In British Columbia, you become a common-law spouse by living with your partner in a marriage-like relationship for at least two continuous years. There is no ceremony, no registration, and no form to file. Once you cross that two-year line, the province’s Family Law Act automatically treats you as a spouse, with the same property division, support, and inheritance rights as a married couple.1British Columbia Laws. British Columbia Code – Family Law Act The automatic part is what trips people up, so it’s worth knowing exactly when the clock starts, what a court looks for, and what rights switch on the moment you qualify.
The Two-Year Cohabitation Rule
Section 3 of the Family Law Act sets the test: two people who have lived together in a marriage-like relationship for a continuous period of at least two years are spouses for the purposes of the Act.1British Columbia Laws. British Columbia Code – Family Law Act The clock starts the day you move in with the intention of functioning as a couple, not simply as roommates sharing rent.
Continuity does not require a perfect streak. A brief separation followed by reconciliation generally does not reset the timeline if the overall pattern shows a relationship both of you intended to carry on. What matters is the shape of the whole, not a few interrupted weeks.
Hitting the two-year mark changes your legal position substantially. Under section 81 of the Act, each spouse gains an undivided half interest in all family property and becomes equally responsible for family debt.2British Columbia Laws. British Columbia Code – Family Law Act – Property Division Family property includes the home you share, savings built up during the relationship, vehicles bought while you were together, and pensions. The default split is the same one a divorcing couple would face.
What Counts as a Marriage-Like Relationship
Sharing an address is necessary, but it is not enough. Courts look at the full picture of your domestic life to decide whether the relationship genuinely resembles a marriage. The leading test comes from Molodowich v. Penttinen, and Canadian courts still work through its seven factors:
- Shelter: whether you share a home and treat it as “our place” rather than one person staying at the other’s apartment.
- Sexual and personal behaviour: whether there is an intimate relationship and whether you present yourselves as a couple.
- Domestic services: whether you share household work like cooking, cleaning, and maintenance.
- Social activities: whether you socialize together, attend events as a couple, and share a social circle.
- Community perception: whether friends, family, and neighbours see you as partners.
- Finances: whether you pool income, share expenses, or support each other financially.
- Children: whether you raise children together or take on a parental role with each other’s children.
No single factor decides it. A couple with separate bank accounts can still qualify if everything else points to a shared domestic life, and sharing finances alone does not make you common-law if the rest of the relationship looks more like a business arrangement. Every relationship is judged on its own facts.
If You Have a Child Together
Having a child together shortens the timeline for one specific purpose. Under section 3(2) of the Family Law Act, a person who has lived with a partner in a marriage-like relationship for less than two years still qualifies as a spouse for Part 7 support claims if the couple has a child together.1British Columbia Laws. British Columbia Code – Family Law Act A parent who stayed home with a newborn can seek spousal support even if the relationship lasted only a few months.
The shorter route does not unlock property or pension division. The statute specifically excludes Part 5 (property) and Part 6 (pension) from the child-based exception.1British Columbia Laws. British Columbia Code – Family Law Act You still need the full two years of cohabitation to claim an equal share of family assets.
Evidence That You Qualify
Because common-law status happens by operation of law, there is nothing to register and no certificate to receive. The question only arises when something is at stake: a benefit application, a dispute with your partner, an estate matter. At that point you need documents that show a shared domestic life over time. The strongest proof tends to be:
- A joint lease or mortgage listing both of your names.
- Utility accounts in either or both names at the same address, dated across the period you lived together.
- Joint bank accounts or shared credit cards showing financial interdependence.
- Insurance policies, pension plans, or employer benefits that name your partner as a beneficiary.
- Government correspondence, CRA notices, or driver’s licences showing a continuous shared address.
A note on one form people sometimes assume does the job: the federal Statutory Declaration of Common-Law Union (IMM 5409) is designed for immigration applications administered by Immigration, Refugees and Citizenship Canada. Completing it does not create or confirm your status under BC provincial law. Your standing under the Family Law Act depends on meeting the cohabitation and relationship test, not on filing a particular document. If you do sign a sworn declaration about your relationship for any purpose, the information must be truthful. A false statement in a sworn declaration is perjury under section 131 of the Criminal Code.3Justice Laws Website. Criminal Code – Perjury
What Rights Switch On
Property and Debt
The equal-split rule under section 81 applies to “family property,” meaning essentially everything either of you owns at the date of separation that was acquired during the relationship.2British Columbia Laws. British Columbia Code – Family Law Act – Property Division Section 85 carves out several categories of excluded property that you keep as your own: assets you owned before moving in together, inheritances, gifts from third parties, personal injury settlements (with some exceptions), and property purchased with the proceeds of any of these.
Here is the part that surprises people. If excluded property increases in value during the relationship, that increase is family property and gets split equally.2British Columbia Laws. British Columbia Code – Family Law Act – Property Division A condo worth $400,000 when you moved in together that is worth $600,000 at separation keeps its original $400,000 with the owner, but the $200,000 gain is family property. Excluded property stays excluded even if you put it into joint names, though the person claiming the exclusion carries the burden of proving it.
Inheritance
Once you qualify, BC’s Wills, Estates and Succession Act treats you the same as a married spouse for inheritance purposes. If your partner dies without a will and has no children, you inherit the entire estate.4British Columbia Laws. British Columbia Code – Wills, Estates and Succession Act If children are involved, you receive all household furnishings plus a preferential share of the estate before the remainder is divided, and you have a right to claim the family home as part of your share. Even where a will exists, a common-law spouse can apply to vary a will that does not make adequate provision for their maintenance and support.
One timing point matters here. The two-year cohabitation requirement under WESA must be met immediately before the partner’s death. A relationship that ended 18 months in does not qualify, even if the federal 12-month tax threshold had already been crossed.
Healthcare Decisions
If your partner becomes unable to consent to medical treatment, you sit at the top of the ranked list of temporary substitute decision makers under BC’s Health Care (Consent) and Care Facility (Admission) Act, ahead of adult children, parents, and siblings.5Government of British Columbia. Duties of a Substitute Decision Maker That authority is reactive and narrow: it covers specific health care decisions when a provider calls on you, and nothing else. Couples who want broader and more proactive authority usually set up representation agreements while both partners are healthy.
The Federal Timeline Is Different
The Canada Revenue Agency uses a shorter clock than BC does. The CRA considers you common-law after 12 months of continuous cohabitation in a conjugal relationship, regardless of whether you have reached the provincial two-year mark. Once you cross that federal threshold, you must report the status change to the CRA by the end of the month following the month it changed.6Canada Revenue Agency. Marital Status
You can update your status through the CRA’s My Account portal or by mailing Form RC65 (Marital Status Change).6Canada Revenue Agency. Marital Status The change affects your tax filing, GST/HST credit, Canada Child Benefit, and other income-tested benefits, which the CRA recalculates based on combined household income. Failing to update your status can lead to the CRA clawing back overpaid benefits once the discrepancy surfaces.
The practical consequence of the two timelines running independently: you can owe tax obligations as a common-law couple a full year before you gain any property rights under BC law.
Opting Out With a Cohabitation Agreement
If the default equal-split rules do not fit your situation, you can contract around them. Section 81 opens with “subject to an agreement or order that provides otherwise,” which means a properly drafted cohabitation agreement can override the standard property division.2British Columbia Laws. British Columbia Code – Family Law Act – Property Division You can sign one before moving in together or at any point during the relationship.
To hold up if challenged, an agreement needs to meet several standards. Both partners should get independent legal advice from separate lawyers so neither can later say they did not understand what they signed. Both partners need to make full financial disclosure before signing; hiding assets or debts undermines the entire agreement. And the terms need to be substantially fair at the time of signing. An agreement that leaves one partner with nothing after a decade of shared life is vulnerable to being set aside by a court.
Ending the Relationship
Common-law couples in BC do not need a divorce. The relationship ends when one or both of you decide it is over and act on that decision. There is no court process required to end the status itself.
What does require either a court process or a written agreement is dividing property and debt, and the deadline is strict: two years from the date of separation to start a property or pension division claim, or to apply for spousal support.7British Columbia Laws. British Columbia Code – Family Law Act Formal mediation or another family dispute resolution process pauses that clock. Informal negotiations between partners do not. If you both agree on how to divide things, a properly signed separation agreement is as enforceable as a court order, and both partners should get independent legal advice before signing.
