Foreign acquisition and lease of rural real estate in Brazil.
Practice focused on the acquisition and lease of rural real estate by foreign persons or entities deemed foreign, governed by Brazilian Law 5,709/71 and the oversight regime of the National Institute for Colonization and Agrarian Reform (INCRA).
STF reaffirms the regime (April 2026).
On April 23, 2026, the Plenary of the Brazilian Supreme Court (STF) unanimously concluded the joint trial of the Claim of Non-Compliance with a Fundamental Precept No. 342 (ADPF 342), filed by the Brazilian Rural Society, and of Original Civil Action No. 2463 (ACO 2463), filed by the Union and by the National Institute for Colonization and Agrarian Reform (INCRA), holding that art. 1, § 1 of Law 5,709/71 was reaffirmed under the 1988 Constitution. Under that provision, Brazilian companies controlled by foreign capital remain deemed foreign for purposes of acquiring rural real estate — subject, therefore, to statutory area limits, prior INCRA authorization and, where applicable, Congressional authorization.
The Court held that the restriction finds direct constitutional footing in articles 172 and 190 of the Constitution, which authorize both the regulation of foreign capital and limitations on the acquisition of land by foreigners. With that decision, the Supreme Court settled, at the constitutional level, INCRA's oversight regime.
Weber Advogados contributed to the technical discussion preceding the judgment, submitting an amicus curiae brief in ADPF 342. The firm also advises on several related proceedings before INCRA, the AGU and the Federal Prosecutor's Office (MPF).
The Law 5,709/71 regime.
Brazilian Law 5,709, of October 7, 1971, governs the acquisition of rural real estate by foreign individuals resident in Brazil, by foreign legal entities authorized to operate in the country and — under the consolidated interpretation — by Brazilian companies in which a foreign person holds, by any title, the majority of share capital while residing or being headquartered abroad (the so-called entities deemed foreign).
The statute sets quantitative limits (measured in indefinite exploration modules (MEI)), municipality-level restrictions, the requirement of prior authorization from INCRA and, in specific cases, authorization by the Brazilian Congress. Under Law 8,629/93, the same regime also applies to the lease of rural land — not only to ownership transfers.
The matter is particularly relevant to foreign investors in agribusiness, foreign-owned funds, multinational groups operating through Brazilian subsidiaries and M&A transactions involving rural assets.
How the firm acts.
Prior opinions and structuring
Assessment of how Law 5,709/71 applies to the specific transaction — characterization of the acquirer or lessee as foreign (or deemed foreign), the applicable area limits and the relevant authorization scenarios.
Registry due diligence
Chain-of-title review, registry inspection, encumbrance analysis, identification of prior acquisitions made in violation of the statute and assessment of their impact on the contemplated transaction.
Engagement with INCRA and the Brazilian Congress
Assessment of the viability of administrative regularization before INCRA, representation throughout the evidentiary proceedings, coordination with related bodies (the National Defense Council, IBAMA, and the AGU where applicable), and — when statutorily required — the legislative authorization process.
Administrative litigation
Defense in inspections and challenges to registry records by INCRA, the Federal Prosecutor's Office (MPF), and the Judicial Inspectorates of the State Courts of Justice. Technical practice grounded in the firm's body of precedent and prior opinions on the matter.
Common questions.
Can a Brazilian company be treated as foreign?
Yes. Under Laws 5,709/71 and 8,629/93 and the AGU Binding Opinion LA-01/2010, a Brazilian company controlled by a foreign person, or with majority foreign capital, is deemed a foreign entity for purposes of the statute — subject to the same area limits and authorization regime.
Does the law also apply to leases?
Under article 23 of Law 8,629/93, and consistent with the AGU's current position (Opinion LA-01/2010), yes. The lease of rural real estate by a foreign person, or by a Brazilian entity deemed foreign, is subject to the same limits and authorization regime that govern acquisitions.
When is Congressional authorization required?
When the area exceeds 100 indefinite exploration modules (MEI). Transactions within that threshold do not require Congressional authorization but remain subject to INCRA authorization.
What happens in case of an irregular acquisition?
The transaction is void ab initio. Administrative liability attaches to the registry official who recorded the transfer without statutory authorization, and the registration may be cancelled in an INCRA administrative proceeding.
