A family office is an independent structure that supports wealthy families in the comprehensive management of their wealth. A true long-term strategic partner, it acts as a coordinator, ongoing auditor, and guardian of overall asset coherence — going beyond purely financial aspects.

Its areas of expertise include:

• financial management,
• legal and tax structuring,
• family governance,
• wealth transmission,
• and philanthropic projects.

There are two main types:

• the single-family office, dedicated to a single family,
• the multi-family office, which pools resources to support several families.

MJ&Cie, the first independent multi-family office founded in France in 2001, supports a deliberately limited number of families with a selective, tailor-made, and human approach.

Choosing MJ&Cie means choosing:

• a trusted, independent partner,
• a 360° vision — human and wealth-oriented,
• sustainable optimization that generates savings,
• better risk management,
• and more time and peace of mind to focus on what truly matters to you.

Our contracts are open-ended, with a three-month notice period. The relationship is designed to last, yet remains free and flexible.
