How to Obtain and Enforce Freezing Orders for Cryptoassets in the UK (2026): a Practical Guide for Claimants

Understanding how to freeze cryptoassets in the UK in 2026 is now essential for any claimant, insolvency practitioner or solicitor confronting digital-asset fraud or misappropriation. The convergence of the Cryptoasset Regulations 2026, strengthened FCA perimeter guidance under CP26/13, and a renewed willingness from the High Court and Commercial Court to grant interim relief over digital wallets means the legal toolkit available to victims has expanded significantly. This guide provides a single, court-facing playbook, covering evidence preparation, service on exchanges, Crypto Wallet Freezing Orders (CWFOs), and cross-border enforcement, so that claimants can act decisively within the critical first 24 to 72 hours after discovering a loss.

Immediate action checklist for claimants:

• Apply for ex parte freezing relief. Instruct specialist counsel and prepare an urgent without-notice application to the High Court.
• Gather exchange records and wallet data. Capture blockchain explorer screenshots, transaction IDs and any KYC correspondence before data is deleted or accounts are closed.
• Preserve private keys and access credentials. Secure any seed phrases, hardware wallets or platform login details under your control.
• Consider a Norwich Pharmacal application. Where the identity of the fraudster or the custodian holding funds is unknown, a disclosure order against the exchange may be required before, or alongside, a freezing injunction.

Regulatory and Judicial Context (2026): What Changed and Why It Matters for Crypto Freezing Orders in the UK

The regulatory landscape governing cryptoassets in the United Kingdom shifted materially during 2025 and early 2026. The Financial Services and Markets Act 2000 was amended to bring a broader range of cryptoasset activities within the FCA’s regulatory perimeter. A draft statutory instrument published by HM Treasury extends the scope of the Cryptoasset Regulations, creating new authorisation requirements for exchanges and custodians operating in or targeting UK consumers. Simultaneously, the FCA published consultation paper CP26/13, setting out detailed perimeter guidance and proposed authorisation windows for cryptoasset firms.

Key Regulatory Dates and Practical Effect

From a litigation perspective, the practical effect of these changes is significant. Exchanges that are authorised, or seeking authorisation, under the new regime face enhanced compliance obligations and reputational risk if they fail to honour court orders. Industry observers expect this regulatory pressure to make service and enforcement of a crypto freezing order in the UK materially easier than it was even 18 months ago.

When to Seek a Freezing Order: Case Selection and Timing

A freezing injunction over cryptoassets is an extraordinary remedy. The English courts will not grant one lightly, and claimants must satisfy well-established interlocutory tests before relief is ordered. As Pinsent Masons’ practice guide on freezing injunctions summarises, the applicant must demonstrate a good arguable case on the merits, a real risk of dissipation of assets, and that the balance of convenience favours granting the order.

Claimants vs Insolvency Practitioners

Individual claimants typically rely on evidence of fraud, breach of fiduciary duty or misappropriation of funds to establish their substantive cause of action. Insolvency practitioners, liquidators and receivers, may additionally invoke statutory powers and the court’s inherent jurisdiction to preserve assets for the benefit of creditors. In either case, the applicant must show that the respondent’s cryptoassets are genuinely at risk of being moved, mixed or converted into other tokens beyond the reach of the court.

Urgency and Ex Parte Thresholds

The speed at which cryptoassets can be transferred, often within seconds, means that most interim relief applications in crypto fraud cases are made without notice (ex parte). The applicant must demonstrate why giving the respondent notice would defeat the purpose of the order. In practice, evidence of active wallet movements, layering through decentralised exchanges, or the respondent’s prior conduct in dissipating assets will satisfy this threshold. Courts expect full and frank disclosure from the applicant at the ex parte stage; any failure to disclose material matters can result in the order being discharged.

Types of Freezing Relief and Immediate Alternatives: How to Freeze Cryptoassets in the UK

Claimants and their advisers must choose the right form of relief, or combination of relief, for the circumstances. The principal options available in 2026 are set out in the comparison table below.

In many crypto fraud claims, a Norwich Pharmacal order against an exchange is sought first to identify the account holder, followed immediately by a freezing injunction once the respondent or the relevant wallet addresses are known. Where law enforcement is already investigating, a CWFO under the Proceeds of Crime Act framework, a tool available to UK law enforcement since 2024, may operate in parallel with civil relief. Claimants should consider seeking both routes simultaneously where the facts justify it.

Evidence Pack and Drafting Practicalities: Building the Cryptoasset Freezing Order Bundle

The quality of the evidence bundle is often decisive. Judges considering ex parte applications for interim relief in crypto cases expect granular, verifiable data linking the respondent to the assets in question. A well-prepared exhibit bundle accelerates the hearing and reduces the risk of discharge at the return date. The following checklist sets out the core exhibits that practitioners should assemble.

Evidence Checklist for a Crypto Freezing Injunction

• Wallet addresses. All known wallet addresses associated with the respondent, together with blockchain explorer screenshots showing current balances and recent transaction history.
• Transaction IDs (TxIDs). The specific on-chain transaction identifiers for each allegedly fraudulent or misappropriated transfer, annotated to show the flow of funds.
• Exchange account records. KYC correspondence, account statements, deposit and withdrawal histories obtained from any centralised exchange where the respondent held or holds an account.
• Blockchain tracing report. A professional tracing report from a specialist firm (e.g., Chainalysis, Elliptic or equivalent) mapping the movement of funds from the claimant’s wallet through intermediary addresses to the respondent’s known wallets or exchange deposits. Crypto asset tracing in the UK has become an established forensic discipline, and courts expect this evidence in contested applications.
• Expert affidavit or report. A short expert report confirming the methodology used for on-chain analysis, the reliability of the attribution, and the current location and estimated value of the traced assets.
• Evidence of dissipation risk. Any material showing the respondent’s prior conduct, rapid withdrawals, conversion to privacy coins, use of mixing services, or attempts to close exchange accounts.
• Witness statement. A first witness statement from the claimant or instructing solicitor setting out the factual background, the basis of the claim, the tracing analysis, and the grounds for seeking relief without notice.

Sample Exhibit Index

• Exhibit A: Claimant’s witness statement and statement of truth
• Exhibit B: Blockchain explorer screenshots (wallet addresses, balances, timestamps)
• Exhibit C: Transaction ID schedule with annotated flow-of-funds diagram
• Exhibit D: Exchange KYC and account records (redacted as necessary)
• Exhibit E: Professional blockchain tracing report
• Exhibit F: Expert report on attribution methodology and current asset valuation
• Exhibit G: Evidence of dissipation risk (withdrawal logs, mixer activity, communications)
• Exhibit H: Draft order (in the form approved by the Commercial Court or Chancery Division)

Practitioners should note that courts are increasingly familiar with on-chain evidence and expect it to be presented in a clear, indexed format. Exhibits should be paginated, cross-referenced and supported by concise explanatory notes. Firms that regularly handle crypto exchange operations and custody frameworks will be familiar with the KYC data formats that exchanges produce, which can streamline the preparation process.

Serving Orders on Exchanges, Custodians and Persons Unknown

Obtaining a freezing injunction is only the first step. The order must be effectively served on every party capable of dealing with the frozen cryptoassets, including exchanges, custodians and, in many crypto fraud cases, “persons unknown.” This is where many claimants encounter practical difficulty, and where careful advance planning makes the difference between preserving assets and watching them disappear.

Identifying the Relevant Custodian

On-chain analytics will typically reveal the exchange or custodian to which stolen funds have been transferred. Professional tracing firms can attribute deposit addresses to specific platforms with a high degree of confidence. Where the funds have been sent to a jurisdiction with a developed crypto-regulatory framework, the exchange is more likely to have a registered agent for service and established procedures for responding to court orders.

Service Strategies: Centralised vs Decentralised Platforms

• Centralised exchanges (CEXs). Most major centralised exchanges maintain compliance or legal departments and accept service by email or through a designated legal-process portal. The order should be served on the exchange’s registered office (if it has a UK presence) or via its appointed agent for service. A covering letter should specify the wallet addresses and account identifiers to be frozen, attach a sealed copy of the order, and request written confirmation of compliance within a stated timeframe (typically 24–48 hours).
• Decentralised exchanges and DeFi protocols. Where assets sit in smart contracts or liquidity pools without a centralised operator, enforcement is significantly more challenging. The court may authorise service by alternative means, including service via the blockchain itself (by sending a small transaction with an embedded message to the respondent’s wallet) or by publication on specified websites. Claimants should address this difficulty head-on in their evidence and propose a practical service mechanism.
• Persons unknown. In cases where the fraudster’s identity is not yet established, the court can grant a freezing order against “persons unknown” described by reference to their conduct (e.g., “the person or persons who misappropriated [X] BTC from wallet address [Y] on [date]”). The order is then served on the exchange holding the funds and, where possible, by alternative means on the respondent.

Gag orders, directions prohibiting the exchange from notifying the account holder of the freezing order, are commonly sought alongside service to prevent the respondent from moving assets before the order takes effect. Courts will grant such directions where there is evidence that tipping off would defeat the purpose of the injunction.

Enforcing Freezing Orders Across Borders: Practical Tactics for International Crypto Claims

Cryptoassets are borderless by design, and enforcing freezing orders internationally remains one of the most complex aspects of crypto fraud litigation. A Norton Rose Fulbright analysis highlights the practical difficulty of compelling offshore exchanges to honour English court orders. However, several enforcement pathways are available, and a structured approach improves the prospects of asset preservation.

Top Jurisdictions and Practical Notes

• Common-law jurisdictions with reciprocal enforcement. Orders from the English High Court are recognised with relative ease in jurisdictions such as Singapore, Hong Kong, the Cayman Islands and the BVI, where many crypto exchanges or their holding companies are registered. Claimants should consider applying for recognition of the English order in parallel proceedings.
• EU Member States (post-Brexit). Without the benefit of the Brussels Regulation recast, enforcement in EU jurisdictions now depends on local law and bilateral treaties. In practice, claimants may need to obtain a fresh freezing order from the local court, supported by the English order and evidence bundle.
• Uncooperative or unregulated exchanges. Where an exchange is domiciled in a jurisdiction with limited regulatory oversight and no enforcement treaty, civil remedies may be impractical. In such cases, claimants should explore whether the exchange has assets or operations in a cooperative jurisdiction that can be targeted, or whether law enforcement channels (including mutual legal assistance treaties) offer a more effective route.
• Asset tracing networks. Membership of professional networks, such as the International Centre for Asset Recovery or INSOL International, can accelerate the identification of local counsel and facilitate coordinated multi-jurisdictional enforcement. The Legal 500 UK asset tracing guide provides a useful overview of the enforcement landscape and specialist practitioners.

Industry observers expect the regulatory changes of 2026 to improve cooperation from exchanges that are seeking or holding FCA authorisation, since non-compliance with English court orders could jeopardise their regulatory status. The likely practical effect will be a narrowing of the enforcement gap for UK-focused platforms, even where the exchange’s servers or legal entity are offshore.

Interplay with Criminal Processes, CWFOs and Insolvency

Civil freezing relief does not operate in a vacuum. Where law enforcement is investigating the same facts, CWFO crypto UK powers under the Proceeds of Crime Act 2002 (as amended) allow police and the National Crime Agency to apply to a magistrates’ court for orders freezing specific wallet addresses. As Corker Binning’s practice overview explains, CWFOs provide a rapid operational freeze but are controlled by the investigating authority rather than the victim.

When to Pause Civil Steps

• Coordinating with law enforcement. Claimants should engage with the police or NCA at an early stage and seek confirmation that civil proceedings will not prejudice the criminal investigation. In some cases, law enforcement will welcome a civil freezing order as a complementary protective measure.
• Insolvency overlay. Where the respondent enters insolvency (or where the claimant is an insolvency officeholder), the freezing order may need to be varied to accommodate the statutory moratorium and the rights of other creditors. Officeholders should apply to the court for directions before taking steps that might conflict with the terms of the injunction.
• Disclosure obligations. Material obtained through civil disclosure (including Norwich Pharmacal orders) should not be shared with law enforcement without the court’s permission, unless a specific carve-out has been included in the order. Similarly, information received from police or prosecutors is typically subject to restrictions on use in civil proceedings.

Practical Checklists, Court Tactics and Hearing Preparation

Effective preparation for the ex parte hearing, and for the return date that follows, is critical. The checklist below summarises the steps from initial instruction to post-order compliance.

Filing and Hearing Checklist

• Instruct specialist counsel and solicitors. Choose practitioners with direct experience of crypto freezing applications in the Commercial Court or Chancery Division.
• Prepare the evidence bundle. Assemble the exhibits listed above, ensuring every document is paginated, indexed and cross-referenced in the witness statement.
• Draft the order. Use the standard-form freezing injunction (adapted for cryptoassets) and ensure it identifies the specific wallet addresses, exchange accounts and asset classes to be frozen.
• Reserve a hearing slot. For urgent applications, contact the duty judge’s clerk or use the urgent applications procedure. Out-of-hours applications can be made to the duty judge by telephone.
• Full and frank disclosure. Prepare a section of the skeleton argument addressing all material facts that might weigh against the grant of relief. Failure to comply is the single most common reason for discharge.
• Cross-undertaking in damages. Be prepared to offer a meaningful undertaking. Where the claimant’s financial position is uncertain, the court may require security (a payment into court or a bank guarantee).
• Serve the order immediately. Once the order is sealed, serve it on the respondent (if notified), all identified exchanges and any other relevant custodians without delay. Confirm service in writing and diarise the return date.

Typical Directions and Timelines Following an Order

The court will normally fix a return date within 7 to 14 days of the ex parte order. At the return date, the respondent has the opportunity to challenge the order and the claimant must demonstrate that the conditions for relief remain satisfied. Between the ex parte hearing and the return date, the claimant should monitor the frozen wallets for any attempted transfers, seek compliance confirmations from exchanges, and prepare updated evidence addressing any changes in circumstance. Costs budgeting and security for costs should be addressed early, as the court may make adverse costs orders if the freezing order is subsequently discharged.

Conclusion: How to Freeze Cryptoassets in the UK in 2026, Next Steps

The English courts have established, and continue to develop, a robust framework for granting freezing relief over cryptoassets. The 2026 regulatory reforms, including the draft Cryptoasset Regulations and FCA CP26/13, strengthen the position of claimants by imposing compliance obligations on exchanges and custodians that make service and enforcement more practical. For claimants and practitioners, the priority is speed: preserving on-chain evidence, instructing specialist counsel, and applying for interim relief crypto 2026 within the first 24 to 72 hours. Delays allow assets to be layered, mixed or moved beyond the practical reach of the court. Those facing cryptoasset fraud or misappropriation should seek specialist legal advice immediately and can find a specialist lawyer through the Global Law Experts directory.
