Art in a Divorce: How a Collection Is Valued and Divided

30 October 2026

Reading time: approx. 6 minutes

In short: In a Swiss divorce, an art collection is not divided at its insurance value or purchase price but at its market value at the time the marital property is settled. Three questions decide the outcome: which works belong to which spouse’s assets, what they are worth today, and how they are divided. An independent valuation, ideally commissioned jointly by both sides, saves time, cost and conflict.

Why art is a delicate asset in a divorce

Bank balances and securities have a daily price. A painting, a watch collection or antiques do not. Their value has to be established, and that is exactly where disputes arise: one side relies on the high insurance value, the other on a low auction estimate. Art is also emotionally charged. Whoever wants to keep a work has an interest in a low value; whoever is compensated, in a high one.

First question: who owns which work?

Under the default Swiss marital property regime, participation in acquired property (Art. 181 Swiss Civil Code), a distinction is made between separate property and acquired property. Simplified:

  • Separate property includes works a spouse owned before the marriage or inherited or received as a gift during the marriage (Art. 198 CC). These are not divided.
  • Acquired property includes works bought during the marriage for consideration, for example from earned income (Art. 197 CC). Their value enters the division of the surplus.
  • If it cannot be proven that a work is separate property, it is treated as acquired property (Art. 200 para. 3 CC).

This is why documents matter: invoices, inheritance agreements, gift records, insurance policies and dated photographs. Different rules apply under separation of property or community of property. Your lawyer will clarify which rules apply in your case.

Second question: what is the collection worth today?

The relevant measure is market value (Art. 211 CC): the price a willing buyer and a willing seller would agree under normal market conditions. What counts is the value at the time of the settlement (Art. 214 para. 1 CC), not the purchase price and not the date of separation. In long proceedings, the valuation may need to be updated.

Three common mistakes:

  • Insurance value instead of market value: insurance value is a replacement value and is usually well above what a sale would achieve. Using it for the division overstates the collection. See Insurance value or market value?
  • Outdated estimates: a valuation from ten years ago says little about today’s market. Art markets move very differently by artist and segment.
  • Ignoring selling costs: whether commissions, buyer’s premium or transport are taken into account is a legal question. The report should disclose its assumptions so that the lawyers can work with them.

One valuer or two?

If each side commissions its own expert, the results are often far apart and a third report follows. A single independent valuer agreed by both lawyers is usually faster and cheaper. What matters is that the valuer has no stake in the outcome: no value-based fee, no sales commission and no commission from the other side. If no agreement is reached, the court can order its own expert report.

Third question: how is the collection divided?

  • Allocation against compensation: one spouse keeps the works and pays the other’s share in cash. This requires a robust market value.
  • Division in kind: the works are split into two lots of equal value. This only works with a valuation of every single work.
  • Sale and division of proceeds: sensible when neither spouse wants to keep the works. A discreet private sale avoids the separation becoming visible through a public auction catalogue. See Selling a collection: off-market, private sale or auction?

Checklist for lawyers and clients

  1. Draw up an inventory of all works with photos, dimensions, signatures and location.
  2. Collect acquisition records: invoices, inheritance and gift documents, certificates.
  3. Clarify the marital property regime and key dates with your lawyer.
  4. Define the type of value: market value, not insurance value.
  5. Appoint the valuer jointly and agree scope, fee and deadline in writing.
  6. In longer proceedings, plan for an update of the valuation.

How I can help

I value art, watches, jewellery and antiques independently, with no commission from the other side and fees based on time spent. In divorce proceedings I work for one party, for both parties jointly or directly for the lawyers, discreetly and with clearly documented assumptions.

Frequently asked questions

Is an inherited collection divided in a divorce?

Under the default regime, inherited works are separate property and are not divided, provided the inheritance can be documented.

Which value applies: purchase price, insurance value or market value?

Market value at the time of the marital property settlement. Purchase price and insurance value are at most reference points.

Does the collection have to be sold?

No. Often one spouse keeps the works and pays compensation in cash. A sale is only one of several options.

Is the valuation kept confidential?

Yes. Reports and conversations are treated confidentially. If desired, a sale can be handled discreetly without a public auction.
