What triggers a retention period?

A retention period doesn’t simply count from the day a record was created. It starts from a defined trigger event — also called the cutoff — after which the retention clock begins to run. Getting the trigger right is just as important as getting the length right.

Common triggers

• End of fiscal or calendar year — common for routine administrative and financial records (“destroy 3 years after end of fiscal year”).
• Case or matter closure — for case files, the clock starts when the case is closed.
• Contract or agreement expiration — retention runs from the end of the contract term.
• Superseded or obsolete — the record is replaced by a newer version (e.g., policies, manuals).
• Separation or termination — many personnel records are retained for a period after an employee leaves.
• Event-based triggers — completion of an audit, end of a benefit, disposal of an asset.

Why the trigger matters

Two records with the same retention length can have very different destruction dates depending on their triggers. A “7 years” retention means little until you know “7 years after what.” A clear trigger makes disposition predictable and automatable — the system can calculate each record’s destruction date and act on it.

Cutoff and disposition

In practice, records are often cut off at a regular interval (commonly the end of the fiscal year) and the retention period applied from there, which lets an organization process disposition in orderly batches rather than record by record. This is why a retention schedule specifies both the period and its trigger — and why defensible disposition depends on tracking triggers accurately for every record series.
