Surface Rights Without Prior Segregation: What Changes for Developers

Key data

Establishing a surface right over part of a plot without prior segregation now has express registral backing. The Resolution of the DGSJFP of 18 December 2025 upholds the appeal lodged against the refusal of the Land Registrar of Mula and sets out a clear doctrine: prior registral segregation is not an essential requirement for registering this type of real right.

The determining criterion is the sufficient identification and delimitation of the portion in the constitutive title itself. If that condition is met, the registrar must register the right. This resolution has a direct impact on real estate transactions that until now were blocked or made more expensive by the requirement to segregate before executing the deed.

What does this regulation establish?

The DGSJFP resolves a specific dispute: the Land Registrar of Mula refused to register the establishment of a surface right over a portion of a plot, implicitly citing the need for prior segregation. The Dirección General upholds the appeal and sets out the following criteria:

• Prior registral segregation is not required to register a surface right over part of a plot.
• The affected portion must be sufficiently identified and delimited in the constitutive title of the right.
• The resolution sets out practical criteria on how that portion must be described in order to pass the registral review without the need for a division procedure.
• A surface right over part of a plot is a valid formula for real estate collaboration or financing without transfer of full ownership.

This doctrine is not new in its legal basis, but its express establishment in an upholding resolution against a registral refusal gives it practical binding force for future transactions throughout the territory.

Economic and operational impact

The requirement for prior segregation has a real and measurable cost for any real estate transaction: additional notarial fees, registral fees for the segregation, possible municipal subdivision licences and, above all, time. In renewable energy or infrastructure projects on third-party land, this process can cause delays of several months and significantly increase the cost of the legal structure.

With this consolidated doctrine, transactions using surface rights over part of a plot can:

• Avoid the segregation procedure and its associated costs.
• Reduce the time required to formalise and register the real right.
• Simplify the legal structure of renewable energy projects (photovoltaic, wind) on third-party land.
• Facilitate the establishment of rights for parking facilities or buildings on third-party land without altering the ownership of the parent plot.
• Make the use of surface rights as an instrument of real estate financing more agile without transfer of ownership.

The impact is particularly significant in the renewable energy sector, where it is common to lease or grant the use of a portion of agricultural land to install solar panels or wind turbines. The registral registration of the surface right strengthens the legal certainty of the project against third parties and facilitates its bank financing.

Who is affected?

• Property developers who develop projects on third-party land through surface rights.
• Plot owners who wish to grant the use of part of their land without selling or subdividing it.
• Companies in the renewable energy sector that install infrastructure on portions of agricultural or rural plots.
• Financial institutions that finance projects with security over registered surface rights.
• Land registrars, who are bound by this DGSJFP doctrine when reviewing similar titles.
• Notaries and legal advisors who draft constitutive titles of surface rights over portions of plots.
• Developers of parking facilities or installations on third-party land without acquisition of ownership.

Practical example

A solar energy company wants to install photovoltaic panels on 2 hectares of a 15-hectare rural plot owned by a farmer. The farmer does not want to sell or subdivide the plot, but is willing to grant the use of that portion for 30 years through a surface right.

Before this consolidated doctrine, the registrar could require the prior registral segregation of the 2 hectares, which involved: a segregation deed, a municipal subdivision licence (where applicable), registration of the resulting plot and only then the establishment of the surface right. A process that could take between 3 and 6 months and generate additional costs of several thousand euros.

With the doctrine established by the Resolution DGSJFP BOE-A-2026-6846, it is sufficient for the constitutive title of the surface right to sufficiently identify and delimit the 2-hectare portion (by means of a plan, georeferenced coordinates or other appropriate technical means). The registrar must register the right without requiring prior segregation. The transaction is simplified, made less expensive and accelerated.

What should companies do now?

1. Review blocked or pending transactions in which the registrar has required prior segregation to register a surface right: this doctrine may unblock them.
2. Ensure that the constitutive title sufficiently describes the affected portion: include a plan, exact surface area, boundaries or georeferenced coordinates to meet the identification and delimitation requirement.
3. Instruct notaries and legal advisors drafting surface right titles to incorporate the necessary technical description from the outset.
4. Evaluate renewable energy, parking or construction projects on third-party land that were discarded due to the complexity of segregation: they may now be viable with a simpler structure.
5. Consult with the competent registrar before signing if there are any doubts about the level of descriptive detail required in each specific case, in order to avoid negative qualifications.
