Professional Liability Insurance, also known as Professional Indemnity Insurance, provides protection for professional practitioners such as architects, quantity surveyors, home inspectors, lawyers, physicians, and accountants against potential negligence claims from their patients or clients.
The name of Professional Liability Insurance may vary depending on the profession. For instance, in the medical field, it may be referred to as Medical Malpractice Insurance, while Public Notaries may opt for Errors and Omissions Insurance (E&O).

Various professionals, including real estate brokers, appraisers, and website developers, may also benefit from E&O policies. Technology companies, such as software developers and consultants, have specific E&O policies tailored to their needs, focusing on issues like failure to perform, financial loss, and errors or omissions in products or services.
Furthermore, additional coverage options can be included for breach of warranty, intellectual property infringement, personal injury, security breaches, and contract costs, providing comprehensive protection for professionals against a range of potential liabilities.
