Notary Public and a Commissioner for Oaths; the difference.
Many people confuse these two, but they are not the same, even though both deal with documents and oaths.
1. Commissioner for Oaths
A Commissioner for Oaths is a person authorized to primarily:
👉Administer oaths and affirmations
👉Take affidavits and statutory declarations
They are appointed by the Chief Judge of a State or the Chief Justice of the Federal High Court and their authority works well for everyday legal matters that stay within Nigeria,
2. Notary Public
They are appointed directly by the Chief Justice of Nigeria, making it a national appointment that carries significantly more weight.
Beyond witnessing oaths, a Notary Public can;
👉certify true copies of original documents,
👉prepare formal notarial acts,
👉and most importantly, produce documents that are recognised across international borders.
This is what embassies, foreign universities, international courts, and overseas businesses actually accept.
NOTE:
On the question of professional qualification, both offices are connected to the legal profession but at different levels.
👉A Commissioner for Oaths is typically a legal practitioner, though in some states non-lawyers holding certain public offices may be appointed.
👉A Notary Public however must be a legal practitioner of good standing with a minimum of Seven (7) years post-call experience. This means they must have been called to the Nigerian Bar and must have practiced actively for at least 7 years before qualifying for the appointment.
This requirement reflects the seriousness and international responsibility the office carries.
The practical rule is straightforward.
👉If your document is staying in Nigeria, a Commissioner for Oaths is usually enough.
👉If your document is travelling outside Nigeria for any reason at all, whether for a visa, foreign degree verification, international business, or embassy submission, you need a Notary Public.
Every Notary Public holds the powers of a Commissioner for Oaths, but a Commissioner for Oaths cannot perform the international authentication duties of a Notary Public.
Therefore, when you are unsure, always choose the Notary Public.
