If you've ever been asked to provide an affidavit, a sworn statement, or a declaration — and weren't entirely sure what the difference was — you're in good company. The terms get used interchangeably, even by people who really should know better. But in South African law, they aren't all the same thing.
This guide breaks down each one in plain English, when you'd use it, and how to make sure yours is drafted properly.
The Short Version
| Document | Sworn? | Witnessed by Commissioner of Oaths? | Legal Weight |
|---|---|---|---|
| Affidavit | Yes | Yes | High — accepted in court |
| Sworn Statement | Yes | Yes | Same as affidavit (often the same thing) |
| Declaration | Sometimes | Not always | Varies — context-dependent |
Now let's unpack what that actually means.
What is an Affidavit?
An affidavit is a written statement of facts that you swear (or affirm) to be true in front of a commissioner of oaths — typically a police officer, magistrate, notary, or certain bank officials.
Affidavits are governed by the Justices of the Peace and Commissioners of Oaths Act and must follow specific formalities to be valid:
- The deponent (the person making the statement) must sign it in the presence of a commissioner of oaths
- The commissioner must verify the deponent's identity
- The commissioner must confirm the deponent understands the contents and the consequences of lying under oath
- Specific wording must be used to identify the document as a sworn affidavit
Examples of when you'd need an affidavit:
- A car accident statement for your insurer or the Road Accident Fund
- A statement supporting a court application
- A lost ID or driver's licence affidavit for Home Affairs
- A statement in a civil dispute or criminal case

What is a Sworn Statement?
In most South African contexts, "sworn statement" is just another name for an affidavit. Both are written, both are signed in front of a commissioner of oaths, and both carry legal weight.
You'll sometimes see "sworn statement" used informally — for example, by police taking a statement from a witness — but if it's been signed and commissioned, it's effectively an affidavit.
The phrase "sworn statement" is often preferred when:
- The document is for general purposes rather than a specific legal proceeding
- The person taking the statement (e.g., a SAPS officer at the station) wants the statement on record but isn't drafting it for a specific court matter
In short: an affidavit is always a sworn statement, but the term "sworn statement" is sometimes used more loosely.
What is a Declaration?
A declaration is where things get interesting. The word "declaration" is used in several different contexts in South Africa, and it doesn't always mean the same thing.
1. Sworn Declaration
This is essentially an affidavit by another name — you're declaring that something is true under oath. Carries the same legal weight as an affidavit.
2. Solemn Declaration / Affirmation
For people who, for religious or personal reasons, can't or won't swear an oath, the law allows them to affirm the contents instead. The legal effect is identical to an affidavit. This is recognised under the same legislation that governs affidavits.
3. Statutory Declaration
A formal written statement made for a specific statutory or administrative purpose — often for documents being submitted abroad. Sometimes requires notarisation rather than just commissioning.
4. General Declaration
This is the loose one — a written statement someone makes "declaring" something, often without being formally sworn. For example, a buyer might sign a declaration confirming they've inspected a vehicle. These don't always carry the same legal weight as a sworn affidavit, and shouldn't be confused with one.
When Should You Use Which?
Here's a quick guide based on the situation:
For court matters (civil or criminal) 👉 Affidavit. Always. No shortcuts.
For insurance claims and the Road Accident Fund 👉 Affidavit. Read more about RAF claims at the official RAF claims page.
For Home Affairs (lost ID, name change, etc.) 👉 Affidavit, sworn at any SAPS station.
For workplace declarations or HR matters 👉 Depends on the company — usually a sworn affidavit, sometimes a general declaration.
For statements being used overseas 👉 Often a notarised statutory declaration. Speak to a notary public.
For witness statements at a police station 👉 Sworn statement (essentially an affidavit) — done by SAPS staff.

What Happens If You Lie in an Affidavit?
This is worth understanding clearly. Lying in a sworn affidavit is a criminal offence in South Africa — specifically, the crime of perjury, or contravening the Justices of the Peace and Commissioners of Oaths Act.
Penalties can include fines or imprisonment. Even if you're never prosecuted, a false affidavit can have you ejected from a court case, your insurance claim rejected, and your credibility destroyed.
Always tell the truth in any sworn document — and don't sign anything you haven't carefully read and don't fully understand.
Where Can You Get a Document Commissioned?
Free of charge, at any of the following:
- SAPS stations — police officers above the rank of Sergeant
- Magistrates' courts
- Some banks — many bank managers are commissioners of oaths
- Post offices — depending on the branch
- Attorneys — most attorneys are also commissioners of oaths
Note: A commissioner of oaths cannot commission a document in which they have a personal interest. So your attorney can't commission an affidavit for a case they're working on for you — you'll need someone independent.
