Business law establishes rules to govern business relationships and resolve disputes. The key Indian business laws include the Contract Act, Sale of Goods Act, Partnership Act, Negotiable Instruments Act, and Companies Act. For a contract to be valid, it requires offer and acceptance, lawful consideration, capacity of parties, lawful object, and intention to create legal relationship. A minor's agreements are void as a minor lacks contractual capacity. However, a minor can be a beneficiary or promisee and is not liable for torts directly connected to a void contract.
