‘Designated members’ have a number of administrative obligations similar to those imposed on directors of a company, such as appointing an auditor, signing and delivering accounts and annual returns and notifying Companies House of any changes in the structure of the LLP. An LLP can have an unlimited number of members. It must have at least two formally appointed members on incorporation; but will not cease to exist if, for example, one of those members dies. However, if a single member carries on business for more than 6 months, that single member will be personally liable for the LLP’s debts and liabilities.
