“胜诉”常见的英文表达是 “win a lawsuit” 或 “prevail in a lawsuit” 。
“win a lawsuit”：直接明了地表达了在诉讼中取得胜利，是最常用、最通俗易懂的说法。例如：The company finally won a lawsuit against its competitor.（该公司最终在与竞争对手的诉讼中胜诉。）
“prevail in a lawsuit”： “prevail”有“获胜；占优势”之意， “prevail in a lawsuit” 同样表示在诉讼中获胜，语气稍显正式、书面。例如：Despite facing many difficulties, the plaintiff managed to prevail in the lawsuit.（尽管面临诸多困难，原告还是成功在诉讼中胜诉了。）
