Ratification is a method by which a state becomes a party to a treaty of which it is not a signatory.

Ratification is a formal document emanating from the competent authority of a state designating a person or persons to represent the state for negotiating, adopting or authenticating the text of a treaty.

Ratification is some favor or advantage given to someone in return for something they have done.

Ratification is the international act whereby “a State establishes on the international plane its consent to be bound by a treaty”.

Ratification is a unilateral statement made by a state at the time of signing a treaty, whereby it purports to exclude or modify the legal effect of certain provisions of the treaty in their application to that state.
