When someone initiates legal action against another person or entity, they are said to "go to law." However, this phrase can be substituted with a variety of synonyms to convey the same meaning. One alternative is "sues," which specifically refers to initiating a lawsuit. "Litigates" is another term used to describe the act of taking legal action. "Pursues legal action" is a more general phrase that can be used in place of "goes to law." Additionally, "takes legal recourse" or "seeks legal remedy" can be used to describe someone beginning legal proceedings. All of these synonyms convey the same idea of someone seeking legal resolution to a dispute.
