What We Do

Phillips Fiduciary Services draws on extensive experience in structuring financial arrangements, such as advances, loans, minimum price guarantees, and risk sharing agreements in connection with the acquisition or disposal of high-value artworks. We can tailor these arrangements to suit your client’s needs, and we pride ourselves in ensuring our agreements are clearly presented.

Private sales offer the possibility of selective, discreet sales of art in which we match buyers to sellers. Our Fiduciary Services team has been instrumental in private sales at world-record prices, and we can help your client to acquire or sell important artworks privately in collaboration with the Phillips Private Sales team.

Like any unique asset, artworks can sometimes be encumbered with problems requiring a pragmatic solution. Our team can offer you the benefit of our problem-solving expertise, assisting you with questions relating to:

  • Authenticity and misattribution
  • Holocaust restitution claims
  • Cultural property restitution claims
  • Copyright issues
  • Endangered species/CITES issues
  • Import/export issues

There are a few select and very technical areas where we don’t have the relevant expertise—yet even in those rare cases, we can help you to find a leading expert in areas requiring specialist knowledge. These include:

  • Tax experts
  • Forensic experts
  • Authentication Specialists
  • Insurance experts

The Fiduciary team has extensive experience operating throughout the world in many different jurisdictions. While we are permanently based in London and New York, our team members are very comfortable working with clients and lawyers all over the world, and do so regularly. Many of the team are multilingual, have overseas legal qualifications and are comfortable working in English, German, Spanish, and French.

When advising a collector, an estate, or a trust with an art collection, the starting point is always to understand the financial value of the collection. This may be required for a variety of purposes including insurance, financial planning, estate tax, charitable donations, and gift tax. That value can fluctuate and is determined by a variety of factors more nuanced than simply supply and demand; these include provenance, condition, attribution, rarity, and evolving taste. Drawing on the knowledge of Phillips’ specialists, our Trusts, Estates and Valuations team can assist in providing you with valuations of your client’s artwork or collection of artworks.
