Belgium decriminalised prostitution between adults with the sexual criminal law reform of 21 March 2022 (in force 1 June 2022). Selling and buying are legal. Procuring is still an offence, defined narrowly. Advertising for prostitution is banned, except for a sex worker's own ads behind a window in a dedicated venue or on a dedicated medium, and ads on dedicated platforms that meet a royal decree of 18 May 2024 (which, according to the government, may include ads placed by venues). The law of 3 May 2024 lets recognised employers hire sex workers on employment contracts (in force 1 December 2024). It is under challenge at the Constitutional Court, which had not ruled by 22 October 2026. A new Criminal Code in force since 1 September 2026 moves the offences to articles 265 to 272 and lowers the advertising penalty. Municipalities regulate windows, venues and street work.
