A wagering agreement is an agreement in which two persons agree that upon the happening or non-happening of an uncertain event, one person shall win and the other shall lose, and neither party has any real interest in the occurrence or non-occurrence of that event except the stake involved. The law relating to wagering agreements in India is primarily contained in Section 30 of the Indian Contract Act, 1872. The section declares wagering agreements to be void, subject to certain exceptions relating to horse-racing prizes. A wagering agreement is therefore different from an ordinary valid contract because the law does not enforce the rights arising from a wager. The essential feature of a wager is the existence of an uncertain event. The parties must be uncertain about the result of the event when the agreement is made. The event may be uncertain because it is yet to happen, or because it is uncertain whether a past event actually happened. For example, if A agrees to pay B ₹1,000 if a particular cricket team wins a match, while B agrees to pay A ₹1,000 if the team loses, the agreement is a wager because the parties' rights depend entirely upon an uncertain event. Another important element is that the parties must have a mutual chance of gain or loss. Each party must stand to win or lose according to the result of the uncertain event. If only one party can gain while the other has no possibility of loss, the agreement may not constitute a wager. Thus, mutuality of gain and loss is an important characteristic. The parties should have no genuine interest in the occurrence or non-occurrence of the event other than the possibility of winning or losing the stake. If a person has a substantial interest in the event independent of the wager, the agreement may not be regarded as wagering. For example, an insurance contract is not ordinarily a wagering agreement because the insured has an insurable interest in the subject matter. The insured seeks protection against
