1. What “Seized Wallet Management” Means in Denmark

A “wallet” can refer to:

(A) Traditional financial wallets

• Bank accounts
• Cash holdings
• Physical assets (safe deposits)

(B) Digital wallets (in modern cases)

• Crypto wallets (Ledger, Trezor, cold wallets)
• Exchange accounts (Coinbase-type custody wallets)
• “Seed phrase” controlled wallets

When Danish police seize a wallet, they typically:

• Freeze access (bank/account seizure under Retsplejeloven §§ 801–806)
• Take physical custody (hardware wallet)
• Secure digital access credentials (keys, passwords, devices)

2. Legal Basis for Seizure in Denmark

Key statutory foundation

🔹 Retsplejeloven § 802

Allows seizure of items:

• That may serve as evidence
• Or may be subject to confiscation

🔹 Retsplejeloven § 806

Allows urgent seizure without prior court approval if delay would risk loss of evidence or assets.

🔹 Straffeloven § 75

Provides for confiscation of proceeds of crime

3. Core Legal Conflict Areas

Seized wallet disputes usually involve:

3.1 Ownership vs. Control Conflict

Even if assets are seized legally:

• The suspect may claim continued ownership
• The state only has temporary custody

Conflict:

Is seizure merely control, or a deprivation of property?

This becomes important under ECHR Protocol 1 Article 1.

3.2 Crypto Wallet Confiscation Problem

Crypto introduces a unique legal issue:

• Control depends on private keys
• Courts must determine whether:
  • The wallet itself is seized, OR
  • The underlying crypto assets are seized

Key Danish court issue (seen in practice):

Courts have questioned whether:

• seizure of a “cold wallet device + recovery phrase”
• automatically equals seizure of the crypto assets inside

4. Important Case Law (Denmark & Nordic Practice)

⚖️ Case 1: EncroChat Evidence & Seizure Legitimacy

Østre Landsret (Eastern High Court), 2022

EncroChat investigation cases

Holding:

• Mobile phones and encrypted communication devices were lawfully seized
• Evidence obtained via foreign cooperation (France → Denmark) was admissible

Legal significance:

• Reinforces that technical digital devices can be seized even if encrypted
• Courts focus on lawful procedure + necessity, not just accessibility

📌 Impact on wallet disputes:

• Even inaccessible crypto wallets can be seized if linked to crime

⚖️ Case 2: Højesteret on EncroChat Evidence (2023)

UfR 2023.1368 (EncroChat case)

Holding:

• EncroChat data obtained via international cooperation was admissible
• No violation of due process or proportionality principles

Key reasoning:

• Data was not collected by Danish authorities initially
• But lawful transfer via judicial request made it valid

📌 Legal principle:

Cross-border digital evidence remains usable if procedural safeguards exist

⚖️ Case 3: Seizure of Physical Assets (Analogy Case)

Højesteret 102/2021 (Vehicle seizure case)

Although about a car, the principles apply to wallets:

Holding:

• Seizure and eventual confiscation must be proportionate
• Property rights under EU Charter were considered

📌 Legal analogy:

• Crypto wallets are treated like “seizable assets”
• But proportionality review always applies

5. Major Legal Conflicts in Seized Wallet Management

5.1 “Device vs Asset” Confusion

Courts struggle with:

• Is a Ledger device the “asset”?
• Or is Bitcoin stored inside the actual asset?

👉 Legal trend:
Denmark increasingly treats:

• Device = container
• Crypto = separate confiscatable property

5.2 Recovery Key Disputes

If authorities obtain:

• seed phrase
• private key
• password

Then:

• seizure becomes functional control, not just physical custody

But courts must still decide:

• Whether transfer to state wallet = new seizure or continuation

5.3 Procedural Fairness Issues

Common defense arguments:

• unlawful search of digital devices
• lack of notification rights (Retsplejeloven procedural rights)
• proportionality violation under ECHR

5.4 Cross-Border Evidence Conflicts

Many crypto cases involve:

• EUROPOL / foreign agencies
• offshore servers
• international warrant systems

Issue:

• Denmark must ensure foreign-gathered evidence meets domestic standards

6. Current Legal Position in Denmark (Practical Rule)

From case law trends:

Courts generally uphold seizure if:

• There is strong suspicion of crime
• Procedure follows Retsplejeloven §§ 801–806
• Evidence is relevant and proportionate

Courts may strike down or limit seizure if:

• procedure was materially defective
• proportionality is violated
• ownership ambiguity cannot be resolved

7. Summary (Key Legal Doctrine)

In Denmark, seized wallet management conflicts revolve around three principles:

1. Control vs Ownership

Seizure does not equal permanent deprivation.

2. Digital equivalence doctrine

Crypto wallets are treated like physical assets, but courts scrutinize:

• keys
• access
• control structure

3. Proportionality principle

Even lawful seizure must be necessary and proportionate under:

• Danish constitutional principles
• ECHR property protections
