A subpoena duces tecum is particularly useful because it specifically targets documents rather than testimonial evidence, allowing for the acquisition of necessary information without requiring the non-party to testify in court.

Using this approach is crucial for maintaining the integrity and relevance of the documents requested, and it provides a formal means of accessing the information that might be essential for Client's case. Additionally, the implementation of a subpoena duces tecum aligns with procedural rules regarding the handling of evidence, and non-parties are obliged to comply with such subpoenas unless there are legal grounds for objection.
