Entry into force — Definition and meaning

In law, coming into force or entry into force is the process by which legislation, regulations, treaties and other legal instruments come to have legal force and effect. The term is closely related to the date of this transition. The point at which such instrument comes into effect may be set out in the instrument itself, or after the lapse of a certain period, or upon the happening of a certain event, such as a proclamation or an objective event, such as the birth, marriage, reaching a particular age or death of a certain person. On rare occasions, the effective date of a law may be backdated to a date before the enactment.
