The document discusses the importance of using plain language in legal writing to ensure proper notice and understanding. It notes that notice requires both gaining attention and comprehension of the legal effects and consequences. The science of cognitive neuroscience and linguistics shows that true understanding requires using familiar words and expected information presented clearly without jargon, surprises or ambiguity. Recent court cases have found that merely making a notice noticeable is not sufficient to demonstrate legal notice and comprehension, especially if the notice contains complex language or is visually confusing. The duty to communicate clearly means using a quality standard of comprehensibility so that people can understand how to exercise their legal rights.
