When does a partnership formally begin its legal existence?

A partnership formally begins its legal existence typically upon registering with the appropriate state authority, which in many jurisdictions includes filing with the Securities and Exchange Commission (SEC) or a similar entity. This registration process usually involves submitting formal documents such as a certificate of partnership, which is essential for establishing the partnership's legal status and allowing it to operate within the regulatory framework.

While other elements, such as signing a partnership agreement or the partners' decision to operate together, are important for establishing the partnership's internal relationships and operations, they do not confer legal status on the partnership. The legal existence is recognized when the necessary documentation is filed with the appropriate authority, thus providing the partnership with the rights and responsibilities under the law.
