Who Inherits When a Common-Law Spouse and Stepchildren Both Claim the Estate?
In BC, common-law spouses have the SAME inheritance rights as married spouses after 2 years of cohabitation. Under WESA intestate succession, the surviving spouse receives a preferential share ($150,000 when there are children from a prior relationship) plus 50% of the remainder. The children share the other 50%. If there IS a will leaving everything to the spouse, the children can still challenge under WESA Section 60 within 180 days.
For blended families in Langley, Coquitlam, and the Fraser Valley, the intersection of inheritance and emotion is a high-speed collision. On one side is the surviving common-law partner or second spouse, often the primary support system for the deceased during their final years. On the other side are the adult children, who view the family home and the estate assets as their biological birthright.
The BC Supreme Court is frequently the arbiter of these disputes because British Columbia has some of the strongest protections for common-law spouses in the country. Many adult children are shocked to learn that a parent's 'girlfriend' or 'boyfriend' of three years has the same legal standing as a wife or husband of forty years. Conversely, many surviving spouses are devastated to find that their WESA spouse rights are diluted by the existence of children they barely know.
The fundamental question is one of adequate provision. How does the law balance the needs of a survivor who built a life with the deceased against the moral claim of children who represent the deceased's legacy? Without a clinical, forensic map of common-law inheritance BC rules, these families almost always descend into toxic litigation.
Why Do Blended Families Tear Apart Over Inheritance?
Blended family estate disputes are the most emotionally volatile probate cases in BC because they pit two legitimate claims against each other: the surviving spouse's need for security and the children's sense of birthright from their biological parent.
In my years as a Forensic Real Estate Specialist in the Fraser Valley, I've seen these three scenarios play out repeatedly, each ending in a fractured family:
"The Late-Arrival Stepmother"
Dad married Linda in Surrey three years ago. She's 15 years younger. Dad's will, signed just months before he died, leaves her everything—the house, the car, the savings. We're his biological children; we grew up in that house. Linda says she's 'just following Dad's wishes,' but we feel like our family history has been erased by a stranger. How can she take OUR family home?
"The Invisible Common-Law Partner"
I lived with Robert in Coquitlam for 14 years. I paid half the mortgage and took him to every dialysis appointment for a decade. His kids from his first marriage showed up at the funeral with a lawyer. They called me 'the tenant' and said I had 30 days to move out. They don't believe I have rights because we never had a marriage certificate. I'm a common-law spouse with full rights—but they've turned my grief into a war.
"The Remarriage Leak"
Mom remarried after Dad died. Stepdad was wonderful for 10 years in their Burnaby condo. Then Mom died. Stepdad inherited everything under her will. Now Stepdad is remarrying AGAIN. Our inheritance—Mom's jewelry, the family photos, Dad's watch—is now legally owned by a man who is giving it to his new wife. Our family's wealth is leaking into a different family tree entirely.
The blended family estate crisis is rarely about greed. It is about validation. The spouse wants their years of care recognized; the children want their biological connection honored. When the law (WESA) is applied clinically, it often ignores these emotional needs, leading to will variation claims that cost the family hundreds of thousands in legal fees.
What Are a Common-Law Spouse's Inheritance Rights in BC?
After 2 years of continuous cohabitation, a common-law spouse in BC has identical inheritance rights to a legally married spouse under WESA. This includes the preferential share in intestacy, the right to challenge a will under Section 60, and the right to a division of family property under the Family Law Act.
The 2-year threshold is the most important number for common-law couples in the Fraser Valley. In the eyes of the BC Supreme Court, the 24th month of cohabitation is the moment a 'girlfriend' or 'boyfriend' becomes a legal spouse with a massive claim on the estate.
- Proving the Relationship: If the biological children challenge the common-law status, the survivor must provide forensic evidence: a shared address in Langley, joint utility bills, public representation as a couple ('this is my partner'), and shared finances.
- WESA Standing: Once the 2-year mark is met, the common-law spouse is a 'spouse' under WESA. They cannot be disinherited without a valid, rational reason. If the will leaves them out, they have a near-certain chance of success in a variation claim.
- Family Property Rights: Beyond probate, the Family Law Act allows a common-law spouse to claim 50% of any 'family property' built during the relationship, even if it's held in the deceased's name alone.
The misconception that 'we're not married, so I'm safe' has ruined more family legacies in Coquitlam than almost any other legal error. Common-law rights in BC are among the strongest in the world.
What Is a Life Estate and How Does It Protect Both Sides?
A life estate is a legal arrangement where the surviving spouse has the right to live in the family home for the rest of their life, but the property automatically passes to the children upon the spouse's death. It's the most elegant solution for blended families because it provides security for the spouse WITHOUT permanently disinheriting the children.
In the Fraser Valley, real estate is almost always the largest asset. A life estate solves the "who gets the house" fight by splitting time, not money.
- Security for the Spouse: The survivor can never be evicted. They can live in the house in Coquitlam or Surrey until they pass away or move into a care facility. They are responsible for maintenance, taxes, and insurance.
- Certainty for the Children: The spouse cannot sell the house or leave it to someone else in their own will. The children know that eventually, the family asset will return to them. This removes the fear of 'remarriage leakage.'
- Bypassing Probate: A properly structured life estate (or an 'Altered Property Trust') can allow the house to pass directly to the children upon the spouse's death, avoiding the 1.4% probate fees BC tax.
The emotional benefit is massive. It moves the siblings and the spouse from being adversaries to being 'partners in the property.' It's the strategy we recommend most often for second marriage estate planning.
What Are the Four Estate Planning Tools for Blended Families?
Blended families in BC need four specific estate planning tools to prevent conflict: a custom blended family will, a life estate or trust, a cohabitation agreement, and specific beneficiary designations on registered accounts.
Tool 1: The Blended Family Will
A 'simple will' is a disaster for blended families. You need a document that explicitly addresses stepchildren inheritance rights. It should include a 'Memorandum of Wishes' that explains the reasoning—this is the first line of defense if the children challenge under WESA Section 60. If you are disinheriting a child, you must explain why in a rational, consistent way.
Tool 2: Testamentary or Altered Property Trusts
Trusts are the forensic firewall. You can put the Langley property into a trust where the spouse is the 'income beneficiary' (gets to live there/collect rent) and the children are the 'capital beneficiaries' (get the house eventually). This prevents the spouse's future creditors or new partners from ever touching the family wealth.
Tool 3: Cohabitation/Marriage Agreements
In BC, you can contract out of WESA. A cohabitation agreement signed before or during the relationship in Surrey can specify that neither party will challenge the other's will. For this to hold up in the BC Supreme Court, it must be fair and both sides must have their own lawyers.
Tool 4: Equalization via Beneficiary Designations
The easiest way to keep the peace is to give the house to the spouse and give something of equal value to the kids. Name the children as direct beneficiaries on a $500,000 life insurance policy. Since this bypasses the estate and probate, they get their money immediately, reducing their incentive to sue for a share of the house.
What Happens When Both Sides Hire Lawyers?
When a blended family inheritance dispute escalates to litigation, both sides face legal fees of $25,000-$75,000 each, a timeline of 12-24 months, and a family relationship that is almost certainly permanently destroyed.
The irony of estate litigation BC is that families fight over a $500,000 difference in shares, only to spend $150,000 combined on legal fees. In the end, the lawyers are the only ones who truly inherit.
If you are a disinherited child BC claimant or a common-law spouse under fire in Richmond, the court will almost certainly order you into mediation. Mediation costs $5,000 to $10,000 and has an 80%+ success rate in BC. It is the only path that allows you to be a family again. If you skip mediation and go to a full trial in the BC Supreme Court in New Westminster, expect a judge who is frustrated by the family's inability to find a judicious compromise.
The Map Maker's Strategy
"Blended family probate is the most painful work I do. I've sat in rooms where a widow of 15 years is being told by her stepchildren that she needs to leave the house she helped pay for. Both sides have a point. Both sides are hurting. My job isn't to pick a side — it's to map the tools that protect everyone: a life estate that lets the spouse stay while guaranteeing the children's inheritance, and a roadmap that prevents the $100K legal battle. The best estate plans for blended families aren't about winning — they're about everyone being able to sit at the same table at Christmas. If you don't have that map, the law will write a very cold one for you."

Frequently Asked Questions
Do common-law spouses inherit in BC?
Yes. Under the Wills, Estates and Succession Act (WESA), common-law partners in British Columbia have identical inheritance rights to legally married spouses, provided they have lived in a marriage-like relationship for at least two continuous years immediately prior to the date of death. This includes the right to a 'preferential share' of an intestate estate and the standing to challenge a will under Section 60 if they are disinherited. To verify your status, consult the BC Laws (WESA) registry.
What is the preferential share for a second spouse in BC?
The preferential share is the first portion of an estate that goes to a surviving spouse before any remainder is divided with children. In BC, if the deceased had children from a previous relationship (a blended family), the spouse's preferential share is $150,000. If all children are shared between the deceased and the surviving spouse, the share increases to $300,000. This $150,000 difference is a common source of financial crisis for surviving spouses in Langley or Surrey.
Can stepchildren inherit from a step-parent in BC without a will?
No. Under BC's intestate succession rules, stepchildren do not have an automatic right to inherit from a step-parent unless they have been legally adopted. If there is no will, the estate passes to biological or adopted children only. However, stepchildren may have a claim if they can prove they were financially dependent or if a promise of inheritance was made. For more on these complex claims, visit the Supreme Court of BC website.
What is a life estate in BC probate?
A life estate is a legal arrangement, often used in Fraser Valley blended families, where a surviving spouse is given the right to live in the family home for the duration of their life. Upon the spouse's death or relocation to care, the property title automatically transfers to the deceased's children. This protects the spouse's housing security while guaranteeing the children's eventual inheritance of the family asset.
Can the deceased's children challenge a will that leaves everything to a new spouse?
Yes. Under WESA Section 60, biological or adopted children can apply to the BC Supreme Court to vary a will if it does not make 'adequate provision' for them. The court considers the parent's 'moral obligation' to their children. Even if the will is technically valid, a judge can redistribute the estate to ensure fairness between the new spouse and the children. Learn more about the WESA 60 challenge protocol.
What is a cohabitation agreement and does it affect inheritance?
A cohabitation agreement is a contract between common-law partners that defines how property will be divided upon separation or death. In BC, a properly drafted agreement can waive or limit spousal inheritance rights, overriding the default rules of WESA. For the agreement to be enforceable in the BC Supreme Court, both parties must have received independent legal advice and made full financial disclosure. Resources are available at Seniors First BC.
How do I protect both my spouse and my children in my BC will?
The most effective strategy is 'Equalization through Bypassing.' This involve using tools like a life estate for the family home in Coquitlam, which protects the spouse, while naming the children as direct beneficiaries on life insurance or registered accounts (RRSPs/TFSAs). Because these assets pass outside of the will, they provide immediate liquidity to the children while the spouse remains secure in the home.
How much does blended family estate planning cost in BC?
A comprehensive blended family estate plan—including a custom will, life estate trust, and cohabitation agreement—typically costs between $2,500 and $5,000. While higher than a standard 'simple will,' this investment prevents probate litigation that can cost each side $50,000 or more in legal fees. For families in Abbotsford or Chilliwack, the cost of planning is a fraction of the cost of conflict.
