What Liechtenstein's 2026 Arbitration Act Means for Banks and Financial Institutions, Interim Measures, Freezing Orders and Emergency Relief

The Liechtenstein Arbitration Act, which entered into force on 1 January 2026, fundamentally reshapes the way banks, custodians and financial institutions must respond to interim measures issued in connection with arbitration proceedings. For the first time, Liechtenstein’s statutory framework expressly codifies the power of courts to grant freezing orders and other conservatory relief even where the underlying dispute is subject to arbitration, and it introduces a formal recognition mechanism for measures granted by emergency arbitrators. If your institution is served with a freezing order tomorrow, the nine-step compliance playbook in this guide explains exactly what to do, and what happens if you do not.

Key Changes in the Liechtenstein Arbitration Act 2026, What Banks Must Know

Effective Date and Territorial Scope

The Arbitration Act 2026 took effect on 1 January 2026. It applies to all arbitration proceedings seated in Liechtenstein and, critically for banks, to any request for court-ordered interim measures directed at assets located within the principality, regardless of where the arbitration itself is seated. This territorial reach means that a bank holding assets on behalf of a foreign client can receive a binding court order under the new law even if the arbitral tribunal sits in London, Zurich or Singapore.

Statutory Highlights for Financial Institutions

The arbitration act 2026 introduces several provisions of direct concern to financial intermediaries. The most significant changes can be summarised as follows:

• Express court power to grant interim measures. The Act codifies the authority of Liechtenstein courts to issue conservatory injunctions, including freezing orders, asset preservation orders and orders for the provision of security, in support of pending or anticipated arbitration proceedings. This removes previous uncertainty about whether courts could intervene once a valid arbitration agreement existed.
• Emergency arbitrator recognition mechanism. For the first time, the Act creates a statutory pathway for the recognition and, where necessary, enforcement of measures ordered by an emergency arbitrator under institutional arbitration rules (such as those of the ICC, LCIA or the Liechtenstein Arbitration Association). Courts may convert an emergency arbitrator’s decision into a domestic enforcement title upon application.
• Concurrent jurisdiction preserved. The Act makes clear that the existence of an arbitration agreement does not bar a party from seeking interim relief from the courts. Both the arbitral tribunal and the court retain concurrent jurisdiction over interim measures in Liechtenstein, giving applicants flexibility and banks a wider range of potential orders to manage.
• Third-party service provisions. New procedural rules set out how interim orders must be served on third parties, principally banks, trust companies and custodians, and the timeframe within which those third parties must comply or seek to challenge the order.
• Strengthened enforcement sanctions. Non-compliance by a third party with a properly served court order now carries explicit statutory penalties, including coercive fines and, in certain circumstances, liability for losses caused by delay.

These changes align Liechtenstein more closely with the UNCITRAL Model Law framework and the arbitration regimes of neighbouring Switzerland and Austria, while retaining features specific to Liechtenstein’s role as a financial centre. The Liechtenstein Arbitration Association (LIS) has published updated guidance reflecting the new statutory landscape, and leading local practitioners have noted that the reforms significantly strengthen Liechtenstein’s attractiveness as both a seat of arbitration and a jurisdiction for effective asset preservation.

Types of Interim Relief Under the Liechtenstein Arbitration Act and Who Can Obtain Them

Understanding the different categories of arbitration interim relief available under the Act is essential for any bank compliance team, because the source and type of the measure determines whether it binds a third party directly. The Act contemplates three broad categories of interim measures in Liechtenstein:

Emergency Arbitrator vs Court Interim Measures, Which Binds a Third Party?

This distinction is the single most important operational point for banks. A court freezing order, once served in accordance with the Act’s procedural requirements, binds the bank immediately and independently. An order from an arbitral tribunal or emergency arbitrator does not, by itself, create an obligation on a third-party bank. The applicant must first obtain a court recognition or enforcement order. Industry observers expect that, in practice, well-advised applicants will often pursue both routes simultaneously, seeking an emergency arbitrator decision for speed and then applying for court recognition to bind third parties.

Banks should therefore scrutinise the origin of every measure they receive. If the order comes from a court, the bank must comply unless it obtains a stay. If it comes from a tribunal or emergency arbitrator, the bank should request evidence that a court recognition order has been granted before altering account operations.

Are Freezing Orders Enforceable Against Banks and Third Parties in Liechtenstein?

Yes, the Liechtenstein Arbitration Act expressly provides that court-issued freezing orders are enforceable against banks and other third parties when properly served. This is the direct answer to one of the most frequently asked questions since the Act came into force, and it represents a material change from the prior legal position where the scope of court intervention in arbitration-related matters was contested.

For a freezing order to be enforceable against a bank, the following conditions must generally be satisfied:

1. The order must have been issued by a court with jurisdiction under the Act, typically the Princely Court of Justice (Fürstliches Landgericht).
2. The order must identify, with reasonable specificity, the assets or accounts to be frozen and the parties concerned.
3. The order must be served on the bank through one of the methods prescribed by Liechtenstein procedural law, personal service, registered delivery, or service through the court registry.
4. The order must be accompanied by, or the bank must be able to obtain, a certified copy of the court’s decision and, if the order is in a foreign language, a certified German translation (or, in some cases, the bank may accept English if the order originates from an international tribunal process and the court has annexed the original).

Grounds for Enforcement or Refusal

The Act preserves the bank’s right to challenge an order on limited grounds. Recognised grounds for refusal or modification include defective service, lack of jurisdiction, manifest disproportionality, expiry of the order, or conflict with a binding order from another Liechtenstein court or authority (for example, a criminal-law asset seizure). The practical effect, however, is that banks carry the burden of challenging the order promptly; silence or inaction will be treated as compliance.

How to Verify Legitimacy and Scope

When served with a freezing order, a bank should immediately verify three things: (1) the order originates from the correct court and bears the court’s official seal or reference number; (2) the scope of the freeze is clear, does it cover all assets of a named account holder, or only a specified sum or identified account number?; and (3) the order has not expired or been superseded. Banks that act on forged or expired orders may face liability to the account holder, while banks that fail to act on valid orders face enforcement of freezing injunctions and statutory penalties.

Immediate Bank Response Checklist (Day 0–7), Operational Playbook for Banks Compliance With Freezing Orders

This section provides the core operational playbook for banks compliance freezing orders under the Liechtenstein Arbitration Act. Every bank, trust company and custodian operating in or holding assets connected to Liechtenstein should incorporate these steps into their internal compliance procedures.

1. Hour 0–2: Receipt, logging and legal hold. The moment a freezing order or interim measure is received, log it in the institution’s central legal-hold register. Assign a unique reference number. Immediately instruct all relevant departments, operations, payments, trade finance, wealth management, to suspend any outgoing transfers or instructions relating to the identified assets or accounts. Implement a system-level hold if the order references specific account numbers.
2. Hour 0–4: Notify internal legal and compliance. Escalate to the head of legal, the chief compliance officer and the bank’s designated AML/sanctions officer. If the institution has a board-level compliance committee, issue a preliminary notification. In Liechtenstein’s banking sector, many institutions operate with lean teams; early escalation prevents individual-officer risk.
3. Hour 0–6: Verify the order’s authenticity. Contact the issuing court’s registry to confirm the reference number, date and scope of the order. If the order was served by the applicant’s counsel rather than by the court directly, request a court-certified copy. Do not rely solely on uncertified documents delivered by email.
4. Day 1: Sanctions and AML screening. Run the account holder and all related parties through the institution’s sanctions and PEP screening tools. If the freezing order relates to assets that are also subject to international sanctions, dual-reporting obligations may apply (for example, to the Liechtenstein Financial Market Authority, FMA, or to the Financial Intelligence Unit).
5. Day 1–2: Request certified translation (if needed). If any part of the order is in a language other than German, request a certified German translation from the applicant’s counsel or the court registry. Banks are generally entitled to a German-language version before taking substantive compliance action, although they must still impose a precautionary hold immediately upon receipt of any plausibly authentic order.
6. Day 1–3: Assess scope and proportionality. Determine precisely which assets, accounts, safe-deposit boxes or sub-custodied instruments fall within the order’s scope. If the order is drafted broadly (for example, “all assets held for the benefit of X”), seek clarification from the court or the applicant’s counsel. Document your interpretation and the rationale in writing.
7. Day 2–5: Determine whether customer notification is permissible. Liechtenstein law does not impose a blanket prohibition on notifying account holders that a freezing order has been received, but some orders include an express confidentiality clause (Geheimhaltungsanordnung). If such a clause exists, the bank must not notify the customer. If no confidentiality clause is included, the bank may (and in many cases should, for duty-of-care reasons) notify the account holder within a reasonable period, giving the customer an opportunity to seek independent legal advice and, if appropriate, to apply to the court to vary or discharge the order.
8. Day 3–7: Appoint external counsel (if not already done). For complex or high-value freezing orders, or where the bank itself may need to challenge the order, instruct specialist external counsel in Liechtenstein with experience in international arbitration dispute resolution. Counsel should review the order, advise on the bank’s obligations and options, and, if necessary, prepare a challenge or application for modification.
9. Day 5–7: Preserve evidence and documentation. Place a legal hold on all internal communications, transaction records and correspondence related to the frozen account(s). Ensure that automated data-deletion schedules do not destroy relevant records. This evidence may be required if the bank is later called upon to provide disclosure to the court, or if a dispute arises about the timing and adequacy of the bank’s compliance.

Template: Bank Internal Escalation Notice

The following template can be adapted for use as an internal escalation memo upon receipt of a freezing order:

“To: Head of Legal / CCO / Board Compliance Committee
From: [Receiving Officer]
Date: [Date of receipt]
Re: Receipt of Court Freezing Order, Ref. [Court Reference Number]
We confirm receipt at [time] on [date] of a freezing order issued by [issuing court] in connection with arbitration proceedings between [Claimant] and [Respondent]. The order directs the bank to freeze [description of assets/accounts]. A precautionary hold has been applied. Authenticity verification with the court registry is in progress. Immediate actions under our Freezing Order Response Protocol have been initiated. External counsel appointment is recommended. Full details attached.”

Sample Checklist: Evidence and Preservation Actions

Evidence and Disclosure, What Courts Will Expect From Applicants Seeking Interim Measures in Liechtenstein

Banks receiving freezing orders are not passive bystanders. Understanding the evidentiary threshold that courts apply when granting interim measures helps compliance teams assess whether an order was properly obtained, and whether there may be grounds for challenge. Under the Liechtenstein Arbitration Act, courts will typically require an applicant to demonstrate the following before granting asset preservation measures in Liechtenstein:

• A prima facie valid claim. The applicant must show that an arguable claim exists, supported by a contract, arbitration clause, witness statements or documentary evidence.
• A real risk of dissipation. The applicant must demonstrate, with specific evidence, that the respondent is likely to move, conceal or dissipate the assets in question. General allegations of risk are insufficient; courts expect concrete indicators such as recent unusual transfers, corporate restructuring or statements of intent.
• Proportionality. The scope of the freezing order must be proportionate to the value of the underlying claim. Courts will not freeze assets worth significantly more than the disputed amount unless justified by specific circumstances.
• Urgency. The applicant must show that waiting for the arbitral tribunal to be constituted (or to act) would create an unacceptable risk of irreparable harm.
• Undertaking in damages. In most cases, the court will require the applicant to provide a cross-undertaking or security to compensate the respondent (and, potentially, affected third parties) if the freezing order is later found to have been unjustified.

Red Flags When Applicant Evidence Is Thin

Banks should be alert to situations where the applicant’s evidence appears deficient. If the order was granted ex parte (without notice to the respondent), if no cross-undertaking in damages was required, or if the description of assets is imprecise, these may be indicators that the order is vulnerable to challenge. A bank that identifies such red flags should immediately consult external counsel and consider whether to apply for the order’s discharge or modification, while maintaining its compliance hold in the interim.

Challenging Freezing Orders, When and How Banks Can Push Back

The Liechtenstein Arbitration Act preserves the right of affected third parties, including banks, to challenge a freezing order. This is not a theoretical right, it is a practical option that banks should actively evaluate in every case. Grounds on which a bank may challenge or seek to narrow a freezing order include:

• Lack of jurisdiction. The issuing court did not have territorial or subject-matter jurisdiction under the Act.
• Defective service. The order was not served in compliance with Liechtenstein procedural requirements.
• Disproportionality. The scope of the freeze exceeds what is necessary to protect the applicant’s claim.
• Competing proceedings. The same assets are subject to insolvency proceedings, criminal seizure orders, or enforcement actions in another jurisdiction, creating a conflict.
• Data protection and banking secrecy. The order, as drafted, would require the bank to disclose information in a manner that conflicts with Liechtenstein’s data protection or banking secrecy obligations. In practice, the court order generally overrides banking secrecy, but the bank may seek clarification on the scope of any disclosure requirement.
• Expiry or supersession. The order has lapsed, been varied or discharged by a subsequent court decision.

Quick Procedural Options for Banks

A bank wishing to challenge may file an application with the issuing court to vary, narrow or discharge the order. In urgent cases, the court may hear the application within days. Pending the outcome, the bank should maintain its compliance hold, failing to do so risks statutory penalties even if the challenge ultimately succeeds.

Interplay With AML and Sanctions Obligations

Compliance teams must recognise that a freezing order does not suspend the bank’s AML and sanctions obligations. If the frozen account triggers a suspicious-transaction report obligation, that report must still be filed. Equally, if the account holder or beneficial owner is subsequently designated under international sanctions, the bank’s obligations under the sanctions regime operate independently of, and in addition to, the court-ordered freeze. The Liechtenstein FMA has confirmed that institutions must maintain parallel compliance with both regimes.

Cross-Border Enforcement and Interaction With Other Jurisdictions

Liechtenstein’s position, situated between Switzerland and Austria, closely integrated with the EEA through its membership, and operating as a significant international financial centre, means that cross-border enforcement of freezing orders is a routine concern for banks. The Liechtenstein Arbitration Act addresses this in several ways.

First, the Act’s recognition mechanism for emergency arbitrator recognition decisions is designed to interoperate with the institutional rules of major arbitral bodies (ICC, LCIA, LIS, SCC). An emergency arbitrator decision obtained in another jurisdiction can be presented to a Liechtenstein court for recognition, converting it into a locally enforceable order. Conversely, a Liechtenstein court order can be presented for recognition in Switzerland under the bilateral enforcement treaties, or in EEA states under applicable instruments.

Second, banks operating across borders should be aware that a freezing order issued in Liechtenstein does not, by itself, bind the same bank’s branches or affiliates in Switzerland, the UK or other jurisdictions. Applicants seeking a worldwide freeze will typically need to obtain parallel orders in each relevant jurisdiction. However, Liechtenstein courts may order the respondent (as opposed to the bank) not to deal with assets worldwide, and breach of such an order may have consequences for the respondent in subsequent enforcement proceedings. As the comparative experience from other arbitration-friendly jurisdictions demonstrates, coordinated multi-jurisdictional freezing strategies are increasingly common in high-value disputes.

Emergency Arbitrator Awards, Recognition Abroad

The enforceability of emergency arbitrator decisions outside Liechtenstein remains uneven globally. While the Liechtenstein Arbitration Act provides a domestic recognition pathway, not all foreign jurisdictions treat emergency arbitrator awards as “awards” within the meaning of the New York Convention. Early indications suggest that the most reliable enforcement route continues to be a court order obtained in the jurisdiction where the assets are located, supported by the emergency arbitrator’s decision as persuasive evidence of urgency and merit.

Practical Templates and Timelines

The following timeline summarises the key milestones from receipt of a freezing order through to stabilised compliance and potential challenge. Banks should adapt this to their own internal governance requirements.

Sample request to applicant’s counsel for further documentation:

“Dear [Counsel],
We acknowledge receipt of the order of [Court] dated [date], reference [number]. In order to comply fully with the order and our regulatory obligations, we request the following within [5] business days: (1) a court-certified copy of the order bearing the court seal; (2) a certified German translation of all non-German-language portions; (3) confirmation of whether the order includes a confidentiality clause; (4) details of any cross-undertaking in damages provided by the applicant. Pending receipt of these documents, a precautionary hold has been applied to the assets identified in the order.”

Conclusion and Recommended Next Steps Under the Liechtenstein Arbitration Act

The Liechtenstein Arbitration Act has materially expanded the toolkit available to parties seeking to preserve assets in connection with arbitration proceedings, and it has correspondingly increased the compliance burden on banks, trust companies and custodians operating in or through the principality. The express codification of court powers to grant freezing orders, the new emergency arbitrator recognition mechanism, and the strengthened enforcement sanctions together create an environment in which speed, accuracy and procedural discipline are essential.

Banks that have not yet updated their internal freezing-order response protocols should do so as a matter of urgency. The nine-step checklist set out in this guide provides a starting framework, but every institution’s circumstances are different. For tailored advice, bespoke templates and guidance on specific orders, institutions are encouraged to consult a specialist dispute resolution practitioner in Liechtenstein through the Global Law Experts lawyer directory.
