A party seeking to enforce a contract or a term thereof that is subject to a condition precedent must plead and prove that the condition precedent has been fulfilled. Where a verbal contract contains a conditional term (such as performance being dependent on availability of funds), and that condition is not fulfilled, the contract does not become perfecta in respect of that conditional term, and no claim for specific performance or damages can arise from the unfulfilled condition. Courts will not imply long-term obligations into oral contracts without clear evidence of such terms, whether through express agreement or established trade usage. Once goods are paid for and delivered under a contract, ownership passes to the purchaser, and there can be no breach regarding those goods unless other ongoing obligations are clearly established as terms of the contract.
