In a significant legal shift, New York has officially repealed a 1907 law that criminalized adultery, making cheating on a spouse no longer a crime after 117 years. This change means that individuals in New York can engage in extramarital affairs without the concern of prosecution or jail time. While adultery is still illegal in 16 other states, the repeal marks a notable move toward more lenient perspectives on marital infidelity in New York.
