If a party quickly amends its answer to raise a waived defense under 12(h)(1), is the defense preserved?

• A. Yes
• B. No
• C. Only if the amendment is approved by the court
• D. Not applicable

Answer: (A)

The key idea is that some defenses under Rule 12 can be waived if not raised early, but a timely amendment to raise the waived defense preserves it. If a party realizes quickly that it forgot to raise a defense like lack of subject-matter jurisdiction, lack of personal jurisdiction, or improper venue, it can amend its answer to include that defense. Doing so before the case proceeds far preserves the defense for the court to consider, rather than having it permanently waived. Courts recognize this corrective amendment as a proper way to avoid procedural traps, as long as it’s done promptly and before substantive rulings on the merits.
