Does it matter if you failed to raise a defense because you did not realize you had it?

• A. Sometimes
• B. No; ignorance is no excuse and you may waive it
• C. Yes
• D. Not relevant

Answer: (B)

Not raising a defense because you didn’t realize you had it is a waiver issue. In civil procedure, you must plead all defenses you intend to rely on in your responsive pleading. If a defense isn’t raised, you can lose the right to argue it later—even if you later discover you had a valid defense. Ignorance of the defense isn’t a legal excuse to avoid that rule; the system expects you to raise defenses you have, or risk waiving them. There are narrow exceptions for some defenses that can be raised later, but the general rule is that failure to plead can forfeit the defense. That’s why the correct answer is that it matters in the sense that you can waive the defense by not raising it.
