After graduating from Dickinson College, Capehart attended Harvard Law School and completed his law degree in 1934 at Temple University Law School at night during the Great Depression. On October 1, 1930, he clerked for the law firm of French Richards and Bradley, which he later joined. Capehart continued to practice law well into his 90s and came to the office until after his 100th birthday, when he stopped driving. During his eighty years with the firm, the third-oldest firm in New Jersey, it grew from four lawyers to more than 70.
Among other activities, Capehart was a member of the American College of Trial Lawyers, The National Association of Railroad Trial Council, The American Bar Foundation and the American, New Jersey, Burlington County, and Camden County bar associations. His individual practice included litigation, railroad, labor law, worker's compensation, real estate, corporation's estates, and trusts.
