Belgium
The protection of cultural property is federally regulated by the law on the restitution of cultural property unlawfully removed from the territory of a foreign state (Loi relative à la restitution de biens culturels ayant quitté illicitement le territoire de certains Etats étrangers, Dossier numéro 1996-10-28/54).
The law of 28.10.1996 was last amended by the law of 23.5.2016 (Dossier numéro 2016-05-04/09).
Beside it stands a decree specific to the Wallonia-Brussels Federation on movable cultural property and the intangible heritage of the French Community of 11 July 2002 (Décret relatif aux biens culturels mobiliers et au patrimoine immatériel de la Communauté française)
EU regulations
The licence for the export of cultural goods from the European customs territory is subject to Council Regulation (EC) No. 116/2009 of 18 December 2008 on the export of cultural goods (OJ L 39, 10.2.2009, p. 1). Exports to the internal market, however, are subject to national regulations, which may differ
from the Council regulation with respect to the value and age thresholds of the categories of the protected cultural property (Overview of this).
Further information on the legal situation can be requested from the EUR-Lex Datenbank. The EU also maintains a special database for the regulations regarding the protection of cultural property. The multilingual UNESCO Database of National Cultural Heritage Laws provides access to the relevant national legal bases. A brochure on the functionality of this database can be found here. Another source of information on national cultural asset protection laws is the Sharing Electronic Resources and Laws On Crime (SHERLOC) of the United Nations Office on Drugs
and Crime (UNODC).
