Renaming for major donors is standard operating procedure among business schools, but law schools have caught on that there is big money in naming rights—a trend experts say will gain momentum in the coming years.

Nearly a quarter of all American Bar Association-accredited law schools are named after someone. Among them, 9% are named for people who cut big checks. Eight law campuses are named for former U.S. Supreme Court justices, while another eight bear the monikers of their founders, former deans, or key university officials.

Here, we've compiled data on the 23 donations that led law schools to rebrand in honor of their patrons. Our list kicks off in the 1960s with the University of Southern California Gould School of Law, but the action really picks up in the 2000s. And although there are some outliers, most of the recent naming donations fall between $20 and $50 million.
