Adaptive thinking is the firm’s tool of choice when it comes to staying relevant for clients. This subtle art is all about learning how to think instead of being taught what to think.

At NautaDutilh, we aim to meet our clients’ needs, contribute to their success and create an inspiring and challenging working environment for our employees. We embrace independence and integrity towards our clients, employees, stakeholders and society at large.

Taking responsibility for the effects of our activities from a social, ecological and economic perspective is a fundamental part of how we think and act. We are firmly rooted in society and actively contribute to the way it functions, based on our specific competences and our diversity, in a way that is true to our character. That same mission was of equal importance to one of our founders, Tobias Asser, who won the Nobel Peace Prize in 1911.

Today, we are involved in and support a wide range of activities, such as the Lawyers for Lawyers Foundation where we sit on the board, and are the exclusive legal advisers to the SI² fund, which invests in innovative, socially responsible companies. We also participate in Pro Bono Connect and are among the 13 law firms that support the public interest clearinghouse. We set aside time to contribute to new legislation and regulations through consultation procedures, and encourage the relatively large number of academics in our ranks to take part in them. In addition to various internal initiatives, many of our people are active in political, social and/or cultural activities and events outside of work.

Sustainable development has always been high on NautaDutilh’s list of priorities. The Think Green Committee has played a key role in fostering environmental awareness within thefirm since 2004. The committee’s aim is to raise environmental awareness through actionswhich involve everyone, such as the reduce of paper and energy consumption and the useof public transport or bike.

Diversity Committee
We are firmly convinced of the benefits of a diverse workforce. It has been on our priority list since 2001. A more active approach was taken in 2005 by the establishment of a firmwide Diversity Committee. Together with other law firms, we’ve also created the Women in Law (WIL) Program, a training program for young female lawyers intended to improve their soft skills and provide them with the tools they need to succeed in the legal profession.

Children and Law
We are especially dedicated to playing an active role in society for children who have poor access to ‘law’. One of the organisations we support in this light is KidsRights, which promotes the well-being of vulnerable children across the world and advocates for the realization of their rights. We also support JINC, giving young people a better chance for the future, and introduce children from underprivileged neighbourhoods to the concept of ‘law’ at the IMC Weekend School. We also provide legal services the Kindertelefoon (Child Helpline) on a pro bono basis.

NautaDutilh’s New York office advises clients on the Luxembourg, Dutch and Belgian legal aspects of US-originated or US-coordinated cross-border banking, finance and corporate M&A transactions. We have excellent capabilities in the full range of banking and financial services, including (debt and equity) capital markets, structured finance, securitization structures, financial products, securities legislation, international finance, leveraged lending, acquisition finance, fund finance, and insolvency and restructuring. The clients of our New York office are mainly US-based financial institutions, asset managers, large and mid-sized corporates, private equity firms and fund sponsors. We also work closely with top US law firms, with which we have developed strong ties, on complex cross-border matters for their clients.

We distinguish ourselves by:

  • a primary focus on US transactional practice;
  • an in-depth understanding of the challenges facing our clients in the US business and legal environments;
  • availability for our clients in US time zones;
  • a full-service corporate, finance and capital markets team with tax and administrative support in New York, backed by specialists and additional staff in our Benelux offices, to meet our client expectations and deadlines;
  • serving as a gateway to full-service expertise in Luxembourg, the Netherlands and Belgium.

Jad Nader (Ph.D.), partner and head of the Luxembourg Desk in New York, brings Luxembourg banking financial and corporate law expertise to the New York office, promoting the Luxembourg office and accompanying US clients on their Luxembourg activity. Many of our Luxembourg banking and finance associates rotate through the New York office to obtain relevant “on the ground” experience in US transactions. Our lawyers are active members of key Luxembourg-US organisations for financial and legal sector professionals such as the American Chamber of Commerce in Luxembourg (Amcham), the American Bar Association (ABA), the New York City Bar Association and the New York State Bar Association, which allows them to stay informed of upcoming legislative and regulatory changes. Our lawyers are appreciated for their availability, experience, solution-driven attitude and proven legal expertise.

We advocate a multi-disciplinary approach and have an excellent track record representing US financial institutions and corporates. Representative transactions for our US clients include:

  • assisting international banks and direct lenders with leveraged lending (secured cross-border credit facilities), ABL transactions, subscription line financing transactions and structured finance;
  • advising major investment management firms on regulatory issues and the setting up of Luxembourg structures;
  • assisting international banks and corporates in major acquisition finance deals;
  • advising international banks and multinational financial services companies on regulated M&A, governance, financial and corporate issues;
  • assisting issuers and underwriters with the issuance and listing of bonds.
