Book excerpt: This report offers an empirical tool to help planners, statisticians, policy makers and advocates understand people's everyday legal problems and experience with the justice system. It sets out a framework for the conceptualisation, implementation and analysis of legal needs surveys and is informed by analysis of a wide range of national surveys conducted over the last 25 years. It provides guidance and recommendations in a modular way, allowing application into different types of surveys. It also outlines opportunities for legal needs-based indicators that strengthen our understanding of access to civil justice.
