What is Insurance Regulatory Law?

Legal Definition
Insurance regulatory law is the body of statutory law, administrative regulations and jurisprudence that governs and regulates the insurance industry and those engaged in the business of insurance. Insurance regulatory law is primarily enforced through regulations, rules and directives by state insurance departments as authorized and directed by statutory law enacted by the state legislatures. However, federal law, court decisions and administrative adjudications also play an important role.
