For many people, the idea of having a vacation home in a sought-after place like the coast, with all maintenance costs and taxes, may seem like a distant dream. Multiproperty, although it already existed as a shared property model, generated legal uncertainties before specific legislation.
The multiproperty law (Law No. 13.777/18) marked a turning point by providing a secure and transparent environment for those seeking a practical and conscious way to enjoy incredible destinations. Continue reading to learn the key points of this legislation and how it protects your property rights.
What is the multiproperty law (Law No. 13.777/18)?
Law No. 13.777/18 was created to regulate and formalize the multiproperty regime in Brazil.
Understand what changed with the arrival of Law No. 13.777/18
The legislation amended the Civil Code and the Public Records Law, elevating multiproperty to the status of a real property right. This means that the multiproperty owner now has a solid legal guarantee over their fraction.
Unlike timeshare, the multiproperty law transforms use into real property, representing an important legal advancement.
How does the multiproperty law define the shared property model?
The multiproperty law, specifically in Article 1.358-C of the Civil Code, defines the regime as a type of condominium where each owner holds a fraction of time, ensuring the right to exclusive use of the property for a determined period each year.
In practice, this means that each buyer has an individual registry in the notary's office, proving ownership of their fraction. This legal definition was fundamental in granting security and credibility to the model.
The regime differs from the traditional condominium, where possession is continuous and shared. In multiproperty, exclusivity is temporal. During their period, the owner can use the property as if they were the sole owner.
It is also not a lease or lodging: the multiproperty owner is not a guest but a real property owner.
What is the objective of the multiproperty law?
The main objective of the multiproperty law is to fill a legal gap that existed in the Brazilian real estate market. By providing legal grounding to the regime, the legislation protects both purchasers and developers.
The law also establishes clear guidelines for management and conflict resolution. Before it, the absence of specific regulations generated uncertainty and disputes among co-owners.
To whom does the multiproperty law apply?
The multiproperty law applies to all developments adopting this regime in Brazil, including resorts, residential condominiums, and beach houses.
To be valid, multiproperty must be formally instituted through an instrument recorded in a notary's office. The legislation also governs relationships between co-owners, administrators, and third parties.
It is the multiproperty law that ensures the individual registry of the time fraction, securing property rights and distinguishing the model from other forms of sharing without equivalent legal protection.
What are the main points defined by the multiproperty law?
The right to the time fraction and exclusive use of the property
The law defines that each multiproperty owner is entitled to an annual time fraction, not less than seven days, which can be:
- Fixed, with use always on the same dates;
- Floating, allowing choice according to availability.
The right of use extends to the facilities, equipment, and furniture that accompany the property.
The indivisibility of the property
One of the pillars of the multiproperty law is the indivisibility of the property. It cannot be dissolved or divided by condominium action, ensuring legal stability for all co-owners.
The only possibility is the sale of the time fraction, maintaining the property as shared ownership.
The obligation of a professional administrator
The law requires that the multiproperty condominium be managed by a professional administrator, responsible for management, maintenance, reservations, and expense collection.
What are the rights and duties of the multiproperty owner according to the law?
Right to use, enjoy, and dispose of their time fraction
The multiproperty owner is entitled to the exclusive use of the property during their period, including facilities and furniture.
The legislation also guarantees the right to dispose of the fraction, allowing sale, transfer, donation, or inheritance, which reinforces the patrimonial nature of the model.
Duty to pay ordinary and extraordinary expenses
In return, the multiproperty owner must contribute with:
- Ordinary expenses (water, electricity, maintenance);
- Extraordinary expenses (renovations and improvements).
The apportionment is proportional to the time fraction, and default may result in suspension of the right of use until regularization.
Responsibility for furniture and facilities
The law assigns the user of the period the responsibility for the conservation of the property and goods. Damages are charged to the owner who used the space during the corresponding period.
How does the multiproperty law protect your property rights?
Guarantees legal security
With inclusion in the Civil Code, multiproperty became a real right, recorded in a notary's office and enforceable against third parties. This ensures that the fraction is linked to the owner's name, with legal protection equivalent to that of a traditional property.
Defines clear management rules
The requirement for a professional administrator and specific convention prevents amateur management and conflicts, ensuring adequate preservation of the assets.
Brings transparency among co-owners
The legislation defines voting rules, financial obligations, and decision-making in assemblies, strengthening trust and coexistence among owners.
