A firm of excellent technical quality and client service. Demarest is definitely one of the law firms I most enjoy working with and trust. Their litigation team is practical and objective, without ever compromising on technical quality.
Demarest stands out for its deep understanding of our business, incorporating factual aspects into the final work that contribute to the success of each litigation case, including a unique way of assessing risks and creating layers of security for legal matters. One of the firm’s main differentiators is the value it adds to the business, which it does masterfully, whether through sector knowledge or careful risk assessment.
Technical excellence, a multidisciplinary team, and a strategic approach (especially in highly complex litigation cases involving significant amounts and major commercial impacts) are some of the strengths that set Demarest apart. The direct involvement of partners in defining case strategy ensures depth, agility and security in handling matters. The firm is also distinguished by its close relationship with clients and its genuine willingness to support internal discussions and provide legal insights that add real value to decision‑making.
