This article examines the impact of artificial intelligence (AI) technologies on the fundamental constructs and principles of civil law. It analyzes key challenges associated with rethinking legal entities, liability, property rights, and transactions in the context of the increasing autonomy of algorithmic systems. It demonstrates that traditional civil law theories, particularly legal entity theories, require adaptation to regulate relations involving AI. The authors propose directions for the development of civil law doctrine and legislation aimed at the harmonization of technological progress and human rights protection.
