Artikel 13

The States Parties to this Convention also undertake, consistent with the laws of each State:
(a) To prevent by all appropriate means transfers of ownership of cultural property likely to promote the illicit import or export of such property;
(b) to ensure that their competent services co-operate in facilitating the earliest possible restitution of illicitly exported cultural property to its rightful owner;
(c) to admit actions for recovery of lost or stolen items of cultural property brought by or on behalf of the rightful owners;
(d) to recognize the indefeasible right of each State Party to this Convention to classify and declare certain cultural property as inalienable which should therefore ipso facto not be exported, and to facilitate recovery of such property by the State concerned in cases where it has been exported.
