Grant powers in Apodera so someone can represent you online

What you need to have to hand

1. Cl@ve Permanente or certificado digital FNMT/DNIe. Cl@ve PIN can sometimes fail when signing.
2. DNI/NIE (and the physical ID if you go to an office).
3. NIF/NIE of the apoderado (or NIF of the company if it's a gestoría).
4. Scope of the power: general for the AGE, by organismo or by specific procedimiento.
5. Validity: pick an end date (don't leave powers forever if not needed).
6. Email and mobile for alerts and receipts.

Documentation

• Electronic ID (Cl@ve Permanente or certificado FNMT/DNIe) of the grantor.
• DNI/NIE of the grantor and of the apoderado (if in person, bring the original and, if possible, a copy of the apoderado's ID).
• Details of the organismo or procedimiento if you want to limit the power.
• If you do it at the office: cita previa at an Oficina de Asistencia en Materia de Registro.

Step by step

1. Go to Apodera: https://apodera.redsara.es/apodera/ and identify yourself with Cl@ve or certificate.
2. Alta de apoderamiento: choose the type (general, by organismo or by procedimiento) and tick the faculties (trámites, consultas, notificaciones).
3. Enter the apoderado: NIF/NIE with the letter correctly (or company NIF). Set validity and check everything.
4. Sign the alta electronically. The registration is immediate.
5. Download the receipt PDF and send it to the apoderado. They can verify it in their area.
6. In person (if you can't do it online): book at https://administracion.gob.es/pag_Home/atencionCiudadana/Oficinas.html, go with your DNI and the apoderado's details and formalise the apoderamiento “apud acta”. They will give you a resguardo.
7. Revoke or modify: from “Mis apoderamientos”, you can revoke or add new powers whenever you want.

Time-saving tips

• Limit the scope: if you only need one trámite, create the power by procedimiento. Less risk.
• End date: set a short expiry and renew if needed. That avoids a hanging power.
• If Cl@ve PIN fails, use Cl@ve Permanente or a certificado. Avoid the signature error loop.
• For gestorías: grant powers to the company (NIF) and let them organise internally. You keep control over scope and dates.

Common mistakes that can mess up the process

• Mixing up the apoderado's NIF: you give powers to the wrong person. Check twice before signing.
• Assuming it works for everything: AEAT, Seguridad Social and DGT usually use their own registry. If the trámite is theirs, grant the power also on their sede.
• Not setting an end date: you'll regret it later. Better a short expiry and renew if needed.
• Trying to sign with basic Cl@ve PIN: it can break. Use Cl@ve Permanente or certificado FNMT/DNIe.
• Not saving the receipt: if there's a dispute, the PDF is your lifesaver.
