1. A party alleging duress to vitiate a contract must prove real and serious threats, not merely fanciful or speculative fears. The caveat subscriptor rule applies to signed agreements and the burden is on the party seeking to escape the contract to prove duress or undue influence. 2. The characterization of an agreement depends on its substantive terms, not its title - an agreement containing profit-sharing provisions rather than interest rates and repayment terms is a joint venture, not a loan. 3. Ownership of goods in a sale transaction is determined by examining the totality of the documentary evidence, including invoices identifying the purchaser and written instructions regarding control and release of the goods. 4. Under Order 13 Rule 87, failure to join a party is not fatal where that party has no legitimate interest in the subject matter, and a party aware of proceedings who chooses not to seek joinder cannot later complain of non-joinder.
