Authentication Committee


Due to the health situation and the French government's recommendations against Covid-19, the Fondation Giacometti offices are closed until further notice. All demonstrations and events are postponed to a later date. In view of this situation, the entire Fondation Giacometti team remains available by e-mail to answer you as soon as possible.

The Giacometti Committee is comprised of all of Alberto Giacometti’s beneficiaries:

- the Fondation Giacometti, Paris
- the Alberto Giacometti-Stiftung, Zürich (Alberto Giacometti Foundation, Zurich)
- the heirs of the late Silvio Berthoud ("the Berthoud estate")


The Giacometti Committee verifies the authenticity of works by Alberto Giacometti submitted to it (paintings, sculptures, drawings and decorative art objects) and delivers certificates of authenticity or expert opinions.

The Giacometti Committee oversees the restorations of the artist's works in order to ensure the respect of the integrity of the works. 

The seat of the Giacometti Committee is at the Fondation Giacometti in Paris.
