Frequently Asked Questions
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.
