The Forgotten Asset: Why Art Must Be Part of Every Estate Plan

Art now sits at the heart of private wealth, emotionally, culturally and financially. Yet when it comes to estate planning, it remains one of the most neglected assets.

According to insights from the Deloitte Art & Finance Report 2025, 81% of wealth managers reported integrating art into estate plans, more than double the figure from 2017. But behind this progress lies a disconnect. Most heirs remain uninformed, under-documented and unprepared for what they will inherit.

The Importance of Art Estate Planning

Art’s inclusion in estate planning reflects a major shift in how wealth is defined and protected. Yet as institutional adoption increases, many private collectors have yet to formalise their processes, exposing families to unnecessary risk.

Too often, artworks are mispriced through over-reliance on auction comparables, which can result in over- or under-insurance. Valuations are rarely refreshed, provenance records may be incomplete, and essential documentation can disappear during ownership transitions.

These issues can lead to delays, disputes and avoidable tax exposure. A structured, independent approach ensures every piece is correctly recorded, valued and insured.

Regular, independent art valuations protect beneficiaries and fiduciaries, ensuring each work of art is properly documented and transferred. This approach safeguards both capital and continuity.

Why Art Estate Planning Matters for Families

For families, the question is not only how much their art is worth but how well it is managed.

• Reduce disputes and delays. Accurate records and up-to-date valuations help prevent confusion, conflict and unnecessary legal costs during estate transitions.
• Protect against loss. Detailed provenance and condition reports ensure insurance coverage reflects the real value of the collection.
• Plan philanthropy with intention. Charitable gifts and museum loans work best when eligibility, timing and valuation are known in advance.
• Enable adviser coordination. Accurate data allows lawyers, wealth managers and insurers to collaborate efficiently, protecting both assets and family harmony.

When managed properly, art preserves financial value while strengthening family legacy.

From Passion to Preparedness: Building a Lasting Legacy

For many collectors, art is the most personal line item on the balance sheet. Without structured planning, however, it can also be the most complicated.

By combining documentation, valuation and estate strategy, families can ensure art continues to connect generations instead of dividing them.
