The term "chain of custody" refers specifically to the process of maintaining and documenting the handling of evidence throughout an investigation. This concept is critical in law enforcement because it ensures that evidence is preserved in a manner that protects its integrity for use in court. The chain of custody involves detailed records of who collected the evidence, how it was collected, where it has been stored, and who has had access to it over time. This documentation is essential to establish that the evidence presented in court is the same as that which was gathered at the crime scene, thereby preventing contamination or tampering.

Properly maintaining the chain of custody is fundamental in legal proceedings, as any break in this chain can lead to questions regarding the reliability of the evidence. Therefore, understanding and correctly executing the chain of custody is a key responsibility in policing and criminal investigations.
