In the article, the author discusses the phenomenon of using contract templates based on English law in another legal system. Using the example of the use of English templates in Polish contract practice, the author argues that this constitutes a legal transplant, which phenomenon is one of the elements characteristic of hybridisation of law. The author further points out that within the framework of the use of model contracts of a given type, sui generis subsystems are formed, in which subsystems the interpretation of contractual provisions is not only based on a system other than the law which governs the contract, but also specific to this subsystem.
