8. Void and Voidable Contracts — Bringing Unit II Together

Every post in this unit has used the words "void" and "voidable" for a different reason — a minor's agreement is void, a contract caused by undue influence is voidable, a wagering agreement is void, an uncertain agreement is void. This final post of the unit stops adding new topics and instead pins down exactly what those words mean, and — just as importantly — what happens to the money or property that already changed hands once a court applies them.

The Three Definitions

The Act defines three closely related but distinct terms, and exam answers regularly lose marks for treating them as interchangeable.

Void agreement — Section 2(g): an agreement not enforceable by law at all. It was never a contract in the full legal sense; there is nothing for either party to affirm or walk away from, because there was nothing binding to begin with.

Voidable contract — Section 2(i): an agreement that is enforceable by law at the option of one or more of the parties, but not at the option of the other(s). Until the party with the option chooses to avoid it, it remains a fully valid, binding contract.

Void contract — Section 2(j): a contract that was valid when it was made, but later ceases to be enforceable by law and becomes void. The moment of failure here is after formation, not at the start.

Void Agreement vs. Voidable Contract vs. Void Contract

What the Option-Holder Can Do — Section 19

Where consent was caused by coercion, fraud, or misrepresentation, Section 19 gives the wronged party a genuine choice, not just a right to walk away. They may rescind the contract entirely, or, if they'd rather keep the deal, they may insist that the contract be performed and that they be put in the position they would have been in if the representation made had actually been true. This second option matters — the law doesn't force a wronged party to give up a bargain they still want, just because it was obtained unfairly.

Undoing What's Already Happened — Sections 64 and 65

• Section 64: when a person at whose option a contract is voidable rescinds it, and has received any benefit under the contract from the other party, they must restore that benefit to the person from whom it was received
• Section 65: when an agreement is discovered to be void, or a contract becomes void, whoever received any advantage under it must restore it, or make compensation for it, to the person from whom they received it

• Sections 64 and 65 both aim at the same fairness principle — a party shouldn't keep a benefit received under an agreement that the law no longer treats as binding — but Section 64 is specifically about a party choosing to rescind a voidable contract, while Section 65 covers the broader set of agreements that turn out to be void or become void
• Remember Mohori Bibee from Post 2: restitution under these general principles is still refused to a minor specifically, because ordering it would let a party who knew of the minority achieve indirectly what the law refuses to let them do directly

A Practical Example

A trader agrees to supply a specific imported chemical to a manufacturer every month for two years, and the contract is perfectly valid when signed. Eight months in, a new central government regulation bans the import and sale of that chemical entirely. The contract was not void or voidable at formation — both parties had full capacity and gave free consent — but it becomes void the moment performance turns unlawful, under Section 2(j). Applying Section 65, if the manufacturer had already paid an advance for deliveries that never happened, the trader must return that advance, since he received an advantage under an agreement that has since become void.

Quick Revision Points

• Void agreement (Sec. 2(g)): never enforceable, from the start — minor's agreement, wagering agreement, uncertain agreement
• Voidable contract (Sec. 2(i)): valid until the option-holder avoids it — contracts caused by coercion, undue influence, fraud, or misrepresentation
• Void contract (Sec. 2(j)): valid at formation, becomes unenforceable later — for example, through a subsequent change in the law
• Section 19: the wronged party in a voidable contract can rescind, or affirm and insist on being put in the position promised
• Section 64: a party rescinding a voidable contract must restore any benefit received. Section 65: a party under an agreement that turns out void, or becomes void, must restore any advantage received — except, per Mohori Bibee, against a minor whose agreement was void from the start
