Passive income: NO

Starting an AI Legal Expense Auditing Service can potentially lead to earning passive income once the necessary systems and automation are in place. However, achieving true passivity in this hustle may not be common and could require a significant amount of initial setup and ongoing maintenance. Setting up robust automation tools, AI algorithms, and outsourcing certain tasks are crucial for reducing manual work and scaling the business efficiently. While some individuals may reach a level of passive income with this side hustle, it may not be the norm, and most likely, it will require ongoing involvement to some extent. It's important to note that myths around the complete passivity of such services may lead to unrealistic expectations. Realistically, passive income in this field may be more achievable for those willing to invest time, resources, and effort into building and maintaining a streamlined operation.
