Key takeaways
  • For life insurance, a designation in a will has no effect against a designation made later than the will.
  • For RRSPs, RRIFs and similar plans, a will designation must refer expressly to the plan, and the latest valid designation controls.
  • Designated money generally stays outside the estate, but a dependant's support claim can still reach it.

You are going through a loved one's papers and find a problem. The will leaves everything to one person, but the life insurance, RRSP, RRIF or pension form names someone else. It is natural to ask which document the insurer or plan administrator will follow.

In Ontario the answer depends on the type of asset, because insurance, registered plans and pensions each follow slightly different rules, and some have exceptions for spouses. This article explains the general picture so you know what questions to ask.

Life insurance: the later designation wins

A person insured under a life insurance contract may name a beneficiary in the contract itself or by a declaration. A declaration is an instrument signed by the insured and endorsed on the policy; it identifies the contract or describes the insurance, and it designates or changes a beneficiary. Unless the designation is irrevocable, the insured may change or revoke it at any time by a declaration.

A beneficiary can also be named in a will. However, a designation in a will has no effect against a designation made later than the will. So if the will names a child but a form signed after the will names a spouse, the later form controls. If a will containing an insurance designation is revoked, by operation of law or otherwise, the designation in it is revoked too.

An insurer may also, subject to the Authority rules, restrict or exclude the insured's right to designate beneficiaries in the contract, so the policy wording matters.

When "irrevocable" really is irrevocable

An insured may name a beneficiary irrevocably in the contract or in a declaration, but not in a will, that is filed with the insurer during the insured's lifetime. While that beneficiary is living, the insured cannot change or revoke the designation without the beneficiary's consent.

If an "irrevocable" designation is made in a will, or in a declaration that is not filed with the insurer, it has the same effect as an ordinary revocable designation.

RRSPs, RRIFs and other plans

For plans other than insurance, such as RRSPs, RRIFs and pensions, a participant may designate a person to receive the benefit payable on death. A designation in a will is effective only if it relates expressly to a plan, either generally or specifically. Between designations, a later one revokes an earlier one to the extent they are inconsistent, so whichever valid designation, in the will or on the plan form, is made last controls. Ontario pensions are different: when a member dies before the pension starts, the spouse is entitled to the pre-retirement death benefit ahead of any designated beneficiary, unless the spouse has waived it, as explained below.

The plan administrator is discharged on paying the benefit to the person designated, and that person may enforce payment. This is why administrators usually follow the paperwork on file.

There is an exception. These plan-designation rules do not apply to a designation to which the Insurance Act applies, such as an insurance-company RRSP or annuity. Those follow the insurance rules above.

Pensions, "estate" designations and other special cases

The pension rules cover Ontario-registered plans only. Federally regulated plans and plans in other provinces can follow different rules, so confirm which law governs the plan.

Outside the estate, but not always out of reach

When a beneficiary is designated, life insurance money does not form part of the insured's estate and is not subject to the claims of the insured's creditors. Designated assets also generally skip probate for Estate Administration Tax purposes, including registered plans with a beneficiary designation.

A dependant's support claim is different. For that claim, life insurance owned by the deceased and amounts payable under a plan designation are deemed part of the net estate, so a dependant can reach designated assets. Such an application generally cannot be made more than six months after the grant of letters probate or administration, although the court may allow a later application against any part of the estate still undistributed.

What to do next

Conflicting documents can lead to disputes, and the dates and wording matter. A lawyer can review the documents and explain who is likely to be entitled.

Frequently asked questions

If my parent's will names me but the insurance form names my sibling, who gets the money?

A designation in a will has no effect against a designation made later than the will. So if the insurance form was signed after the will, the form controls. If the will came later, how this applies depends on the documents, so it is worth confirming with a lawyer. The dates on each document are the first thing to check.

Does divorce cancel an ex-spouse as beneficiary on insurance or an RRSP?

Divorce revokes gifts to a former spouse in a will. That rule is about wills, and the provisions reviewed do not automatically cancel an insurance or RRSP designation, so those forms generally need to be updated. A lawyer can confirm how it applies to your situation.

Can the estate trustee override a named beneficiary?

Generally no, because designated life insurance does not form part of the estate. For a non-insurance plan, the administrator is discharged on paying the benefit to the person designated. If the designation names the estate or heirs, though, the money goes through the estate.

Can a dependant still make a claim if a beneficiary was named?

Yes. For a dependant's support claim, life insurance and plan-designated amounts are deemed part of the net estate. The application generally cannot be made more than six months after the grant of probate, subject to the court's discretion.
