Third party to lease payments and payments on behalf of a third act both for the theoretical circle, or judicial practice, the law is a new application. China"fs "gContract Law,"h the 65th article of the third party to perform the contract payment the liability method, but not on behalf of third party payment contract for clearly defined, and legal theorists have not systematically on this issue and China, Chinese law, subrogation, subrogate, payment by subrogation, performance by subrogation, third-party payment, debt transfer, guarantee, accountability relatively complete study and comb.
