Public Property in Brazil: Classification and Applicable Legal Regime

Government property is governed by its own set of rules. These rules restrict its availability, condition its use by private parties, and impose different obligations depending on the purpose of each asset. Understanding this classification is essential for administrative contracts, concessions, usucapião (acquisition of ownership through long-term possession, comparable to adverse possession) actions, and determining the State’s civil liability.

The Classic Three-Part Division of Public Property

Articles 98 to 103 of the Civil Code divide public property into three categories: property for the common use of the people (bens de uso comum do povo), property for special use (bens de uso especial), and dominical property (bens dominicais), meaning property the State holds in its private capacity. This division, endorsed by Brazilian administrative law scholars, determines the legal regime for each type. It also defines when property may be sold, encumbered, or used by third parties.

Property for the common use of the people is intended for general use by the community, and no government authorization is required for ordinary access. Rivers, seas, roads, streets, and public squares belong to this category. The State holds public ownership but not exclusive use, because title is directed permanently and without restriction to a collective purpose.

Property for special use includes buildings and land assigned to a federal, state, territorial, or municipal service or establishment, including those of their autarquias (autonomous public agencies). Courthouses, public schools, hospitals in the public system, and administrative offices are examples. Here, private use depends on a concession or permit granted by the competent public authority.

Dominical Property and Its Unique Legal Position

Dominical property, also called domainal property or the State’s private domain, is not assigned to any specific public purpose. This category includes terras devolutas (vacant public lands), decommissioned buildings, receivables owed to the government, and negotiable securities held by public-law entities. What sets it apart is that it is subject, to a greater extent, to private-law rules, without entirely losing its public-law regime.

The practical importance of this distinction lies in the possibility of sale. Only dominical property may be transferred by the State to private parties, and only if the legal formalities are met, including prior release from public use, appraisal, and public bidding (licitação). Property for common use and for special use cannot be sold while it remains dedicated to its public purpose. The law prohibits it.

Features of the Public-Law Regime

The legal regime for public property rests on four essential attributes: inalienability (in a relative form, with exceptions for dominical property), immunity from attachment, immunity from acquisition through prescription, and freedom from encumbrances. These attributes exist to protect property dedicated to the public interest, so that private obligations cannot reach assets essential to providing collective services.

Dedication turns an asset into an instrument of the public interest; release returns it to legal commerce. Neither takes effect without a formal act by the public authority.

Immunity from acquisition through prescription (imprescritibilidade) deserves special attention in the context of usucapião. The Supreme Federal Court and the Superior Court of Justice have established that public property of any category cannot be acquired through usucapião. This bar is reinforced by Article 183, paragraph 3, and the sole paragraph of Article 191, both of the Federal Constitution. The protection extends even to dominical property, a point that often causes disputes in the lower courts.

Immunity from attachment (impenhorabilidade), in turn, prevents creditors of the State from collecting their claims by directly seizing public assets. The constitutional mechanism of precatórios (court-ordered payment requisitions), provided for in Article 100 of the Federal Constitution, replaces attachment. It ensures payment in an orderly, continuous way without jeopardizing essential public services.

Dedication, Release, and Use by Private Parties

Dedication (afetação) is the legal act or event by which public property receives a specific purpose in the collective interest and becomes part of the State’s unavailable assets. Release (desafetação), the reverse process, removes that purpose, converts the property into dominical property, and opens the way to a possible sale, provided the formalities of prior appraisal and public bidding are met. Either one may result from a statute, an administrative act, or a legal event, such as the prolonged abandonment of a public square or the opening of a new headquarters for a public agency.

Private parties may use public property through an authorization of use (a revocable, discretionary act), a permit of use (also revocable, but formalized in a bilateral administrative act), or a concession of use (contractual, with a fixed term and greater legal stability for the concessionaire). Each type carries a different degree of stability and a different right to compensation if the granting authority revokes it unilaterally.

The concession of real right of use (concessão de direito real de uso), governed by Decree-Law 271/1967, gives a private party a defeasible real right over public property. That right can pass by inheritance and can be recorded at the real estate registry office. It differs from an ordinary concession because it creates a real-property bond enforceable against third parties. It has been widely used in housing programs and urban land title regularization procedures.

Frequently Asked Questions

Can you acquire public property through usucapião?

No. The Federal Constitution expressly prohibits usucapião of public property, and the ban covers every category, including dominical property. The Supreme Federal Court and the Superior Court of Justice are settled on this point. There is no exception based on length of possession, the type of usucapião claimed, or the alleged failure of the public authority to reclaim the property.

What is the difference between dedication and release of public property?

Dedication is the act by which public property is assigned to a collective purpose, making it inalienable for as long as that purpose lasts. Release is the reverse process: it removes the public purpose, converts the property into dominical property, and opens the way to a possible sale. Neither happens automatically. Both require a formal act by the public authority, either a statute or a reasoned administrative act.

Is property of autarquias and public foundations subject to the same regime as State property?

Yes. Property of autarquias and of public foundations governed by public law falls under the legal regime for public property, with the attributes of relative inalienability, immunity from attachment, and immunity from acquisition through prescription. The nature of the legal entity is decisive. Private-law entities within the indirect public administration, such as state-owned companies and mixed-capital companies, hold their property under a predominantly private regime. The exception is property directly dedicated to providing an essential public service.
