when is it used?
Expert evidence is testimony given by a specialist who has technical or scientific knowledge beyond the court’s expertise.
It is used in cases involving forensics, DNA, accounting, medicine, or psychology.
Experts must be impartial and are cross-examined like other witnesses to test credibility.
Why is evidence important in South African courts?
Evidence forms the foundation of justice.
It ensures that verdicts are based on facts, not assumptions, and that innocent people are protected while guilty parties are held accountable.
South African evidence law aims to balance truth-finding, fairness, and constitutional rights, which are central to every trial.
Conclusion: Understanding Evidence in South Africa
Evidence in South Africa is what separates truth from accusation.
It ensures that convictions are not based on rumour or emotion, but on facts that can stand up in court.
By knowing how evidence works — from digital messages to forensic DNA — every citizen can better protect their rights, understand trials, and participate meaningfully in the justice process.
Justice in South Africa depends on one thing above all: evidence that is truthful, lawful, and fair.
