The principle of a partnership is that participation in it is voluntary. In Roman law it was defined as a consensual contract, i.e. one based on an agreement between the parties (consensus). What should we do, however, when a partner we trusted when the contract was concluded introduces another partner? The answer provided by Roman law was very clear: Socii mei socius meus socius non est (the partner of my partner is not my partner). The consilium presented in the article is an interesting example of the application of the Roman principle of socius socii mei socius meus non est in 15th-century legal doctrine. It demonstrates the durability of the tradition of thinking about partnerships since ancient Times}, title={Zasada "wspólnik mojego wspólnika nie jest moim wspólnikiem" w pewnym konsylium Alexandra Tartagnusa}, keywords={societas, partnership, consilia, Alexander Tartagnus}, }
