How to Get Power of Attorney for Someone With Dementia in Northern Ireland

A Diagnosis Isn't the Same as Incapacity

One of the most common misconceptions families face: a dementia diagnosis does not automatically mean the person lacks the mental capacity to sign an Enduring Power of Attorney. Capacity in Northern Ireland is assessed on a decision-specific, time-specific basis. The question isn't "do they have dementia?" — it's "can they understand what an EPA is, what powers they're granting, and who they're appointing, at the moment they sign?"

Many people in the early and middle stages of Alzheimer's, vascular dementia, or other cognitive conditions can still meet this threshold. They may struggle with complex financial calculations while retaining a clear understanding of who they trust to manage their money.

Getting a Capacity Assessment

If there's any doubt about capacity, arrange a medical assessment before the signing. Ask the donor's GP for a contemporaneous certificate confirming that, in the doctor's professional opinion, the donor understood:

• The nature and effect of the EPA
• The scope of powers being granted
• The identity and role of the attorneys they're appointing

This GP certificate isn't legally required to create a valid EPA, but it's powerful insurance. If a relative later challenges the EPA during registration, the dated medical assessment makes the challenge significantly harder to sustain.

The assessment should happen as close to the signing date as possible — ideally the same week. Dementia is progressive, and a certificate from six months ago carries less weight.

The Window of Opportunity

The critical thing to understand: an EPA must be created before the donor loses capacity. There is no mechanism in Northern Ireland to create a power of attorney retrospectively. Once someone genuinely cannot understand the nature of the document they're signing, the window has closed permanently.

This creates urgency for families who are watching a parent or spouse decline. The question isn't whether to act — it's how quickly. Every month of delay narrows the window.

If the donor has good days and bad days (fluctuating capacity), the EPA can be signed during a period of lucidity. Schedule the signing for the donor's best time of day — many dementia patients are clearest in the morning. Have the GP assessment and signing happen in close succession.

What If It's Already Too Late

If the person has fully lost capacity and never signed an EPA, the family cannot create one. The route to broad authority over their finances is through a Controllership — a High Court order obtained through the Office of Care and Protection in Belfast.

Controllership is expensive (over £2,000 in first-year costs, with ongoing annual fees), slow (typically six months), and restrictive (the controller cannot incur any expense over £500 without a specific court order). It's the exact situation an EPA is designed to prevent.

There is one simpler alternative if the person's only income is state benefits and pensions with no significant property or savings: a Department for Communities (DfC) Appointeeship. This is free to arrange and allows a relative to receive and manage the person's benefits. But it covers nothing beyond state payments — no bank accounts, no private pensions, no property.

What the EPA Can't Do for Healthcare

Even with a valid EPA in place, the attorneys' authority extends only to property and financial affairs. Northern Ireland has no legal mechanism for granting a power of attorney over healthcare decisions. The Mental Capacity Act (Northern Ireland) 2016 was intended to fill this gap, but the relevant sections remain uncommenced.

For healthcare planning alongside dementia, families should consider:

• An Advance Decision to Refuse Treatment (ADRT) — a document specifying treatments the person wants to refuse if they lose capacity
• An Advance Statement — a broader expression of wishes about care preferences

Neither carries the same legal weight as an English Health and Welfare LPA, but they give clinicians documented guidance on the person's wishes.

The Northern Ireland EPA Guide covers the full process — from capacity assessment through signing and registration — with specific guidance for families navigating dementia.
