The Oklahoma Statement of Partnership Authority Form is a legal document used by businesses in the state of Oklahoma to register a partnership. This document is issued by the Oklahoma Secretary of State and outlines the information needed to form a partnership, such as the name and address of the partnership, the type of partnership, and the names and addresses of all partners. There are three types of partnership forms available in Oklahoma: General Partnerships, Limited Partnerships, and Limited Liability Partnerships. The document must be filed with the Secretary of State and is used to prove the existence of the partnership and its members.
