Ken has established an international reputation as the leading expert on contract language. He is the author of the bestselling A Manual of Style for Contract Drafting, published by the American Bar Association and now in its fifth edition. Ken offers public and in-house Drafting Clearer Contracts training globally. His work has often been cited by courts, including the U.S. Supreme Court and the Delaware Court of Chancery.
