Key takeaways
  • An enduring power of attorney takes effect on the latest of signing by both the adult and an attorney, any stated effective date, and confirmation of any named triggering event.
  • It can start right away or only on incapacity, and a document that starts on incapacity must say how and by whom incapacity is confirmed.
  • The attorney must also sign in front of 2 witnesses before acting, and the authority ends when the adult dies.

Many people assume an enduring power of attorney only starts when someone loses capacity. Others assume it starts the moment it is signed. In British Columbia, either can be true, depending on how the document is written.

This article explains when authority begins under the Power of Attorney Act, how a document can be drafted to start right away or later, and what people usually need to show when they rely on it. The details depend on the wording of the document, so get advice on your own.

This article covers the law of British Columbia.

Three things that must all be true

An enduring power of attorney takes effect on the latest of three events:

Because it is the latest of these, a document can start right away or only on incapacity. If nothing in the document delays it, signing by both sides is what starts it.

Starting now or only on incapacity

To be enduring at all, the document must say whether the attorney may act while the adult is still capable or only once the adult is incapable. That choice is the heart of the timing question.

ApproachHow it works
ImmediateThe attorney can act once both have signed, even while the adult is capable
Date-basedThe document states an effective date, and authority starts on the latest of the events
Springing (on incapacity)Authority starts only after the named event, such as incapacity, has been confirmed

If the document takes effect only on an event such as incapacity, the adult must state in it how the event is to be confirmed and by whom, for example by a named doctor's letter. Vague wording here is a common source of delay, so it is worth being specific.

Each approach has trade-offs. An immediate document helps if you want help now, but gives the attorney authority while you are well. A springing document keeps control with you for longer, but someone will have to prove the trigger has happened before anyone can act.

Signing steps before anyone can act

An enduring power of attorney must be in writing, signed and dated by the adult in front of 2 witnesses, and both witnesses must sign in front of the adult. The attorney must also sign in front of 2 witnesses before acting under it. Missing the attorney's signature can leave a document that looks complete but is not yet in effect.

Anyone named as attorney, and that person's spouse, child or parent, cannot witness.

Proving incapacity and when authority ends

If your document starts on incapacity, it must state how the event is to be confirmed and by whom, so the wording of that confirmation step matters. Any person may apply to the BC Supreme Court for an order releasing information needed to decide whether an adult is incapable.

Banks and other institutions may ask for their own steps. Under a 2014 voluntary commitment, federally regulated banks agreed to make information about powers of attorney available to clients. How an institution treats a document can vary, so if one refuses, ask which requirement is unmet. An attorney may also apply to the court for directions.

Authority also stops. An enduring power of attorney terminates when the adult dies. An attorney's own authority ends in several situations, including resignation, bankruptcy, or the attorney's own incapacity or death. An attorney who is the adult's spouse loses authority when the marriage or marriage-like relationship ends, unless the document provides otherwise. If a court declares the adult a patient and appoints a committee, every power of attorney they gave is terminated; if the Public Guardian and Trustee becomes guardian by the statutory or certificate route, the document is suspended and the Public Guardian and Trustee decides whether to terminate it.

What to do next

Frequently asked questions

Can an enduring power of attorney be used while I am still capable?

Yes, if the document says the attorney may act while you are capable. The Act requires the document to state whether the attorney may act while you are capable or only once you are incapable. It can therefore start right away or only on incapacity.

Who decides that I am incapable?

The document itself should say. If it starts only on incapacity, you must state in it how the event is to be confirmed and by whom, for example by a named doctor's letter.

Does the attorney need to sign too?

Yes. The attorney must sign in front of 2 witnesses before acting under the document. The document takes effect on the latest of both signing, any stated date and any confirmed trigger.

What happens if I have no power of attorney and become incapable?

The BC Supreme Court may appoint a committee to make decisions for you. The court may declare a person incapable after reading affidavits from 2 medical practitioners, and notice must be served on the Public Guardian and Trustee at least 10 days beforehand.
