The governing document of the LLC is called an operating agreement, and it is within this document that the members lay out all important provisions, such as standards for LLC governance, ownership parameters, and rules around member changes (adding or removing members, or what happens in case of death or incapacity of a member). The operating agreement is an internal document and is an agreement amongst the members or owners, which means it is not recorded with the state.
The articles of organization also should include information about how your LLC will be managed. You need to indicate whether the members of the LLC will do hands-on management or if there will be hired management. Another requirement is to discuss how long the LLC will be in existence (there is no limit on this, so it is fine to say in perpetuity).
If you received a Notice to File a Business Property Statement from the Assessor and your business is no longer in operation, you are still required to file the Business Property Statement. You should also include a note on the Business Property Statement indicating that the business has closed, so the Assessor does not continue to assess the property.
