An Executor's Duty of Impartiality Between Beneficiaries in Ontario

Being named executor of a family member's estate rarely comes with a clean slate. Executors are often closer to some beneficiaries than others — a sibling they talk to every week, a niece they barely know, an estranged parent. Ontario law does not care about any of that. An executor's duty of impartial treatment of beneficiaries applies regardless of how the executor personally feels about the people involved.

This can be one of the hardest parts of the role, precisely because it asks someone to set aside personal relationships and family history in favour of a strict, evenhanded standard.

What the Duty of Impartiality Actually Requires

An estate trustee is a fiduciary, which means they must act in the best interests of the estate and all its beneficiaries — not just the ones they like, trust, or feel closest to. Impartiality does not mean every beneficiary receives identical treatment regardless of the will; it means the executor applies the will's terms, and their own judgment as trustee, the same way to everyone, without letting personal feelings tip the scale.

Where Bias Tends to Creep In

The executor is also a beneficiary

It is common — and legally permitted — for an executor to also be a beneficiary. The risk is that decisions about timing, expenses, or asset valuation start to (even unconsciously) favour the executor's own share over other beneficiaries' shares.

One beneficiary is more vocal than the others

An executor fielding constant calls from one anxious or demanding beneficiary can end up prioritizing that person's requests — faster updates, quicker distributions — over quieter beneficiaries who are equally entitled to the same attention.

Old family dynamics resurface

Long-standing sibling rivalries, a favoured child, or resentment toward an estranged relative can all quietly shape how an executor exercises discretion, even when the executor believes they are being fair.

Blended families add complexity

Where a will divides an estate between a current spouse and children from an earlier relationship, an executor connected more closely to one side of the family needs to be especially deliberate about even treatment.

What Impartial Administration Looks Like in Practice

• [ ] Send the same updates, at the same time, to every beneficiary — not just the ones who ask
• [ ] Apply the same standard when deciding what counts as a reasonable estate expense, regardless of who benefits
• [ ] Rely on professional valuations rather than personal opinion when an asset's worth affects how shares are divided
• [ ] Treat requests to speed up or delay a distribution the same way no matter which beneficiary is asking
• [ ] Document the reasoning behind discretionary decisions so they can be explained later if questioned

When Partiality Becomes a Legal Problem

Occasional missteps born from stress or inexperience are different from a pattern of favouritism that actually disadvantages a beneficiary. If an executor's bias results in unequal information, delayed or reduced distributions, or decisions that clearly serve one beneficiary's interest over another's, beneficiaries can raise the issue directly, through a passing of accounts, or by asking the court to intervene — which can include removing the estate trustee in serious cases.

Being a Beneficiary Yourself Doesn't Disqualify You

Ontario law does not require an executor to give up their own inheritance or step aside simply because they are also named as a beneficiary. What it requires is extra discipline: separating "what is fair for the estate" from "what benefits me," and being able to show, if asked, that every beneficiary was treated the same way.

How This Duty Interacts With Other Executor Obligations

Impartiality does not stand alone — it works alongside an executor's separate duties to communicate honestly with beneficiaries and to keep proper accounts. An executor who behaves impartially but keeps everyone in the dark is still falling short, because unequal information often looks and feels like favouritism even when none was intended.

A few habits help executors stay on the right side of both duties at once:

• Send the same summary update to every beneficiary at the same time, rather than answering individual questions ad hoc
• Keep a simple written log of major decisions and why they were made
• When in doubt about whether something needs to be shared, share it

None of this requires polished communication skills — it requires consistency, which beneficiaries can usually recognize even when they disagree with a particular decision.
