Mandatory Georeferencing for Leasing Photovoltaic Land

Key data

Solar energy promoters who lease parts of rural properties face a specific registration obstacle: without georeferencing of the leased portion, the Property Registry will deny registration. The Resolution of December 26, 2025 from the General Directorate of Legal Security and Public Faith (DGSJFP), published in the BOE on April 27, 2026 with reference BOE-A-2026-9143, confirms that the Property Registry of Mula's denial was correct and establishes doctrine applicable to all similar cases.

The resolved case is straightforward: a promoter attempted to register a lease on a part of a property intended for the construction of a photovoltaic plant. The Mula registrar denied registration because the georeferenced graphic representation of that portion was not provided. The DGSJFP ruled in favor of the registrar.

What does this regulation establish?

The resolution clearly establishes a requirement that was already in the Mortgage Law but was not always applied uniformly: when a lease right concerns a fraction of a property (not the entirety), it is essential to provide the georeferenced graphic representation of that specific portion in order to register it in the Property Registry.

The reason is both technical and legal: the Registry needs to identify with precision the exact location and extent of the right created. If the lease affects only part of the property, without georeferencing it is impossible to know what surface is bound to the contract.

The resolution does not create a new requirement: it consolidates and extends as registration doctrine what the Mortgage Law already required. From now on, any registrar can rely on this resolution to deny similar registrations that do not meet the requirement.

Economic and operational impact

The impact is not a fine or a fee: it is an operational blockade. A lease not registered in the Property Registry is a right that exists contractually but has no registration protection. This has direct consequences for photovoltaic promoters:

• Financing at risk: Banks and funds that finance photovoltaic projects typically require that rights to the land be registered. Without registration, financing can be blocked or become more expensive.
• Project delays: Correcting the deed, obtaining the technical georeferencing and resubmitting to the Registry takes weeks or months of delay in the construction schedule.
• Additional costs: Hiring a technician to prepare the georeferenced graphic representation, notarial fees for deed modification and registration fees for a second submission.
• Legal uncertainty against third parties: An unregistered lease is not enforceable against third-party good faith acquirers, which exposes the promoter to losing the right to the land if the property changes ownership.

Who does it affect?

• Photovoltaic plant promoters who lease agricultural or rural land to install their solar projects, especially when the lease concerns part of the property, not its entirety.
• Owners of rural properties who cede part of their land through lease for renewable energy projects and want that contract to be protected by registration.
• Notaries who authorize lease deeds intended for photovoltaic use: they must verify that the georeferencing of the leased portion is incorporated before authorizing the deed.
• Property registrars who receive these deeds: the resolution gives them explicit support to deny registrations that do not meet the requirement.
• Legal advisors and law firms specialized in real estate law and renewable energies that manage this type of transaction for their clients.

Practical example

A solar energy promotion company signs a lease contract with a farmer in the Region of Murcia on 15 hectares of a rural property of 40 hectares to install a photovoltaic plant. The contract is well drafted, the rent is agreed and the term is 25 years.

The notary authorizes the deed without incorporating the georeferenced graphic representation of the 15 leased hectares, because the contract describes the surface textually and with cadastral reference to the entire property.

When presenting the deed to the Property Registry, the registrar denies registration: the lease concerns a fraction of the property, not the entirety, and without georeferencing of that specific portion it is not possible to register it. This is exactly the case resolved by the DGSJFP in its resolution of December 26, 2025.

The promoter must now hire a technician (surveyor or engineer) to prepare the georeferenced graphic representation of the 15 hectares, modify the deed before a notary and restart the registration process. The delay can compromise the grid connection schedule and, with it, the project financing deadlines.

What should companies do now?

1. Review all photovoltaic lease contracts in progress that affect parts of properties and are not yet registered in the Property Registry. Identify which ones lack georeferenced graphic representation.
2. Incorporate georeferencing from the start of the process, before executing the notarial deed. Hire a qualified technician (surveyor, agricultural engineer or civil engineer) to prepare the graphic representation of the leased portion in a format compatible with the Registry.
3. Coordinate with the notary so that the lease deed expressly includes the georeferenced graphic representation of the fraction of property affected, not just the cadastral reference of the entire property.
4. Verify with the competent Property Registry the specific technical requirements of the accepted georeferencing file (GML format or others) before commissioning the technical work.
5. Update deed templates and internal processes to make georeferencing a mandatory step in all photovoltaic lease operations affecting property fractions.
