Our Essence

Tradition that renews itself, values that endure.

Martinelli Advogados Associados has built its trajectory guided by ethics, technical rigor, and personalized service. Our differential lies in deep multidisciplinary knowledge, essential for resolving complex demands that require a systemic view of Law.

We maintain as a fundamental pillar the commitment to offer close and strategic advisory. This philosophy is reflected in the direct involvement of partners in each case, ensuring solid, secure legal solutions aligned with our clients' objectives.

The Martinelli name carries more than a professional identity; it represents a legacy marked by perseverance and responsibility. Our history dates back to the immigration of Dr. Gaetano Martinelli to Brazil in 1891, whose fundamental values are preserved and transmitted through generations, shaping our way of practicing law.

Specialized in Corporate Law, Business Law and Succession Planning, we develop legal engineering capable of protecting assets and ensuring the perpetuity of family groups and corporations. We act with the highest degree of trust, discretion and full dedication to each demand.

This is Martinelli Advogados Associados: technique, tradition and proximity, always looking to the future and the projects of those who entrust us with their story.
