When do new rules of FRCP go into effect?

• A. January 1
• B. July 4
• C. May 15
• D. December 1

Answer: (D)

New FRCP amendments have a default effective date: December 1. This timing is the standard when the Supreme Court approves changes and they pass through the required review process. The December 1 date provides a predictable annual switch for the federal rules, helping courts and practitioners know when the new rules apply. Of course, if a particular amendment specifies a different date or Congress rejects the amendments, those provisions override the default. So December 1 is the best answer because it is the usual, stated baseline for when new FRCP rules take effect.
