  • The disability benefit scenario deserves particular care.
  • Confirm you haven't already accepted the gift.

Most people assume an inheritance is something you simply accept. In Ontario, it's actually something a beneficiary can legally refuse. Disclaiming an inheritance — formally declining a gift left under a will, or a share arising on intestacy — is a real, if less commonly used, option, and it exists for good reasons.

This article walks through what a disclaimer actually does, why someone might choose it, and what happens to the gift once it's refused.

What Disclaiming Actually Means

A disclaimer is a formal refusal of a gift, made before the beneficiary has accepted any benefit from it. Once you've accepted a gift — even informally, by using or benefiting from the property — you generally can't disclaim it afterward. This is why timing and how you conduct yourself early on matter so much if disclaiming is something you're considering.

Disclaiming is different from simply giving away an inheritance after you've received it. If you accept a gift and then hand it to someone else, that's treated as your own separate transfer of property you already own, which can carry very different legal and tax consequences than a disclaimer made before acceptance.

Common Reasons Beneficiaries Disclaim

ReasonWhy it matters
The gift comes with unwanted obligationsProperty with ongoing costs, maintenance burdens, or liabilities attached can be more trouble than it's worth to the beneficiary
Disability benefit eligibility concernsA beneficiary receiving means-tested government disability benefits may need to avoid receiving assets outright, since an unplanned-for inheritance can affect eligibility
Family or generational planningA beneficiary who is already financially secure may prefer the gift pass to their own children or another family member instead
Avoiding a conflict of interestA beneficiary who is also the estate trustee, or otherwise closely involved in administering the estate, may disclaim to avoid the appearance of self-dealing
Simplifying a complicated estateIn some cases, disclaiming a specific gift can simplify how the rest of the estate is divided among the remaining beneficiaries

The disability benefit scenario deserves particular care. Rather than disclaiming after the fact, families are often better served by planning ahead — for example, through a properly structured discretionary trust designed so the beneficiary has no fixed entitlement the trustee is obligated to pay out, which is a long-established and widely used planning tool for exactly this situation. A disclaimer made too late, after benefits have already been affected, can't always undo that damage.

How a Disclaimer Is Made

  1. Confirm you haven't already accepted the gift. Using estate property, cashing a distribution, or otherwise acting as though you own it can make a later disclaimer ineffective.
  2. Put the disclaimer in writing. A clear, signed document identifying exactly what is being disclaimed avoids ambiguity about what you refused and when.
  3. Deliver it to the estate trustee. The estate trustee needs to know the disclaimer has been made so they can properly redirect the gift.
  4. Get legal and, where appropriate, tax advice before signing. Because a disclaimer changes who receives property — and can have consequences for the person disclaiming and for those who receive the gift instead — it's worth having both angles reviewed before finalizing anything.

What Happens to a Disclaimed Gift

Generally, a disclaimed gift is treated as though the disclaiming beneficiary predeceased the will-maker, and the gift then passes according to the will's own terms for that situation — for example, to an alternate beneficiary named in the will, or, if there is no relevant alternate provision, potentially back into the residue of the estate to be divided among the remaining beneficiaries. On an intestacy, a disclaimed share is redirected according to the intestacy rules as though the disclaiming person had predeceased the deceased. Exactly how this plays out depends heavily on how the specific will (or, on intestacy, the statutory scheme) is worded, which is why reviewing the actual document matters before assuming what will happen.

A Word on Family Arrangements

Sometimes beneficiaries would rather rearrange who gets what by agreement, rather than through a formal disclaimer — for instance, all the adult beneficiaries agreeing to a different split than the will provides. This is possible in some circumstances, but it requires everyone affected to agree, proper documentation, and careful legal advice, since an informal handshake arrangement can create its own complications later, including for tax purposes.

Frequently asked questions

Can I disclaim only part of an inheritance?

In many cases, yes — a partial disclaimer of a specific gift or asset is possible, though the details depend on how the gift is structured in the will. A lawyer can confirm whether a partial disclaimer works for your specific situation.

Do I have to give a reason for disclaiming?

No. A disclaimer generally doesn't require you to justify your reasons to the estate trustee or other beneficiaries — you simply need to make it properly and before accepting any benefit from the gift.

Once I disclaim, can I change my mind?

Generally, no — once a valid disclaimer is made, it's treated as final. This is exactly why getting advice before signing matters, rather than after.

Does disclaiming an inheritance mean I owe less tax?

Not necessarily, and this is highly fact-specific. Because tax consequences depend on the type of asset, how the disclaimer is structured, and your personal circumstances, this is an area where you should get tailored advice rather than assume a general rule applies to you.
