What type of partner is not known to the public and has no involvement in management?

The type of partner that is not known to the public and has no involvement in management is referred to as a dormant or sleeping partner. This partner contributes capital to the business and shares in the profits but does not actively participate in its management or operations. The term "dormant" emphasizes that this partner is essentially inactive and keeps a low profile, further distinguishing their role from others who may be more involved in decision-making processes.

In contrast, an active partner is typically involved in managing the business and has a visible role in its operations, while a general partner also takes on management responsibilities and has unlimited liability in the partnership. A silent partner, while not involved in management, may still be known to the public, as their status can vary based on the nature of the business. The key characteristic that defines a dormant or sleeping partner is their lack of public identity and managerial engagement, making them a distinct class within partnerships.
