Question

A treaty must do what to be considered valid

Answer 1

The ratification process varies according to the laws and Constitutions of each country. In the U.S., the President can ratify a treaty only after getting the “advice and consent” of two thirds of the Senate. Unless a treaty contains provisions for further agreements or actions, only the treaty text is legally binding.

Answer 2

Answer:

Be signed by the leaders of the different sides.

Explanation:

To make a treaty valid it must be signed by the leader of the party from their side and the other side as well. Once the rules and terms are read and accepted that signature will make the treaty valid amongst the parties.
