What is the role of chain of custody in legal evidence?

The role of chain of custody in legal evidence is pivotal for establishing the integrity and handling of that evidence. Chain of custody refers to the documented and unbroken transfer of evidence from the moment it is collected until it is presented in court. This process involves keeping meticulous records of who collected the evidence, where it was stored, who handled it subsequently, and how it was transported. By maintaining a clear chain of custody, legal practitioners can demonstrate that the evidence has not been tampered with, altered, or contaminated. This integrity is crucial for the admissibility of the evidence in court, as it reassures judges and juries that the evidence they are considering is credible and trustworthy. Therefore, the chain of custody directly impacts the effectiveness of the legal process and the outcome of cases.
