What best supports the admissibility of documentary evidence in fraud investigations?

• A. A complete chain of custody showing every person who handled the evidence.
• B. Randomly selecting who saw the evidence.
• C. Only preserving original copies without any logs.
• D. Treating evidence as informal notes.

Answer: (A)

Documentary evidence is admissible when there is a verifiable chain of custody that shows every person who handled the evidence and the times it changed hands. This chain of custody proves authenticity and integrity, making it clear the document hasn’t been altered since collection. In fraud investigations, where the accuracy and reliability of documents are central to proving misrepresentation or deceit, a detailed record of who observed or touched the evidence, when, and under what conditions helps demonstrate that the evidence is trustworthy and has been kept in a controlled, documented manner. Without this, even an original document could be questioned as having been tampered with or substituted, undermining its credibility. Randomly selecting who saw the evidence leaves gaps in the record; preserving only original copies without logs makes it difficult to prove custody; treating evidence as informal notes fails to meet the formal standards needed for admissibility. Therefore, a complete chain of custody is the best support for admissibility.
