What is horizontal property division?

In short, horizontal property division is a method that allows a property to be split into different independent units. Its primary nature is that the sectioned elements share similar characteristics, such as gardens. Each owner holds a share in the common areas.

‍

What is a horizontal property deed?

It is a document issued by a notary public that formalizes the creation of this legal regime. Its content is highly detailed, as it describes the divisions, with an emphasis on common areas, rules of conduct, and ownership percentages.

‍

Regulations for horizontal property division

The legal provisions governing this shared regime are extensive; however, the Horizontal Property Act and urban planning regulations are the most significant. Likewise, owners must comply with the requirements of the Land Registry to operate in accordance with the law.

‍

Who is responsible for the horizontal property division?

‍

Lawyers and notaries are responsible for carrying out this procedure. Additionally, there are expert appraisers who will perform an appraisal to determine the total value of the property.

Architect or qualified technician

Their role is important, as after carrying out the corresponding measurements, they must issue a document detailing those results.

Notary

The lawyers you hire will file a document with a notary to be evaluated by a qualified professional. Subsequently, they will authorize the segmentation if all conditions established by law are met.

Property Registry

The Property Registry registers the corresponding deed so that the resulting properties have full legal effect against third parties and can be transferred individually.

Types of horizontal property division

There are different forms of this legal structure depending on the characteristics of the property and how the owners' spaces are organized.

Simple horizontal division

This is primarily applied to residential buildings where multiple independent dwellings share common areas, services, and facilities necessary for the operation of the complex.

Horizontal division of detached properties

Residential developments and single-family housing complexes are the primary settings where this type of partitionis applied. Unlike its counterpart, this is distinguished by the fact that each owner has an independent structure.

Complex horizontal division

This is intended for real estate projects that combine residences, offices, commercial premises, and apartments. This type of arrangement is uncommon due to its extremely high cost.

‍

Horizontal property division by property type

This legal act can be applied to different types of properties provided that the corresponding legal and urban planning conditions are met. For your convenience, we have outlined the most important variables below.

Residential buildings

This is the most common scenario and allows for individualizing dwellings within the same building so that they can be sold, inherited, or mortgaged independently.

Commercial premises

Both shopping centers and office buildings frequently utilize this regime to legally separate each unit or space intended for economic activities.

Parking garages

Individual parking spaces can be configured as independent private elements through a partition, which facilitates their individual transfer.

Offices

Properties intended for professional activities can be divided into independent offices or units with a proportional share in common areas.

Private residential communities

Many exclusive residential communities use this system to organize homes, sports facilities, gardens, and other spaces shared among property owners.

Difference between horizontal property division and property subdivision

It is common to confuse them, but both concepts are distinct. The former creates private units within a space subject to a common regime. The latter, however, divides the property into several independent parcels.

‍

Requirements

To carry out a proper subdivision, it is necessary to meet a series of legal, technical, and administrative requirements to ensure the validity of the process.

• Title deed. Ownership of the property must be verified through the corresponding land registry documentation.
• Technical project. In certain cases, a report or project prepared by a qualified professional is required.
• Urban planning complianceOperations must comply with municipal regulations and permitted usage conditions.
• Public deedThe incorporation must be formalized before a notary through the corresponding document.
• RegistrationThe deed must be registered to grant full legal effect to the new units.
• Licenses or authorizationsSome municipalities require specific permits, such as not having a reverse mortgage at the time of registration.

To ensure a proper procedure, these conditions must be met and all requirements documented. Doing so avoids legal issues and simplifies commercialization.

‍

Advantages

Participation offers multiple benefits for owners, as it provides an unparalleled increase in value. This is viewed favorably by developers and investors interested in diversifying their returns.

Greater ease of sale

Each resulting unit can be transferred independently, expanding sales possibilities and facilitating future real estate transactions.

Improved economic efficiency

Subdivision allows for maximizing the overall value of the property by marketing different spaces separately according to their specific characteristics.

Legal certainty

To ensure legal protection for all involved owners, it is essential to have land registry registration. Likewise, rights and obligations must be specified to rule out disputes.

‍

Disadvantages

Not everything is perfect, as there are drawbacks that can dim the appeal of this process. Below, we will show you the negative aspects of property partitions.

Associated costs

Professional, notary, registry, and administrative fees can represent a significant investment depending on the complexity of the project.

Regulatory limitations

Some properties have certain structural or geographical impossibilities for executing this legal instrument, for example, the size of the land.

Management of common elements

The existence of shared spaces requires the coordination of decisions, expenses, and responsibilities among multiple owners.

‍

‍

Examples

There are many ways to apply these types of legal structures. In practice, they can be applied to almost any type of property. Take a look at the main forms of implementation.

• Residential building. Each apartment has its own authority, allowing for independent decision-making regarding that specific property.
• Shopping center. The various retail units belong to different owners under a single community regime.
• Office complex. Each office or floor can be configured as an autonomous private unit.
• Residential development. The homes share gardens, internal pathways, and common facilities.
• Collective garage. Parking spaces are registered individually to facilitate their sale or rental.

Applying these examples in real life is straightforward, as it only requires following the process guidelines. Among these cases, residential buildings are the most common due to their independent systems.
