Collaboration
Where independent voices meet in dialogue — creating connections through art, knowledge, and trust.
In 2023, Sabine Taevernier and Valérie Delfosse established a collaboration founded on shared values and complementary expertise.
While each of us continues to work independently, we join forces when a project requires a broader scope of knowledge or a multidisciplinary approach.
Our collaboration allows us to respond flexibly to specific cases and needs — combining our art-historical insight, market experience, and legal and financial understanding whenever it benefits the client.
Together, we cover a wide period, from 19th-century art to the present day, enabling us to assist collectors, art lovers, families, heirs, and institutions in making informed decisions regarding acquisition, expertise, collection management, or estate matters.
This partnership is not a fixed structure but a meeting of minds — a way to share expertise, exchange perspectives, and offer clients the most relevant and reliable guidance for every unique situation.
Sabine Taevernier
Sabine Taevernier holds a Licentiate degree in Art History (KU Leuven, 1980) and began her career as an independent curator specializing in Belgian art from the late 19th and early 20th centuries. She collaborated closely with museums in Ghent, Antwerp, Milan, Rotterdam, and Frankfurt.
From 1988 onwards, she worked as an expert at Christie’s in the departments of Impressionist, Modern, and Contemporary Art. Among other responsibilities, she oversaw the liquidation of the Galerie Isy Brachot and the sale of the pop art collection of Hubert Peeters.
Since 1998, she has been active through her own advisory practice. In 2002, she founded the Ensor Advisory Committee, and in 2005 she became a member of the Belgian Chamber of Art Experts. Between 2014 and 2024, she served as Vice-Chair of the Topstukkenraad (Flemish Council for the Protection of Movable Cultural Heritage). Since 2021, she has also been a trustee of the King Baudouin Foundation.
Valérie Delfosse
Valérie Delfosse studied Art History and Archaeology (FUNDP Namur, KU Leuven), followed by a master’s degree in Contemporary Art in London (SIA) and a management program in Antwerp (UAMS).
After four years at Galerie Meessen De Clercq in Brussels, she worked for nearly ten years as a Contemporary Art expert at Sotheby’s Brussels & Luxembourg. There, she developed extensive expertise in acquisitions, sales, collection management, and valuations.
In 2022, she founded her own advisory practice, Valerie Delfosse Art Advisory, specializing in modern and post-war art. Her practice is supported by an international network and is guided by a transparent approach. She is a member of the Belgian Chamber of Art Experts and, more recently, also a member of the pool of art experts for the Flemish Government.

2025
Belfius Art Collection
In 2025, we advised on the strategic selection and sale of works from the Belfius Art Collection, presented at Native Auction in Brussels. Our role included defining which works would be offered for sale, structuring the sale strategy, and acting as an intermediary in negotiations between the auction house and the client, with the objective of securing the best possible results while respecting the collection’s long-term vision.
The Old Master section featured significant paintings by Roelandt Savery and Theodoor van Thulden, underscoring the historical strength of the selection.
The Modern & Contemporary Art chapter traced a confident trajectory through the 20th century, highlighted by a lifetime cast bronze sculpture by Alexander Archipenko, conceived in 1913, and a striking Plaster Surrogate installation by Allan McCollum.
A focused selection of design works—primarily by Jules Wabbes and Emiel Veranneman—completed the presentation, reinforcing the collection’s dialogue between fine art and design.
