What is the Difference Between a Deputyship and a Lasting Power of Attorney?

When it comes to managing the affairs of someone who lacks mental capacity, understanding the difference between a Deputyship and a Lasting Power of Attorney (LPA) is crucial. Both provide legal authority to make decisions on behalf of another person, but they serve different purposes and are used in different circumstances.

This post breaks down the key differences, helping you decide which option is appropriate for your situation.

What is a Deputyship?

A Deputyship is a legal appointment made by the Court of Protection when an individual lacks the capacity to make decisions and has not created an LPA. A deputy is authorised to make decisions on behalf of the person, and their responsibilities are closely monitored by the Office of the Public Guardian.

  • When is it Used?
    Deputyship is required if someone becomes unable to make decisions and has not previously set up an LPA.
  • Types of Deputyship:
  • Property and Financial Affairs Deputyship: Covers managing finances, paying bills, or selling property.
  • Health and Welfare Deputyship: Relates to decisions about medical care and living arrangements (granted in rare cases).
  • How is it Arranged?
    A Mental Capacity Assessment is needed to confirm the person’s lack of capacity, followed by an application to the Court of Protection.

What is a Lasting Power of Attorney (LPA)?

An LPA is a legal document created by an individual while they still have capacity, appointing someone they trust to make decisions on their behalf if they lose capacity in the future.

  • When is it Used?
    An LPA is used when someone anticipates needing help managing their affairs and proactively sets up this arrangement.
  • Types of LPA:
  • Property and Financial Affairs LPA: Authorises decisions about money, property, and financial matters.
  • Health and Welfare LPA: Covers decisions about healthcare, daily routines, and living arrangements.
  • How is it Arranged?
    The individual completes the required forms and registers them with the Office of the Public Guardian while they have capacity. A certificate provider confirms they understand the arrangement.

Which Option is Right for You?

  • Choose an LPA if…
    You are planning for the future and want to appoint someone you trust to make decisions on your behalf.
  • Choose Deputyship if…
    You need to make decisions for someone who has already lost capacity and hasn’t set up an LPA.

How to Navigate the Process

Whether you’re setting up an LPA or applying for Deputyship, it’s essential to understand the legal and practical implications of each. Here are some tips:

  • Seek Professional Advice: Speak to a legal or social work professional to ensure you’re choosing the right option.
  • Understand the Responsibilities: Both deputies and attorneys must act in the best interests of the individual they represent.
  • Prepare Thoroughly: Ensure all forms and evidence are complete to avoid delays.
