Justipedia explains Ratification
The word "ratification" is also commonly used when a certain number of states must agree on something for it to become valid.
For example, the U.S. Constitution had to be ratified by the states before it could go into existence. The ratification of the U.S. Constitution took 10 months during the year 1787. The first state to provide approval for the U.S. Constitution was Delaware. This event happened on Dec. 7, 1787. The U.S. Constitution has been in effect ever since it was formally ratified.
