How to Serve Legal Papers on Credit Suisse

Credit Suisse no longer exists as an independent institution. Credit Suisse Group AG was absorbed into UBS Group AG on June 12, 2023 under Swiss emergency merger law, and Credit Suisse AG itself ceased to exist as a separate legal entity on May 31, 2024 when it was fully merged into UBS AG. If your complaint or summons names “Credit Suisse” as a defendant, you face an immediate threshold problem: you may be naming an entity that cannot receive service because it no longer exists under any legal form. Serving a dissolved foreign corporation without understanding successor mechanics is not just procedurally defective — it can result in a default judgment that gets vacated years later when the defendant challenges service validity.

Three Credit Suisse entities incorporated in Delaware survive as wind-down shells: Credit Suisse Securities (USA) LLC, Credit Suisse (USA), Inc., and Credit Suisse Holdings (USA), Inc. These entities can still be served through their registered agent, Corporation Service Company, in Wilmington. For claims against Credit Suisse Group AG or Credit Suisse AG — the Swiss parent entities — service must go to their legal successors, UBS Group AG and UBS AG respectively, through the Hague Service Convention’s Article 5 Central Authority procedure. Switzerland formally objects to every alternative service method under the Convention, making the Central Authority route in Zurich the only lawfully recognized option.

Undisputed Legal has served process on dissolved multinational corporations and their successors across more than 120 countries. We understand when FRCP 25(c) substitution motions are required before service can be attempted, which Hague route Switzerland will accept, and how to generate GPS-verified records that survive successor-entity service challenges in federal and state court.

Why Serving Credit Suisse Is Harder Than Most Financial Defendants

A Two-Tier Extinction Timeline That Creates Defendant-Identification Traps

Credit Suisse’s collapse unfolded in two distinct legal events separated by nearly a year, not a single dissolution. On March 19, 2023, UBS Group AG agreed to acquire Credit Suisse Group AG under emergency Swiss federal intervention orchestrated by FINMA and the Swiss Federal Council to prevent a systemic banking collapse. The holding company merger closed on June 12, 2023 — that is the date Credit Suisse Group AG ceased to exist as a separate legal entity under Swiss law. Approximately eleven months later, on May 31, 2024, Credit Suisse AG itself was merged into UBS AG, completing the operational integration and eliminating the bank as a legal entity. These two dates are legally distinct: claims against the parent holding company and claims against the operating bank follow different successor chains.

Courts applying FRCP 25(c) look at whether the transfer of interest was voluntary, whether adequate notice was given, and whether service on the successor fairly reaches the party bound by the underlying obligation. Failing to research which dissolution date applies to which entity — and which successor inherits the specific liability being sued upon — is the most common procedural mistake in Credit Suisse litigation initiated after 2023. An attorney who files against “Credit Suisse AG” after May 31, 2024 without amending the complaint to name UBS AG as successor has not sued the correct defendant, and a process server who delivers documents to a Credit Suisse New York address after that date has not achieved valid service.

FRCP 25(c) Successor Substitution — Motion Practice May Be Required Before Service Is Possible

Federal Rule of Civil Procedure 25(c) provides that when an interest is transferred after an action is filed, the court may allow the action to continue against the original party or direct substitution of the transferee. For cases already pending when Credit Suisse dissolved, plaintiffs needed to file a substitution motion naming UBS Group AG or UBS AG before service on the successor becomes procedurally secure. For new actions filed after the extinction dates, the complaint itself should name UBS as the successor defendant from the outset, supported by a factual recitation of the merger history establishing why UBS inherited the specific obligation being sued upon.

Service on the wrong entity — attempting to serve Credit Suisse AG at a New York address after May 31, 2024 — creates a strong argument that no valid service was ever made. That argument does not disappear just because defense counsel later appears voluntarily; courts have independent discretion to find service defective and may require the plaintiff to re-serve at their own cost. The proper practice is to identify the correct successor defendant, obtain a reissued summons naming that party, and serve through the correct legal channel before limitations deadlines foreclose refiling.

Switzerland Blocks Every Hague Service Route Except Article 5 Central Authority

Switzerland is a Contracting State to the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters (15 U.S.T. 2396), but it has entered formal objections that eliminate nearly every alternative service method available under the treaty. Switzerland filed objections to Articles 8 and 10 of the Convention in their entirety. Article 8 permits service directly through diplomatic channels; Switzerland bars it. Article 10 permits service by postal channels, service through judicial officers of the state of destination, and service through persons competent under local law; Switzerland bars all of those sub-routes. That leaves Article 5 — service through the designated Central Authority in the canton of Zurich — as the exclusive lawful channel for formal service on UBS Group AG or UBS AG as Credit Suisse successors.

The designated Central Authority for the canton of Zurich is the Obergericht des Kantons Zürich, located at Hirschengraben 13/15, Postfach, 8021 Zürich, Switzerland. The Obergericht processes requests under Article 5 and will not accept a request that does not include a certified German translation of every document being served. Requests submitted solely in English are returned unexecuted. The Article 5 route typically requires four to twelve months depending on document volume and current Obergericht workload. Attempting to shortcut this timeline by serving a UBS registered agent in the United States as substitute service on the Swiss parent is not legally equivalent — courts in multiple circuits have held that service on a domestic subsidiary does not perfect service on a foreign parent unless an explicit agency relationship for service of process has been established and the defendant consents to that form of service.

Three Delaware Wind-Down Entities Remain Registerable — But Their Status Is Evolving

Credit Suisse Securities (USA) LLC (FINRA CRD No. 816), Credit Suisse (USA), Inc., and Credit Suisse Holdings (USA), Inc. remain registered in Delaware and maintain Corporation Service Company as their registered agent at 251 Little Falls Drive, Wilmington, DE 19808. However, wind-down status means their asset bases, personnel, and operational footprint are contracting steadily. As of July 1, 2025, vendor contracts previously held by Credit Suisse Securities (USA) LLC were migrated to UBS Securities LLC, reflecting the progressive integration of its business into the UBS platform. For money-judgment plaintiffs, this matters less immediately — a judgment against a surviving Delaware entity can still be enforced against remaining assets. But for plaintiffs seeking injunctive relief or attachment that depends on the defendant maintaining specific assets in a specific form, a wind-down shell may lack those assets even after service is validly perfected.

The critical discipline before serving any Delaware Credit Suisse entity is to verify current registration through the Delaware Division of Corporations. Wind-down entities can be dissolved or withdrawn from Delaware registration while their FINRA or SEC records remain visible. If the Delaware registration has lapsed, service on CSC at 251 Little Falls Drive will not create valid personal jurisdiction, regardless of whether FINRA shows the entity as active. Confirm the Delaware status before dispatching a process server.

Our Process for Serving Credit Suisse

1. Defendant identification audit. We review your summons and complaint to determine which Credit Suisse entity is named: a Swiss holding company (Group AG, Credit Suisse AG), a surviving Delaware wind-down entity, or a predecessor entity that ceased to exist before your claim was filed. We identify the correct current legal defendant and, if applicable, the FRCP 25(c) successor that should be named instead.
2. Successor substitution review. If your named defendant is Credit Suisse Group AG or Credit Suisse AG, we document the merger timeline — Group AG extinct June 12, 2023; Credit Suisse AG extinct May 31, 2024 — and the corresponding UBS successor entities so your counsel can file a substitution motion or amend the complaint before service is attempted on the wrong party.
3. Document preparation and routing decision. For Delaware wind-down entities, we prepare a standard process package for CSC delivery in Wilmington. For Swiss successors (UBS Group AG or UBS AG), we prepare a Hague Article 5 request on the USM-94 form and coordinate certified German translations of every document to be served through the Obergericht.
4. Registered agent service for Delaware entities. Our field agent serves Corporation Service Company at 251 Little Falls Drive, Wilmington, DE 19808 under Delaware’s process service rules. Every service attempt is GPS-verified with timestamped location data and a contemporaneous photo record establishing the date, time, and location of delivery.
5. Central Authority transmission for Swiss successor entities. We submit the complete Article 5 request package to the Obergericht des Kantons Zürich, including the translated documents, completed USM-94 form, and applicable Central Authority fee. We track the request through the Obergericht workflow and provide status updates at each documented processing milestone.
6. Affidavit of service preparation. Upon execution of domestic service, we prepare a notarized affidavit of service documenting the method, date, recipient, GPS-verified service location, and chain-of-custody record. For Swiss service, the Obergericht issues its own official Certificate of Service upon completion, which we deliver to your counsel.
7. Proof of service filing support. We deliver completed service documentation in the format required by your court, including court-specific cover sheets, and maintain the GPS-verified affidavit and underlying documentation for any future challenge to service validity in successor-entity or jurisdictional motions.

Compliance and Legal Framework

FRCP 25(c) — Transfer of Interest and Successor Substitution

Federal Rule of Civil Procedure 25(c) governs the procedural mechanics of continuing an action when a party’s interest is transferred. Where the transfer occurs before the lawsuit is filed — as is the case for anyone filing a new action against Credit Suisse Group AG or Credit Suisse AG today — the correct practice is to name the successor entity directly in the complaint with a factual record establishing the merger and the successor’s acquisition of the relevant legal obligation. Where the transfer occurred after the lawsuit was filed, a motion to substitute the transferee for the original party is required; courts generally grant such motions as a matter of course, but the motion must be filed before service on the transferee will be treated as effective against that party. For Credit Suisse, whether you need a substitution motion depends on when your cause of action accrued and when suit was filed relative to the two extinction dates.

Hague Service Convention — Switzerland’s Binding Objections to Articles 8 and 10

Switzerland acceded to the Hague Convention on January 1, 1995 and simultaneously entered formal objections eliminating all service methods except Article 5. The Swiss objection to Article 8 blocks direct service through diplomatic or consular agents. The Swiss objections to all sub-routes of Article 10 block postal service, service through judicial officers in Switzerland, and service through any person competent under Swiss law who is not the Central Authority. These objections are binding on U.S. courts: the Supreme Court’s decision in Water Splash, Inc. v. Menon, 581 U.S. 271 (2017), clarified that where the Convention applies and the receiving state has objected to a service method, that method is prohibited regardless of whether domestic law would otherwise permit it. Any service on UBS Group AG or UBS AG that bypasses the Obergericht is legally defective under the Convention as Switzerland has ratified it.

Obergericht des Kantons Zürich — Central Authority Procedures and Timing

The Obergericht des Kantons Zürich acts as the Central Authority for service requests directed at entities in the canton of Zurich, which includes UBS Group AG and UBS AG at their registered headquarters. Requests must be submitted on the USM-94 request form (or the applicable bilateral form), accompanied by the original documents and a complete German translation of each. The Obergericht reviews the submission for formal compliance before forwarding it for execution. Upon successful execution, it issues an official Certificate of Service specifying the date, method, and recipient. The Obergericht does not charge a fee for processing standard service requests, but translation costs, shipping, and any local execution fees are the requesting party’s responsibility. The authority’s review also ensures compliance with Swiss Penal Code Article 271, which criminalizes service acts carried out on Swiss soil on behalf of a foreign state without authorization — routing through the Central Authority provides that authorization.

German Translation Requirements for the Obergericht Submission

Every document included in an Article 5 submission to the Obergericht must be accompanied by a certified German translation. This includes the summons, the complaint, and all exhibits that form part of the documents being formally served. Documents that are referenced in the complaint but not attached may be handled differently depending on your service strategy, but the conservative and recommended approach is to include translations of every document the defendant will need to understand the claims against it and respond to the court. Use a certified legal translator — the Obergericht reviews translations for adequacy, and a substantively deficient translation is grounds for returning the request unexecuted, which restarts the four-to-twelve-month clock.

Delaware Wind-Down Entity Verification Before Service

Credit Suisse Securities (USA) LLC, Credit Suisse (USA), Inc., and Credit Suisse Holdings (USA), Inc. remain registered in Delaware, with Corporation Service Company at 251 Little Falls Drive, Wilmington, DE 19808 as the registered agent for each. Wind-down status means these entities are progressively reducing their legal footprint. Before serving, verify active Delaware registration at the Delaware Division of Corporations portal. FINRA broker-dealer registration for Credit Suisse Securities (USA) LLC (CRD 816) is a separate regulatory registration that does not confirm Delaware corporate status. A lapsed Delaware registration renders CSC service ineffective under Delaware law regardless of the entity’s regulatory filing status elsewhere.

Pricing for Serving Legal Papers on Credit Suisse

Pricing for Credit Suisse process service depends on which entity is being served and which service method applies to that entity.

Swiss Hague Article 5 Central Authority service is quoted separately based on document volume, certified translation costs, and the Obergericht’s current fee schedule. Skip trace services are $75 when a registered agent address requires independent verification. All domestic service fees include GPS-verified affidavit of service and complete chain-of-custody documentation. Contact us to discuss a combined service package if you need to serve both Delaware wind-down entities and initiate Hague transmission for the Swiss successors in parallel.

Frequently Asked Questions About Serving Credit Suisse

Is Credit Suisse still a legal entity that can be served?

Credit Suisse Group AG and Credit Suisse AG no longer exist as separate legal entities. Credit Suisse Group AG was absorbed into UBS Group AG on June 12, 2023, the closing date of the emergency acquisition orchestrated by Swiss federal authorities. Credit Suisse AG was then merged into UBS AG and ceased to exist on May 31, 2024, completing the full operational integration. Three U.S.-incorporated entities — Credit Suisse Securities (USA) LLC, Credit Suisse (USA), Inc., and Credit Suisse Holdings (USA), Inc. — remain registered in Delaware as wind-down shells and can still receive valid process service through Corporation Service Company in Wilmington as long as their Delaware registrations remain active. Verify Delaware registration status before serving any of the three entities.

Who is the correct defendant for a claim previously against Credit Suisse Group AG?

For claims against Credit Suisse Group AG, the correct defendant is now UBS Group AG as the surviving legal entity following the June 12, 2023 Swiss law merger. If your action was already pending before that date, Federal Rule of Civil Procedure 25(c) authorizes a motion to substitute UBS Group AG as the transferee party. If you are filing a new action, name UBS Group AG in your complaint from the outset and include a factual section establishing the merger date and the successor’s acquisition of the relevant liability. Your attorney should analyze whether the specific contractual, regulatory, or tort obligations you are pursuing passed to UBS Group AG under the terms of the Swiss merger agreement and applicable Swiss law, or whether they were retained by one of the surviving U.S. wind-down entities.

Can I serve UBS Group AG through a UBS United States subsidiary instead of going through Switzerland?

In almost all cases, no. Service on a domestic subsidiary of a foreign corporation does not constitute service on the foreign parent unless the subsidiary has been designated as an agent for service of process or an explicit agency relationship for that purpose can be established. Federal courts applying the Hague Convention — which controls service on Swiss entities — have held that the Convention preempts domestic service alternatives where the receiving state has entered objections to Articles 8 and 10, as Switzerland has done. The only lawful Hague route for serving UBS Group AG or UBS AG in Switzerland is Article 5 through the Obergericht des Kantons Zürich. Attempting to serve these entities through their U.S. affiliates creates a well-founded service-validity challenge that experienced Swiss-law defense counsel will raise at the first opportunity.

How long does Hague Article 5 service on UBS as Credit Suisse’s successor take?

The Obergericht des Kantons Zürich typically processes Article 5 requests within four to twelve months from the date of receipt of a complete submission. Document volume and the completeness of the German translations are the primary variables affecting turnaround time. A straightforward complaint with a single-count claim and complete certified translations moves through the system faster than a multi-volume, multi-defendant package with exhibits requiring extensive translation work. Build the full twelve-month window into your litigation schedule from the date you submit the Hague request, and advise the presiding judge of the expected timeline at the initial case management conference so discovery and responsive-pleading deadlines reflect the reality of international service.

Do I need certified German translations for every document I serve through the Obergericht?

Yes. The Obergericht will not process an Article 5 request that does not include a complete certified German translation of every document being served. This applies to the summons, the complaint, and all exhibits attached to and incorporated into the complaint. The conservative practice is to include translations of all documents the defendant will need in order to understand the claims and respond — do not assume an exhibit can be omitted because it is already available in German from another source. The Obergericht reviews translations for adequacy. A substantively deficient translation can result in the request being returned unexecuted, which resets the processing timeline and may create complications with court-imposed service deadlines.

What is the current legal status of Credit Suisse Securities (USA) LLC?

Credit Suisse Securities (USA) LLC remains registered in Delaware and holds an active FINRA broker-dealer registration under CRD No. 816 in wind-down status. As of July 1, 2025, vendor contracts formerly held by Credit Suisse Securities (USA) LLC were migrated to UBS Securities LLC as part of the broader Credit Suisse-UBS integration. The entity continues to wind down its remaining regulatory obligations and liabilities under FINRA oversight. Corporation Service Company at 251 Little Falls Drive, Wilmington, DE 19808 remains its registered agent. Service on CSC while Delaware registration is active creates valid process service for litigation purposes. Verify Delaware corporate status through the Division of Corporations before dispatching a process server to confirm the registration has not been surrendered.

What is Swiss Penal Code Article 271 and why does it matter for serving UBS?

Swiss Penal Code Article 271 criminalizes acts carried out on Swiss territory on behalf of a foreign state, a foreign organization, or a foreign party without Swiss governmental authorization. In the service-of-process context, this provision directly prohibits private service of process — a process server who travels to Switzerland and attempts to personally deliver legal documents to a company’s Swiss headquarters on behalf of a U.S. litigant is committing a criminal offense under Swiss law. This is not a technical or rarely-enforced prohibition; Swiss authorities have pursued Article 271 cases against foreign nationals who attempted to serve documents privately in Switzerland. The Hague Article 5 Central Authority route is the treaty mechanism that provides the necessary Swiss governmental authorization, placing service by the Obergericht within the treaty framework and outside Article 271’s reach.

Does Undisputed Legal handle both Delaware service and Swiss Hague submission for Credit Suisse matters?

Yes. For Delaware wind-down entity service, we dispatch to Corporation Service Company at 251 Little Falls Drive, Wilmington, DE 19808, generate a GPS-verified affidavit with timestamped location data, and deliver confirmation typically within one to three business days. For Swiss Hague service on UBS Group AG or UBS AG as Credit Suisse successors, we prepare the complete USM-94 Article 5 request package, coordinate certified German translation of all documents, submit to the Obergericht, and track the request through to the issuance of the Certificate of Service. For matters requiring both tracks — serving the surviving U.S. entities in Delaware while simultaneously initiating Hague transmission for the Swiss successors — we coordinate both in parallel so neither service timeline delays the other. Call (800) 774-6922 to discuss your matter and confirm the correct defendant identification before ordering.
