The phenomenon of juridical acts exists in most, if not all, legal systems of the world. The concept of a juridical act, however, has mainly become popular in the legal systems that belong to the civil law tradition. In common law countries, one rather speaks of the exercise of a legal power. A consequence of this difference between legal cultures is that the English term "juridical act" has not reached the level of general usage.
A juridical act is an act performed with the intention to bring about legal consequences, specifically one where the law connects legal consequences to the act for the reason that they were intended.
Alternative expressions for "juridical act" in English are "legal act" and "legal transaction."(Introduction to Law by Jaap Hage, Antonia Waltermann, Bram Akkermans).
