Abstract
This article analyzes changes introduced under the Act of 15 January 2015 amending the Code of Civil Procedure and some other legal acts. These changes constitute the next step in the field of informatization of land and mortgage registers, which includes informatization of land and mortgage register proceedings. The analysis focuses on discussing issues relating to the fundamental change introduced in connection with informatization of those proceedings, which consists in imposing an obligation to initiate such proceedings via the ICT system on notaries, court bailiffs and heads of tax offices as executive authorities. The analysis covers in particular: the scope of obligations imposed in connection with electronic submissions for entry into a land and mortgage register and how they are to be executed with the use of the ICT system; regulation of the time of submission under the electronic proceedings, as well as changes relating to the institution of annotation in a land and mortgage register.
