Setting Up a Trust for a Minor Child in Your Will
Children cannot legally manage money or property. If a minor inherits without a plan, the funds are usually frozen under court supervision and handed over in one lump sum when they come of age — often far too young to handle it. A trust set up in your will (a testamentary trust) solves this by putting a trusted adult in charge until your child is ready. This article explains how it works. It is general information, not legal advice.
What is a testamentary trust for a minor?
A testamentary trust is created by your will and comes into effect when you die. Instead of leaving money directly to a child, you leave it to a trustee who holds and manages it for the child's benefit.
The trustee follows the rules you set: spending on the child's needs, investing the funds, and releasing capital at the ages or milestones you choose. The child benefits throughout, but does not control the money until your chosen time.
Why not just leave money to my child directly?
A direct gift to a minor cannot be paid to the child. It typically falls under court control until the age of majority, with limited flexibility and the cost and formality of court oversight.
Worse, the child usually receives the entire balance the day they reach 18 or 19. Few young adults are prepared to manage a significant sum responsibly at that age, and there is no further protection once it is paid out.
How do I decide the payout ages?
You set the schedule. Many parents stagger it — for example, releasing a portion at 21, more at 25, and the balance at 30 — so a mistake at one age does not consume the whole inheritance.
You can also give the trustee discretion to pay for specific needs (education, a home down payment, medical costs) before the scheduled ages. This blends protection with practical support.
- A single payout at a chosen age (such as 25).
- Staggered payouts across several ages (21, 25, 30).
- Discretionary payments for education, health, or housing.
- Full trustee discretion until a final distribution age.
Who should I choose as trustee?
Pick someone responsible with money, organized, and likely to act in your child's interest over many years. It can be the guardian, but it does not have to be — separating the roles adds oversight.
Name a backup trustee, and consider a professional trustee (a trust company) for large funds or where no individual is ideal. Trustees can usually be paid a reasonable fee for the work.
Are there tax or cost considerations?
Testamentary trusts have specific tax treatment that has changed over the years; in Canada most are now taxed at the top marginal rate, though a graduated-rate estate and qualified disability trust are exceptions. In the US, trust taxation has its own rules and brackets.
There are also administration costs — accounting, possibly trustee fees. For most families the protection is well worth it, but confirm the tax treatment with an advisor for larger amounts.
How does iFinallyWill set up a trust for a minor?
iFinallyWill lets you create a testamentary trust as part of your will: name the trustee and backup, set the payout ages, and grant discretion for needs like education — all tailored to your jurisdiction.
Lifetime updates mean you can adjust ages or trustees as your child grows. For very large estates or complex tax planning, treat the will as a strong base and confirm the structure with a professional.
Frequently asked questions
- What is a testamentary trust?
- A trust created by your will that takes effect on your death. A trustee manages the assets for a beneficiary — commonly a minor child — and distributes them according to the rules you set out in the will.
- At what age should my child receive the money?
- There is no single right answer. Many parents stagger distributions (for example 21, 25, and 30) so the whole inheritance is not received at once, with trustee discretion to help with needs in between.
- Can the guardian and trustee be the same person?
- Yes, but they do not have to be. Splitting the roles lets one person raise the child while another manages the money, which adds a useful check on how funds are spent.
- Is a trust expensive to run?
- There are some accounting and possible trustee costs, and specific tax rules apply. For most families the protection outweighs the cost, but confirm the tax treatment for larger amounts with an advisor.
