"I never receive any correspondence until I get an embargo or a fine."

That was a subscriber, two months ago. She had a gestor. She filed everything on time. She just didn't know about the second inbox.

Spain stopped sending official government mail to your door around 2010. It built a new system instead: DEHú (Dirección Electrónica Habilitada Única) — Spain's unified government inbox — at dehu.redsara.es. The Agencia Tributaria sends requerimientos — formal information requests — there. The DGT sends fines. Seguridad Social sends contribution demands. Your ayuntamiento can send property tax notices.

All are legally binding. All considered delivered ten days after posting, whether you've opened them or not.

The Agencia Tributaria's requerimiento — formal request for information or documentation — gives you ten days to respond. Miss it, and the penalty starts at €150. If the underlying query concerns a tax discrepancy, a propuesta de liquidación — proposed tax settlement — follows. Miss that, and it becomes final: the full amount, plus surcharges up to 20%, plus late payment interest.

Traffic fines from the DGT go here. If you registered as a Spanish resident, you are likely already in the system as a mandatory recipient.

Court proceedings are handled through a separate platform called LexNET, used by all of Spain's civil, criminal, employment, and administrative courts. A property dispute with a builder, an inheritance claim, a contractor who decided to pursue unpaid fees: the summons, the judgment, the appeal deadline — all sent electronically. If you don't access the notification within 3 days, it will be published on the TEJU (Tablón Edictal Judicial Único) — Spain's judicial bulletin board. After that, it escalates to the BOE — Boletín Oficial del Estado — Spain's official state gazette. Once published in the BOE, you are legally notified. Full stop. Your window to respond starts ticking, whether you have ever seen the original.

This is the blind spot.

Your gestor covers what you hired them for: filing your quarterly modelos — tax returns, managing your TIE renewal, and dealing with Hacienda when you have explicitly delegated specific tasks.

DEHú notifications go to you. They are linked to your NIE, your individual certificado digital — digital identity certificate, or your Cl@ve — Spain's government digital ID system. These are personal credentials. Unless you have formally granted your gestor a digital apoderamiento — power of attorney over your government mailbox, they cannot see what is arriving.

Most people have not done this. Many gestores do not raise it proactively. It is a specific administrative step, not automatic.

The result: you can be fully compliant on every filing and still have a requerimiento sitting unread in DEHú, legally delivered, with the response window already closing. The Agencia Tributaria does not call first. It sends the notification and starts the clock.

Check dehu.redsara.es. Log in with your certificado digital or Cl@ve credentials. If you have never done this before, there may already be notifications waiting. The portal shows when each item was posted and the ten-day delivery date.

Ask your gestor a direct question: "Do you have access to my DEHú mailbox?" If they don't, ask what is required to grant them an apoderamiento through the Agencia Tributaria's sede electrónica — the official electronic government portal at sede.agenciatributaria.gob.es. The Agencia Tributaria Delegación de Málaga handles in-person apoderamiento requests; verify their current address at sede.agenciatributaria.gob.es before visiting (Confirmed March 2026).

Set up email alerts. Inside DEHú, you can configure email notifications for new items. It does not replace checking the portal, but it removes the excuse for not knowing something landed.

Giving your gestor an apoderamiento — the specific administrative step to route your notifications through a representative.

Missed a notification? What to do in the first 24 hours — if the clock is already running.

Two phrases worth having ready:

"¿Tienes acceso a mi DEHú?" — Do you have access to my government inbox? (for your gestor)

"Quiero concederte un apoderamiento electrónico." — I want to grant you a digital power of attorney.

Spain's notification system works exactly as designed. The notifications go out on time, the ten-day clock runs precisely, and the courts escalate methodically. Nothing fails on their side.

What fails is the assumption that someone is monitoring it for you. Check the portal. Ask the question. The €150 penalty is the inexpensive version of this problem.
