A BOP policy or a business owners policy, is the single most important coverage for a small business. A law firm is no different. After your malpractice insurance, which is your most important coverage, the next thing to consider is a BOP policy. Like a commercial general liability policy, a BOP provides those important coverages usually required by an additional insured. But it also adds property coverage - your business personal property, and if you own your building then the building as well. The third coverage that’s found on a BOP policy is business interruption coverage.
