Instrument of Ratification

Where a State (or regional economic integration organization) wishes to become party to the Convention, it must express its consent to be bound by it. Consent most often takes the form of ratification, acceptance or approval and accession, which internationally have the same legal effect (see Article 2 §1 b), 14 and 15 of the 1969 Vienna Convention).

  • The instrument of ratification

The instrument of ratification must be signed by one of the three entitled people: the Head of State, Head of Government or Minister for Foreign Affairs.

Example instrument of ratification (or of acceptance, approval or accession depending on the case):

 English |  Français |  Español |  Русский |  العربية

  • The deposit of the instrument of the ratification

The original of the signed instrument of ratification, of acceptance, of approval or of accession must be deposited with the Director General of UNESCO. Only after such deposit, the ratification process will be completed. Three months after the deposit of the instrument, the State shall become a Party to the Convention (Article 29 of the Convention).
