Plan a collection before choosing a destination
Identify where the evidence is held, who can authorize access and whether a remote export, controlled device handoff or agreed on-site visit fits the source. A courthouse or industry nearby does not establish an evidence-storage facility.
- A device handoff needs an agreed receiver, item identifiers, packaging, condition and a custody receipt.
- A tenant export needs an authorized administrator, retention and licence details, selected records and a secure transfer route.
- A multi-office matter needs one source register showing source owner, location, collection status and unresolved access.
- Use the regional page for relevant venues and source questions. Confirm visit and transport details through the existing intake route.
