Key takeaways
  • An attorney for property owes fiduciary duties, including the core duty to act exclusively for the grantor's benefit.
  • A court may order that all or part of an attorney's accounts be passed, and some people need leave of the court to ask.
  • If the grantor has died and the attorney is also the estate trustee, beneficiaries have been allowed to seek leave for an accounting of the period before death.
  • The Public Guardian and Trustee must investigate allegations that a person is incapable of managing property and that serious harm is occurring or may occur.

A family looks at a parent's bank records and finds large withdrawals, transfers to the person named as attorney, or purchases that make no sense. The attorney says the money was a gift, or for the parent's care. It is a painful and confusing situation.

This article explains the duties an attorney for property owes, the legal routes families use, who can bring a claim, and what evidence tends to matter. Many points depend on the facts and the law in this area is still developing, so a lawyer should review your situation.

What an attorney for property must do

An attorney for property owes fiduciary duties under the Substitute Decisions Act, including the core duty to act exclusively for the grantor's benefit. In plain terms, the money is the parent's, to be used for the parent, not for the attorney.

In one case, on evidence of unexplained ATM withdrawals and personal purchases, a motion judge terminated the power of attorney and appointed the Public Guardian and Trustee as guardian of property. Those findings were not tested on appeal, so treat this as an illustration only.

If your parent is still alive and you fear ongoing harm, the Public Guardian and Trustee route may be the most immediate. If your parent has died, the focus usually shifts to the estate.

Who can bring a claim

At common law, only the grantor or the grantor's estate could call the attorney to account. Where the donor has died and the attorney is also the estate trustee, there can be no true accounting between the two roles, so beneficiaries have been allowed to seek leave under s. 42(4) to obtain an accounting for the pre-death period.

The law on third-party standing to compel an attorney to account is evolving, so do not assume you can or cannot bring a claim without advice. An estate trustee also has a duty to call in the estate's assets. If the estate trustee is not the attorney, they may be the one to pursue recovery.

Evidence and the legal presumptions

The attorney often says that money moved to them was a gift. The law treats gifts and transfers with some suspicion in certain relationships.

Useful records usually include bank and credit card statements, the power of attorney document, any records the attorney kept, medical information about your parent's capacity, and messages about the money. Do not obtain records in ways that break privacy rules; a lawyer can help use proper channels.

A caution about care and compensation

Attorneys sometimes say the money was payment for years of care. A child who provides years of personal care on a promise of a share of property can succeed in unjust enrichment. The claimant must prove enrichment, corresponding deprivation and absence of juristic reason. Such claims turn on their own facts, so an unsupported say-so is rarely the end of the matter either way.

Timing, costs and next steps

The basic limitation period is two years from the day a claim was discovered. Because discovery dates are often argued, do not wait. Estate litigation follows the ordinary civil costs regime, and costs come from the estate only where public policy considerations apply. A blended order, with the loser paying part and the estate bearing the balance, is possible.

Frequently asked questions

Can I make an attorney account for how they spent my parent's money?

A court may on application order that all or part of an attorney's accounts be passed, and a person outside the listed applicants needs leave of the court. Whether you qualify depends on your relationship and the facts.

What if my parent has died?

Where the donor has died and the attorney is also the estate trustee, beneficiaries have been allowed to seek leave to obtain an accounting for the pre-death period. A lawyer can advise on how this applies.

Who investigates suspected abuse?

The Public Guardian and Trustee must investigate allegations that a person is incapable of managing property and that serious harm is occurring or may occur. Its helpline is 1-800-366-0335.

Is a transfer to the attorney automatically a gift?

No. A gratuitous transfer from a parent to an adult child is presumed to be held on resulting trust for the parent, and the child must rebut that presumption. Undue influence presumptions can also apply to gifts.
