This chapter considers the requirements needed to become a member of a limited liability partnership (LLP) under the Limited Liability Partnerships Act 2000 (LLP Act). The term ‘member’ of an LLP is used to distinguish them from partners, directors, or shareholders. Since the law applicable to LLPs derives mainly from adaptations from both company law and partnership law, members of an LLP are nevertheless treated as substituting for the role of partner, director, officer, or shareholder depending upon the relevant provision. For the various controls imposed on LLPs and for winding up, members can take the place either of shareholders, directors, or both. The chapter analyses members of an LLP as employees and workers. It then outlines the duties of members of an LLP and to each other as stated in Section 5 of the LLP Act.
