MitID, Digital Post, and e-Boks After a Death in Denmark
MitID, Digital Post, and e-Boks After a Death in Denmark
Denmark runs one of the most digitised public administrations in the world. Government agencies, banks, landlords, and utility companies communicate almost exclusively through Digital Post — a secure electronic mailbox tied to every resident's CPR number. When someone dies, this entire digital infrastructure shuts down instantly, creating what expat families experience as a "digital blackout."
What Happens Immediately
The moment a physician registers a death in the Civil Registration System (CPR), an automated cascade hits:
- MitID is deactivated — the deceased's secure digital ID stops working
- Digital Post (mit.dk) is permanently blocked — no new messages can be received, and existing messages become inaccessible
- e-Boks is locked — any reading access previously granted to family members is revoked
- All active powers of attorney (fuldmagt) become void — including digital powers of attorney, general powers of attorney, and future powers of attorney
This happens within hours, often before the family even realises it. Any third party who previously had reading access to the deceased's Digital Post loses that access simultaneously.
Why This Matters
In Denmark, critical documents arrive exclusively through Digital Post:
- Tax assessments and refund notices from Skattestyrelsen
- Rental contract correspondence from landlords
- Insurance policy details
- Pension fund statements
- Municipality notifications
- Utility account information
When Digital Post locks, the estate loses visibility into the deceased's financial obligations, active contracts, and pending claims. You cannot see what bills are due, what subscriptions are active, or what government agencies are trying to communicate.
How to Regain Access
Access to the deceased's digital correspondence requires the Probate Court to issue a formal Probate Court Certificate (Skifteretsattest). With this certificate, the estate's legal representative can apply for access through the "Rettighedsportalen for Digital Post" to establish an estate reader account (bobestyrer-adgang).
This process typically takes 3-4 weeks from the death. There is no way to accelerate it.

The CPR Number After Death
The deceased's CPR number (personnummer) is not deleted — it remains in the system permanently, marked with the date of death. The number continues to be used as the reference for all estate proceedings, tax filings, and property registrations. You'll need it for virtually every interaction with Danish authorities during the estate settlement.
If the deceased was a tourist or temporary visitor without a CPR number, the death is registered in the CPR system under a temporary identifier issued by the parish.
The Power of Attorney Trap
Many expats in Denmark set up a power of attorney (fuldmagt) — either a general power of attorney or a future power of attorney (fremtidsfuldmagt) — so that a trusted person can manage their affairs. These documents are designed for incapacity, not death.
Under Danish law, all powers of attorney terminate automatically and permanently at the moment of death. The designated attorney loses all authority. The only legal authority that survives death is the Probate Court Certificate.
This means that even if a spouse held a comprehensive power of attorney over all of the deceased's accounts and legal affairs, that authority evaporates instantly. They must wait for the Probate Court to reauthorise them through a different legal instrument.
Practical Implications for Foreign Families
- Don't assume you can log into anything — even if you have the deceased's passwords, MitID requires physical hardware or app authentication that is now deactivated
- Document what you can see before the freeze — if you're aware of an impending death, note account numbers, insurance policy details, and landlord contact information while Digital Post is still accessible
- The banks already know — financial institutions receive the CPR death notification automatically. Contacting the bank to explain the death is unnecessary; contacting them to discuss estate access is essential once you have the Skifteretsattest
The Denmark Expat Death Guide explains the complete digital recovery process, including how to petition for estate reader access and navigate Danish systems without MitID.
