LEGAL WRITING
Writing a legal document needn't be a difficult or overwhelming experience. Many legal documents - for instance living trusts, power of attorney documents, wills, and divorce documents - can at least be partially written before bringing in a lawyer, and this can save significantly on some legal expenses. In fact, while there are some special tips to keep in mind for legal writing, the same fundamentals rules for clarity and consistency apply as in all other fields of writing. You must organize your ideas coherently, write your text with a logical flow, and have good editing skills.
