The fees charged by a notary are not only for the time taken in providing his/her certificate or the materials and seals used and supplied.
The fee is also intended to reflect the importance of the work undertaken and the high office and responsibility of the Notary in performing that service. Notaries charges are controlled in any event by legislation and Section 15A of the Public Notaries Act 1979 provides that:
15A. Fees to be charged by Public Notaries
A Public Notary may charge a fee for providing notarial services but that fee shall not exceed the fee for those services fixed from time to time by costs determination (as defined in the Legal Profession Act 2008 section 252).
This costs determination is set out in the Legal Profession (Public Notaries) Determination 2015 which can be viewed by following this link.
