This paper briefly addresses the issue of public records, especially with regard to real estate and the validity of constitutional and infra-constitutional norms that regulate the right to property in the face of fraud and execution.

It provides a view of the constitutional guarantees that affect the right to property, demonstrating the non-compliance with these rules by operators of the law that end up harming third parties in good faith who, even though, enjoy the right to property, legal certainty and have improved the legal act , by mere misunderstanding, see their property expropriated.

What is the legal purpose of the public registry and what is its purpose is questioned. It demonstrates the Germanic property acquisition system, whose model gave soul to the Brazilian system, where the former is perfect and the latter is flawed, while one makes the acquired property untouchable and the other allows judicial constriction due to a gap left by the legislator

Although the new enforcement law narrows this gap, it continues to exist causing legal uncertainty, directly affronting the fundamental rights provided for by the federal constitution of 1988 and, consequently, causing legal uncertainty in the acquisition of real state.
