A partnership agreement and a shareholders’ agreement serve similar purposes in governing the relationships and responsibilities among members of a business, but they apply to different structures. A partnership agreement is specific to partnerships, outlining the terms of collaboration, profit sharing, roles, and responsibilities among partners, typically in a business owned directly by individuals. In contrast, a shareholders’ agreement is used in companies and governs the rights and obligations of shareholders, including issues like share transfers, voting rights, and corporate governance. Essentially, the former focuses on interpersonal relationships and business operations among partners, while the latter addresses the rights and duties of individuals who own shares in a company.
