Faixa de Fronteira and Rural Land: When Foreigners Need Authorisation

A foreign buyer looks at a farm in Paraná, a lot near Foz do Iguaçu, or a stretch of pasture in Mato Grosso do Sul and asks a lawyer one question: do I need permission, and from whom? The honest answer starts with two classifications, not one. Is the land rural? Is it inside the 150 km border strip? Each “yes” brings its own statute, its own authority and its own consequence for a deed signed without approval — and the two regimes stack.

Get the classification wrong and the consequence is not a fine. Under Lei 5.709/1971, art. 15, an acquisition that violates the law is void; the notary and the registrar are liable; the seller must refund. In the border strip, Lei 6.634/1979 tells every authority and registrar to refuse the act without proof of assent. A buyer who has “closed” without the required authorisation has, in law, bought nothing.

This guide is educational content prepared by the ZS Advogados Associados real estate team for foreign nationals considering rural or border-region land in Brazil and the advisers helping them. It sets out the decision map — urban or rural, inside or outside the strip, individual or company, how many módulos — and the authority and procedure at each branch. It is deliberately narrower than our INCRA rural land guide, which covers INCRA’s cadastres, the CCIR, CAR and ITR; here the focus is the authorisation question itself. For the urban-versus-rural threshold see our comparison of urban and rural property for foreigners.

Why does the classification come first?

Because the statutes attach to categories of land, not to categories of buyer alone. A foreigner buying an urban apartment in a border city such as Foz do Iguaçu, Corumbá or Uruguaiana is, in general, outside both regimes: Lei 5.709/1971 covers rural property, and the border-strip acts that require assent for foreigners under Lei 6.634/1979, art. 2, V and VI, are transactions with rural property and participation in companies holding rural property. The same foreigner buying a small farm two kilometres outside that city is inside both.

One qualification belongs here rather than in a footnote. Lei 5.709/1971, art. 7, subjects to prior assent “the acquisition of property situated in an area considered indispensable to national security by a foreign person, natural or legal”, and Lei 6.634/1979, art. 1, declares the whole 150 km strip to be exactly such an area. Because the 1971 statute as a whole regulates the acquisition of rural property, art. 7 is read within that scope in practice. A foreign buyer of an urban unit in a border municipality should nonetheless have counsel confirm the position with the local registry before relying on the general rule.

Rural or urban is not a question of appearance. Brazilian law classifies by destination and by municipal perimeter: land inside the urban perimeter defined by municipal law is urban for property-tax purposes (IPTU), while land outside it — or inside but with rural use, under the destination test applied to the federal rural tax (ITR) — is rural. The property’s cadastral records (municipal for urban, INCRA’s SNCR and the CCIR for rural) and the description on the matrícula tell the story, and they should agree.

Inside or outside the strip is a question of measurement. Lei 6.634/1979, art. 1, defines the faixa de fronteira as the internal band 150 km wide, parallel to the land border line. The Constitution repeats it (art. 20, §2) and declares the strip fundamental to the defence of the territory. The federal government publishes lists of the municipalities wholly or partly within the strip; for a municipality only partly inside, the specific lot’s distance from the border decides.

Legal basis: Lei 5.709/1971, art. 1; Lei 6.634/1979, arts. 1–2; Constituição Federal art. 20, §2; Código Tributário Nacional arts. 29 and 32 (rural/urban for tax purposes); Lei 9.393/1996 (ITR) art. 1.

Who counts as “foreign” under Lei 5.709/1971?

The statute names three groups, and the third is the one that surprises buyers structuring through a company.

1. The foreign individual resident in Brazil (art. 1, caput). The statute’s own title and opening article are written for the estrangeiro residente no País. INCRA’s Instrução Normativa 88/2017 — the instruction in force, published on 13 December 2017, which revoked IN 76/2013 and had its art. 28 amended in December 2018 — is described by INCRA itself as governing acquisition and lease “by a foreign natural person resident in the country” and by foreign or foreign-controlled legal entities. Neither the statute nor the instruction provides a route for a non-resident individual to acquire rural land in their own name. A non-resident should therefore treat direct acquisition of rural land as a matter for specific analysis rather than as available by default.

2. The foreign legal entity authorised to operate in Brazil (art. 1, caput; art. 5). Such a company may acquire rural land only for agricultural, livestock, industrial or colonisation projects tied to its corporate purpose, with INCRA approval of the project.

3. The Brazilian company under foreign control (art. 1, §1). A Brazilian company is subject to the same regime when foreign individuals or entities that reside or have their seat abroad hold, at any title, the majority of its share capital. INCRA publishes, among the normative material on this subject, the Parecer CGU/AGU nº 01/2008-RVJ, approved on 23 August 2010, which concluded that art. 1, §1, was received by the 1988 Constitution — in its original wording and after Constitutional Amendment 6/1995. That is the reading INCRA and the registries apply.

The border-strip statute is broader still. Lei 6.634/1979, art. 2, VI, requires CDN assent for the participation, at any title, of a foreigner — individual or company — in a company holding a real right over rural land in the strip. There is no majority threshold; a minority foreign shareholder in a farm-holding company in the strip triggers the requirement.

Legal basis: Lei 5.709/1971, arts. 1 and 5; Decreto 74.965/1974, arts. 1 and 11; Parecer AGU LA-01/2010; Lei 6.634/1979, art. 2, VI; Lei 8.629/1993, art. 23 (leases by foreigners subject to the same limits).

Speak to counsel — corporate structures are the contested ground. Whether a given structure is “foreign” under the 1971 statute and whether a given stake triggers the 1979 assent are questions that turn on the cap table, the residence of the shareholders and the location of the land.

How much rural land can a foreign individual acquire?

The unit is the módulo de exploração indefinida (MEI), a regional measure INCRA fixes for each zone by type of land use; it can range from a few hectares in intensively farmed regions to a hundred in the Amazon. Decreto 74.965/1974, art. 7, sets the tiers for foreign individuals.

Area (in MEI)	Rule	Source
Up to 3 MEI	Free acquisition — no authorisation or licence, subject to the general requirements of law	Lei 5.709 art. 3 §1; Decreto 74.965 art. 7 §1
More than one property of up to 3 MEI each	Authorisation required — the exemption cannot be multiplied	Decreto 74.965 art. 7 §3
Above 3 and up to 20 MEI	INCRA authorisation required	Decreto 74.965 art. 7 §2
Above 20 and up to 50 MEI	INCRA authorisation conditioned on approval of an exploitation project	Decreto 74.965 art. 7 §4
Above 50 MEI	Not permitted for a foreign individual, unless the President raises the limit after hearing the CDN	Lei 5.709 art. 3 caput and §3

Two further limits apply at municipal level regardless of the individual’s own holding.

• The one-quarter cap. The sum of rural areas belonging to foreign individuals and entities may not exceed one quarter of the surface area of the municipality, proven by a certificate from the Registro de Imóveis based on the special register the registry must keep (Lei 5.709, arts. 10 and 12).
• The nationality sub-cap. Persons of the same nationality may not own, in each municipality, more than 40% of that quarter — in other words, 10% of the municipality (art. 12, §1).

Art. 12, §2, excludes three categories from these municipal caps: areas below 3 MEI; certain areas transacted and cadastred before 10 March 1969; and acquisitions where the buyer has a Brazilian child or is married to a Brazilian under the community-property regime. That last exclusion is frequently overstated in general guidance — it lifts the municipal caps, not the authorisation requirement or the individual ceiling. Before any deal above the free tier, the buyer’s counsel obtains the registry’s certificate of foreign holdings in the municipality; INCRA will refuse an authorisation that would breach either cap.

Legal basis: Lei 5.709/1971, arts. 3, 10 and 12; Decreto 74.965/1974, arts. 5 and 7.

What must a foreign company show?

A foreign company authorised to operate in Brazil, or a Brazilian company under foreign control resident abroad, may acquire rural land only for agricultural, livestock, industrial or colonisation projects linked to its corporate purpose, and the acquisition depends on approval of that project (Lei 5.709, art. 5; Decreto 74.965, arts. 11–12). The regulation routes the project to the competent federal body — INCRA for colonisation projects, the regional development authorities for agricultural and livestock projects in their areas, and the industry authority for industrial ones — with the federal agriculture authority approving. INCRA’s current guidance is blunter and more useful in practice: a legal entity, foreign or treated as foreign, must present an exploitation project whatever the size of the property. The application must document the total area of the municipality, the sum of foreign holdings there, and the project itself.

Above a certain scale, the decision leaves the agencies altogether. The Constitution provides that the law shall regulate and limit the acquisition or lease of rural property by foreign individuals and companies and shall establish the cases that depend on authorisation by the National Congress (art. 190). Lei 8.629/1993, art. 23, §2, supplies those cases: Congress must authorise both any acquisition or lease that exceeds the area and percentage limits of Lei 5.709/1971, and any acquisition or lease by a foreign legal entity of an area larger than 100 módulos de exploração indefinida. The same article’s caput confirms that a foreign resident individual and a company authorised to operate in Brazil may lease rural property only in the form of Lei 5.709/1971, with all of that statute’s limits, restrictions and conditions applying to the lease (§1).

In the border strip, a company that will hold rural land with any foreign participation additionally needs CDN assent (Lei 6.634, art. 2, VI), and companies pursuing the industrial and mineral activities listed in art. 2, III–IV, must meet the Brazilian-majority conditions of art. 3 (at least 51% Brazilian capital, two-thirds Brazilian workers, Brazilian majority in management).

Legal basis: Lei 5.709/1971, art. 5; Decreto 74.965/1974, arts. 11–12; Lei 6.634/1979, arts. 2 and 3.

What does the border strip add?

Lei 6.634/1979, art. 2, lists the acts that are prohibited in the strip without the prior assent of the National Security Council — read today as the Conselho de Defesa Nacional (CDN), the body the 1988 Constitution created in its place (art. 91). For a foreign buyer, two items are decisive:

• V — transactions with rural property that give a foreigner ownership, possession or any real right over it. This captures purchase, but also lease (arrendamento), usufruct, mortgage in the foreigner’s favour, and possession-based arrangements.
• VI — participation, at any title, of a foreigner, individual or company, in a company holding a real right over rural property. This captures the share purchase, the capital increase, the partner admission.

Art. 2, §4, in the wording given by Lei 13.986/2020, carves out security interests from both items V and VI: the constitution of a real guarantee — including the transfer of fiduciary ownership — in favour of a national or foreign legal entity, or of a national legal entity in which foreign persons holding the majority of its capital and resident or seated abroad participate at any title, and also the receipt of rural property in liquidation of a transaction with such an entity, whether through enforcement of the guarantee, dação em pagamento or any other form. Lei 5.709/1971, art. 1, §2, II and III, was amended in the same terms. The carve-out is drafted for legal entities engaged in credit transactions; it is not a route for a foreign individual to take rural land in the strip.

Which body actually grants the assent

This is where published guidance most often goes wrong, so it is worth stating precisely. The Conselho de Defesa Nacional grants the assent, through its Executive Secretariat. Three sources say so directly:

• Lei 6.634/1979, art. 4, in the wording given by Lei 14.004/2020, requires authorities, entities and public officials to demand proof of “the assent of the Conselho de Defesa Nacional” for any act the Law regulates (excepting the land transfers dealt with by Lei 10.304/2001). The original text referred to the Conselho de Segurança Nacional, and art. 2, §1, still does; the 2020 amendment settled the successor question in the statute itself.
• Decreto 85.064/1980, art. 2, in the wording given by Decreto 11.076/2022, provides that the prior assent “shall be formalised by an act of the Executive Secretariat of the Conselho de Defesa Nacional”, published on an electronic site and notified to the interested federal body and, in the case it specifies, to the applicant. Modification or revocation follows the same form.
• INCRA’s own guidance on the acquisition of land by foreigners states that all properties in the border strip or in an area considered one of national security require the prior assent of the Conselho de Defesa Nacional (CDN).

The CDN is a constitutional body (Constitution, art. 91) and its collegiate structure and Executive Secretariat sit within the Gabinete de Segurança Institucional (GSI) of the Presidency, which publishes the current documentary requirements. The CDIF — the standing commission for the development and integration of the border strip — is a different body with a development-policy remit; it does not grant the assent, and guidance that names it as the authorising body for a land purchase is wrong.

A refusal, modification or revocation may be appealed to the President of the Republic (art. 2, §2), and the application must carry the opinion of the federal body that controls the activity (§3) — for rural land, INCRA.

Every public authority and registrar must demand proof of the assent before performing any act the statute regulates (art. 4). A notary who draws a deed, or a registrar who registers it, without the assent is acting outside the law. Where a company holds rural land in the strip and takes foreign participation without the assent, Decreto 85.064/1980, art. 34, §2, exposes it to dissolution.

For rural land, the two regimes are tied together at the procedural level. Decreto 74.965/1974, art. 10, provides that INCRA, when granting its authorisation, first hears the Council’s secretariat where the property lies in an area indispensable to national security. Decreto 85.064/1980, arts. 29 and 33, come at it from the other side: for rural-property transactions in the strip involving foreigners, the process begins at INCRA, which forwards the file to the Council’s secretariat with its opinion, and the file returns to INCRA once considered. In practice a single dossier feeds both decisions, and the buyer’s counsel prepares it once.

Legal basis: Lei 6.634/1979, arts. 1–4 and art. 2 §§1–4 (art. 4 in the wording of Lei 14.004/2020; §4 in the wording of Lei 13.986/2020); Decreto 85.064/1980, arts. 2, 29, 33 and 34 (art. 2 in the wording of Decreto 11.076/2022); Constituição Federal art. 91 (CDN); Lei 5.709/1971, arts. 1 §2 and 7; Decreto 74.965/1974, arts. 2 and 10.

The decision map

The questions below, taken in order, place almost any proposed purchase on the map.

Step	Question	If yes	If no
1	Is the property rural (outside the urban perimeter or with rural destination)?	Go to 2	Urban: in general neither regime applies on nationality grounds; standard due diligence, with the art. 7 point above confirmed locally in a border municipality
2	Is the buyer a foreign individual, a foreign company, or a Brazilian company under foreign majority control resident abroad?	Go to 3	Brazilian buyer: Lei 5.709 does not apply
3	Is the property inside the 150 km faixa de fronteira?	INCRA authorisation and CDN assent, for any real right, possession, or company stake (Lei 6.634 art. 2, V–VI)	Go to 4
4	Is the buyer an individual with a single property of up to 3 MEI?	Free acquisition (Lei 5.709 art. 3 §1) — but confirm no other rural holdings	Go to 5
5	Is the area above 3 and up to 50 MEI (individual)?	INCRA authorisation; exploitation project above 20 MEI	Above 50 MEI: not permitted for an individual
6	Is the buyer a company?	INCRA approval of a project tied to the corporate purpose (art. 5)	—
7	Do the municipal caps (one quarter; 40% per nationality) leave room?	Proceed	Authorisation will be refused

The map has one corner that catches sophisticated buyers: a foreign minority stake in a Brazilian company that holds rural land in the strip. Lei 5.709 may not bite (no foreign majority), but Lei 6.634, art. 2, VI, does — any participation, at any title. Corporate structuring in the strip is not a way around the CDN.

What does the procedure look like in practice?

For a purchase above the free tier, the sequence commonly runs as follows. The steps are the statute’s; the timing is the agency’s.

1. Classify the land — rural or urban; inside or outside the strip; area in MEI for the zone (INCRA publishes the module values).
2. Pull the registry’s certificate of foreign holdings in the municipality (Lei 5.709, arts. 10 and 12) to test the caps.
3. Prepare the application to INCRA under Decreto 74.965, art. 9, declaring existing rural holdings, whether the caps are respected, and — above 20 MEI for an individual, or for any company acquisition — the exploitation project. INCRA’s Instrução Normativa 88/2017 lists the documents.
4. Where the land is in the strip, the process begins at INCRA and the file goes on to the CDN’s Executive Secretariat for the assent, carrying INCRA’s opinion, then returns (Lei 6.634, art. 2, §3; Decreto 85.064/1980, arts. 29 and 33). For a foreign individual, Decreto 85.064, art. 31, adds a specific list: a copy of the foreigner’s identity document, a declaration that the applicant is not the subject of a criminal inquiry or proceeding and has not been convicted at home or in Brazil, proof of ownership of the property including its chain of title, and a copy of the current INCRA registration certificate.
5. Contract conditionally. The purchase agreement should make the authorisation (and the assent) a condition, allocate the risk of refusal or delay, and avoid transferring possession before approval — possession is itself a listed act in the strip.
6. Deed by public instrument, inside a short window. For any acquisition of rural land by a foreigner the public deed is of the essence of the act (Lei 5.709, art. 8), and the deed must recite the authorisation, the buyer’s identity and residence documents and the INCRA data (art. 9; Decreto 74.965, art. 10). The regulation gives the authorisation a validity of 30 days, within which the deed must be drawn, followed by entry at the property registry within 15 days (Decreto 74.965, art. 10, sole paragraph). Closings are scheduled around that window, not the other way round.
7. Registration. The Registro de Imóveis registers the deed, enters the acquisition in its special register of foreign holdings (art. 10) and reports quarterly to the state judiciary’s oversight body and to the federal agriculture authority — INCRA in practice — with a further copy to the Council’s secretariat where the property is in an area indispensable to national security (art. 11).

Where the buyer is a non-resident individual, the position at step 3 needs separate analysis before the file is opened, as discussed above.

Legal basis: Lei 5.709/1971, arts. 8–11; Decreto 74.965/1974, arts. 9–10 and 15–16; INCRA Instrução Normativa 88/2017; Lei 6.634/1979, art. 2 §3; Decreto 85.064/1980.

Speak to counsel — timing is the agency’s, not the contract’s. No statutory deadline binds the outcome. A purchase agreement should be built around that fact.

What about titles already in the strip — Lei 13.178/2015?

A separate problem in the border strip is historical. Over decades, several states issued titles to rural land in the strip that was, in law, federal (public land in the strip is presumptively the Union’s — Decreto-Lei 9.760/1946, art. 5). Lei 13.178/2015 created the mechanism to ratify the registrations of those state-issued titles. Its structure turns on one threshold, measured in módulos fiscais rather than in the MEI used above:

Registration	What the Law does	Source
Up to 15 módulos fiscais, inscribed at the registry by 23 October 2015	Ratified by force of the Law itself, except where the Union is contesting the title administratively or judicially, or the land is subject to an agrarian-reform expropriation action filed by that date	Lei 13.178/2015, art. 1
Above 15 módulos fiscais	Ratified only if the interested party obtains georeferencing certification (Lei 6.015/1973, art. 176 §§3 and 5) and updates the property’s inscription in the national rural cadastre	art. 2, caput
Deadline to apply for those two steps	15 years from the Law’s publication — the period set by Lei 15.206/2025, after earlier extensions from four to ten years	art. 2, §2
Decision	The federal body must decide within two years; there is no ratification by lapse of time	art. 2, §§3–4
If nothing is applied for, or ratification is impossible	The federal body must ask the registry to register the property in the Union’s name	art. 2, §5
Above 2,500 hectares	Ratification additionally requires approval by the National Congress (Constitution, art. 188, §1)	art. 2, §6

Where a ratified registration overlaps another private title, the ratification does not decide which right prevails (art. 1, §1). Planalto’s official text also carries a note that the Law is the subject of a direct action of unconstitutionality (ADI 5623), so its standing should be checked at the time of the transaction.

A buyer of rural land in the strip should ask whether the seller’s chain of title rests on a state grant and, if so, whether ratification has been completed — because an unratified state title in the strip is a defective title irrespective of the buyer’s nationality.

Legal basis: Lei 13.178/2015, arts. 1–3 (art. 1, I in the wording of Lei 14.177/2021; art. 2, §2 in the wording of Lei 15.206/2025); Constituição Federal art. 188, §1; Decreto-Lei 9.760/1946, art. 5.

What are the consequences of getting it wrong?

They are severe by design.

• Nullity. An acquisition of rural land that violates Lei 5.709/1971 is void as a matter of law (art. 15). There is no cure by later authorisation; the act has to be redone.
• Liability of the notary and registrar. Both answer civilly for the damage they cause and may face criminal liability (art. 15).
• Refund by the seller. The seller must return the price (art. 15) — a remedy only as good as the seller’s solvency.
• Refusal of the act. In the strip, every authority and registrar must demand proof of the assent (Lei 6.634, art. 4). A deed presented without it should be refused; one registered by error is vulnerable.
• Straw-buyer arrangements. Using a Brazilian nominee (laranja) to hold rural land for a foreigner is a simulation under the Civil Code and exposes both parties; it also leaves the foreigner without any enforceable right against the nominee.

“The rural-land and border-strip rules are old, and buyers sometimes assume they are dormant. They are not. Registrars keep the special register, report quarterly, and refuse deeds that lack the authorisation. The two questions to answer before falling in love with a piece of land are whether it is rural and whether it is within 150 kilometres of a border. Everything else follows from those two answers.” — Zachariah Zagol, Attorney — OAB/SP 351.356 (educational comment).

An illustrative scenario

Hypothetical illustration — not a real client.

Consider a fictional, composite example built only to show how the pieces connect. Imagine a foreign investor who has lived in Brazil for several years and wants to buy a 180-hectare cattle property in a municipality in the west of Paraná. A friend suggests holding it through a Brazilian company in which the investor would have 40% and a Brazilian partner 60%, “so that the foreign-land rules do not apply”.

Counsel classifies the land first. It is rural. The municipality lies within 150 km of the Paraguayan border, so the property is in the faixa de fronteira. In this zone the MEI is small, so 180 hectares is well above 3 MEI and — for a direct purchase by the investor — would need INCRA authorisation with an exploitation project. The company structure does not help: because the foreign stake is a minority, Lei 5.709’s company rule may not engage, but Lei 6.634, art. 2, VI, requires CDN assent for any foreign participation in a company holding a real right over rural land in the strip, and the plan to give the investor possession under a lease would itself be a listed act under item V. Counsel also finds that the seller’s title rests on a state grant from the 1970s whose registration was never ratified under Lei 13.178/2015. The parties restructure: the title is ratified first; the purchase is contracted subject to INCRA authorisation and CDN assent, with the file prepared once for both; no possession passes before approval; and the deed, when signed, recites the authorisations as the statute requires.

Every distinguishing detail here is invented. This example is purely illustrative; every real transaction turns on its own facts and requires individual analysis by a licensed professional. Nothing in this example predicts any outcome.

What are the most common mistakes?

• Classifying by appearance. A weekend property with a house on it can be rural; a farm inside an expanded urban perimeter can be urban. Use the cadastres and the matrícula.
• Assuming the strip is a list of towns. It is a 150 km measurement. A municipality partly inside the strip has lots on both sides of the line.
• Multiplying the 3-MEI exemption. A second property of up to 3 MEI requires authorisation (Decreto 74.965, art. 7, §3).
• Structuring around Lei 5.709 and walking into Lei 6.634. In the strip, any foreign participation in a land-holding company needs CDN assent.
• Transferring possession early. In the strip, possession by a foreigner is itself a listed act.
• Ignoring the municipal caps. The one-quarter and 40%-per-nationality caps can be exhausted in municipalities with established foreign farming communities.
• Skipping the ratification check. A state-issued title in the strip that was never ratified under Lei 13.178/2015 is a title problem before it is a nationality problem.
• Relying on a nominee. A laranja arrangement is void and leaves the foreigner unprotected.

• MEI (módulo de exploração indefinida) — INCRA’s regional unit of rural area used to set the thresholds in Lei 5.709/1971.
• Projeto de exploração — the exploitation project required above 20 MEI for individuals and for all company acquisitions.
• Livro auxiliar — the special register of foreign rural holdings the Registro de Imóveis must keep under Lei 5.709, art. 10.
• Ratificação (Lei 13.178/2015) — the procedure that validates registrations of state-issued titles to land in the strip.
• Laranja — a nominee holding land for another; a simulation under Brazilian law.

Key takeaways

• Two classifications decide everything: rural or urban, and inside or outside the 150 km strip. Urban property is outside both regimes on nationality grounds.
• Lei 5.709/1971 and Decreto 74.965/1974 govern rural land: individuals up to 3 MEI free, 3–50 MEI with INCRA authorisation (project above 20), 50 MEI ceiling; companies only for projects tied to their purpose; one quarter of the municipality and 40% per nationality caps.
• A Brazilian company under foreign majority control abroad is treated as foreign (art. 1, §1; AGU LA-01/2010).
• In the faixa de fronteira, Lei 6.634/1979, art. 2, V–VI requires CDN assent for any real right or possession by a foreigner over rural land and for any foreign stake in a company holding it — no majority threshold. The assent comes from the Conselho de Defesa Nacional through its Executive Secretariat, not from the CDIF.
• INCRA and the CDN act on one file that starts at INCRA; the public deed is of the essence, must recite the authorisations, and must be drawn within the authorisation’s 30-day validity.
• Breach means nullity, notary and registrar liability, and refund (Lei 5.709, art. 15; Lei 6.634, art. 4).
• Check the ratification status of state-issued titles in the strip under Lei 13.178/2015: up to 15 módulos fiscais it operates by force of law, above that it must be applied for, and above 2,500 hectares it needs congressional approval.
• Contract conditionally; never transfer possession before approval.

How ZS Advogados can help

Rural and border-strip acquisitions by foreigners are governed by statutes from 1971 and 1979 that are still applied to the letter by INCRA, the CDN and the registries. The work is to classify the land before the offer, test the municipal caps at the registry, decide whether the buyer’s structure is “foreign” under one statute and “foreign participation” under the other, and prepare a single authorisation file that both agencies can act on — with a purchase agreement built around the fact that the timing belongs to the agencies. Our real estate team runs that file for foreign buyers and can sign the deed by power of attorney once the authorisations are in hand. Our buying property in Brazil page explains the buy-side review, including the section on rural and border-zone land.

Practical prerequisites sit alongside the authorisations: the buyer needs a CPF before any of the acts above, and a power of attorney if the deed is to be signed without travelling. Our rural land ownership page sets out the buy-side review. Every parcel is different, and no general guide replaces individual analysis of the specific land, buyer and structure.

• Business law — corporate structures for agricultural investment and their treatment under both statutes
