Short answer. It depends on which kind of land it is. Property the State holds for public use or public service cannot be sold or leased while it keeps that character. Everything else the State owns is patrimonial property, and patrimonial property can be disposed of much like private land.
What the law says
All other property of the State, which is not of the character stated in the preceding article, is patrimonial property.

The division the Civil Code draws
State property falls into two boxes. The first holds property of public dominion — roads, canals, rivers, shores, ports and public works, and land intended for public service or the development of national wealth. That property is outside commerce: it cannot be sold, cannot be validly leased for private appropriation, cannot be acquired by prescription, and cannot be seized by creditors. The second box is defined by exclusion, which is what this article does. Whatever the State owns that does not have that public character is patrimonial property, held by the government much as a private owner holds his own — and therefore capable of being sold, leased, mortgaged and, in principle, acquired by prescription.
Land does not move between boxes by itself
This is where most disputes begin. A parcel does not become patrimonial merely because it has been abandoned, unused for years, fenced off, occupied by settlers, or no longer needed for its original purpose. Non-use is not conversion. The land has to be taken out of public dominion by a positive act of the government declaring it no longer intended for public use or public service and available for disposition. Until that happens the parcel stays outside commerce, whatever the condition on the ground suggests. The practical consequence is blunt: occupying government land for decades does not, on its own, build a claim to it.
Why this matters to an ordinary buyer or occupant
If you are buying from a government agency, leasing a stall or a foreshore area, or applying to have long occupation recognized, the classification of the land is the first question, not a technicality raised at the end. A sale or lease of property of public dominion is not merely risky — it is void, and a void transaction cannot be cured by payment, by a receipt, by tax declarations, by improvements built in good faith, or by the passage of time. Buyers sometimes discover this only when they try to register, at which point the money is long spent.
What to check before committing
Ask for the document showing the land's present classification and the act, if any, that released it for disposition — not just the agency's willingness to transact. Verify what the title or survey actually covers, and whether the agency has authority to dispose of that particular parcel; owning land and being empowered to sell it are separate questions for a government body. Where the transaction runs through a public bidding or a specific disposition programme, the governing rules are found in that programme rather than in the Civil Code alone. Have the classification checked independently before any payment is made.
