Уголовный кодекс Российской Федерации
Factual polygamy and sexual relationships with several adult partners are not punishable in accordance with current revisions of Criminal Code of Russia and Code of the Russian Federation on Administrative Offenses. But multiple marriage can't be registered and officially recognised by Russian authorities because Family Code of Russia (section 14 and others) prohibits registration of marriage if one of person is in another registered marriage in Russia or another country. Polygamy is tolerated in predominantly Muslim republics such as Chechnya, Ingushetia, and Dagestan.
