The right to inherit is recognized in the Fundamental Law, the detailed substantive legal rules are laid down in the Seventh Book of the Civil Code. In recent years, the legislator has formulated rules of substantive succession in other legislation beyond our private law code (the Civil Code). According to the Registered Partnership Act, the rules applicable to the spouse apply mutatis mutandis to the registered partner, which means that the registered partner is also a legal heir. The special rules for the acquisition of ownership of agricultural and forestry land by succession by will are laid down in the Land Traffic Act (Act CXXII of 2013). On 1 January 2023, a new law will enter into force (Act CXLIII of 2021), which will supplement the succession law provisions of the Civil Code in the case of joint legal intestate succession of undivided common ownership of agricultural land by several heirs. The designation of a public body to represent the State in succession matters is provided for in a separate ministerial decree. The present article analyzes how all these complex, fragmented regulations make it difficult to enforce the law and the extent to which it hinders the speedy execution of probate proceedings. The present article criticizes the fragmented regulation and proposes the integration of the rules of the separate laws into the Civil Code, as this could contribute to a more efficient application of the law.
