Which concept involves a belief with no factual basis that influences the will?

• A. LAPSE (WILLS)
• B. Gifts to Children (WILLS)
• C. INSANE DELUSION (WILLS)
• D. UNDUE INFLUENCE (WILLS)

Answer: (C)

Insane delusion is a fixed, false belief with no factual basis that actually drives the testator’s dispositions. In a will, if a provision reflects the influence of such a delusion, the portion affected may be set aside because the testator’s act wasn’t grounded in reality or rational testamentary intent. This distinguishes it from undue influence, which involves external pressure by another person regardless of any false belief. Lapse concerns who survives the testator, and gifts to children are simply types of gifts, not tied to a belief-driven motive. So the idea described—believing something with no factual basis that guides the will—is insane delusion.
