Certificate of non-ownership of properties (Catastro)

What you need to have to hand

1. Cl@ve PIN or Permanente, certificado digital or DNIe. Without identification there’s no titularity certificate.
2. DNI/NIE and your NIF. If you request it for someone else, their NIF and the representation.
3. Territorial scope: province and, if required, municipality. This is what trips people up; many calls require the scope exactly.
4. A quiet moment: Cl@ve PIN expires in minutes and if the sede crashes you’ll need to retry.

Documentation

• Electronic identification: Cl@ve PIN/Permanente, certificado digital or DNIe.
• DNI/NIE of the applicant.
• NIF/NIE of the titular if you act for a third party.
• Apoderamiento in https://apodera.redsara.es (if you act online for a third party) or signed authorisation + DNI (if you go in person or use registro).
• Written request if you process it via the Registro Electrónico Común to ask for national scope.

Step by step

1. Go to https://www.sedecatastro.gob.es. Menu Certificaciones > Titularidad catastral de bienes inmuebles de una persona o entidad.
2. Identify yourself with Cl@ve, certificado or DNIe. If you act for someone else, check the apoderamiento is active.
3. Choose type of titularidad certification and pick the scope (province and, if applicable, municipality). If the call asks for several provinces, repeat the process.
4. Check the titular’s details (if it’s for you it autofills; if for a third party enter their NIF) and confirm.
5. Download the PDF with Código Seguro de Verificación (CSV). That CSV validates the document; keep it intact.
6. Need national scope and the sede doesn’t offer it? File a request at https://rec.redsara.es addressed to the Gerencia/Subgerencia del Catastro: ask for “certificación negativa de titularidad catastral en todo el territorio nacional”, attach your DNI and, if acting for someone else, the representation.

Time-savers

• Read the call: if it says “ámbito estatal”, save time and either request national scope by registro or bundle several provincial certificates into one submission.
• Cl@ve Permanente is more stable than PIN if you’re tight on time. PIN can expire mid-process.
• Verify the CSV before sending to third parties. On the sede you can check the document is valid and readable.
• If you need certificates for several people (e.g. a family), prepare apoderamientos or have each person get theirs with Cl@ve. You’ll avoid data-protection rejections.

Common mistakes that will mess up the process

1. Trying to request without identifying: public searches don’t show ownership; without Cl@ve/certificado you won’t get the certificate.
2. Choosing the wrong scope: you submit the wrong province and it gets rejected. Double-check whether they want a specific municipality, province or national scope.
3. No representation: asking for your partner’s certificate without apoderamiento = rejection. Fix it first at apodera.redsara.es or go in person with an authorisation.
4. Tampered PDF: printing, scanning and losing the CSV. Send it digitally with the CSV intact or a clear faithful copy.
5. Confusing Catastro with Registro: if they ask for Registro de la Propiedad, this won’t do. They are different systems.
