Cadastral conflict in Alcorcón: what happens when two properties claim the same plot

Key data

Two distinct registered properties cannot share the same cadastral plot: when that occurs, the Property Registry cannot register the graphic representation of either until a judge resolves who has the right. That is exactly what has happened in Alcorcón with registered property 3,653 and cadastral plot 199 of polygon 1, and the Resolution of April 15, 2026 from the DGSJFP confirms it.

The company Rehusa SA appealed the negative qualification from the Property Registrar of Alcorcón no. 1, which had suspended the registration of the georeferenced cadastral graphic representation of said property. The DGSJFP dismisses the appeal and ratifies the suspension.

What does this resolution establish?

The procedure for registering the graphic representation of a property is regulated in article 199.1 of the Mortgage Law. This article allows coordination between the Property Registry and the Cadastre, but requires that there are no well-founded doubts about the identity of the property.

In this case, the conflict arises because two distinct registered properties claim correspondence with the same cadastral plot (plot 199, polygon 1 of Alcorcón). Faced with this situation, the registrar considered that there were well-founded doubts of identity that prevented registration, relying on both article 199.1 ML and consolidated case law from the DGSJFP itself.

The elements that Rehusa SA provided to prove its right over the plot were the following:

• Decades of peaceful and uninterrupted possession of the plot
• Continuous payment of Property Tax (IBI)
• CAP (Common Agricultural Policy) declarations on the plot
• Lease contracts for the same

However, the DGSJFP concludes that, despite the strength of these possessory indicators, none of them is sufficient to resolve the ownership conflict in the registry proceedings. When two distinct registered holders claim the same cadastral plot, the procedure of article 199 ML is not the appropriate channel: the dispute must be resolved before the courts.

Economic and operational impact

This type of conflict has direct practical and economic consequences for affected owners:

• Blocking of registry registration: while the conflict is not resolved judicially, neither of the two properties can register its cadastral graphic representation, which prevents full Cadastre-Registry coordination.
• Limitations for transferring or encumbering the property: the lack of cadastral coordination can generate problems in sales, mortgages or any operation requiring precise property identification.
• Judicial costs: the only way to resolve the conflict is through ordinary judicial proceedings, with the costs of lawyer, court officer and litigation time that this entails.
• Risk for investments in the property: any improvement, investment or development on the plot remains in a situation of legal uncertainty until the litigation is resolved.

The resolution does not establish direct economic sanctions, but the indirect cost of not being able to register, sell or mortgage with full guarantees can be very high, especially in rural properties with active agricultural or rental activity as is the case with Rehusa SA.

Who does it affect?

• Owners of rural properties who have initiated or want to initiate the procedure of article 199 ML to coordinate their property with the Cadastre.
• Agricultural or rental companies that operate properties with possible cadastral overlaps with other registered properties.
• Buyers and real estate developers who acquire properties without previously verifying unique cadastral correspondence.
• Property registrars, who must apply this DGSJFP criterion when qualifying article 199 ML files with neighbors who prove contradictory rights.
• Legal advisors and notaries who process operations on properties with potential cadastral identity conflict.

Practical example

Rehusa SA has been operating plot 199 of polygon 1 of Alcorcón for decades: it pays IBI, has signed lease contracts and has submitted CAP declarations on it. When it tries to register the cadastral graphic representation of its registered property 3,653 through the procedure of article 199 ML, the registrar detects that another distinct registered property also claims correspondence with that same cadastral plot.

Despite all the documentation provided by Rehusa SA, the registrar suspends the registration due to well-founded doubts of identity. Rehusa SA appeals to the DGSJFP, which dismisses the appeal and confirms that the only way is to go to court so that a judge determines which of the two registered properties has the right to cadastral plot 199. Meanwhile, the registration remains suspended and Cadastre-Registry coordination is blocked.

This case illustrates that proven possession, tax payment and lease contracts are not sufficient in registry proceedings when there is a conflict of double registered ownership over the same cadastral plot.

What should property owners do now?

1. Verify the cadastral situation of your property before initiating any article 199 ML procedure: check on the Cadastre Electronic Office that there is no other registered property claiming the same cadastral plot.
2. Gather all available possessory documentation: IBI receipts, lease contracts, CAP declarations, deeds, historical aerial photographs. Although they do not resolve the registry conflict, they are fundamental evidence in the subsequent judicial proceeding.
3. Consult with a lawyer specializing in real estate and registry law before submitting the file, especially if there are signs of overlap with other neighboring properties.
4. If you already have the registration suspended, initiate ordinary judicial proceedings: according to the DGSJFP, it is the only valid channel to resolve the ownership conflict when two registered properties claim the same cadastral plot.
5. If you are a buyer or investor, request a simple note and cadastral certification before closing any operation on rural properties to detect possible identity conflicts that block future registration.
