Business partnerships operating in a county, especially partnerships set up for real estate deals, often will file partnership papers with a county recorder's office.
The partnership documents will list the general partners and the shares held by each of the partners.
The limited partners are only listed in rare instances. Limited partners are essentially only passive investors and are not playing an active role in the company.
The partnership papers at the recorder's office are only indexed by names of the partnerships, not by the names of the individual general partners or limited partners.
