What is the chain of custody for evidence?

• A. A documented, uninterrupted transfer of evidence from collection to court to preserve integrity.
• B. A summary of the evidence's contents for the court record.
• C. The chain of custody is a list of all witnesses who handled the evidence.
• D. A single custody log kept by the lead investigator.

Answer: (A)

Chain of custody is about maintaining a continuous, documented trail of evidence from collection to presentation in court. The description that fits best says it is a documented, uninterrupted transfer of evidence from collection to court to preserve integrity. This matters because each transfer or handling event must be recorded—who had the item, when, where it was stored, and how it was secured—so that the evidence remains authentic and untampered. If any part of the chain isn’t documented or is broken, the item’s validity can be challenged and it may be inadmissible.

In practice, chain-of-custody records cover item description and identifiers, packaging and seals, dates and times, and every transfer or custody change, from collection through storage to courtroom presentation. The other options don’t establish a continuous custody record or security of the item: a contents summary doesn’t prove the item’s integrity, a list of witnesses doesn’t document custody transfers, and a single log by the lead investigator omits intermediate hands and movements.
