Prostitution or sex work means offering sex in exchange for money or other advantages.
Prostitution is legal in Belgium if both the sex worker and the client are over 18. They are doing nothing that is forbidden by law. However, it is forbidden by law to have a prostitute work for you, own a brothel or encourage someone into prostitution.
Forced prostitution and human trafficking are forbidden by law. Teenage and child prostitution is also forbidden. “Lover boys” or “pimp boys” who seduce girls, start a fake relationship with them and then force them into prostitution, are also forbidden by law.
