Art Cataloguing Service · Est. 2026
Ars Accordia issues permanent Artwork Passports for European private and corporate art collections — connecting each work to the institutional and public records that name it, and giving it a stable identity others can point to. Know exactly what you hold. Prove it is yours. Be ready for whatever comes. We document and anchor; we do not authenticate or value the work ourselves.
The Deliverable
A single permanent document for each work — the anchor that makes a work referenceable, citeable, and verifiable. A well-documented work is easier to insure, inherit, sell, divide, donate, or lend when the time comes. Each passport carries a permanent ArtBase ID and is listed in the public Ars Accordia registry. We do not authenticate or value the work; we anchor it.
Who We Serve
We work with private collectors, corporate holdings, and estates across Europe — anywhere art is held outside a museum and lacks the documentation it deserves.
The Process
Every engagement follows the same four-phase process — from an initial conversation to a publicly registered passport for each catalogued work.
Standards & Compliance
From the Catalogue
Published passports from the Ars Accordia catalogue — each catalogued to the standards above, with authority links and permanent identifiers.

Tell us what you hold — approximate size, period, and the moment you are preparing for: an insurance renewal, an inheritance, a potential sale, a loan programme, a division among heirs. We will assess what the collection needs and propose a scope at no obligation.
