The topic of this diploma paper will be the contracts on support for life and contracts on support until death. Firstly, an overview of the historical development of contract on support for life will be provided – its span of development, from the time it was classified as an inheritance contract in the decrees of the Inheritance Law, to the time when it was classified as a compulsory contract in the decrees of the Obligatory Relations Act in 2006. Up until 2006, when the Obligatory Relations Act came into force, the contract on support until death existed as an unnamed contract. In the thesis, a thorough analysis of definitions of both contracts will be given, and their core characteristics, as well as their differences, will be examined. A special emphasis will be put on the fundamental difference between the two contracts – the moment of the acquisition of assets. Furthermore, the matters of the form of the contract and its subject; rights and duties of both parties, and reasons and ways of rescission of the contracts will be thoroughly examined. The thesis will also address shortcomings of certain legal regulations. In order to allow for better understanding of the subject of the thesis, each element of the contract will be supported by examples from the legal practice. At the end of the thesis, an overview of the current state of affairs, issues and their potential solutions, which could bring about the development of the contract, will be provided.
