One licensed professional should inform another when engaged to review work initially performed by the latter as a professional courtesy and when it is mandated. This protocol fosters transparency and accountability within the professional community. It ensures that the second professional is aware of the review and can provide necessary information or clarification, thereby upholding the professional standards and integrity of the work. It is also typically required by the professional regulatory body to maintain the standards of practice and ensure that all work is up to the required professional standards​​.
