Chain of custody

Chain of custody is an unbroken record of who held a specific item, and when, from the moment it was acquired to the moment it left the organisation.

← Equipment management glossary

Also called: custody trail, custody record.

Unbroken is the whole point

A custody record with gaps does not prove less than a complete one — in disputes it often proves nothing at all, because any gap is where the other party places the event. This is why partial tracking of high-value equipment tends to disappoint: the effort is spent, the protection is not obtained.

The practical consequence is that a custody trail has to be produced by the workflow itself rather than by people remembering to document. Anything that depends on discipline will have gaps.

Where it stops being optional

For most equipment, custody records are simply good management. In several contexts they are a requirement: regulated medical devices, calibrated test and measurement equipment, controlled substances, evidence handling, and equipment whose maintenance history has to be demonstrable to an auditor or insurer.

In those settings the record's value is evidentiary, which raises the bar. Timestamps that cannot be edited after the fact, and a log that shows amendments rather than silently overwriting, matter more than in ordinary use.

What breaks a chain in practice

Rarely fraud. Usually four mundane things: informal handovers between colleagues that nobody logs, equipment moved during out-of-hours work, items that go from one job straight to the next without returning to store, and records edited later to "tidy up" — which destroys the very property that made them useful.

What goes wrong without it

A custody trail with gaps offers little protection in a dispute, because the gap is exactly where the other party will place the loss or the damage.

How Itefy handles it

Every Itefy checkout, check-in, location change and condition change is timestamped against the item and kept in its history rather than overwriting the previous state. Read more.

Chain of custody — common questions

Is chain of custody only relevant to regulated industries?

It is a requirement in regulated settings and useful everywhere else. Any organisation that has argued about who damaged something, or lost equipment nobody was accountable for, has had a chain-of-custody problem without naming it.

Do informal handovers between colleagues break the chain?

Yes, and they are the most common cause. If A checks out an item and hands it to B unrecorded, the record says A has it — which is wrong in exactly the situation where you need it to be right.
