érvényessé

Érvényessé is a Hungarian term referring to the state or quality of being valid, effective, or legally binding. It originates from the Latin word *validus*, meaning "strong" or "effective." In legal contexts, it is commonly used to describe the validity of contracts, agreements, documents, or rights—i.e., their compliance with legal requirements and capacity to produce legal effects. For example, a contract lacking proper formalities may lose its érvényessé. Similarly, in administrative or procedural law, it denotes the legality of decisions or procedures. More broadly, it can describe how something meets established standards or rules, thereby gaining force or authority.
