tühistamiseni

tühistamiseni is an Estonian word that translates to "until cancellation" or "until revoked." It is often used in legal and administrative contexts to denote a period of validity that continues indefinitely until a specific action is taken to terminate it. For instance, a permit or a contract might be valid tühistamiseni, meaning it remains in effect until formally canceled or rescinded.

The term signifies an open-ended duration, contrasting with terms that specify a fixed end date. The responsibility for initiating the cancellation typically lies with one or more parties involved, or it may be contingent upon certain conditions being met or not met. Understanding tühistamiseni is important in Estonian legal documents to correctly interpret the duration and terms of agreements or permissions. It implies a state of ongoing validity that requires active intervention to cease.
