Reporting an error

If you notice that the Office has made a mistake in the information on the registration certificate or in the changes made to the National Trademarks Register, you can notify the Office so that it can make the necessary corrections.

NOTE: if you are responsible for the error, refer to the section “Updating trademark information” under the heading “The life of your trademark”.



The request for correction must concern a trademark that is already on the National Trademarks Register.

NOTE: For international trademarks designating Monaco, you should contact the International Bureau of the World Intellectual Property Organisation, which is responsible for the International Register (see the section entitled “The life of your international trademark” under the heading “The life of your trademark”).


Who can report an error?

The holder of the trademark listed on the National Trademarks Register, or anyone who disclosed the information processed by the Office.


How to report an error

Your correction application must be on plain paper and must include the following:

  • The name and address of the person requesting a correction.
  • The registration number of the trademark concerned.
  • A copy of the update form.
  • The section of the Annex to the Official Journal of Monaco in which the error appears (Annex number and page number).

IMPORTANT: if the mistake concerns the content of a registration certificate, it should be enclosed with the correction request so that it can be destroyed.


How much does a correction cost?

The correction is free if the error was caused by the Office when processing the information.
