Writing a Will with Children — Guardian, Trust, and Age-Triggered Distributions

A Canadian Will for parents with minor children has specific requirements beyond a standard Will. This guide covers the essentials — guardian, trust, distribution age, and common pitfalls.

Element 1 — Guardian #

The most important decision for parents with minor children.

What a guardian does: Takes over parental responsibility if both parents die.

Selection considerations:

• Will actually raise the children with values you'd want
• Geographic stability (won't require children to move far)
• Age and health (won't predecease while children are still minors)
• Willingness (must agree to take on the role)
• Existing relationship with children
• Family fit and dynamic
• Financial capacity (can be different from trustee, so financial capacity less critical)

Asking:

• Discuss in advance
• Confirm willingness
• Specific to backup if primary cannot
• Update if circumstances change

Common pitfall — naming a couple:

"We name my brother John and his wife Sarah as guardians." Problem if John and Sarah divorce. Better — name an individual (with backup) or specify what happens if the couple separates ("if John and Sarah are no longer married at the time of my death, John alone shall be guardian, or, failing John, then [backup]").

Element 2 — Trust #

Children under the provincial age of majority cannot directly own most property.

Age of majority:

• BC, NB, NL, NS, NWT, Nunavut, Yukon: 19

The trust:

• Trustee holds the inheritance
• Funds used for child's benefit (education, living expenses, health, etc.)
• Specific termination — funds distributed to child at designated age

Trustee role:

• Manage the funds (invest, account for expenses)
• Use funds for child's benefit per Will provisions
• Account to beneficiaries upon coming of age
• Specific to fiduciary duties under provincial trust law

Element 3 — Distribution age #

When does the child receive the funds outright?

Common patterns:

Lump sum at age of majority:

• 18 or 19 depending on province
• Simple
• Risk: young adult may not have judgment for substantial sum

Staggered:

• 1/3 at 21, 1/3 at 25, 1/3 at 30
• Most common pattern
• Balances independence with risk reduction

Single age later:

• All at 25 or 30
• Trustee manages longer
• Trust administration costs higher

Lifetime trust with trustee discretion:

• Funds remain in trust throughout beneficiary's life
• Trustee makes discretionary distributions
• Used for special-needs beneficiaries or significant wealth
• Specific to specific trust types under federal Income Tax Act

Conditional distributions:

• "1/3 at 21, 1/3 at completion of post-secondary, 1/3 at 30"
• More elaborate; specific drafting required
• See conditional bequests Canada

Element 4 — Backup guardian and trustee #

Both critical:

Backup guardian: What if primary guardian dies, is unable, or unwilling? Named backup steps in. Without backup, court appoints if no agreement.

Backup trustee: Same — what if primary trustee dies, is unable, or unwilling?

Cascading backup: "I name my sister Mary as guardian; if she is unable or unwilling, my brother John; if he is also unable, my cousin Lisa."

Element 5 — Letter of wishes for guardian #

A non-binding letter accompanying the Will provides specific guidance to the guardian about:

• Values you'd want imparted
• Religious upbringing preferences
• Educational priorities
• Specific traditions to maintain
• Specific to discipline and parenting style preferences
• Specific to children's specific needs you know about

The letter doesn't bind the guardian legally but provides reference. Stored with the Will and given to the guardian upon their appointment.

Specific to particular situations #

Single parent #

Same elements apply. Specific consideration if other parent is alive — court typically defaults to surviving parent unless specific reasons to override. Document specifically if you want guardian to be other than surviving parent.

Blended family (children from different relationships) #

• Specific provisions for each child
• Specific to ex-spouse considerations
• Specific to step-parent considerations
• May warrant specific legal advice

Children with special needs #

• Specific trust structures (a Henson trust, drafted against the particular benefits program — whether the interest counts as an asset depends on that program's wording)
• Specific guardianship of property considerations
• Specific to ongoing care planning

Adult children with continuing dependency #

• Specific provisions for dependent adult children
• Specific to provincial dependant relief considerations
• Specific to disability or other dependency

What to avoid #

No guardian named. Court appoints; outcome may not match your preferences. Always name primary AND backup.

Guardian only verbally agreed. Document in writing in the Will.

Trust extending too long. Children at 30 don't need their inheritance held in trust; freedom and access are appropriate.

Trust ending too early. Lump sum at 18 means $500,000 to a 18-year-old who may not have judgment.

Same person as guardian AND trustee. Reduces accountability; one person both raises children and manages their money.

Failing to update. Children grow up; siblings come and go; guardian/trustee circumstances change. Update at major life events.
