Dementia and Power of Attorney: What You Must Know

Dementia and LPA: Why Acting Early Matters

Dementia is the leading cause of death in England and Wales. It affects 1 in 14 people over 65 and 1 in 6 over 80. If you or a family member are concerned about dementia, creating a Lasting Power of Attorney should be a priority.

The Critical Timing Issue

Here's the essential fact about LPAs and dementia:

You can only create an LPA while you have mental capacity to do so.

Once dementia has progressed to the point where you cannot understand what an LPA is and what it does, you cannot create one. No exceptions.

This means:

  • If you're worried about dementia, create LPAs NOW
  • If a parent has early-stage dementia, act IMMEDIATELY
  • Every day of delay increases the risk

Creating an LPA After a Dementia Diagnosis

A dementia diagnosis doesn't automatically mean you lack capacity to create an LPA. In early stages, many people can still:

  • Understand what an LPA is
  • Choose who they want as attorneys
  • Make decisions about their future care

Steps to Take After Diagnosis

  • Don't delay - Capacity can decline unpredictably
  • Get medical input - A doctor's opinion supports validity
  • Choose a suitable certificate provider - Often a GP or solicitor
  • Create both types of LPA - Complete protection
  • Register immediately - Don't wait
  • Capacity Assessment for LPA

    The person creating the LPA must understand:

    • What an LPA is and what it does
    • That they're giving authority to their attorneys
    • That attorneys must act in their best interests
    • That the LPA can be cancelled while they have capacity
    If there's any doubt, a formal capacity assessment from a doctor provides evidence the LPA was validly made.

    What Happens Without an LPA

    When someone with dementia loses capacity without an LPA:

    For Finances

    • Bank accounts may be frozen
    • Bills cannot be paid
    • Property cannot be sold
    • Pensions may become inaccessible
    • Investments cannot be managed

    For Healthcare

    • Family has no legal decision-making power
    • Healthcare professionals make treatment decisions
    • Care home choices may be limited
    • End-of-life wishes may be unknown

    The Only Alternative: Court of Protection

    Without an LPA, the family must apply for a Deputyship order:

    • Takes 4-12 months (or longer)
    • Costs £2,000-5,000+ in fees
    • Requires ongoing annual supervision
    • Annual fees continue indefinitely
    • Much more restrictive than LPA
    All while your loved one needs help they can't get.

    Planning Ahead: Before Diagnosis

    The best time to create an LPA is before any concern arises. Consider creating LPAs if:

    • You're over 50 (or even younger)
    • You have family history of dementia
    • You want peace of mind
    • You have assets to protect
    • You care about healthcare decisions

    If Your Parent Has Dementia

    Adult children often face the difficult task of helping parents who didn't plan ahead.

    If They Still Have Capacity (Early Stages)

    • Have gentle conversations about LPAs
    • Explain you want to help them, not control them
    • Involve their GP if helpful
    • Use a service that makes the process easy
    • Act quickly but sensitively

    If They Lack Capacity

    • Court of Protection is the only option
    • Consider emergency applications if urgent
    • Get legal advice
    • Apply for Deputyship
    • Document all attempts to help

    What LPAs Cover for Dementia Care

    Property and Financial Affairs LPA

    • Accessing accounts to pay for care
    • Managing pensions and benefits
    • Selling property if needed
    • Handling day-to-day finances
    • Managing investments

    Health and Welfare LPA

    • Choosing care homes
    • Making medical decisions
    • Arranging daily care
    • Life-sustaining treatment decisions
    • Where they want to live

    Including Your Wishes

    Your LPA can include preferences specific to dementia care:

    • "I want to stay at home as long as safely possible"
    • "I prefer X care home near my family"
    • "Quality of life matters more to me than length of life"
    • "I want my pet to stay with me if possible"
    • "I wish to continue attending church/synagogue/mosque"

    Choosing Attorneys for Dementia Planning

    Consider:

    • Will they be available for potentially years of care?
    • Can they handle difficult healthcare decisions?
    • Do they understand your values?
    • Can they manage complex finances if needed?
    • Are they good at advocating with care providers?
