About the firm

An independent firm with a cross-border instinct.

We built Lex Mundi Partners around a simple idea: clients working across the United States, the Gulf, Türkiye and Europe deserve one coherent team, not a chain of introductions.

Our story

Founded in California. Shaped by three markets.

Lex Mundi Partners was founded in Twentynine Palms, California, in 2009 by a small group of lawyers who had spent their careers moving between the United States, the Gulf and Europe. They saw the same problem repeatedly: international clients were being advised in fragments, with each jurisdiction treated as a separate conversation.

The firm grew deliberately. An Istanbul office followed in 2014, and Madrid in 2018, each led by lawyers with deep roots in the local market. Today the three offices operate as a single practice, sharing clients, matters and standards.

We remain independent and privately held. That independence allows us to recommend what is right for the client without conflicts or referral pressures — and to turn down work that we cannot do exceptionally well.

Our values

What we stand for

Four commitments that shape how we work, hire and advise.

Judgement over volume

We take on fewer matters so that each one receives the attention it deserves.

Fluency across borders

We understand how law, culture and commerce interact in each of our markets.

Partnership in practice

Clients work directly with senior lawyers, not a layer of intermediaries.

Discretion as standard

We protect our clients’ confidence in everything from staffing to filing.

“The best cross-border advice is not a summary of three legal systems. It is a single recommendation that understands all three.”
