<P> Modern treaties, regardless of subject matter, usually contain articles governing where the final authentic copies of the treaty will be deposited and how any subsequent disputes as to their interpretation will be peacefully resolved . </P> <P> The end of a treaty, the eschatocol (or closing protocol), is often signaled by a clause like "in witness whereof" or "in faith whereof," the parties have affixed their signatures, followed by the words "DONE at," then the site (s) of the treaty's execution and the date (s) of its execution . The date is typically written in its most formal, longest possible form . For example, the Charter of the United Nations was "DONE at the city of San Francisco the twenty - sixth day of June, one thousand nine hundred and forty - five ." If the treaty is executed in multiple copies in different languages, that fact is always noted, and is followed by a stipulation that the versions in different languages are equally authentic . </P> <P> The signatures of the parties' representatives follow at the very end . When the text of a treaty is later reprinted, such as in a collection of treaties currently in effect, an editor will often append the dates on which the respective parties ratified the treaty and on which it came into effect for each party . </P> <P> Bilateral treaties are concluded between two states or entities . It is possible, however, for a bilateral treaty to have more than two parties; consider for instance the bilateral treaties between Switzerland and the European Union (EU) following the Swiss rejection of the European Economic Area agreement . Each of these treaties has seventeen parties . These however are still bilateral, not multilateral, treaties . The parties are divided into two groups, the Swiss ("on the one part") and the EU and its member states ("on the other part"). The treaty establishes rights and obligations between the Swiss and the EU and the member states severally--it does not establish any rights and obligations amongst the EU and its member states . </P>
