Should You Be Shopping Your Malpractice Insurance? Should You Be Shopping Your Malpractice Insurance? If you have professional liability insurance for your legal practice, you’re off to a great start. But once it’s in place, should you “set it and forget it?” Or do you need to shop the coverage on every renewal? “The rule of thumb I tell my clients is to get a comparative quote every three to five years,” said Joe Barnard, Director of Professional Liability Programs for ProDefender. “Things can change in the insurance market over that period of time, and you may find better pricing or a better fit for the coverage you need.”
