Why is maintaining a chain of custody important when handling evidence?

• A. It guarantees the evidence will be admissible in all jurisdictions.
• B. It documents every change in possession or handling to preserve integrity.
• C. It is optional for minor items.
• D. It increases the weight of the evidence.

Answer: (B)

Maintaining a chain of custody means keeping a documented, chronological record of every person who handles the evidence, every transfer, and every change in its condition. This practice preserves the evidence’s integrity by showing it hasn’t been swapped, altered, or contaminated since collection. In court, that clear trail helps prove that the item presented is the same one that was found and collected, which supports its reliability and authenticity. If the chain isn’t properly maintained, the evidence can be challenged or excluded because its origin and condition cannot be trusted. This discipline applies to all evidence, not just large or dramatic items, and it doesn’t by itself guarantee admissibility in every jurisdiction or alter the evidentiary weight; it simply ensures the evidence remains trustworthy and defendable.
