But these non-economic rights are not considered part of the membership interest. Furthermore, the noneconomic rights are not freely transferable by the member. The lack of free transferability of noneconomic LLC member rights is one of the features that enable LLCs to attain partnership tax status. Adding new members The LLC may increase its membership by adding members. There are basically three ways to provide for the admission of new members, depending on which state's statute is involved.
Some states allow LLCs to add new members if the articles of organization so provide.
Other states allow LLCs to add new members upon their compliance with the operating agreement or, if the operating agreement is silent on additional members, upon the consent of the members. The third category contains states with LLC laws that do not address the terms under which additional members may be added. In these states, it is likely that additional members may be added upon the unanimous consent of the members. Sometimes members of an LLC do not want additional members to be added. For example, a closely held LLC with three members may not want to run the risk that two of the members would agree to additional members over the objection of the third member.
