Aqueduct Easement: Property Registry Cannot Rectify Graphic Registration at Request of Adjacent Owner

Key data

If you own an adjacent property and believe there is an aqueduct easement that is not registered in the Registry, you cannot resolve it by requesting a rectification of the graphic representation. That avenue is closed. The Resolution of December 26, 2025 from the General Directorate of Legal Security and Public Faith, published in the BOE on May 16, 2026, makes this clear: the registry procedure has precise limits and cannot be used to constitute or accredit real rights such as easements.

This resolution responds to an appeal against the refusal of the property registrar of Rivas Vaciamadrid. The adjacent owner requested that the existence of an aqueduct easement that he considered omitted be recorded in the georeferenced graphic registration of a property. The registrar denied the rectification. The DGSJFP confirms that refusal and precisely delimits what can and cannot be done through the registry procedure.

What does this resolution establish?

The resolution establishes three key principles that directly affect any conflict over easements and registry boundaries:

• The registry procedure is not the channel for constituting easements. The rectification of the georeferenced graphic representation of a property has a specific purpose: to correct errors in cartographic delimitation. It cannot be used to impose or accredit real rights such as an aqueduct easement.
• Adjacent owners cannot force modifications of third-party graphic registrations. The request for rectification of the graphic representation of a property at the instance of an adjacent third party has clear limits. The Registry cannot alter the registration of a property to reflect rights that have not been constituted through the corresponding legal channels.
• Easements must be formally accredited and constituted. For an aqueduct easement to be registered in the Property Registry, there must be a valid title: public deed of constitution, final judicial resolution or agreement formalized between the parties before a notary.

The resolution thus reinforces the principle of registry legal security: what accesses the Registry must be properly accredited, and the graphic rectification procedure cannot become an alternative avenue to create or modify real rights.

Economic and operational impact

The practical consequences of this resolution are direct for any owner or adjacent party involved in a conflict over easements or boundaries:

• Cost of judicial proceedings: With the registry avenue closed, the adjacent owner who wants to enforce an aqueduct easement must go to court, with the costs of legal representation, time and resources that this entails.
• Negotiation between parties: The most efficient alternative is to reach an agreement with the owner of the servient property and formalize it before a notary. This process has notarial and registry costs, but is significantly faster and more predictable than judicial proceedings.
• Risk for property owners: Property owners should know that an adjacent owner cannot alter their registry registration through this avenue. However, if there is a real unregistered easement, the conflict can lead to judicial proceedings that affect the availability and value of the property.
• Impact on real estate transactions: The existence of conflicts over unregistered easements can block or increase the cost of sales, mortgage financing or urban development operations of the affected properties.

Who does it affect?

• Property owners who have registered their georeferenced graphic representation and receive rectification requests from adjacent owners.
• Adjacent owners and holders of real rights who believe that an aqueduct easement or other real right is not correctly registered in the Registry.
• Real estate developers and promoters with properties in areas where there are historical water easements or aqueducts not formalized.
• Legal advisors and notaries who manage conflicts over boundaries, easements or registry graphic representations.
• Financial entities that finance operations on properties with possible unregistered charges or easements.
• Communities of owners and individuals in rural or peri-urban areas where water use and aqueducts generate frequent conflicts.

Practical example

A property owner in Rivas Vaciamadrid registers the georeferenced graphic representation of their land. Their adjacent neighbor believes that an aqueduct runs through that property that gives him the right to a water passage easement, but that easement was never formalized or registered in the Registry.

The adjacent owner requests the registrar to rectify the graphic registration to record the easement. The registrar denies the request. The adjacent owner appeals to the General Directorate of Legal Security and Public Faith. The DGSJFP confirms the refusal: the rectification of the graphic representation is not the mechanism to register an aqueduct easement.

The adjacent owner now has two real options: negotiate with the property owner the formal constitution of the easement through a public deed before a notary, or resort to judicial proceedings for a court to declare the existence of the easement and order its registration. Both avenues have very different costs and timelines, but they are the only valid ones after the closure of the registry avenue.

What should affected parties do now?

1. If you are an adjacent owner and believe there is an unregistered easement: Do not initiate a registry rectification procedure. That avenue is closed according to this resolution. Consult with a lawyer specializing in real estate law to assess whether judicial proceedings or direct negotiation is appropriate.
2. If you are a property owner and have received a request to rectify your graphic registration: Know your rights. The Registry cannot alter your registration to include an easement that has not been formally constituted. Keep all registry documentation of your property.
3. If there is a real easement that you want to formalize: Agree with the owner of the servient property on the constitution of the easement through a public deed before a notary and proceed with its registry registration. It is the only safe and effective path.
4. If you manage properties with possible unregistered historical easements: Conduct an audit of charges and real rights before any sales, mortgage or development operation. The existence of unregistered easements can generate significant legal and financial risks.
