Article 11 [Bekrachtiging]

After an interval of not more than two years from the day of which the Convention is signed, the Belgian Government shall place itself in communication with the Governments of the High Contracting Parties which have declared themselves prepared to ratify the Convention, with a view to deciding whether it shall be put into force. The ratifications shall be deposited at Brussels at a date to be fixed by agreement among the said Governments. The first deposit of ratificatons shall be recorded in a procès-verbal signed by the representatives of the Powers which take part therein and by the Belgian Minister of Foreign Affairs.

The subsequent deposit of ratifications shall be made by means of a written notification, addressed to the Belgian Government and accompanied by the instrument of ratification.

A duly certified copy of the procès-verbal relating to the first deposit of ratifications, of the notifications referred to in the previous paragraph, and also of the instruments of ratification accompanying them, shall be immediately sent by the Belgian Government through the diplomatic channel to the Powers who have acceded to it. In the cases contemplated in the preceding paragraph, the said Government shall inform them at the same time of the date on which it received the notification.
