Power of Attorney for Parent with Dementia in BC
The Window Is Narrower Than You Think
A dementia diagnosis does not automatically mean your parent can no longer sign legal documents in British Columbia. Capacity under BC law is task-specific and time-specific — it depends on the document being signed and the parent's cognitive state at the moment of signing. A parent with early to moderate dementia may still have capacity for some documents but not others.
The problem is that this window shrinks progressively and unpredictably. A parent who can express preferences today may not be able to next month. Families who wait for "the right time" frequently discover there is no right time left.
What an EPOA Requires — and Why Dementia Often Disqualifies
An Enduring Power of Attorney has the highest capacity bar of any planning document in BC. Under Section 12 of the Power of Attorney Act, the parent must understand the nature and approximate value of their property, their obligations to dependants, the fact that the attorney could misuse authority, the risk of estate devaluation, the scope of authority being granted, and the right to revoke.
For a parent with moderate to advanced dementia, meeting this six-part test is often impossible. If the parent cannot articulate what they own or who depends on them financially, the EPOA is not safely executable. A notary or lawyer who suspects the parent lacks this level of understanding should refuse to witness the document — and if they proceed anyway, the EPOA is vulnerable to a later challenge.
The Section 7 Safety Net
British Columbia designed the Section 7 Representation Agreement specifically for this situation. Under Section 8 of the Representation Agreement Act, the capacity threshold is deliberately lower. The adult can execute an RA7 even if they cannot independently manage their own affairs or understand the full legal consequences of the document.
The capacity assessment considers whether the adult expresses a desire for a representative, demonstrates choices and preferences, understands that the representative may make decisions affecting them, and has a relationship of trust with the proposed representative. A parent who recognizes their daughter, can nod or shake their head to indicate choices, and shows comfort in their daughter's presence may meet this standard — even if they could not explain what a power of attorney is.
An RA7 grants the representative authority over routine financial management (paying bills, managing pensions, filing taxes), minor and major healthcare consent (excluding end-of-life decisions), and personal care decisions. It cannot authorize real estate transactions or the refusal of life-sustaining treatment.
If an RA7 includes routine financial management, the Act requires the appointment of a monitor unless the representative is the adult's spouse, a trust company, a credit union, or the PGT, or two or more representatives are required to act unanimously on all authority under that provision.

After a Stroke: Timing Matters
Stroke survivors often present a specific challenge. Capacity may fluctuate dramatically in the days and weeks following a stroke — lucid one morning, confused the next. BC law evaluates capacity at the moment of signing, which means the document should be executed during a lucid period, ideally with a physician's assessment confirming capacity contemporaneously.
If your parent is in hospital following a stroke and you are trying to get documents signed, ask the treating physician or hospital social worker to help arrange an assessment for the specific document you need — a Section 7 RA requires different cognitive abilities than an EPOA.
The hospital social worker can often help coordinate this assessment. Every day of delay risks the parent declining further, and once the window closes entirely, the remaining pathways include PGT statutory property guardianship or a committeeship application to the Supreme Court — the latter typically involves $7,500 to $12,500 in costs and takes three to four months.
What You Cannot Do
No matter how clearly the parent expresses a preference, some actions are off the table once capacity is lost:
- An EPOA signed by a parent who lacked capacity may be challenged
- An RA9 (the enhanced version that covers end-of-life decisions) requires full traditional capacity — the inclusive standard only applies to RA7s
- You cannot retroactively create legal authority. The documents must be signed while some capacity exists
If your parent has no remaining capacity at all — cannot express preferences, does not recognize family members, cannot communicate in any form — the RA7 option is foreclosed. The family's choices narrow to statutory property guardianship through the PGT or a court-ordered committeeship.
Acting Now
If your parent has a dementia diagnosis but still recognizes family and can express basic preferences, the time to act is today. Have a lawyer or notary assess whether they can meet the RA7's inclusive capacity standard. If they can, execute the RA7 immediately. If they also meet the higher EPOA threshold, execute that too.
Our British Columbia Power of Attorney & Personal Directive Kit includes capacity threshold checklists for each document type, so you can assess whether the RA7 safety net is still available before booking the notary appointment.
