Estate Planning for Blended Families in BC
Stepchildren, ex-spouses, children from different relationships — blended families are where estate planning matters most, because the default rules rarely match anyone's wishes.
Key Takeaways
- Stepchildren do NOT inherit under intestacy unless legally adopted
- Intestacy splits assets between your spouse and children from other relationships — often forcing a home sale
- Both your current spouse and your children can challenge your will
- A will with proper planning is essential — intestacy rules almost never work for blended families
- Trusts, life insurance, and beneficiary designations are key tools
Why blended families need a will more than anyone
If you have a simple family — one spouse, shared children — BC's intestacy rules are reasonably fair. But for blended families, they create chaos.
Under WESA's intestacy rules, when you die with a spouse AND children from a previous relationship:
- Spouse gets the first $150,000 (preferential share)
- Spouse gets 50% of the remainder
- Children from the other relationship split the other 50%
The stepchildren gap
Stepchildren who have not been legally adopted have no inheritance rights under BC intestacy law. This means:
- If you die without a will, your stepchildren get nothing — even if you raised them from childhood
- Stepchildren cannot bring a wills variation claim under WESA
- Only a will can provide for stepchildren you consider your own
If you want your stepchildren to inherit, you must explicitly include them in your will.
The competing claims problem
In a blended family, your estate faces potential claims from multiple directions:
- Current spouse: Can vary your will if they feel inadequately provided for
- Children from current relationship: Same variation rights
- Children from previous relationship: Same variation rights
- Ex-spouse: Generally cannot vary your will (spousal status ends 2 years after separation), but may have claims under a separation agreement or court order
Balancing these competing interests is exactly why blended families need a lawyer — not a template.
Strategies that work
Life interest trust (spousal trust)
Leave the family home (or other assets) in a trust that gives your current spouse the right to live there for their lifetime. After the spouse dies, the home passes to your children. This protects the spouse's housing while preserving the asset for your children.
Life insurance
Use life insurance to equalize distributions. For example: leave the house to your spouse, and take out a life insurance policy with your children as beneficiaries. This avoids forcing a home sale and gives everyone their share.
Beneficiary designations
Use RRSP, TFSA, and insurance beneficiary designations strategically. These assets pass outside the will and outside probate, giving you more control over who gets what. How designations work
Marriage/cohabitation agreements
A domestic contract can define what each spouse is entitled to, which can reduce the risk of a wills variation claim. These agreements should be prepared with independent legal advice for both parties.
Clear documentation
If you're providing less for certain family members, document your reasons. A letter kept with your will explaining your rationale can help defend against variation claims — especially if the reasons are valid and rational.
Common mistakes in blended family estate planning
- "Leave everything to my spouse — they'll take care of the kids": They might. But they might remarry, change their mind, or face their own financial pressures. There's no legal obligation for your spouse to pass anything to your children.
- Not updating after remarriage: Your old will (made for your first spouse) may not reflect your current wishes. WESA doesn't revoke your will upon marriage.
- Assuming intestacy works: It almost never does for blended families.
- Not accounting for both sides: Both you and your current spouse should have coordinated estate plans that consider each other's children from previous relationships.
Frequently asked questions
Do stepchildren inherit in BC if there's no will?
No. Only biological and legally adopted children inherit under intestacy. You must include stepchildren in your will.
Can stepchildren challenge a will in BC?
Only if legally adopted. Non-adopted stepchildren cannot bring a wills variation claim under WESA.
What happens to the family home in a blended family without a will?
The spouse gets $150,000 + 50% of the rest. Children from a previous relationship get the other 50%. If the home is the main asset, a forced sale may be necessary.
