Plot Encroachment in Registry-Cadastre Proceedings: 46 m² That Can Block Your Registration

Key data

If a neighbor is processing the coordination of their plot with the Cadastre and you believe they are taking part of your land, this resolution from the General Directorate of Legal Security and Public Faith (DGSJ) is directly relevant to you. The resolution of April 29, 2026, published in the BOE on August 8, 2026, clearly establishes that the opposition of an adjacent owner backed by qualified technical evidence must prevent the property registration of the georeferenced graphic representation.

The specific case affects registered plot 48,155 of the Property Registry of Lugo no. 1, processed through the proceeding of article 199.1 of the Mortgage Law. An adjacent property owner submitted a technical expert report demonstrating an error in the cadastral cartography equivalent to an encroachment of 46.58 m² of her property.

What does this resolution establish?

The proceeding under art. 199.1 of the Mortgage Law allows a property owner to register in the Registry the georeferenced graphic representation of their plot, coordinating it with the Cadastre. During processing, adjacent owners are notified and may object.

In this case, the adjacent owner objected by submitting a technical expert report certifying an error in the cadastral cartography: the proposed delimitation encroached 46.58 m² of her property. The registrar of the property of Lugo no. 1 dismissed the objections with two arguments:

• The error was of cadastral origin, not registral.
• The registration reduced the surface area of the plot (it did not increase it).

The DGSJ rejects this reasoning. According to the consolidated doctrine of the General Directorate, when an adjacent owner presents opposition properly justified with qualified technical evidence and there is genuine controversy over boundaries, the registrar must deny the registration of the graphic representation. The fact that the error is of cadastral origin or that the registered surface area is smaller does not neutralize the controversy over boundaries.

Economic and operational impact

This resolution has direct practical consequences in two opposite directions:

• For the property owner processing the proceeding: if an adjacent owner presents a solid expert report, the registration of the graphic representation is blocked. This paralyzes the Registry-Cadastre coordination and may affect sales operations, mortgages, or any legal act requiring registered georeferencing.
• For the affected adjacent owner: the resolution gives them an effective tool. It is not enough to object verbally: you must provide qualified technical evidence (expert report). If done correctly, the registration does not proceed.

The cost of a technical expert report to certify boundary encroachment typically ranges from several hundred to a few thousand euros depending on terrain complexity, but it can be the difference between losing or retaining square meters of property. The resolution does not set amounts or penalties: its value is procedural and preventive.

Who does it affect?

• Owners of plots adjacent to Registry-Cadastre coordination proceedings processed under art. 199.1 of the Mortgage Law.
• Real estate developers and construction companies processing plot regularizations with disputed boundaries.
• Lawyers and legal advisors managing objections to property registrations.
• Property registrars, who must apply DGSJ doctrine when evaluating objections from adjacent owners.
• Rural and urban property owners in areas with cadastral cartography with historical errors (frequent in Galicia and other communities with small-scale farming).

Practical example

Imagine your neighbor in Lugo initiates an art. 199.1 LH proceeding to register the graphic representation of their plot. The Registry notifies you as an adjacent owner. Reviewing the plans, you suspect that the proposed delimitation extends into your parcel.

Following the criteria of this resolution, the correct path is:

1. Commission a technical expert report from a surveyor or engineer certifying the cadastral error and quantifying the encroachment (in the resolved case: 46.58 m²).
2. Submit that report as formal opposition to the Property Registry within the proceeding deadline.
3. If the registrar dismisses your opposition arguing that the error is cadastral or that the registered surface area is smaller, you have grounds to file an appeal with the DGSJ, which—according to consolidated doctrine—must uphold your appeal and deny the registration.

This is exactly the path followed by the appellant in the case of plot 48,155 in Lugo, with a favorable outcome.

What should property owners do now?

1. Review if you have adjacent plots with art. 199.1 LH proceedings in progress. Check with your property registrar if there is any pending notification affecting you as an adjacent owner.
2. Do not object "without basis." An objection without technical evidence is not sufficient. The DGSJ requires qualified technical evidence: commission an expert report from a surveyor or competent technician before submitting objections.
3. Act within the proceeding deadline. The objection deadlines in the art. 199.1 LH proceeding are strict. Once the objection period closes, options are drastically reduced.
4. If the registrar dismisses your objection, appeal to the DGSJ. This resolution confirms that the doctrine of the organization protects the adjacent owner who provides technical evidence. The administrative appeal is the appropriate channel.
5. Seek advice from a lawyer specializing in property law and real estate before initiating or responding to any Registry-Cadastre coordination proceeding, especially in areas with unreliable historical cadastral cartography.
