Wills for Blended Families in Canada
For Canadians in blended families — current spouse plus children from previous relationships — estate planning has a specific structural challenge. The standard "leave everything to spouse, then to children" doesn't work because the surviving spouse may not provide for the deceased's children. This article covers the common solutions.
The core problem
Standard will structure (everything to spouse, then to children on second death) assumes:
- Surviving spouse will continue to provide for children of deceased
- Surviving spouse will leave assets to children of both spouses in their own will
For first marriages with shared children, usually works. For blended families:
- Surviving spouse may have children from previous marriage with conflicting interests
- Surviving spouse may remarry and inherit goes to new spouse
- Surviving spouse's own will may not provide for stepchildren
The deceased's children may inherit nothing despite the deceased's clear intent.
Common solutions
Spousal trust. Surviving spouse receives income from trust during their lifetime; principal passes to deceased's children at spouse's death. Protects both groups.
Direct bequests to children. Specific bequests directly to children from the estate, with residue to current spouse. Children receive guaranteed amount.
Life insurance. Life insurance with children as beneficiaries provides for them outside the estate. Bypasses the "spouse inherits then disinherits" risk.
Separate property structure. Keeping certain property in deceased's sole name (not joint with current spouse) ensures it passes per will rather than to spouse by survivorship.
Cohabitation/marriage agreement. Pre-nuptial or cohabitation agreement clarifies property rights and inheritance expectations between spouses.
When DIY doesn't work
Blended families are among the situations where lawyer-drafted wills are clearly worth the cost.[1] DIY templates typically don't include spousal trust language, complex contingencies, or specific blended-family protections.
Cost: $500-$2,000+ for lawyer-drafted blended-family will. Compared to potential lost inheritance for children of first marriage (potentially hundreds of thousands or more), modest investment.
What to discuss with spouse
Important to have explicit conversation:
- Each spouse's wishes for their own children's inheritance
- How estate should be structured
- Whether spousal trust appropriate
- Coordination of beneficiary designations
- Joint property arrangements
- Children's expectations and communications
Tension is common but addressing it directly through proper planning is much better than letting it explode after one spouse's death.
What we focus on at It's Simple Will
It's Simple Will supports blended families but for complex spousal trust structures, we encourage lawyer involvement. The will questionnaire can produce a baseline; lawyer review and refinement for complex blended situations.

Frequently asked questions
What's the core challenge in blended family wills?
Tension between current spouse's expectation of inheritance and children-of-previous-marriage's expectation. Without specific planning, current spouse inherits everything (if named primary), then on second death, that spouse's will distributes — typically not to the deceased's children of previous marriage. The deceased's children may inherit nothing.
What's a spousal trust?
Trust structure where surviving spouse receives income from estate during their lifetime; the principal eventually passes to children (or other beneficiaries) at the spouse's death. Protects both groups — surviving spouse has income; children eventually inherit the principal.
When does a spousal trust fit?
When testator wants current spouse to have lifetime financial support but wants children of previous marriage to eventually inherit. Common in second marriages with children from first marriages.
What about direct bequests to children?
Common approach — specific bequests directly to children from estate (not through spouse), with residue to current spouse. Children receive guaranteed amount; spouse receives the rest.
What about life insurance?
Effective tool. Life insurance with children as beneficiaries provides for them outside the estate. Spouse can be primary estate beneficiary; children receive insurance directly. Solves the "spouse inherits then disinherits children" risk.
Lawyer or DIY?
Lawyer strongly recommended. Blended family planning is among the more complex areas; DIY templates often miss key protections. Cost ($300-$1,500+) justified by the stakes.
