, I quote;
"In the following countries, incest is legal: Belgium, China, France, Japan, Latvia, Portugal, Russia (marriage prohibited), South Korea, Turkey (marriage prohibited).
Incest is legal for adults only in Argentina, Israel (over 21), Ivory Coast, the Netherlands (marriage prohibited), the Philippines (marriage prohibited), and Spain.
Incest is legal in Brazil if over 14 and in Thailand if over 15; however, most marriages in these countries are disallowed or prohibited. Incest is legal in Italy unless it provokes public scandal."
and about the U.S.;
"In the United States, laws pertaining to incest vary from state to state. All states have laws that make incest illegal but with a wide assortment of exceptions and/or punishments. For example, Rhode Island prohibits incestuous marriages but has no laws against incest in general. New Jersey tolerates incest provided the participants are at least 12 years of age. In other states, including Idaho, Nevada, and Michigan, incest is not only illegal but can also be punished with life in prison.
State laws typically consider incest a statutory crime and classify it as a felony. Rape and incest are considered separate crimes, as incest includes mutual consent while rape does not. That said, if one participant is under the legal age of consent, the act is generally considered statutory rape (rather than incest) because the underaged participant is legally unauthorized to grant consent."
according to this site, incest is legal in a total of 89 countries [data from 2024].
