Abstract
The regulations of the Notary Law of 14 February 1991, in force since 1 June 2024, aimed at preventing the negative consequences of so-called identity theft in real estate transactions, became the basis of significant dilemmas during the first months of their validity. These dilemmas frequently led to a reduction in the efficiency of legal transactions carried out with participation of a notary. The present article covers the most significant problems caused by the new provisions, together with a proposal for their resolution aimed at meeting the objectives of the amendment while maintaining the efficiency and certainty of real estate transactions. The second part of the study addresses the issues related to the entities whose PESEL numbers are subject to verification. It also discusses the timing of verification and the consequences of failing to comply with this obligation. Furthermore, the study presents conclusions regarding so-called optional PESEL number verification and the implications of the verification system’s unavailability for the procedures discussed in the article.
