Emma and Louis founded the agency after several years of experience as real estate lawyers, both in France and internationally. They remain deeply involved in managing a significant real estate portfolio in Paris within the historic family real estate management company and their family office.

Emma holds a law degree from University College London (UCL) in the United Kingdom, while Louis graduated from Dartmouth College in the United States.

Fully bilingual, they combine in-depth legal expertise with a refined understanding of the French historic property market.

Winthorpe stands out for its bespoke approach, discreet network, and thorough command of legal, tax, and cultural considerations — particularly for a discerning international clientele.

Specializing exclusively in off-market sales (private mansions and châteaux) we guide our clients with discretion, precision, and dedication — from the very first visit through to final signature at the notary’s office.

Beyond the purchase, we continue to support our clients with all post-acquisition formalities, whether dealing with property management companies, tax authorities, urban planning departments, or the Ministry of Culture—just as a family office would for its French clients.

You will enjoy the dedicated support and expertise of the Winthorpe Family Office.

This exclusive and unique service in France, tailored for our international clientele, allows you to fully enjoy your properties in France while keeping peace of mind.
