Advisory

Firstly, an advisory opinion is a formal interpretation of the law issued by a court or a high-ranking legal official (like an Attorney General) at the request of a public official or legislative body. Unlike a judgment in a traditional lawsuit, an advisory opinion does not resolve an actual dispute between parties and is typically non-binding. Its purpose is to provide legal guidance on specific questions of law, often concerning the constitutionality of proposed legislation or the legality of contemplated governmental actions. While not directly enforceable, these opinions carry significant legal weight and moral authority, and are often considered by courts as persuasive evidence of the law when similar issues arise in actual litigation. Not all judicial systems permit advisory opinions; for instance, federal courts in the United States generally do not issue them due to the constitutional requirement for a "case or controversy."

Secondly, "advisory law" also encompasses the professional services provided by legal experts to offer guidance and counsel on legal matters. This form of advisory involves lawyers or legal consultants providing clients (individuals, businesses, or government entities) with strategic advice, risk assessment, and compliance guidance. This can cover a vast range of legal areas, including corporate law, regulatory compliance, contract drafting and negotiation, intellectual property, and dispute prevention. Unlike litigation, which focuses on resolving existing conflicts, legal advisory services are proactive, aiming to help clients navigate complex legal landscapes, make informed decisions, and avoid potential legal issues before they escalate. These services are often formalized through advisory agreements or contracts outlining the scope of work and the terms of engagement.
