Is a Power of Attorney Valid if the Person Is No Longer Capable?

Understanding the Validity of a Power of Attorney After Incapacity in Quebec

Many people believe that a power of attorney automatically becomes invalid when the person who signed it becomes incapable. Under Quebec law, however, the answer is more nuanced. Whether a power of attorney remains valid after incapacity depends on the type of document, the circumstances, and whether a protection mandate (mandate in anticipation of incapacity) has been homologated or a tutorship has been established.

If you are asking questions such as “Is a power of attorney still valid if the person has dementia?”, “Can a mandatary continue using a power of attorney after incapacity?”, or “What happens to a power of attorney when someone is no longer capable?”, this text further explains the legal rules that apply in Quebec.

What Is a Power of Attorney?

A power of attorney (also called a procuration) is a legal document through which one person (the principal or mandator) authorizes another person (the mandatary or attorney) to perform specific legal or financial acts on their behalf.

A power of attorney may allow the mandatary to:

• Access bank accounts;
• Pay bills;
• Manage investments;
• Sign contracts;
• Deal with government agencies;
• Sell or administer certain property if authorized.

The power granted depends entirely on the wording of the document.

Does Incapacity Automatically Cancel a Power of Attorney?

The answer is not necessarily immediately, but a power of attorney is generally not intended to serve as a permanent substitute once the principal has become incapable.

Under Quebec law, a power of attorney is based on the principal’s consent and ability to supervise the mandatary. When a person becomes incapable of looking after their interests, the legal framework changes significantly.

If the incapacity is serious enough to require legal protection, the situation should normally be addressed through:

• the homologation of a protection mandate (if one exists); or
• the establishment of a tutorship to a person of full age.

Once a protection regime becomes applicable, the ordinary power of attorney generally no longer serves as the appropriate legal authority for managing the incapable person’s affairs.

Can a Mandatary Continue Using a Power of Attorney?

In practice, financial institutions sometimes continue accepting a power of attorney until they become aware of the person’s incapacity or until a court decision changes the legal situation. However, this does not necessarily mean the mandatary has unlimited legal authority.

A mandatary who continues acting after learning that the principal has become incapable should proceed with extreme caution.

Continuing to manage another person’s assets without proper legal authority may expose the mandatary to:

• legal challenges;
• claims for reimbursement;
• personal liability;
• removal from administration;
• allegations of financial exploitation.

Every transaction must be assessed according to the person’s legal capacity and the applicable protective measures.

What If the Person Has Dementia or Alzheimer’s Disease?

A diagnosis of dementia or Alzheimer’s disease does not automatically invalidate a power of attorney.

The decisive question is whether the individual remains legally capable of understanding the nature and consequences of the decisions being made.

Many individuals diagnosed with cognitive impairment continue to possess legal capacity during the early stages of their illness.

As the disease progresses, however, incapacity may eventually require:

• medical and psychosocial assessments;
• homologation of a protection mandate;
• appointment of a tutor.

Each situation must be evaluated individually.

What Happens If There Is No Protection Mandate?

If the person never signed a protection mandate, relatives cannot simply continue relying on an existing power of attorney indefinitely once incapacity arises.

Instead, an application may need to be made to the court for the establishment of a tutorship if the legal criteria are met.

Until proper legal authority exists, important financial and legal decisions may become difficult or impossible.

Can Someone Challenge the Use of a Power of Attorney?

Yes.

If family members believe that a mandatary is improperly using a power of attorney after the principal has become incapable, they may seek legal remedies.

Examples include:

• requesting an accounting;
• asking the court to review transactions;
• seeking the appointment of a tutor;
• contesting unauthorized transactions;
• alleging financial abuse or exploitation of a vulnerable person.

Courts carefully examine whether the mandatary acted in the principal’s best interests and within the limits of the authority granted.

What If the Power of Attorney Was Signed After the Person Had Already Become Incapable?

This raises a different legal issue.

A power of attorney is only valid if the person had legal capacity at the time it was signed.

If the principal was already incapable of understanding the nature and consequences of granting a power of attorney, the document may be declared invalid.

Evidence often considered includes:

• medical records;
• physicians’ assessments;
• neuropsychological evaluations;
• witness testimony;
• the notary’s or lawyer’s observations;
• surrounding circumstances.

Each case depends on its own facts.

How Can You Protect an Incapable Relative?

If you suspect that someone is using a power of attorney improperly after a person has become incapable, it is important to seek legal advice promptly.

Early intervention can help:

• protect the incapable person’s assets;
• prevent financial abuse;
• preserve evidence;
• obtain court orders where necessary;
• establish the appropriate legal protection regime.

Prompt legal action often prevents more serious financial losses.
