Chain of custody refers to the documented, unbroken transfer of evidence from the moment it’s collected through every handling step until it is presented in court. This record shows who handled the evidence, when, where, and in what condition, and it often includes tamper-evident seals and packaging. Maintaining this uninterrupted trail is ethically essential because any break or alteration can cast doubt on the evidence’s authenticity, undermine fairness, and potentially impeach the case if it’s challenged later. It protects due process by ensuring the evidence truly reflects what was collected and has not been contaminated or manipulated. In practice, a clear chain of custody helps investigators, labs, and courts trust the integrity of the results and reduces the risk of wrongful conclusions.

Other descriptions that might refer to ownership of equipment, hierarchical command, or approvals do not address how evidence remains trustworthy and uncontaminated from collection to courtroom presentation.
