Certified True Copies (CTCs) of Multilateral Treaties Deposited with the Secretary-General

The Certified True Copies Database contains PDF version of the Certified True Copy (CTC) of each of the multilateral treaties for which the Secretary-General is a depositary (so-called ex-officio multilateral treaties). While best efforts have been expanded to make all electronic versions of the Certified True Copies available, some might not yet be available online. Should you require the electronic version of a CTC which is not yet available on this website, kindly contact the Treaty Section for further assistance. You may also wish to search the UNTS online collection for the relevant treaty to view its full texts or visit the MTDSG database and consult its Participation Status Pages to obtain the reference document where the text (s) were reproduced..

For more information on this matter, including the definition of the "Certified True Copy", see the on-line version of the "Summary of Practice of the Secretary-General as Depositary of Multilateral Treaties", page 18.
