Access to Mi Carpeta Justicia with Cl@ve or certificate (no fuss)

What you need to have to hand

1. DNI/NIE and mobile linked to Cl@ve. Without the mobile the PIN won’t arrive.
2. Cl@ve PIN, Cl@ve Permanente or certificado FNMT/DNIe. PIN lets you consult; to sign, better Permanente/certificate.
3. Email that works for alerts and downloads.
4. AutoFirma installed if you’ll be signing something inside. Don’t leave this to the last minute.

Documentation

• DNI/NIE and mobile registered in Cl@ve.
• Certificado FNMT or DNIe with PIN (optional, alternative to Cl@ve PIN).
• Código de activación de Cl@ve if you registered by letter and haven’t activated it yet.
• Poder Apud Acta if you’ll consult/submit for someone else.

Step by step

1. Check your Cl@ve registration: at https://clave.gob.es/clave_Home/registro/Como-puedo-registrarme.html you can see how to register. If you’re already registered, confirm the mobile number is correct.
2. Register if you don’t have it: online with a certificate/DNIe or request a carta de invitación (takes 5–10 days). If you go to an office, book at a oficina de registro Cl@ve: https://clave.gob.es/clave_Home/registro/Oficinas-Registro.html
3. Install Cl@ve PIN and link your mobile. If you prefer, activate Cl@ve Permanente from your Cl@ve area.
4. Enter the sede of the Ministerio: https://sede.mjusticia.gob.es → Mi Carpeta Justicia. Identify with Cl@ve or certificate.
5. Accept terms and check data. Activate email/SMS alerts if the option appears.
6. Check your sections: “Mis expedientes” (nationality, Registro Civil Central, legal aid…), “Mis certificados y justificantes”, “Mis comunicaciones”. Download PDFs you need.
7. Does it ask you to sign? Install AutoFirma (https://firmaelectronica.gob.es/Home/Autofirma.html) and use Chrome/Edge or Firefox. Sign and save the receipt.

Time-saving tricks

• Cl@ve level: if something won’t open, switch from Cl@ve PIN to Permanente or use a certificate. Many errors are level-related.
• Browser: Chrome/Edge and Firefox usually work better. Safari causes issues with AutoFirma. Close previous Cl@ve sessions before logging in again.
• Keep DEHú handy: if you expect a notification, check https://dehu.redsara.es as well as the carpeta. Deadlines run even if no email arrives.
• Cl@ve appointments: AEAT offices work by appointment and Mondays fill up fast. Check early morning or late in the day.

Typical mistakes that will mess your process

1. Old mobile in Cl@ve: you request a PIN and it doesn’t arrive. Update the number in Cl@ve before you log in.
2. Basic registration: you can view but not sign. Fix: upgrade to advanced registration (office or with certificate/DNIe).
3. Out-of-date AutoFirma: signing fails and the browser hangs. Install the latest version first.
4. Expecting all judicial files: not all regional courts push data. If it doesn’t show, it doesn’t mean it doesn’t exist; check your other channels if it’s tied to a comunidad.
5. Logging in to act by representation without a poder: you’ll see nothing and get frustrated. Process the Apud Acta first if you’re acting for someone else.
