The Treaty Database contains information on the treaties to which the Kingdom of the Netherlands is a party. The information includes the date on and the place at which the treaty was concluded, the date of its entry into force, where to find the text, the parties (countries, territories and international organizations) with the date of each party’s ratification, its applicability to the European part of the Netherlands, Aruba, Curaçao, Sint Maarten and/or the Caribbean part of the Netherlands (Bonaire, Sint Eustatius, Saba), any reservations, declarations or objections that may have been made, and relations between the different treaties.

New or recent modified treaties


The Kingdom of the Netherlands is the depositary for around 100 international treaties. A depositary has the task of ensuring the proper administration of a treaty: that is, managing information about a treaty’s entry into force and termination, the parties to it, and reservations and declarations that have been made. The text of a treaty determines which state or international organization is the depositary.

As soon as there is a change in the information about one of the treaties for which the Kingdom of the Netherlands is the depositary, the Kingdom publishes a depositary notification in the Treaty Database. You can find the notification in the overview “Depositary notifications” or you can subscribe to the e-mailservice to receive depositary notifications of your choice in your e-mailbox. Click on “Subscribe to depositary notifications” under “More information” in the corner on the right side of this page.

The notifications indicate the most recent changes, but a full and up-to-date overview of the information concerning these treaties is available in the Treaty Database. Changes contained in the notifications have already been incorporated into the Treaty Database.
