spoliation
n.
The intentional destruction, alteration, or concealment of evidence, especially documents.
Notes
In general, courts have found that the routine destruction of records after reasonable, scheduled retention periods is not spoliation. However, if there is a reasonable likelihood of litigation or audit, destruction of relevant records may be considered spoliation, even if the retention period has passed.
