Crypto freezing injunctions are court orders that prevent thieves from moving or dissipating stolen digital assets while legal proceedings unfold. Courts in the UK, US, and other jurisdictions now routinely grant these orders against cryptocurrency held on exchanges and in identified wallets. The UK’s Property (Digital Assets etc.) Act 2025 formally recognizes cryptocurrency as property under English law, strengthening victims’ ability to obtain freezing orders, disclosure orders, and proprietary injunctions over stolen Bitcoin, Ethereum, USDT, and other digital assets.

At Crypto Trace Labs, our team provides expert witness testimony and investigation support for cryptocurrency freezing injunction applications. Our founders held VP and Director positions at Blockchain.com, Kraken, and Coinbase, giving us the technical expertise courts require when evaluating blockchain evidence. This guide explains how freezing injunctions work and what victims need to obtain one.

What Is a Cryptocurrency Freezing Injunction?

A freezing injunction – historically called a Mareva injunction in the UK – is an emergency court order that restrains a party from disposing of or dealing with specified assets. When applied to cryptocurrency, the order prohibits transferring coins from identified wallet addresses, withdrawing funds from exchange accounts, or converting digital assets to fiat currency.

English courts pioneered cryptocurrency freezing orders in AA v Persons Unknown (2019), where the High Court confirmed that Bitcoin constitutes property capable of being subject to proprietary injunctions. The Vorotyntseva v Money-4 Ltd (2018) case established that freezing orders covering £1.5 million in Bitcoin and Ethereum could be granted against cryptocurrency trading companies. The Sachs v Snape & Ors (2025) decision extended freezing orders to cover crypto wallets held by persons unknown.

US courts apply similar principles through temporary restraining orders and preliminary injunctions. In June 2025, the US Attorney’s Office filed a civil forfeiture complaint involving over $225 million in cryptocurrency traced to an international fraud scheme – the largest crypto seizure tied to investment fraud in US history.

These orders work because they target the choke points in cryptocurrency movement. While blockchain transactions cannot be reversed, exchanges and stablecoin issuers can freeze accounts and prevent further transfers when served with valid court orders.

How Do Courts Grant Freezing Orders Over Crypto?

Obtaining a cryptocurrency freezing injunction requires meeting specific legal thresholds that courts apply rigorously. The application process typically moves quickly – often within days or even hours of discovering theft – because speed determines whether assets can be preserved.

Courts evaluate freezing injunction applications against these criteria:

• Good Arguable Case – The applicant must demonstrate a genuine legal claim against the defendant, showing that cryptocurrency was obtained through fraud, theft, breach of contract, or other wrongdoing
• Real Risk of Dissipation – Evidence must establish that without an injunction, the defendant will likely move, hide, or spend the assets before judgment can be enforced
• Just and Convenient – The court must be satisfied that granting the order serves the interests of justice, balancing the applicant’s need for protection against any hardship to the defendant
• Full and Frank Disclosure – Applicants must present all material facts to the court, including information that might weaken their case, or risk having the order discharged

Blockchain forensics evidence plays a critical role in these applications. Tracing analysis from tools like Chainalysis and Elliptic demonstrates the movement of funds from victim wallets to defendant-controlled addresses. This evidence establishes both the traceability of assets and the identity of wallets to be frozen.

Most cryptocurrency freezing applications proceed without notice to the defendant – called ex parte applications – because alerting wrongdoers would give them opportunity to move assets before the order takes effect. Courts require particularly strong evidence for without-notice applications and typically schedule return hearings within days where defendants can contest the order.

What Types of Court Orders Help Crypto Theft Victims?

Courts deploy several complementary orders to protect cryptocurrency theft victims. Understanding the differences helps victims and their legal teams select the most effective remedies.

• Freezing Injunctions – Prevent defendants from dealing with assets up to a specified value, whether held in cryptocurrency, bank accounts, or other forms
• Proprietary Injunctions – Assert that specific assets belong to the claimant rather than the defendant, providing stronger protection than standard freezing orders
• Worldwide Freezing Orders – Extend freezing restrictions to assets held anywhere globally
• Norwich Pharmacal Orders – Compel innocent third parties like exchanges to disclose information about account holders and transactions
• Bankers Trust Orders – Require financial institutions to provide documents about assets they hold

The Ion Science Ltd v Persons Unknown (2020) case demonstrated how these orders work together. The Commercial Court granted a proprietary injunction, worldwide freezing order, and disclosure orders after victims lost approximately £577,000 in an ICO fraud.

Disclosure orders prove particularly valuable because they unmask anonymous fraudsters. When exchanges receive valid Norwich Pharmacal orders, they must reveal KYC information identifying account holders, transforming blockchain addresses into real defendants.

What Role Do Exchanges Play in Freezing Orders?

Cryptocurrency exchanges serve as critical enforcement points for freezing injunctions because they control the interface between digital assets and traditional financial systems. When courts issue orders against exchange-held assets, compliance depends on the exchange’s jurisdiction, regulatory status, and willingness to cooperate.

Major regulated exchanges including Coinbase, Kraken, and Binance maintain legal departments that process court orders from recognized jurisdictions. These platforms can freeze user accounts, prevent withdrawals, and provide disclosure information when served with valid legal process.

The practical process follows this sequence:

1. Service of Order – Legal representatives serve the court order on the exchange’s legal department
2. Account Identification – The exchange locates accounts matching specified wallet addresses or user identities
3. Implementation of Freeze – Trading, withdrawals, and transfers from identified accounts are suspended
4. Confirmation to Court – The exchange confirms compliance and may provide affidavit evidence

Stablecoin issuers add another enforcement layer. Tether has frozen over $3.3 billion in USDT across more than 7,200 wallet addresses, coordinating directly with law enforcement. Unlike decentralized cryptocurrencies, centralized stablecoins include smart contract functions enabling address blacklisting at the protocol level.

Crypto Trace Labs maintains direct relationships with compliance teams at major exchanges through our founders’ executive roles at leading platforms. These industry connections facilitate faster response times when clients pursue freezing orders.

What Challenges Limit Freezing Order Effectiveness?

Despite significant legal developments, cryptocurrency freezing injunctions face practical limitations. Understanding these challenges helps victims set realistic expectations.

• Jurisdictional Boundaries – Court orders bind parties within the issuing jurisdiction but may not be recognized elsewhere without additional proceedings
• Speed of Asset Movement – Sophisticated thieves can split and transfer funds across dozens of wallets within hours, outpacing legal processes
• Decentralized Protocols – Assets in DeFi protocols or self-custodied wallets may be beyond practical reach of court orders
• Mixed Funds – When stolen assets combine with legitimate funds on exchanges, tracing becomes technically complex
• Unknown Defendants – While courts can issue orders against persons unknown, enforcing judgments against unidentified parties presents difficulties

The Piroozzadeh v Persons Unknown (2023) case illustrated these limitations. The High Court discharged a freezing injunction against Binance after finding that stolen USDT had been swept into pooled addresses where tracing became impractical. Courts emphasize that freezing orders must serve a useful purpose.

Cross-border enforcement requires careful jurisdictional analysis. The D’Aloia v Persons Unknown (2024) decision confirmed that exchanges can defend claims using bona fide purchaser defenses if they acted in good faith.

How Does UK Law Now Protect Crypto Theft Victims?

The UK has established itself as a leading jurisdiction for cryptocurrency fraud litigation through progressive case law and recent legislation. The Property (Digital Assets etc) Act 2025 represents a watershed moment, formally codifying what courts had already recognized through common law.

Key legal developments include:

• Property Recognition – The Act confirms that digital assets constitute a third category of personal property
• Proprietary Remedies – Owners can pursue property-based claims including conversion, unjust enrichment, and constructive trust
• Freezing Relief – Courts apply traditional injunctive remedies to cryptocurrency without debating property status
• Proceeds of Crime Act Powers – The Economic Crime and Corporate Transparency Act 2023 amended POCA to allow seizure and civil recovery of crypto assets

The November 2025 O’Connor case demonstrated these powers in action. The High Court made a civil recovery order under POCA section 266, vesting over £4 million in cryptocurrency in a trustee for liquidation.

English courts have also developed innovative procedural approaches. In cases involving unknown defendants, courts permit service via NFT – sending notice of legal proceedings to blockchain addresses through non-fungible tokens.

What Evidence Do Courts Require for Freezing Orders?

Successful freezing injunction applications depend on presenting compelling evidence that meets judicial standards. Courts scrutinize blockchain evidence carefully, often requiring expert analysis.

Essential evidence includes:

• Ownership Proof – Documentation establishing the applicant owned the stolen assets
• Theft Evidence – Records showing how assets were misappropriated through hacking, fraud, or unauthorized access
• Tracing Analysis – Professional blockchain forensics demonstrating fund movement from victim wallets to defendant addresses
• Wallet Identification – Evidence linking specific addresses to the defendant through exchange KYC data or on-chain analysis
• Dissipation Risk – Facts supporting the conclusion that assets will be moved without court intervention

Expert witness testimony significantly strengthens applications. Courts increasingly expect blockchain forensics evidence from qualified professionals using tools from Chainalysis and Elliptic who can explain tracing methodologies and assist judges in understanding technical complexities.

Frequently Asked Questions

Can courts freeze Bitcoin held in private wallets?

Courts can issue orders prohibiting defendants from dealing with Bitcoin in private wallets, but enforcement depends on defendant compliance or identification of exchange touchpoints. If stolen Bitcoin moves to an exchange where the defendant has an account, the exchange can freeze those funds. Courts cannot technically prevent transactions from self-custodied wallets – they can only hold defendants in contempt for violating orders.

How quickly can a freezing injunction be obtained?

Emergency freezing orders can be obtained within 24 to 48 hours when circumstances warrant urgent action. Courts accommodate urgent applications through duty judges and expedited procedures because cryptocurrency can move almost instantly. The critical factor is preparation – having blockchain evidence and legal arguments ready allows legal teams to move quickly when theft is discovered.

Do freezing orders work against overseas exchanges?

Freezing orders bind parties within the court’s jurisdiction and may be recognized by overseas courts through international legal cooperation frameworks. Major exchanges often comply with orders from recognized jurisdictions regardless of incorporation location. However, exchanges in uncooperative jurisdictions present challenges requiring additional legal proceedings.

What does a freezing injunction cost to obtain?

Legal costs for cryptocurrency freezing injunctions typically range from £15,000 to £50,000 for straightforward cases, with complex multi-jurisdictional matters potentially exceeding £100,000. Successful applicants can often recover costs from defendants when judgments are enforced.

Can Tether freeze my USDT without a court order?

Yes. Tether’s terms of service permit token freezes when required by law or at its discretion to protect users. Tether has frozen billions in USDT in coordination with law enforcement, and its smart contracts include administrative functions enabling address blacklisting. This centralized control distinguishes stablecoins from decentralized cryptocurrencies and makes them more susceptible to enforcement actions but also creates risks for legitimate holders caught in broad freezing actions.

What happens after a freezing order is granted?

The frozen assets remain in place while the underlying legal case proceeds through disclosure proceedings, substantive hearings, and ultimately judgment. If the applicant succeeds, they can enforce the judgment against frozen assets. Courts may order cryptocurrency converted to fiat currency and transferred to the claimant, or order direct transfer of specific digital assets.

Can I get a freezing order against someone I cannot identify?

Yes. English courts routinely issue freezing orders against persons unknown in cryptocurrency fraud cases. The key requirement is identifying the assets to be frozen – specific wallet addresses or exchange accounts – even if the person controlling them remains anonymous. Disclosure orders against exchanges then help identify unknown defendants through KYC records.

How long do cryptocurrency freezing orders last?

Freezing orders remain in force until the court discharges them, typically when the underlying case concludes. Initial without-notice orders usually have return dates within 7 to 14 days where the order can be contested. If continued, orders may last months or years depending on litigation timelines.

What if the exchange refuses to comply with a freezing order?

Exchanges refusing to comply face contempt of court proceedings, resulting in fines, asset seizures, or operating restrictions. Regulated exchanges rarely refuse because doing so jeopardizes licenses and banking relationships. If an exchange is in an uncooperative jurisdiction, applicants may need to seek orders in the exchange’s home country.

Do I need blockchain forensics evidence for a freezing order?

Professional blockchain analysis significantly strengthens freezing applications but may not be strictly required for simple cases where tracing is straightforward. Courts increasingly expect expert evidence in complex cases involving multiple transactions, mixing services, or cross-chain movements. The tracing report demonstrates that frozen assets are indeed the stolen funds and establishes the chain of custody courts require for proprietary claims.

What Should You Do Next?

Cryptocurrency theft requires immediate action to maximize recovery prospects. The faster legal proceedings begin, the more likely that assets can be frozen before sophisticated thieves move them beyond practical reach. Courts have demonstrated willingness to protect cryptocurrency theft victims, but victims must bring properly prepared applications supported by competent evidence.
