Non-disclosure is failing to tell your insurer something material when you take out or renew car insurance, and it is one of the top reasons claims get rejected in South Africa. Material facts include who the main driver is, where the car is parked overnight, previous claims and any modifications. If you leave these out, your insurer can refuse to pay.
The duty to disclose is on you, not the insurer, so getting it right when you take out the policy protects your claim later.
This guide explains what counts as material, the common mistakes, and how to stay covered.
What counts as a material fact
A material fact is anything that could affect the insurer's decision to cover you or the premium they charge. Common examples:
- Who actually drives the car most (the regular driver)
- Where the car is parked overnight
- Previous accidents, claims or rejections
- The true use of the car (private vs business)
- Modifications and accessories
- Other drivers' ages and licence history
If in doubt, declare it.
The regular driver trap
A very common rejection is naming an older, lower risk person as the main driver when a younger, higher risk driver actually uses the car most (sometimes called fronting). If a claim happens and the insurer finds the real regular driver was undeclared, it can reject the claim. Always name the genuine regular driver.
Why insurers can reject for non-disclosure
When you take out cover you have a duty of good faith to disclose material facts. If you do not, the insurer may have priced or accepted the risk incorrectly. South African law and policy wording allow insurers to reduce or reject a claim, or void the policy, where material non-disclosure is proven.
Common non-disclosure mistakes
- Understating the younger driver's role
- Not updating a change of address or overnight parking
- Failing to mention a previous claim or cancellation
- Using a private policy for business or ride hailing use
- Not declaring modifications
- Leaving accessories or a sound system uninsured
Many of these are honest oversights, but they can still cost you the claim.
How to keep your cover valid
- Answer every question fully and honestly when you take out cover
- Tell the insurer about anything that might be relevant, even unprompted
- Update your details whenever they change (address, drivers, use)
- Keep proof of what you declared and when
- Re check disclosures at renewal
If a claim is rejected for non-disclosure you disagree with, you can dispute it and escalate to OSTI.
Frequently asked questions
What is non-disclosure in car insurance?
It is failing to tell your insurer a material fact when taking out or renewing cover, such as the real main driver, overnight parking, previous claims or modifications. It is a top reason claims get rejected.
What must I declare to my insurer?
Anything material: the genuine regular driver, where the car parks overnight, previous claims or cancellations, the car's true use, modifications and accessories, and other drivers' details. If unsure, declare it.
What is fronting?
Fronting is naming a lower risk person, often an older parent, as the main driver when a higher risk driver actually uses the car most. It is a form of non-disclosure and can lead to a rejected claim.
Can my claim be rejected even if non-disclosure was accidental?
Yes. Even an honest oversight of a material fact can lead to a reduced or rejected claim. The duty to disclose is on you, so be thorough and update changes promptly.
Do I have to update my insurer when things change?
Yes. Tell your insurer when your address, overnight parking, regular driver or car use changes. Out of date details can amount to non-disclosure at claim time.
Can I dispute a non-disclosure rejection?
Yes. Ask for the rejection in writing, show evidence you did disclose or that the fact was not material, use the internal dispute process, and escalate to OSTI if unresolved.
Does using my car for business need to be declared?
Yes. Business use, deliveries or ride hailing usually need to be declared and may need different cover. Using a private policy for business use can be treated as non-disclosure.
