Welcome to the new ASD LEGAL INFORMATION HUB. We are redesigning the website of our law firm. We have cooperated closely with experienced designers, programmers and user experience specialists to create a new cosmos of websites in which every user can find systematic and intelligently processed information.

Under the button “ABOUT THE INFORMATION HUB” you can find out how our new information system works.

You can count on us

As a law firm with more than 100 lawyers, notaries and tax advisors, ARNECKE SIBETH DABELSTEIN offers legal advice in all relevant business locations.

We are one of the leading law firms in Germany with offices in Frankfurt, Hamburg, Berlin, Leer and Dresden and are internationally recognised market leaders in the areas of real estate, transportation/aviation/logistics and maritime industry. We are also continuously growing in the energy, insurance, technology/media and sports law sectors.

Our legal practice areas include labour/employment, Insurance, corporate/m&a, banking & finance, intellectual property, IT, commercial, public and antitrust. We also have a tax team and a notary's office.

Due to our memberships in global legal networks (e.g. Interlaw, Legal Netlink Alliance) as well as worldwide contacts to specialised law firms, we are also a reliable partner for international clients.

We are in Law

ARNECKE SIBETH DABELSTEIN represents a 90 year old history of a dynamic and future oriented working approach. With over 100 enthusiastic lawyers, some of them with international awards, and with our excellent notary office and tax law team, we are now one of the most important full-service business law firms in Germany.

The global pandemic at the beginning of the 2020s accelerated the necessary change. This also effects us – both as a responsible employer and as a provider of progressive legal services. We are aiming to be digital, faster and sustainable in all of our actions.

As an “employer in transition”, we discuss with our staff what the “law firm of the future” should look like. At the same time, we aim to strengthen our digital competence in our 25law segments.
This means, for example, that we can react quicker to enquiries and that we also have greater opportunities for forward-looking consultation because we can identify topics for the future at an earlier stage.
In addition, we are constantly working on new areas of consulting, such as ESG (environmental, social, governance) and aim to underline our claim to be sustainable both internally and externally.

Our corporate culture of flat hierarchies, open doors and respectful and unprejudiced relationships is part of our history. ASD always was – and still is – open-minded and future-oriented. We want to strengthen this approach in our transformation process.

Open by nature

We stand in a long tradition. In the era of steam-powered shipping we already advised shipping companies, shipyards, importers and exporters, and we were recognised as specialists for shipping, transport and insurance law. Today we are among the leading national and international law firms for the maritime industry, transportation, aviation & logistics. In the real estate segment we also embraced both tradition and modernity at an early stage, and we have long been one of the leaders in Germany and Europe.

The transformation to a large and modern full-service commercial law firm, which now covers 25 areas of law, was completed by the merger of three medium-sized law firms: Dabelstein & Passehl, Hamburg (founded in 1930), Arnecke Siebold, Frankfurt (founded in 1995) and Sibeth, Munich (founded in 2005).

Our legal services now cover topics such as employment law, corporate, finance, M&A, IP, IT, commercial, public law and antitrust law. We also have a tax law team and a notary office with locations in Hamburg, Frankfurt, Berlin, Leer & Dresden.

Our teams are inter-disciplinary, serve different segments of commerce and industry and are very well networked. With our long-standing membership of exclusive law firm networks, such as Interlaw, we are a reliable partner for both national and international clients in all relevant areas of law.

Collaborative, communicative, open minded

At ARNECKE SIBETH DABELSTEIN we maintain short communication channels and shallow hierarchies. Our two managing partners are supported by four specialist departments (Finance, Communications, Human Resources and IT) and the office managers in the individual locations.

The ASD LEGAL INFORMATION HUB consists of a modular web network which is sub-divided into three systems:

  1. EARTH:
    Our main page is the heart of our ASD LEGAL INFORMATION HUB

    Here you can find all the basic information about our law firm. We also offer a rapid and clearly structured introduction to our areas of law, experts, locations, the latest news and events and the career opportunities in our law firm, and you no longer have to click your way through many different sub-levels and complicated menu structures.

    Every area of law has its own website

    You can use sub-domains to gain direct access to the subjects you are interested in without having to navigate the complicated route via the main page. You will quickly find the information you are looking for. In the future, more STARS will be added with topics such as “INTERNATIONAL DESKS” or “WOMEN IN LAW”. Our cosmos is alive, and it is constantly expanding.
    The digital business cards of our experts

    For each area of law there are landing pages with individual information about our lawyers, their specialisations and teams and other interesting information. They are the digital business cards of our experts.

This whole cosmos of information is connected and provides links to our external social media platforms such as LinkedIn, Xing, Youtube, Soundcloud, Talentrocket, the platforms and websites of our partners.


Our advisory and support services are sustainable, comprehensive and transparent: We show our clients the opportunities, risks and consequences in every situation - realistically and pragmatically. This includes a reliable assessment of the legal and procedural situation, the expected financial, temporal, personnel and also emotional challenges of legal disputes.

We manage state court proceedings as well as national and international arbitration proceedings. With our worldwide network, we also coordinate proceedings across borders. We represent clients in association court proceedings as well as mediation and other dispute resolution proceedings. Our 25 legal segments offer you assistance in all relevant business areas.

Things can be as simple as that: ASD combines a wide range of legal expertise with around 100 passionate lawyers. Simply enter the name of the lawyer and/or the location or area of law for your request and the first contact is already made.

Use our news hub and you will always be well informed. We are happy to share our knowledge about current developments in all areas of business law and the latest information from our 18 special legal fields with you.

German trademark "MVP" canceled due to lack of distinctiveness

In Germany, waves of warning letters have become a nuisance to which SMEs in particular are exposed. Traditional infringements of competition law, such as sanctioned formal defects, have often been the target of warning letters. Now that the legislator has raised the hurdles for warnings under competition and copyright law, new areas are increasingly being […]

ASD 42bit - Folge 8 „CCaaS (Cybercrime-as-a-Service)“

CCaaS (Cybercrime-as-a-Service) oder AaaS (Access-as-a-Service) einkaufen? Cyberkriminalität ist zu einer arbeitsteiligen Industrie geworden. Ist es nur eine Frage der Zeit, bis ein Hacker nicht nur anklopft, sondern im eigenen System ist und Daten klaut oder die Dateien verschlüsselt? Wie sollte auf einen Angriff reagiert werden? Ist die Zahlung eines „Lösegelds“ der richtige Weg? Hierüber sprach […]

ASD 42bit - Folge 7 „Datenzugang: Der kartellrechtliche Weg“

Daten sind zu einem entscheidenden Wettbewerbsparameter geworden. Der Podcast 42bit befasste sich bereits mit der „Datenhanse“ mit dem einvernehmlichen Weg des Datenaustauschs zwischen Unternehmen. Sollte sich ein Unternehmen aber weigern, bleibt vielleicht noch der Weg des kartellrechtlichen Herausgabeanspruchs. Hierüber sprach Thomas Fischer, Leiter des Bereichs DIGITAL TECHNOLOGIE bei ASD, mit seinem Partner Dr. Sebastian Jungermann […]
