Capacity Assessment in New Brunswick: When the Window Closes for Advance Directives

The single most consequential moment in advance care planning isn't signing the documents — it's the capacity assessment that determines whether signing is still possible. In New Brunswick, once two healthcare professionals formally document that a person lacks the mental capacity to understand and appreciate their decisions, the ability to create or modify an Enduring Power of Attorney for Personal Care or a Health Care Directive is gone. Everything that follows — court applications, representative appointments, legal fees — flows from that one clinical finding.

How Capacity Is Defined Under New Brunswick Law

Under the Enduring Powers of Attorney Act, an adult is presumed capable unless demonstrated otherwise. That presumption matters: no one has to prove they have capacity before signing an EPA or Health Care Directive. The burden runs the other direction — someone must demonstrate they lack it.

The legal threshold for executing a Personal Care EPA requires that the person understands the personal care decisions involved and appreciates the reasonably foreseeable consequences of making (or not making) the document. This is not the same as understanding every legal nuance. A person with early-stage dementia who can articulate "I want my daughter to make medical decisions if I can't" and grasps what that means in practice likely meets the threshold, even if they struggle with complex financial reasoning.

Capacity is also decision-specific and can fluctuate. A person might lack the capacity to manage their investment portfolio (triggering the need for a Property EPA, which requires a lawyer's certification) while retaining enough understanding to execute a Personal Care EPA with two independent witnesses and a Health Care Directive with one adult witness. New Brunswick law recognizes this distinction explicitly by maintaining separate execution pathways for financial and personal care documents.

Who Conducts the Assessment

When a medical crisis raises questions about a person's ability to participate in their own care, the activation of an existing EPA requires a formal capacity finding by two healthcare professionals — at least one of whom must be a physician or nurse practitioner. Both must assess and document in writing that the individual lacks the capacity to make the specific decisions at issue.

One of these professionals must attempt to inform the individual of the finding, if possible. Only after this documented assessment is signed does the attorney's legal authority under the EPA activate.

For SDMRA court applications (when no EPA exists), the process is more structured. The applicant must submit a Capacity Assessment Report — Form 71.1 — completed by a registered physician, nurse practitioner, or psychologist. This report goes before the Court of King's Bench along with the formal application package.

There is no centralized "capacity assessment service" in New Brunswick. Assessments are conducted by the person's existing healthcare providers, typically their family physician or a specialist (geriatrician, psychiatrist, neuropsychologist) already involved in their care. Wait times for specialist assessments can stretch weeks or months in the province, which is why families facing a parent's visible decline should be moving on advance care documents before the question of capacity becomes a clinical emergency.

The Gap Between "Declining" and "Incapable"

This is where families most often miscalculate. A parent who forgets appointments, repeats stories, or needs help with banking is not necessarily incapable of signing an advance directive. The legal threshold is functional — can the person understand what an EPA does and appreciate the consequences? — not diagnostic. A dementia diagnosis alone does not equal incapacity.

But the trajectory of cognitive decline is predictable in one direction. The practical window for document execution sits in that gap between noticeable decline and formal incapacity — and it narrows faster than most families expect. Individual variation is substantial, so families should not treat a diagnosis as a fixed timetable for the loss of capacity.

Families who recognize the decline but delay because "it doesn't feel urgent yet" often discover urgency only when the hospital requests a capacity assessment during an acute admission — at which point the existing EPA situation is either functional or it isn't, with no room for correction.

What Happens When Capacity Is Lost Without Planning Documents

If a person loses capacity and has no EPA for Personal Care in place, family members have no automatic legal authority over healthcare decisions. The attending medical team will consult the next of kin for informal guidance, but no family member can consent to surgery, refuse treatment, or authorize nursing home placement without legal standing.

The only path forward is a court application under New Brunswick's Supported Decision-Making and Representation Act. The three tiers — Decision-Making Assistant (Tier 1), Decision-Making Supporter (Tier 2), and Representative (Tier 3) — provide graduated authority, but Tiers 2 and 3 require a Court of King's Bench order. The process involves:

• Filing an application with a completed Capacity Assessment Report (Form 71.1)
• Formally serving notice on the adult, their primary caregiver, spouse/partner, and all adult children and siblings
• A mandatory twenty-day objection window during which any served party can contest the application
• A court hearing if objections are filed, or a judge's order if no response is received

The total cost — court filing fees, legal representation, the capacity assessment itself — can be significant. During that time, the person's care decisions remain in limbo, governed by the medical team's best-interest judgment rather than the person's documented wishes.

For individuals with no family or no willing family member, the Public Trustee of New Brunswick (operating under the Legal Aid Services Commission) serves as the representative of last resort, charging statutory fees of $75/hour for administrative duties and $150/hour for legal services, plus a $300 file-opening fee.

Acting Before the Assessment

The practical takeaway is simple and urgent: capacity is a depreciating asset, and the documents that depend on it — the EPA for Personal Care and the Health Care Directive — should be completed while it's unquestionable, not while it's debatable.

The New Brunswick Advance Directive & Living Will Kit walks through both documents with the witnessing rules already built in (two independent witnesses, minimum age 19, no attorneys or their family members), including a capacity self-screening framework that helps families gauge whether the timing is still right — or whether a clinical assessment should be requested before attempting execution.

If you're watching a parent's capacity shift, the question isn't whether you'll need these documents. It's whether they'll still be able to sign them when you finally get around to it.
