If you’ve emigrated – or you’re planning to – you may suddenly find yourself dealing with naturalisation certificates, dual citizenship rules, and questions like: “Am I still a South African citizen if I take another passport?”
South Africa’s citizenship rules have also changed recently, especially around automatic loss of citizenship when taking another nationality, so it’s more important than ever to understand what your documents mean and when you might need them.
While Apostil.co.za doesn’t give legal advice or decide anyone’s status, we do help emigrants get the proof of status they need – naturalisation certificates, unabridged birth records, apostilles and more – so they can deal confidently with foreign authorities.

What is a South African naturalisation certificate?
A naturalisation certificate is the formal document issued to someone who has been granted South African citizenship by naturalisation, rather than by birth or descent.
It normally confirms:
- Your full personal details
- The date you were naturalised
- The legal basis under which naturalisation was granted
- An official reference number and issuing authority
In practice, this certificate is often needed when you:
- Apply for passports or ID after a long time abroad
- Prove your status to foreign immigration authorities
- Claim citizenship by descent for your children
- Deal with South African Home Affairs after system changes or data errors
If you no longer have your original document, you may need a replacement or confirmation of naturalisation from Home Affairs. Apostil.co.za can help with retrieving these types of civic records and preparing them for overseas use.

Naturalisation vs citizenship by birth or descent
It’s useful to distinguish:
- Citizenship by birth – usually where you were born in South Africa and met the legal requirements at the time.
- Citizenship by descent – often where you were born abroad to South African parents.
- Citizenship by naturalisation – where you met residence and other criteria and applied to become a South African citizen.
Foreign authorities may treat these categories differently, especially when you:
- Apply for dual citizenship
- Register children’s births abroad
- Apply for ancestry-based visas
That’s why they may specifically ask to see a naturalisation certificate (if that’s how you became South African) together with your unabridged birth certificate and other civic records.

Dual citizenship: what has changed?
For many years, South Africans who voluntarily acquired a foreign citizenship (for example by naturalising in the UK, Australia, Canada, etc.) could automatically lose their South African citizenship if they did not first apply for formal retention of South African citizenship in terms of section 6(1)(a) of the Citizenship Act.
That meant:
- You applied for another citizenship without getting retention.
- By operation of law, you were treated as having lost South African citizenship on the day you acquired the new one.
- Many people only discovered this when they tried to renew a South African passport years later.
The court decisions
- In June 2023, the Supreme Court of Appeal held that this automatic loss provision (section 6(1)(a)) was unconstitutional, and that those who had lost citizenship under it were deemed not to have lost it.
- On 6 May 2025, the Constitutional Court confirmed this invalidity and the order that affected citizens are deemed never to have lost their South African citizenship.
In plain English:
- The automatic loss rule has been struck down.
- People who previously “lost” citizenship under that rule are, in law, treated as if they never lost it.
The Department of Home Affairs has indicated it is developing systems so affected South Africans can confirm their reinstated citizenship, including from abroad.
Where “retention of citizenship” still fits in
Even though section 6(1)(a) has been declared invalid, the concept of retention of South African citizenship remains important, because:
- Foreign lawyers, consulates and older website guidance may still refer to the previous rules.
- Banks and institutions in South Africa may still ask for evidence that your citizenship has not been lost.
- Administrative systems at Home Affairs will take time to catch up with court rulings.

If you previously applied for retention and have mislaid the letter, you may want to retrieve a copy or obtain supporting documentation, especially if a foreign authority insists on it despite the changed legal position.
How naturalisation certificates interact with dual citizenship
If you are a naturalised South African who later emigrates and acquires another citizenship, your document trail might include:
- Your South African naturalisation certificate
- Your unabridged birth certificate (from your country of birth)
- Your foreign naturalisation certificate from the new country
- Possibly a retention letter (if you previously applied for one)
Foreign and South African authorities may use these documents to:
- Confirm how and when you became South African
- Confirm that you held South African citizenship at the time you passed it on to your children
- Determine whether you qualify for certain visas, passports or citizenship claims
In some cases, you may need to have your South African naturalisation certificate apostilled or authenticated for use abroad:

With the old automatic-loss rule now struck down, many South Africans abroad are in a better position than they realise, but they still need the right paperwork in hand.
If you’re unsure which certificates you need, or you’re abroad and battling to get anything out of Home Affairs, you don’t have to do it alone.
