The article deals with a specific type of contract that an heir is entitled to conclude—the transfer (or sale) of the rights of succession. As a starting point, the author of the article analyses the formation and further development of the transfer of succession as a whole (hereditas) in the Roman law. Two major proceedings used by Roman lawyers for the purposes of the alienation of hereditas are analysed, one being in iure cessio hereditatis and the second taking the (...) form of emptio venditi hereditatis. The interrelations between this kind of transfer and the recognition of the possibility of the assignment of rights (cessio) under the Roman law are pointed out. The author traces the impact of the principles developed by the Roman law on the legal regulation of the contract in question in modern codification by drawing attention to the French Civil Code and the Civil Code of Quebec. The author states that the legal rules on the sale of the rights of succession contained in the new Lithuanian Civil Code adopted in 2000 have been transposed, to a large extent, from the two abovementioned codes. After analysing the object of this contract, the author concludes that it is the sale of a certain incorporeal property (res incorporales) that is meant by the terms ‘succession’ (hereditas) or the ‘rights of succession’. This feature distinguishes the analysed contract from the ordinary contracts that an heir may conclude for the purposes of the alienation of specific objects making part of the succession. (shrink)
