Key takeaways
  • Estate property is held by the executor as trustee for those entitled, not as the executor's own money.
  • Because an interested person can demand accounts, mixed funds are hard to explain without clear records.
  • A judge on a passing of accounts can inquire into the whole administration and order relief for loss.
  • The practical fix is to separate the money, document everything and get advice before moving funds.

Many executors mix money without meaning to. You paid the funeral home or a utility bill from your own account, planning to be repaid. Or an estate cheque arrived and you deposited it where it was convenient. Now you worry that you did something wrong.

Mixing personal and estate funds is called commingling. It is a common problem, and it is usually fixable if you act openly. This article explains why it matters under Ontario law and the steps that generally help.

Why commingling is a problem

Property of a deceased person vests in the personal representative as trustee for the persons beneficially entitled, subject to payment of debts. You hold it for others. Once estate money sits in your personal account, it becomes hard to show which dollars belong to whom.

The risk is practical as much as legal. Personal accounts may be affected by your own debts, your spouse, or your own death. If something goes wrong, beneficiaries may say estate money was lost or used. How the law treats a particular mix of funds depends on the facts, so get advice.

Two common scenarios

What happenedWhy it raises concernUsual first step
You paid an estate bill from your own accountYour money and the estate's are now tangled, though you may be owed repaymentKeep the receipt and invoice, record the payment, and list it for reimbursement
You deposited an estate cheque in your personal accountEstate money is mixed with yoursRecord the deposit and arrange to move the funds into a separate estate account

Paying a legitimate estate expense yourself is generally less worrying than depositing estate money into your own account. Even so, how and when you are reimbursed should be documented. If you are unsure, ask a lawyer before taking money out.

How commingling can come to light

An executor need not account other than by inventory unless requested by or for a person interested in the property or by a creditor. When a beneficiary asks, your bank records become the story of what happened.

If accounts are passed in court, the judge may make full inquiry into and accounting of the whole property of the deceased and its administration. The judge may also inquire into misconduct, neglect or default causing loss to the estate and order damages or other relief. A trustee who wants to pass accounts can also file them in the Superior Court of Justice.

A court may excuse a trustee who acted honestly and reasonably and ought fairly to be excused, but that relief does not apply to a loss arising from investment of trust property. Open records and prompt correction help show honesty, though no outcome can be promised.

How to fix it

If you used a power of attorney before the death

A continuing power of attorney ends when the grantor dies, so the attorney's authority over the grantor's accounts ends at death. An attorney is a fiduciary who must act diligently and keep accounts of all transactions. Records must be kept until, among other events, the person has died and the accounts and records have been delivered to the personal representative. If you were attorney and are now executor, keep the two roles' records separate.

What to do next

Gather the statements and receipts, build a simple ledger and separate the funds. Then speak with an Ontario estates lawyer, especially if amounts are large, beneficiaries are already asking questions, or you are unsure whether to reimburse yourself. Acting openly and early generally puts you in a stronger position than hoping nobody notices.

Frequently asked questions

Is paying an estate bill from my own account commingling?

It mixes your money with the estate's, so it should be documented carefully. Keep the invoice and proof of payment and record it for later accounting. Ask a lawyer before reimbursing yourself.

Can a beneficiary make me explain what I did with the money?

An executor must account other than by inventory if requested by or for a person interested in the property. On a passing of accounts a judge can inquire into the administration.

Can a court order me to pay money back?

On a passing of accounts, a judge may inquire into misconduct, neglect or default causing loss and may order damages or other relief. Whether that applies depends on the facts.

Can I be excused if I acted honestly?

A court may excuse a trustee who acted honestly and reasonably and ought fairly to be excused, but not for a loss arising from investment of trust property. Excuse is for the court to decide.
