Choosing the right attorneys for a Lasting Power of Attorney (LPA) involves careful thought, especially when multiple family members want to take on the role. This guide helps you understand the process and make informed decisions.

Overview

Understanding LPA attorney options and key considerations for family decision making

When arranging a Lasting Power of Attorney (LPA) for your Mum or Dad, it’s common for more than one family member to want to play a role. You might wonder, "Can my brother and I both be attorneys?" The answer is yes; siblings can act jointly or jointly and severally as attorneys, giving you flexibility in how decisions are made.

Starting the LPA Process

Creating an LPA is a proactive way to ensure that your loved one's wishes are respected if they become unable to make decisions themselves. It's essential to start early because you cannot set up an LPA after mental capacity is lost. The process involves appointing someone you trust to manage financial or health and welfare decisions on their behalf.

Key Questions Before Choosing Your Attorney(s)

Selecting the right attorney involves considering several factors:

  • Do they act in the person's best interests?
  • Are they trustworthy and reliable?
  • Do they understand the person’s values and wishes?
  • Are they willing and able to handle the responsibilities?
  • Will they be available when needed?

These points ensure that the attorney truly advocates for your Mum or Dad, putting their interests first, not their own.

Can Both Brother and Sister Be Attorneys?

Yes. It is common and often advisable to appoint more than one attorney. Brothers and sisters can both be appointed either to act jointly, meaning all must agree and sign every decision, or jointly and severally, allowing them to act independently or together. Most choose jointly and severally for flexibility and continuous decision-making, especially if one attorney is unavailable.

How Many Attorneys Can You Have?

You can appoint one or more attorneys. While one attorney is sufficient, having at least two spreads responsibility and provides backup. You can also name replacement attorneys who step in if the original attorney(s) cannot act.

Important Considerations

Choosing attorneys is a serious legal decision. Attorneys must follow the principles of the Mental Capacity Act 2005, keep finances separate, maintain records, and respect confidentiality. If concerns about attorney conduct arise, the Office of the Public Guardian (OPG) can investigate.
