Law schools do not recommend that you major in any particular field as an undergraduate. But they typically do recommend developing skill in careful reading and especially writing—the precise skills that English majors develop. For example, see the American Bar Association's online guide to Preparing for Law School.
In fact, Justice John Paul Stevens of the U. S. Supreme Court has said that “the best preparation for the study of law [is] the study of poetry, and especially lyric poetry”—the study of literature, in his view, helps students learn to analyze language, to recognize ambiguity, and to develop consistency in interpretation.

The department regularly offers a course in Legal Analysis and Writing.
