Event-Based Retention
Event-based retention is a disposition method in which a record's retention period does not begin counting until a specific triggering event occurs, rather than starting on a fixed creation or filing date.
Event-based retention ties the start of a record’s retention period to the occurrence of a defined event instead of to the moment the record was created or filed. Common triggers include employee separation, contract termination, project closeout, equipment disposal, or the death of an individual. Once the event is logged, the clock starts and the prescribed retention period runs to its end, after which the record becomes eligible for disposition. This approach matters because many records have no meaningful or predictable value until the underlying activity concludes; destroying them on a fixed calendar would risk losing information still needed for legal, fiscal, or operational reasons. For example, a personnel file might be retained for a set number of years “after separation” rather than after hire. The challenge is operational: systems must reliably capture and timestamp the triggering event, since a missed or unrecorded trigger can leave records in indefinite limbo. Well-designed retention schedules pair clear event definitions with metadata that records when each trigger fired, keeping disposition defensible and auditable.
