The purpose of writing a scientific work is to study the regulation of the real estate market, the role of the notary in ensuring the protection of the rights of participants in civil turnover and the formation of proposals to expand the powers of the notary to certify real estate transactions. Examining the dynamics of litigation in relation to real estate objects, it is stated that a significant number of them, undoubtedly, arise due to the functioning of various kinds of fraudulent schemes when making the transactions in question. It is noted that in recent years, fraudulent schemes for the unauthorized use of electronic digital signatures for processing transactions have become widespread in the real estate market. Based on the analysis of judicial practice in cases of challenging registered rights to real estate, on invalidating contracts for the sale of residential premises, it was concluded that state registration cannot fully provide for cases of unfair actions in the field of real estate turnover. The best option to ensure the interests of the owners of rights to real estate when concluding transactions with it is notarization of the transaction. For this reason, the paper concludes that it is advisable to diversify the range of transactions, the notarization of which is most appropriate in modern conditions.
