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.
We support French and international families and entrepreneurs who are keen to
structure, enhance, secure and transfer their wealth.
Our approach combines:
– in-depth technical expertise,
– a keen understanding of family dynamics,
– and preparing new generations for their responsibilities.
As entrepreneurs ourselves, we also ensure seamless coordination between private wealth
and professional interests through our corporate advisory services.
MJ&Cie operates in five main areas:
- Investment advice: strategy, supervision, selection of service providers, consolidated reporting (listed and unlisted assets, real estate, art, etc.).
- Legal and tax structuring: asset organisation, selection and coordination of experts.
- Family & Governance: succession planning, mediation, governance, family projects, philanthropy.
- Corporate advisory: financing, partnerships, real estate projects, banking relationship management.
- Private secretarial services: administrative management, personal accounting, day-to-day logistics.
A private bank distributes its own products, often with a limited view of the client’s assets.
A wealth management adviser deals with more modest assets, with remuneration sometimes linked to retrocommissions.
MJ&Cie acts independently, without selling products, with a comprehensive view and decisions taken in the exclusive interest of its clients.
Yes we do. We work closely with the family’s advisers (solicitors, lawyers, accountants, etc.) to ensure overall consistency. If necessary, we select new experts through a tender process.
Only transparent, fixed fees, agreed in advance with our clients. This guarantees our independence and the absence of any conflicts of interest.
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.
We assist families with complex assets (legal, family, professional, etc.), going well beyond purely financial considerations. Our fees are adjusted to the nature of the project, with high standards ensured by a limited selection of clients.
No, but if needed, we identify and select the best service providers. Our private secretarial service covers administrative, accounting, real estate, and personnel management.
