The basics of how to bring or defend a case aren't difficult, but trying to get on top of every nuance of procedure and strategy isn't easy. That's why Nolo suggests a two-pronged approach: learn how to handle routine representation tasks yourself while hiring a lawyer as a self-help law coach to provide advice on strategy and tactics as needed. In many situations, hiring a lawyer to coach your self-help efforts will cost only about 10-20% of what it would cost to hire the lawyer to do the entire job.
Ten years ago, trying to find a lawyer who would help you find your own way through the legal system was next to impossible. Today, given the surplus of lawyers and a gradual change in the profession's attitude towards self-helpers, it's much easier. Because law is an increasingly specialized field, however, you'll want to find someone who is knowledgeable about your type of problem -- not just any lawyer.
