If you act as a representative of a client before the Cadastre, or if you delegate to an advisor to manage procedures regarding your properties, the form you have been using until now is obsolete. The Resolution of October 5, 2026 from the General Directorate of the Cadastre approves a new standardized representation model with entry into force on October 10, 2026.
The change is not cosmetic: the new form substantially expands the catalog of procedures for which it is valid, unifies access to procedures both in electronic headquarters and in physical registries, and establishes clear rules on the scope of each representation granted.
What does this regulation establish?
The resolution approves a standardized document that replaces the representation model in force since 2020. The new form is valid for the following procedures before the General Directorate of the Cadastre:
| Covered procedure | Brief description |
|---|---|
| Declarations | Submission of cadastral declarations on behalf of the represented party |
| Requests | Formulation of requests before the Cadastre |
| Communications | Sending and receiving official communications |
| Cadastral inspection | Actions within the framework of inspection procedures |
| Cadastral regularization | Procedures for regularization of properties |
| Collective valuations | Participation in collective valuation procedures |
| Value reports | Actions related to the approval of value reports |
| Reposition appeals | Filing and follow-up of reposition appeals |
| Error correction | Requests for correction of errors in cadastral data |
Additionally, the form is also valid for accessing concluded files related to any of the above procedures.
Other key aspects of the new model:
- Dual submission channel: the document is accepted both in electronic headquarters and in physical registries.
- Representative's signature as guarantee: the representative guarantees with their signature the authenticity of the represented party's signature.
- Non-modifiable text: the form cannot be altered in any of its predefined fields, although representation can be proven by other legal means admitted.
- Scope limited by procedure: each document grants representation exclusively for the specific procedure in which it is presented, without effect on other procedures.
Economic and operational impact
This change does not generate additional direct costs for companies or individuals, but it does have an immediate operational impact for all law firms and management companies that handle cadastral matters on a regular basis.
The main operational effects are:
- Update of internal templates: any law firm that has saved representation models will need to replace them with the new official form from October 10, 2026.
- Review of powers in progress: representation documents signed under the 2020 model that have not yet been submitted may not be accepted after entry into force.
- Greater procedural coverage: the new model eliminates the need to manage specific authorizations for procedures that were not previously covered by the standard form, such as inspections, collective valuations or value reports.
- File management: since each form is only valid for a specific procedure, law firms with multiple open procedures for the same client will need to have a representation document for each one.
Who does it affect?
- Tax and fiscal advisors who handle declarations, appeals or requests before the Cadastre on behalf of their clients.
- Administrative management firms that manage regularizations, inspections or cadastral valuations.
- Property owners who delegate any procedure before the Cadastre to a third party.
- Companies with real estate assets whose tax or legal departments interact directly with the Cadastre.
- Developers and builders who participate in collective valuation procedures or value reports.
- Lawyers and solicitors who file reposition appeals or request correction of cadastral errors.
Practical example
A tax advisor manages three simultaneous procedures before the Cadastre for a company: a declaration of property alteration, a reposition appeal against a valuation, and a request for correction of an error in the cadastral reference.
With the previous 2020 model, there could have been ambiguity about whether a single representation document covered all these procedures. With the new model approved in 2026, the rule is clear: you need three different forms, one for each procedure, since each document only grants representation for the specific procedure in which it is presented.
Additionally, if the advisor needs to consult the already concluded files of those same procedures, the new form also expressly enables them to do so, something that the 2020 model did not contemplate in such a broad way.
What should companies do now?
- Download the new official form from the Cadastre's electronic headquarters or through the resolution published in the BOE and replace any previous version of the 2020 model.
- Review pending representation documents: if you have authorizations signed with the old model that you have not yet submitted, you will need to renew them with the new form to avoid rejection.
- Update the internal templates of the law firm or tax department so that all professionals exclusively use the new model from October 10, 2026.
- Plan one form per procedure: since each document only covers one specific procedure, make sure you have a specific authorization for each open procedure with the Cadastre (declaration, appeal, inspection, etc.).
- Remind clients that they must sign the new model if they have ongoing or planned procedures, since the representative guarantees with their signature the authenticity of the represented party's signature.
Frequently asked questions
Does the new 2026 Cadastre form completely replace the 2020 one?
Yes. The Resolution of October 5, 2026 approves a new standardized representation model that replaces the one in force since 2020. From October 10, 2026, the previous model should not be used for new submissions.
What Cadastre procedures is the new form valid for?
The new model covers 9 types of procedures: declarations, requests, communications, cadastral inspection, cadastral regularization, collective valuations, value reports, reposition appeals and error correction. It is also valid for accessing concluded files related to these procedures.
Does a single form work for multiple procedures of the same client?
No. Each representation document grants authorization exclusively for the specific procedure in which it is presented, without effect on other procedures. If you manage three different procedures for the same client, you need three independent forms.
Can the text of the new Cadastre representation form be modified?
No. The form text cannot be modified. However, the regulation allows representation to be proven by other legal means admitted if the standardized model is not used.
Is the new Cadastre form valid both in electronic headquarters and on paper?
Yes. The document is accepted both in electronic headquarters and in physical registries. In both cases, the representative guarantees with their signature the authenticity of the represented party's signature.
