Setting deaccessioning policy basics for a small museum

What is a deaccessioning policy and why does every collecting institution need one?

A deaccessioning policy is the written procedure a museum follows to remove an object permanently from its collection, whether by transfer, exchange, sale, or in rare cases destruction. The American Alliance of Museums (AAM) frames deaccessioning as part of a museum's collections stewardship duties under its Code of Ethics for Museums, which asks institutions to act in the public trust and to use any proceeds from the disposal of collections only for the acquisition or direct care of other collections, never for operating costs (AAM, ethics, standards and professional practices). Without a written policy, decisions get made object by object, under pressure, and without a record that a future director or auditor can review.

A policy does not need to be long. It needs to answer, in advance, who can propose a deaccession, what criteria apply, who approves it, and where the proceeds can go.

Who should be allowed to propose and approve a deaccession?

Separate the person who proposes a deaccession from the person who approves it. A curator or collections manager typically identifies a candidate object and documents the reasoning; a collections committee or board reviews the case; the director or board gives final approval for anything leaving the permanent collection. This separation protects both the object and the staff member, since no single person can quietly remove an item without a paper trail that a later reviewer can reconstruct.

Record the vote, the date, and the names of those present. A policy that is silent on approval authority invites disputes later, especially if a donor or the press asks why an object left the collection.

What criteria justify removing an object from the collection?

Common, defensible criteria include:

Criterion	What it means
Outside mission or scope	The object no longer fits the institution's collecting plan
Duplication	The collection holds a stronger example of the same type
Poor condition beyond repair	Conservation cannot return the object to usable or exhibitable state
Lack of provenance or authenticity	Research cannot establish what the object is or where it came from
Inability to care for it properly	Storage, security, or environmental conditions cannot meet the object's needs
Legal or ethical obligation	Repatriation, restitution, or a court order requires transfer

An object rarely fails on only one criterion. Document each one that applies, because a thin justification is the first thing a later reviewer, donor, or journalist will challenge.

What should never drive a deaccession decision?

A deaccession should never be driven by a short-term need for operating revenue. AAM's Code of Ethics is explicit that any proceeds from disposal of collections must go back into the collection, through acquisition or direct care, not into salaries, utilities, or general operations (AAM). A policy that permits revenue use outside those limits puts the institution's accreditation and donor trust at risk, since donors give objects expecting they will be cared for or used for the museum's mission, not sold to cover a budget shortfall.

If your institution is weighing a sale for financial reasons, treat that as a governance question for the board and legal counsel, separate from the ordinary deaccession review described here.

How should rights, restrictions, and donor conditions be checked before approval?

Before any object moves toward deaccession, check the accession file for deed of gift language, donor restrictions, and any conditions attached to the original transfer. Some gifts carry a condition that the object return to the donor's family or another named institution if it is ever deaccessioned. Legal review is appropriate whenever restrictions are unclear or the object has a complicated ownership history. This step connects directly to the broader practice of maintaining accurate minimum record fields for a collection, since a record missing acquisition details makes this check far harder.

What disposal methods are available once a deaccession is approved?

Once approved, common disposal methods include transfer to another nonprofit collecting institution, exchange with a peer museum, sale through a reputable auction house or dealer, or, only when no other option exists and the object has no research or exhibition value, destruction. Transfer to another public institution is generally preferred because it keeps the object within public trust and accessible for future research or display. Document the method chosen and the recipient in the permanent record, and update the catalogue so the object's departure is traceable rather than simply absent.

How should a deaccession be documented for the permanent record?

Keep a deaccession file for each object containing the proposal, the criteria checked, the committee vote, board or director approval, the disposal method, the recipient or buyer, and the date completed. This file should be as durable as the original accession record. A future registrar auditing the collection should be able to reconstruct exactly why an object is no longer present and where it went, the same way they would trace an object's history through a condition report or a catalogue entry.

What is the first step to building this policy if one does not exist yet?

Start by drafting the approval chain and the proceeds-use rule, since those two elements carry the most public trust risk. Add the criteria table once the approval chain is settled, then circulate the draft to the board and legal counsel before adopting it formally. Review the policy whenever your institution changes its collecting scope, since mission drift is one of the most common reasons an object later needs review.

A deaccessioning policy is not a tool for shrinking a collection quickly. It is a safeguard that lets a museum make a small number of well documented, defensible decisions over time, and shows every future reviewer exactly how and why each one was made.
