Guidelines on Deaccessioning of theInternational Council of Museums
Introduction
The following guidelines elaborate upon the principles of the ICOM Code of Ethics forMuseums concerning the deaccessioning and disposition1 of objects2 from museum
collections. The guidelines consider deaccessioning within the context of acquisition
and accessioning and are intended to assist in the practical application of the Codeof Ethics’ principles.
Acquisition
The decision to acquire an object (whether it is offered for donation, acquired at saleor auction or found during an archaeological excavation) and accession it into amuseum’s collection should be made thoughtfully, considering the nature of theobject and its provenance, the museum’s mission3 and the resources that will berequired to care for, display and provide access to the object. A museum’s collections
policy should thoroughly define the acquisition process and address the legal andethical principles and professional responsibilities involved4.
Acquisitions should be made in accordance with the highest standards of due
diligence5 and in accordance with the applicable law6.
Accessioning
Once a museum acquires an object, the object is accessioned. Accessioning is theformal process involved in accepting and recording an item as an object in amuseum’s collection and its inventory. A record of the acquisition, accession
processes, and all relevant documents accompanying the object should be kept andpreserved.

In the ICOM Code of Ethics for Museums, the term “disposal” is used instead of “disposition”.
For the purposes of these standards, the word object is used broadly to refer to all cultural objects, as defined in the relevantinternational legislation: cultural objects are those which, on religious or secular grounds, are of importance for archaeology,prehistory, history, literature, art or science.

2Guidelines on Deaccessioning of the International Council of Museums

Deaccessioning
Deaccessioning is the act of lawfully removing an object from a museum’scollections.
Where the law does not prohibit a museum from de-accessioning, a museum might
consider deaccessioning an object from its collection for one of the following reasons:1- The physical condition of the object is so poor that restoration is not practicable orwould compromise its integrity. Objects that are damaged beyond reasonablerepair and are of no use for study or teaching purposes may be destroyed.
2- The object poses threats to health and safety to the staff and the public.
3- The museum is unable to care adequately for the object because of its particularrequirements for storage or conservation.
4- The object is a duplicate that has no added value as part of a series.
5- The object is of poor quality and lacks aesthetic, historical and/or scientific value
for exhibition or study purposes.
6- The authenticity or attribution of the object is determined to be false or fraudulent,
and the fraudulent object lacks sufficient aesthetic, historical and/or scientificvalue to warrant retention. In disposing of a presumed forgery, the museum shallconsider all related legal, curatorial and ethical consequences, and should avoid
returning the object to the art market.
7- Another museum could more appropriately care for, display and provide access tothe object, and it is the intention of the originating museum to assign ownership of
the object to that other museum
8- The museum’s possession of the object is inconsistent with applicable law orethical principles, e.g., the object was, or may have been, stolen or illegally
exported or imported, or the object may be subject to other legal claims for returnor restitution.
9- The object is no longer consistent with the mission or collecting goals of themuseum.
10- The object is being sold as part of the museum’s effort to renew and improve its
collections, in keeping with the collecting goals approved by the museum’sgoverning body.
In no event should the potential monetary value of an object be considered as part ofthe motive for determining whether or not to deaccession.
Prior to making the decision to deaccession, the legal status of the object should bereviewed, so that the museum can determine that it can deaccession the object
within its legal and ethical principles. The following should be considered:

the object’s authenticity,
the object’s legal status of ownership,
any restrictions made by the donor of the object,
all the available provenance of the object, including prior ownership, sale,exhibition and import/export history
any other conditions and restrictions made at the time of acquisition.

If, however, there is no documentation on the provenance of an object in a museum
collection, including donor documentation, the object should only be deaccessioned if
research on the object’s provenance has been exhausted in a reasonable manner. In
case of deaccession, the information that there is no provenance record to the object
should be given with the object in order to guarantee transparency and conformity
with legal and ethical principles.
Moreover, the deaccessioning of an object should be undertaken with a fullunderstanding of its significance, its character, and any loss of public trust that might
result from such action7.
The museum’s collections policy should define how the process of deaccessioning
will be carried out and delineate the positions of the stakeholders that should beinvolved (governing body, director, curator, etc.)8.
Disposition
Once an object has been deaccessioned from a museum’s collection, it is still theproperty of the museum until ownership of the object is transferred legally and theobject leaves the custody of the museum that has deaccessioned the object.
After an object has been deaccessioned, the museum must determine the means for
disposing of the object (e.g. donation to another cultural or educational institution,transfer, exchange, sale, auction or if more appropriate by private sale, return orrestitution to its rightful private owner or the country of origin). If none of the above ispossible, disposition might also include the destruction of the object.
After having made the decision to de-accession, there is a strong presumption that adeaccessioned object should first be offered to another museum or public collecting
institution9 except in cases where the object is fraudulent or where it’s provenance issuspect.
Funds realized from the deaccessioning and disposal of an object should be usedsolely for the benefit of the museum’s collection, that is, acquisitions to and care for7

that same museum’s collection10. By no means, however, should the funds be used
for the costs of regular museum administration or maintenance.
The process of deciding whether to deaccession an object should be distinct from thedetermination of the means for its disposition as well as the process for deciding how
the proceeds from its disposition should be used for the museum’s collection. A
museum’s collections policy should state what methods of disposition are acceptable
and should have established guidelines for the disposition of different kinds orcategories of objects11.
The process of deaccessioning and disposing of an object should be carefully
documented in the museum’s collections records, and these records should becomea permanent part of the museum’s records, maintained even after an object isdisposed from a museum’s collection12.
Museum personnel, the governing body, or their family members or close associates,
should not be permitted to purchase an object that has been deaccessioned from acollection for which they are responsible13.
Whenever possible, it is good practice for museums to promote transparency in its
acquisitions, accessioning, deaccessioning, and disposition procedures.
