Interview Highlights

Can you share the story behind the inception of DPZ Avocats in 2011? What inspired the creation of a firm focused on tax management and litigation, and how has the vision evolved over the years?

When I founded DPZ Avocats in 2011, my goal was not to build just another law firm. My mission was to create a place where businesses could feel protected, supported, and empowered in front of one of the most intimidating powers they face: the State.

From the start, I wanted clients to know they would not face tax and criminal law alone. My vision was to stand beside them, not above them, to co-pilot every decision and bring clarity to an increasingly uncertain climate. Over the years, this vision has taken on a very specific energy: DPZ is a firm of audacity, resilience, and feminine leadership.

We are not afraid to challenge authority. If defending a client means questioning the Constitution before the Conseil Constitutionnel, we do it. If the tax administration abuses its powers, we hold the State accountable. Our role is not limited to advice—we exist to protect, to fight, and to give our clients the confidence to move forward.

DPZ Avocats offers a wide range of services, from daily tax management to complex transactions and litigation. Could you highlight the key services that set DPZ apart in the competitive legal and tax advisory landscape?

Our services cover the full spectrum of tax law, but what sets us apart is the way we deliver them.

• Co-piloting with clients: Every client is accompanied directly by me and a senior lawyer, ensuring they always benefit from both strategic vision and deep technical expertise.
• Objective-driven support: We do not count hours. Instead, we set clear objectives for a three-month period and commit fully to achieving them, staying in regular contact and adapting as needed.
• Legal certainty through advance rulings: Since 2018, advice alone is not enough. We go further, obtaining official advance rulings (rescrits) to secure our clients’ positions and give them true legal protection.

This unique mix of fearlessness and security defines DPZ’s DNA. We push boundaries, but we anchor our strategies in solid legal ground.

DPZ emphasizes making fiscal strategy accessible to businesses at all stages of development. How does your firm ensure that small and medium-sized enterprises, not just large international groups, benefit from sophisticated tax strategies to gain a competitive edge?

We believe tax strategy should never be a privilege reserved for multinationals. SMEs and entrepreneurs deserve the same level of sophistication—sometimes even more, because agility is their strength.

For us, accessibility means:

Clarity: translating complex laws into simple, actionable steps.

Time-saving: freeing clients from endless technicalities so they can focus on growing their business.

Premium, tailored offers: scalable packages that evolve as clients grow, always designed around their reality.

Our clients—whether small businesses or global groups—leave our meetings feeling not only advised, but empowered, with their decisions secured and their vision strengthened.

How does DPZ proactively manage tax-related risks from regulatory changes and cross-border operations to help clients thrive as “Best Companies to Watch 2025”, avoiding costly tax adjustments or litigation?

We live in an era where uncertainty is constant. Tax law evolves rapidly, authorities grow more assertive, and cross-border risks multiply. Clients cannot afford to simply react—they must anticipate.

At DPZ, we track every regulatory shift in France, Europe, and beyond. We immediately translate these changes into practical strategies, adjusting before risks turn into disputes. In cross-border cases, we rely on our international network of trusted partners, ensuring our clients always have both local expertise and a global vision.

And when disputes do arise, our approach is fearless. If the tax administration oversteps, we do not hesitate to challenge it—even in the highest courts. Our clients know we will defend them with both precision and courage.

Your firm highlights reconciling innovation with durability in business decisions. How does DPZ integrate sustainability principles into its tax and legal advisory services to help clients achieve long-term success?

We believe innovation without durability is fragile. At DPZ, we integrate sustainability into every strategy—financial, legal, and human.

This means building tax structures that last, leveraging incentives for green investments, aligning governance with ESG principles, and ensuring that decisions made today remain valid tomorrow.

Our philosophy is simple: we do not design quick wins; we design foundations that stand the test of time. That is how our clients can innovate boldly, knowing their structures are robust and their future secure.

As a partner of NEXIA International and a member of the International Fiscal Association France, how does DPZ leverage its global network to support clients in cross-border transactions or international tax disputes?

Globalization has transformed taxation into a global game. Our clients cannot be confined to national solutions.

Through NEXIA International, we connect our clients with expertise in more than 125 countries, ensuring they are supported wherever they expand. As members of the International Fiscal Association, we remain at the forefront of global tax policy and jurisprudence.

This dual network gives our clients the best of both worlds: the closeness and agility of a boutique firm, combined with the reach and resources of a global alliance.

What exciting plans does DPZ Avocats have for the future, particularly in terms of expanding services, geographic reach, or technological innovation, which your clients and partners should look forward to in 2025 and beyond?

At DPZ Avocats, technology is a tool, never our positioning. The essence of our future lies elsewhere: in human presence, international reach, and all-in support.

The international dimension will always be our key. Tax and criminal law increasingly demand strategies that cross borders. That is why we continue to strengthen alliances with leading international business crime lawyers, ensuring our clients are protected worldwide.

Beyond law, we are creating all-in, holistic forms of accompaniment. One example is our Séjours Écrin—exclusive retreats designed especially for women leaders. Traditional networks often fail to address their realities. These retreats offer a new kind of space: combining sophisticated tax and wealth strategies with tools for clarity, peace, and even better sleep. True leadership requires strength, but also serenity.

Our ambition for 2025 and beyond is simple: to remain a firm of audacity, empowerment, and vision—always giving our clients the power to move forward with confidence.

Delphine Parigi | In Her Own Words

I am Delphine Parigi, Founder and Managing Partner of DPZ Avocats. For over 20 years, I have dedicated my career to defending businesses and entrepreneurs against uncertainty, and to turning tax law into a lever for empowerment rather than a source of fear.

My leadership is both feminine and fearless. I co-pilot every mission with my clients, always alongside a senior lawyer, so they know they are fully supported—strategically, technically, and humanly. I am present, I listen, and I act.

I am not afraid to confront authority. When necessary, I bring constitutional questions before the Conseil Constitutionnel. When the administration abuses its powers, I hold the State accountable. For me, being a lawyer is not just about advising—it is about protecting, empowering, and at times, fighting.

I am also passionate about supporting women leaders. This is why I created the Séjours Écrin, retreats where women can access tailored wealth strategies and leadership support outside of traditional networks. These spaces combine legal expertise with personal well-being, restoring clarity and balance—because leadership also requires peace.

This blend of technical mastery, vision, and audacity defines me as a leader—and defines DPZ Avocats.
