Register on the municipal register (empadronamiento) at your Ayuntamiento

What to have ready

1. ID: DNI, NIE o pasaporte in date.
2. Proof of address: rental contract, escritura/nota simple or a recent utility bill.
3. Authorisation from the holder if you register at someone else’s home, with a copy of their DNI/NIE.
4. Hoja padronal from the Ayuntamiento, signed by all adults who are registering.
5. Minors: libro de familia or birth certificate and, if both parents aren’t registering, an authorisation from the absent parent or a judicial order (sentencia).

Documentation

• DNI/NIE/pasaporte (original and copy).
• Rental contract, escritura or nota simple; if it’s not in your name, add the authorisation from the holder.
• Recent utility bill (electric/water/gas) for the address (many Ayuntamientos ask for this when the contract is old or unclear).
• Hoja padronal (each Ayuntamiento has its own form).
• Authorisation from the absent parent or court ruling to register minors when required.

Step by step

1. Find the trámite on your Ayuntamiento’s web (e.g. sede.madrid.es, ajuntament.barcelona.cat, sede.valencia.es) and check if there’s an online option with Cl@ve or certificado.
2. Fill in the hoja padronal and collect the required signatures (property holder and the adults registering).
3. If online: upload sharp PDFs/scans and sign with Cl@ve Firma or your certificado. Save the receipt and monitor notifications.
4. If in person: book a cita previa for Padrón/Habitantes and go with originals and copies. They usually give the alta on the spot.
5. Request/download the volante or certificado de empadronamiento. They give it immediately or make it available in your municipal folder.
6. Forget about the old baja: the new Ayuntamiento handles it automatically.

Time-saving tips

• Book first thing: slots appear early and go fast, especially on Mondays.
• Bring copies of everything so you don’t need the office photocopier.
• If you’re not the contract holder, bring authorisation + holder’s DNI/NIE + a bill: without those they often turn you away.
• If the contract is very new, add deposit/IBI/utility activation documents to avoid hassle.
• Ask for a multiple-copy volante if you need several originals for other procedures.

Common mistakes that will stall you

• Thinking you need the baja from the previous municipality: you don’t, it’s automatic.
• Not bringing an authorisation when registering at someone else’s address.
• Blurry photos or poorly scanned documents for online submissions: they pause the trámite.
• Turning up without a cita in big cities: many offices won’t attend you.
• Believing NIE is mandatory: passport + proof of address is enough.
• Paying non-official sites: empadronamiento is free.
