Some countries outlaw the act of engaging in sexual activity in exchange for money, while others allow prostitution itself, but prohibit most forms of procuring (such as operating brothels, facilitating the prostitution of another, deriving financial gain from the prostitution of another, soliciting/loitering, etc.) in an attempt to make it more difficult to engage in prostitution.

Depending on the country, various prostitution related activities may be prohibited (where a specific law forbids such activity), decriminalized (where there is no specific law either forbidding or allowing and regulating the activity), or regulated (where a specific law explicitly allows and regulates the activity if certain conditions are met). Activities which are subject to the prostitution laws include: selling and buying sexual services, soliciting in public places, running brothels, deriving financial gain from the prostitution of another, offering premises to be used for prostitution etc. Often the prostitution laws are not clear cut and are subject to interpretation, leading to many legal grey areas.
