Contract Law

A contingent contract is one where performance depends on an uncertain future collateral event. The defining characteristic is that the contractual obligation is triggered by something that may or may not happen. This is valid and enforceable, distinguishing it from wagering contracts which are void under Indian law.

This is a contingent contract because A's obligation to pay depends on the uncertain future event of being able to go on a foreign tour. Unlike a wagering contract which involves pure chance without any legitimate interest, this contract appears to be based on A's actual plans and ability to travel. The event is uncertain but not a matter of pure chance or speculation.

Under the postal rule, acceptance is complete when posted, but revocation is only effective when it reaches the offeror. Y can revoke acceptance anytime before the acceptance letter reaches X, but not afterwards. This is because the acceptance is already legally effective upon posting, so revocation must be communicated before that moment to prevent contract formation.

Bailment uniquely involves delivery of goods without transfer of ownership, and consideration may be present (non-gratuitous bailment like hiring a locker) or absent (gratuitous bailment like lending a book to a friend). In sale contracts, consideration (price) is always essential. Option B is correct because bailment is the only contract type listed where consideration can be gratuitous. Option A is incorrect because sale always requires consideration, D is wrong because gratuitous bailment exists.

Expressed conditions (also called express terms) are those that parties explicitly agree upon and include in their contract through discussion, negotiation, and written or verbal agreement. Implied conditions (B) are those presumed by law to exist based on the nature of the contract or trade customs. Option A is correct because expressed conditions must be consciously agreed upon by parties, not merely presumed by law. Options C and D are incorrect.

An agency becomes irrevocable when coupled with interest, meaning the agent has a pre-existing interest in the subject matter, or when the agent has incurred personal liability. The timing matters - the interest must exist before or at agency creation, not after.

An unpaid seller loses lien rights by waiving them, when buyer/agent lawfully obtains possession, or through estoppel (conduct leading third parties to believe lien doesn't exist). All three circumstances independently terminate the right of lien.

The statement 'Undue influence involves physical force' is NOT correct - this is what the question asks for. Undue influence is psychological pressure exploiting relationship trust, while coercion DOES involve physical force. This distinction is fundamental in contract law.

A valid contract requires at least two distinct parties - there must be an offeror and an offeree. The statement 'One person can contract with himself' is legally impossible because you cannot offer to accept something from yourself - contract law requires two or more persons/parties to create a binding agreement.

Under the Indian Contract Act, 1872, wagering agreements (betting on uncertain events) are expressly void per Section 30. In contrast, contingent contracts - which depend on future uncertain events collaterally - are perfectly valid under Section 31. The key distinction is that contingent contracts have a legitimate interest element, unlike pure wagers.

Quasi-contracts are not true contracts at all - they're obligations imposed by law to prevent unjust enrichment. They don't arise from agreement (A is correct), they create monetary rights (B is correct), and they're available against specific persons, not the world at large (C is correct). Since all three statements accurately describe quasi-contracts, D is correct.

An agency relationship can form by express agreement (clear terms), implied agreement (conduct suggesting agency), by ratification (principal later approves agent's unauthorized acts), or by operation of law (court-appointed guardians, trustees of insolvent estates, etc.). Since all these methods are valid ways to create principal-agent relationships, D is correct.

An agency coupled with interest means the agent has a specific interest in the property/subject matter of the agency (like a pawnbroker or mortgagee). Unlike ordinary agencies, these special agencies DON'T terminate on the principal's death, insanity, or insolvency because the agent's interest is independent of the principal's continued existence. This makes D the correct answer.

A valid contract requires multiple elements to coexist: offer and acceptance (mutual assent), intention to create legal relations, capacity of parties (competency), lawful consideration, lawful object, free consent, and sometimes writing/witnesses. Since option A covers offer/acceptance, B covers intention (though oddly phrased), and C covers capacity - and all are essential - D is correct as ALL these elements must exist together for a valid contract.

Under Section 2(d) of the Indian Contract Act, 1872, consideration must move at the desire of the promisor. The consideration can come from the promisee or any other person (a 'stranger' to the consideration), but every person who is not a party to the contract is a 'stranger' to the contract itself. This principle distinguishes between who provides consideration and who can enforce the contract.
