Chain of Custody

Updated Jan 30, 2024 ·

Chain of Evidence​

Also known as the Chain of Evidence, the Chain of Custody is the documented process that tracks the handling, transfer, and storage of evidence from its collection to its final presentation in court or other legal settings.

  • Records each step of evidence collection, transfer, and storage.
  • Logs when evidence changes hands, including who, when, and why.
  • Securely store evidence to prevent unauthorized access or loss.
  • Evidence should be labeled and stored in a sealed container.

Evidence Logs​

A clear chain of custody helps ensure evidence is admissible in court by demonstrating its integrity. Evidence logs should accompany each piece of evidence and should contain the following events:

  • Initial collection of evidence
  • Transfer of evidence
  • Storage of evidence
  • Opening and resealing of evidence container

Each time an entry is recorded in the evidence log, it should contain:

  • Investigator name
  • Current date and time
  • Nature of the action
  • Purpose of the action

Breach of Chain of Custody​

A breach in the Chain of Custody can undermine the integrity of evidence, raising concerns about its authenticity and reliability in legal cases.

  • Defense teams may challenge the admissibility of evidence.
  • Breaks in custody make it harder to verify the evidence's origin.
  • Evidence may be altered or contaminated, weakening its credibility.
  • Reconstructing custody gaps can slow down the legal process.
