Void Agreements (Sections 23-30) are contracts that create no legal obligations from inception. Reasons for voidness: (1) Illegality—object or consideration contrary to law; (2) Public policy—wagering agreements, agreements restraining marriage, trade or legal proceedings; (3) Uncertainty—terms so vague they cannot be enforced; (4) Impossible conditions—agreements with conditions incapable of performance. Wagering agreements (Section 30): Bets and wagers void as against public policy; exceptions apply to lawful sports/insurance. Difference: Void agreements have no legal effect; Voidable contracts exist but can be cancelled. Restraint of trade agreements (Section 27): Restraining person from earning livelihood generally void; reasonable restraints (non-compete in employment) may be valid. Marriage conditions: Agreements conditioning marriage on performance of act generally void. Agreements affecting legal proceedings: Ouster of jurisdiction void; reasonable settlement valid. Examination of case law: Chikhalal v. Minocher Homji establishes certainty requirement. For accountants, understanding void agreements critical when advising on contract validity; some non-compete clauses may be enforceable. Exam tip: Identify specific ground for voidness; distinguish void from voidable; explain public policy rationale.
