Key takeaways
  • An attorney under an enduring power of attorney has no power to make or change the donor's will.
  • A court-appointed guardian or trustee also cannot make a will for an adult they represent.
  • If you are worried about an attorney, a court application for accounts or termination is the route the Act provides.

Many families worry when one person is given an enduring power of attorney. A common fear is that the person will quietly rewrite a parent's will, or steer the estate in their own favour.

The short answer is that the document does not reach that far. This article explains where an attorney's authority stops, what it does cover, and what you can do if you are concerned.

This article covers the law of Alberta.

What an attorney can do

An enduring power of attorney (EPA) is a document under the Powers of Attorney Act that lets an adult give another person authority over financial decisions. Subject to the Act and the terms of the EPA, the attorney can do anything on the donor's behalf that the donor may lawfully do by an attorney. In this context, the word attorney means the person appointed, not a lawyer.

An EPA is not ended by the donor's later mental incapacity, which is what separates it from an ordinary power of attorney. That is why it matters so much who is named.

Why an attorney cannot change a will

The attorney's power under section 7 of the Act does not include making or changing the donor's will. Under the Wills and Succession Act, an adult can make, alter or revoke a will only if they have the mental capacity to do so, and the will must be signed by the testator.

There is a narrow exception for signing only. Another person may sign a will at a capable testator's direction and in their presence, but that is a signing assist, not a substitute decision-maker, and the person who signs cannot also witness.

The same limit applies to court-appointed guardians and trustees. A guardian or trustee has no power to make a will on behalf of the represented adult.

What an attorney can still affect

Even though the will itself is out of reach, an attorney manages the donor's property during the donor's life. That can change what is left to pass through the estate, which is why families worry.

Concerns about misuse

The Court may order an attorney to bring in and pass accounts for any or all transactions. The donor, the donor's personal representative or a trustee may apply, and if the donor cannot make reasonable judgments about their estate, any interested person may apply. This right applies despite any agreement to the contrary.

Any interested person may also ask the Court of King's Bench to terminate an EPA if that would be in the donor's best interests. The Court cannot appoint a substitute attorney, but may direct the applicant to seek a trusteeship order or appoint an interim trustee.

The Office of the Public Guardian and Trustee cannot investigate complaints against an attorney. If property was fraudulently sold or converted, the Criminal Code treats a person entrusted with a power of attorney as committing theft.

What to do next

Frequently asked questions

Can an attorney rewrite my parent's will if my parent loses capacity?

No. The attorney's authority does not include making or changing the donor's will. A person who lacks the mental capacity to make a will cannot alter one.

Does the EPA still apply after my parent dies?

No. An EPA ends on the donor's death. Authority then passes to the personal representative, such as the executor named in the will, and the former attorney is not automatically that person.

Can the donor take the power away?

Yes, while the donor is mentally capable, they can revoke an EPA in writing unless it is irrevocable. If they are no longer capable, termination needs a court order or a trusteeship order.

Can I make the attorney show what they did with the money?

You may be able to ask the Court for an accounting order under the Powers of Attorney Act, depending on who you are. Alberta.ca advises contacting a lawyer to do this.
