What is Thomas Thorup’s professional background?

Thomas has more than 20 years of experience as a business attorney and litigator. For the past 15 years, he has worked primarily with Danish American businesses on cross-border and U.S. legal matters, drawing on years spent living and working as an attorney in the United States before returning to Copenhagen.

What makes his qualification unusual?

Thomas is admitted to practise before both the Danish and the U.S. Supreme Courts — currently as the only attorney in the world holding that specific combination. That dual admission means Danish-American matters can be handled by one lawyer who is genuinely qualified in both systems, rather than split across two separate firms.

What does he work on?

His practice covers U.S. corporate setup, formation and administration, U.S. and cross-border contracts, international dispute resolution and arbitration, U.S. trademark registration, business visas and general U.S. legal advice for Danish and international clients.

Where is he based?

Thomas is the founder and owner of Thomas Thorup Law and is mainly based at Rosenfalck & Thorup’s Copenhagen office, after many years living and working as an attorney in the United States.
