When a child with a disability has a Registered Disability Savings Plan, it's usually a parent who opened it and acts as the plan holder. Families rarely stop to ask what happens to that plan if the parent-holder dies first — and by the time the question comes up, it's often too late to answer it the easy way. Naming a successor holder in advance is one of the simplest, lowest-cost planning steps a family with an RDSP can take, and one of the most commonly missed.

Holder vs. Beneficiary: Two Different Roles

Understanding this distinction is the key to understanding why successor holder planning matters.

RoleWho it usually isWhat they do
BeneficiaryThe person with the disability, for whose benefit the plan existsReceives the eventual payments from the plan
HolderOften a parent, when the beneficiary is a minor or lacks capacityHas legal authority to make decisions about the plan — contributions, investments, withdrawals

The beneficiary doesn't change when a holder dies. The problem is that, without a named successor, no one automatically has authority to act as the new holder the moment the original holder dies — and an RDSP generally can't operate normally without someone in that role.

What Happens Without a Successor Holder Named

If the holder dies without a successor holder in place, the plan doesn't disappear, but it can effectively be frozen from a decision-making standpoint until someone establishes legal authority to become the new holder. Depending on the beneficiary's age and capacity, that might mean:

None of these gaps are catastrophic on their own, but they all take time — time during which contributions, investment decisions, and grant/bond applications may be on hold.

How to Name a Successor Holder

  1. Check with the RDSP issuer about their specific process — successor holder designations are typically made through the plan documentation with the financial institution holding the plan, not through a will alone.
  2. Choose someone who can realistically take on the role — usually the other parent, but it could be another trusted family member, particularly in single-parent families.
  3. Coordinate this with your broader estate plan, including your will and any Henson trust structure, so the people managing different parts of your family member's financial life are working from the same plan.
  4. Revisit the designation periodically — family circumstances change, and a successor holder named years ago may no longer be the right choice.

Successor Holder Planning Checklist

Why This Belongs in the Same Conversation as Your Will

A successor holder designation and a will do different jobs, but they're planning for the same underlying risk — what happens to this family member's financial support if something happens to the person currently managing it. Reviewing them together, rather than treating the RDSP as something separate from "the estate plan," is the more reliable way to make sure nothing falls through the cracks.

Frequently asked questions

Can I name a successor holder in my will instead of through the RDSP issuer?

Generally, no — successor holder designations are typically made directly with the financial institution holding the plan, following their specific process, not through a will provision alone. Check directly with the issuer to confirm their requirements.

What if the beneficiary is an adult with capacity?

If the beneficiary has the capacity to manage their own affairs, they may be able to become their own plan holder at any point, which reduces (though doesn't necessarily eliminate) the need for successor holder planning — this is worth discussing directly with the RDSP issuer.

Does naming a successor holder cost anything?

This is a question for the specific RDSP issuer, as processes and any associated administrative requirements can vary by financial institution.

What if both parents could die at the same time?

This is exactly the kind of scenario worth planning for explicitly — through a combination of successor holder designation, your wills, and, where appropriate, a Henson trust or guardianship planning for the beneficiary, so there's a clear next step no matter what happens.
