Denied registration of property boundaries in Colunga: key points for owners with boundary disputes

Key data

If you are the owner of a property in a subdivision parceled before georeferencing became mandatory, registering today the graphic representation can become a long and costly process when neighbors oppose it. That is exactly what happened with property 39,946 in Colunga: the registrar of Villaviciosa denied the registration of the alternative graphic base upon receiving opposition from neighboring properties backed by a technical report alleging overlaps with adjacent parcels.

The resolution of the General Directorate of Legal Security and Public Faith (DGSJFP) of March 25, 2026, published in the BOE on July 9, 2026, dismisses the appeal of the property owners and confirms the negative qualification of the registry.

What does this resolution establish?

The proceeding is processed under Article 199 of the Mortgage Law, which regulates the procedure for registering the georeferenced graphic representation of a property when the owner provides an alternative graphic base to the cadastral one.

The process was blocked for the following reasons:

• The neighboring properties filed formal opposition accompanied by a technical report that certified overlaps and discrepancies with the physical reality of the adjacent parcels.
• The appellants countered with their own tachymetric survey that attributed the error to the cadastral mapping, not to their property.
• According to the property owners, a unilateral boundary demarcation executed by the neighbors deprived them of 48.3 m² of their parcel.
• The original urban subdivision dates from 2004 and was carried out without registered coordinates, which makes coordination with the current registry difficult.

The DGSJFP confirms that, given the existence of technically substantiated opposition from neighboring properties, the registrar acted correctly in denying registration. The conflict over the physical reality of the boundaries must be resolved through another means—judicial or agreement between parties—before the graphic base can be registered.

Economic and operational impact

This resolution has direct practical consequences for any property owner who wants to georeference their property:

• The Article 199 Mortgage Law procedure is not an automatic formality. If a neighboring property opposes with a technical report, the registrar can—and must—deny registration, regardless of whether the owner provides their own survey.
• Two contradictory technical reports are not resolved at the registry. The DGSJFP does not assess which of the two surveys is more accurate: it refers the conflict to the judicial route.
• Old subdivisions without registered coordinates are especially vulnerable. The absence of original georeferencing (as in the case of the 2004 subdivision) generates legal uncertainty that is transferred to the current property owner.
• The cost of the dispute multiplies: tachymetric survey, appeal to the DGSJFP, and presumably a judicial proceeding if you want to resolve the substance of the matter.

Who does it affect?

• Property owners in subdivisions parceled before 2015 that do not have coordinates registered in the registry.
• Property owners who are processing or will process a proceeding under Article 199 of the Mortgage Law to register the graphic representation of their property.
• Property owners who have boundary disputes with neighbors in areas where cadastral mapping does not match physical reality.
• Developers and land managers who work with properties from old subdivisions without georeferencing.
• Lawyers, notaries and real estate managers who advise on registry-cadastre coordination processes.

Practical example

The case resolved in this resolution perfectly illustrates the problem. The owners of property 39,946 in Colunga initiate the Article 199 Mortgage Law proceeding to register their alternative graphic representation. The neighboring properties oppose and present a technical report alleging overlaps.

The property owners respond with their own tachymetric survey that concludes that the error is not theirs, but cadastral, and that the boundary demarcation executed unilaterally by the neighbors has deprived them of 48.3 m² of their parcel.

Result: the registrar of Villaviciosa denies registration. The property owners appeal to the DGSJFP. The DGSJFP dismisses the appeal and confirms the denial. The conflict over the 48.3 m² remains unresolved at the registry level and must be settled, if the property owners wish, before the courts.

The practical lesson: before initiating an Article 199 Mortgage Law proceeding on a property with potential boundary disputes, it is advisable to explore a prior agreement with neighboring properties or, at least, anticipate that technical opposition from a neighbor can paralyze the process indefinitely.

What should property owners do now?

1. Check if your property has coordinates registered in the registry. If it comes from a subdivision prior to 2015, it probably does not. Check with the corresponding Property Registry before initiating any procedure.
2. Sound out neighboring properties before filing the Article 199 Mortgage Law proceeding. If there is any discrepancy about boundaries, technical opposition from a neighbor can block the process. A prior agreement—or at least the absence of conflict—is key to the success of the procedure.
3. Commission your own tachymetric survey before initiating the proceeding. Detecting possible overlaps in advance allows you to correct the graphic base or anticipate the procedural strategy.
4. If you already have a negative qualification, consider the judicial route. The DGSJFP does not resolve conflicts over the physical reality of boundaries: that competence is exclusively judicial. If the 48.3 m²—or any other area—are economically relevant, the judicial proceeding may be the only way out.
5. Consult with a lawyer specialized in registry and real estate law before appealing to the DGSJFP, since appeals with little chance of success only prolong the process and generate additional costs.
