Rule 26(e) imposes which duty?

• A. Duty to supplement or correct
• B. Duty to preserve communications
• C. Duty to meet and confer
• D. Duty to disclose every potential witness

Answer: (A)

Rule 26(e) imposes the duty to supplement or correct disclosures or discovery responses when new information makes the earlier disclosure incomplete or inaccurate. After you make initial disclosures under Rule 26(a) or respond to discovery, you must update that information in a timely manner if things change or more details become known—adding witnesses, documents, or facts, or correcting prior statements. This keeps the record accurate and helps prevent surprise at trial. Preservation of ESI, meet-and-confer obligations, and disclosing every potential witness are governed by other rules or standards, not the supplementation duty of 26(e).
