are faced with more complex considerations. While a close friend or family member may be suitable for managing personal affairs in times of incapacity, businesses may require subject matter experts and depending on the business structure, there are certain governance requirements. Therefore, the Business Lasting Power of Attorney (BLPA) is a separate arrangement that is similar in function to the LPA. Business owners arranging a LPA and BLPA can therefore split between personal and business affairs. Administrative and legal background The LPA system is administered by the Office of the Public Guardian (OPG), an agency of the Ministry of Justice of the United Kingdom. Its contact details are explained in section 2.2 below headed 'The role of the OPG in relation to Lasting Powers of Attorney'. The OPG was set up in 2007 under the MCA 2005, replacing the similarly-named Public Guardianship Office which had a more limited range of responsibilities. It is headed by the Public Guardian, whose main role is the protection of people who lack mental capacity. The MCA 2005 provides a statutory framework to empower and protect vulnerable people who are not able to make their own decisions. It makes clear who can take decisions on their behalf, in which situations, and how they should do so. Through the LPA, the Act enables people to plan ahead for a time when they may lose capacity. Detailed guidance is provided by a Code of Practice to the MCA 2005 to the Act, which people working as professionals in this field are required to 'have regard to': that is, to observe, unless (having decided in specific circumstances not to do so) they are prepared to explain afterwards – most probably in a post-incident inquiry – why not. Where there are suspicions that an attorney might not be acting in the best interests of the donor, the OPG will arrange an investigation. If the OPG decides that formal action is required, and more generally if any disputes arise on subjects covered by the MCA, the matter is referred to the Court of Protection (CoP), which is part of the Family Division of the High Court and was set up under the MCA for this purpose. The role of the CoP in decision-making is complementary to that of the OPG in relation to matters of regulation and supervision. The 'five principles' The guiding principles of the MCA 2005 are set
