Subtitle: Proposed amendments to the Criminal Procedure Act aim to establish secure, multi-signature protocols and fix major vulnerabilities in holding privately managed digital assets.
South Korean law enforcement and tax authorities are pushing for a comprehensive overhaul of the country’s legal and procedural frameworks to tackle the unique challenges posed by self-custodied cryptocurrencies. Historically, investigative agencies have relied on freezing accounts at centralized domestic exchanges. However, as bad actors increasingly turn to off-exchange, non-custodial hardware and software wallets to hide illicit funds, traditional asset seizure protocols have proved increasingly inadequate.
To close these gaps, officials from the National Tax Service (NTS), alongside legal experts, have formally proposed updates to the Criminal Procedure Act. The primary objective is to create clear statutory authority and explicit operational standards for confiscating digital assets held in private wallets—where control over funds depends entirely on possessing private cryptographic keys or recovery seed phrases rather than issuing a court order to an intermediary.
The Operational Challenge of Self-Custody
Unlike fiat bank accounts or centralized exchange profiles, self-custody wallets are decentralized and irreversible by design. A government cannot simply serve an administrative freezing order to a third party to gain control of a self-custodied wallet. Law enforcement must physically locate, secure, and correctly process private keys or recovery phrases.
The critical need for strict, standardized handling protocols was made clear following a severe security lapse during a law enforcement operation. South Korean police accidentally published a hardware wallet’s 12-word seed phrase in a press release meant to announce a successful asset seizure. Before the mistake could be corrected, an alert online observer utilized the exposed phrase to drain approximately $4.8 million in seized digital tokens from the wallet. The incident exposed major flaws in how state authorities handled offline digital wealth, highlighting the lack of trained personnel and uniform administrative procedures.
Key Amendments to the Criminal Procedure Act
To eliminate these vulnerabilities, the NTS policy paper—authored by senior investigation leads—outlines strict requirements for future warrants and asset handling procedures involving non-custodial crypto:
- Granular Warrant Specifications: Confiscation warrants targeting self-custodied assets will no longer be allowed to use broad language. Warrants must explicitly state the exact asset type, precise amounts, verified source addresses, designated state-controlled destination addresses, and the exact transfer methodology.
- Mitigating Single-Point Failure: Acknowledging that transferring confiscated assets into a single wallet controlled by one agency or individual creates an internal theft risk, the NTS proposes mandatory multi-signature protocols. Seized crypto would be deposited into joint-custody addresses co-managed by both judicial courts and investigative agencies, requiring multiple authorized signers to execute any future transaction.
- Audit Trails and Verification: Agencies must maintain fully documented custody logs, recording transaction details, responsible personnel, and the underlying legal basis at every stage from acquisition to final liquidation.
Integrating Seized Crypto into the National Strategy
These procedural updates to criminal law align with broader efforts across the South Korean government to integrate digital assets into the national legal framework.
Concurrently, the Ministry of Economy and Finance is advancing the National Asset Basic Act. This legislation aims to replace the legacy State Property Act of 1950, updating it to officially classify virtual assets acquired through tax enforcement, criminal seizures, and judicial confiscations as formal state property. The bill sets out systematic accounting, valuation, and public auction standards, ensuring that seized tokens are safely held and transparently converted into cash for the state treasury.
South Korea’s dual-track focus on reforming criminal procedure while updating state property laws highlights its intention to lead in crypto regulation. By replacing ad-hoc enforcement with clear, multi-signature custodial requirements, the country aims to prevent costly operational errors while ensuring that self-custodied crypto remains within reach of the law.
