E-Discovery and Litigation Data
Preservation
Custodian interviews establish what devices, accounts, applications, and storage locations a person uses for work, what relevant material they hold, and what practices affect retention such as deletion habits or personal device use.
They inform preservation scope and collection planning.
Alternative Names:
Custodian Questionnaire, Data Custodian Interview
Why it Matters?
These interviews surface the data sources no system inventory captures: the personal phone used for work texting, the ephemeral messaging app the team adopted, the local drive where someone keeps working copies. Skipping them produces collections that appear complete and are not, and the omission typically surfaces when the other side obtains the material from another custodian.
