New Rules of Servicing: Legal Access, Regularization and Changes After Law 21.458

In the dynamic world of rural development and land sales, clear and enforceable legal access has become decisive. Following multiple disputes over sloppy lot divisions and the rise of so-called "pleasure plots," new regulations now clarify and bind transit servitudes. This article explains the current legal regime, the requirements for constituting servitudes, and the concrete impact of Law No. 21.458 on the subdivision of rustic lands.

What is a transit servitude and when does it exist legally?

A predial servitude is a real right that burdens one property for the benefit of another: the dominant estate benefits from a right over the servient estate, for example to pass through it. This right is not automatic; it requires a constitutive title and registration in the real estate conservator (CBR) to be enforceable against third parties.

Therefore, even if a path has been used historically, without a registrable title and inscription there is no legal servitude. Article 882 of the Civil Code requires title for discontinuous servitudes such as transit: immemorial use or mere tolerance alone is insufficient.

How is the existence of a servitude verified?

The most reliable measure is to request a Certificate of Mortgages and Liens (Certificado de Hipotecas y Gravámenes) for the servient property at the CBR. That certificate shows whether a servitude is registered. If it does not appear there, it does not exist legally against third parties. In practice: "What is not registered is not worth against third parties."

Legal options if there is no registered servitude

When a property lacks formal access, several legal alternatives are available:

1. Conventional constitution: the parties may agree to establish a transit servitude. The agreement must be translated into a public deed and then registered with the CBR; a plan with coordinates and layout is mandatory.
2. Declaratory or recognition judgment: when there is supporting background (an old title or long use), a court may declare the servitude. The judgment must produce a registrable title to be effective against third parties.
3. Action for compulsory servitude (art. 847 CC): if a property lacks access to a public road, the owner may request the constitution of a legal transit servitude, with financial compensation to the servient owner. That servitude must also be registered.
4. Protective measures: precautionary relief can prevent arbitrary cuts to access and restore provisional access. Such measures do not themselves create permanent rights or generate registration, but they can preserve access while the dispute is resolved.

Law 21.458: New regulations for rural subdivisions

Promulgated on 20 July 2022, Act No. 21.458 introduces key changes to Decree Law No. 3.516, which regulates the subdivision of rustic lands. Its objective is to ensure that each resulting lot has legal and secure access.

Main changes:

• Compulsory access to public or agricultural roads for resulting lots.
• Interior roads (shared access routes) must be maintained pro rata by the owners.
• Roads projected on plans certified by the Agricultural and Livestock Service (SAG) are understood as automatic transit servitudes.
• Obligation to register these servitudes with the CBR.

The law ends informality in access: use or tolerance is no longer sufficient. Each subdivision must provide and formalize legal access, especially when a lot does not directly connect to a public road.

Regularization and considerations when buying

For rural buyers, verifying registered legal access is essential. The servitude should appear in the property's inscriptions; otherwise the buyer should require its formalization as a condition of the purchase.

For developers and subdividers, the process now requires more planning and documentation:

1. Include the road in the plan certified by the SAG.
2. Register the servitude with the real estate conservator (CBR).
3. Ensure proportional maintenance obligations among owners are established.

Owners of older lots without formal access may benefit from the regularization procedure established by Act No. 21.234, which was extended until 2030 by Act No. 21.477.

Expert views and oversight

Legal firms such as Dentons and Fontaine & Cia have noted that the reforms increase legal certainty and help avoid future conflicts. Jaime Mayor (Idealex) emphasizes that vehicle access must now be registered and maintained proportionally.

The Agricultural and Livestock Service (SAG) plays a central role: it certifies subdivisions, requires plans showing legal access, and may suspend processes if it detects irregularities. The Comptroller's Office has reaffirmed its oversight powers in this area.

Legal security for rural development

Current legislation, reinforced by Act No. 21.458, seeks to professionalize and regularize rural land development. Transit servitudes are now a central component of subdivision planning rather than an optional formality.

To avoid legal problems and protect your investment, always confirm that a lot has registered legal access. If you plan to subdivide, design the route and record the servitude from the outset. In a market where connectivity and legal certainty are increasingly valued, compliance is both an obligation and a competitive advantage.
