Question

When is the ratification of a constitutional amendment required?​

Answer 1

$\huge\rm{ \red{Answer}}$

A proposed amendment becomes part of the Constitution as soon as it is ratified by three-fourths of the States.

Requirement

Proposed amendments must be ratified by three-fourths of the states in order to take effect. Congress may set a time limit for state action. The official count is kept by Office of the Federal Register at the National Archives. Legislatures must return specific materials to show proof of ratification.

Note

Under Article V of the Constitution, there are two ways to propose and ratify amendments to the Constitution. To ratify amendments, three-fourths of the state legislatures must approve them, or ratifying conventions in three-fourths of the states must approve them.
