OF MARRIAGE
An agreement in restraint of marriage of any person other than a minor is void (sec 26). Every person has the freedom to marry. A person is not bound by law to marry, but an agreement restraining a person not to marry is contrary to public policy and illegal and hence void.
2. UNCERTAIN AGREEMENTS
Section 29 provides that an agreement the meaning of which is not certain or capable of being made certain is void. If there is ambiguity in wording of contract, it is not possible to read the exact intention of the parties to the contract. Thus an agreement to sell at a concessional rate is void for uncertainity. Similarly, an agreement to pay rent in cash without the rate being definitely fixed is void for uncertainity.

WAGER & INSURANCE CONTRACTS A contract of insurance is not a wager though it is performable upon an uncertain event. It is so because the parties therein have an interest in the contract. But an insurance on the life of a person in which the insurer has no interest is void as being a wager.
