Common Law in BC: Duration, Rights & Proof Requirements

Few things in Canadian life are as quietly consequential as moving in with a partner, and in British Columbia, that decision can shift your legal status and rights after two years of cohabitation. Understanding what common-law means in BC is essential for protecting your finances, property, and family, whether planning to live together or already doing so.

Minimum cohabitation for common-law spouse in BC: 2 years ·
Minimum cohabitation for Canada Pension Plan survivor benefits: 1 year ·
Number of BC Family Law Act statutes defining common-law spouse: 1

Five key facts, one pattern: BC law treats common-law relationships almost like marriage for support and property, but only after meeting specific cohabitation thresholds — and the clock counts differently depending on which law you’re looking at.

How long do you have to live together for common-law in BC?

What is the exact cohabitation period?

• Under the Family Law Act, a common-law spouse requires living together in a marriage-like relationship for at least two years, according to Legal Aid BC (BC’s primary legal aid provider).
• For Canada Pension Plan survivor benefits, the required period is one year, per the Government of Canada (federal benefits authority).
• Couples with a child together may be considered common-law spouses without the full two-year period if they have lived in a marriage-like relationship for less than two years, Legal Aid BC explains.

Does the period apply to all couples?

• Yes, the two-year rule applies regardless of gender, Legal Aid BC confirms — same-sex and opposite-sex couples are treated identically under BC family law.
• If you already have a child together, BC law may recognize you as common-law spouses even before the two-year mark, the YLaw family law firm notes.

The implication: the two-year rule is the default, but having a child together can accelerate recognition. For couples without children, the clock starts fresh from the day you begin living together in a conjugal relationship.

What exactly is common-law in BC?

Definition of common-law relationship

• A common-law relationship is an unmarried couple living together in a conjugal relationship, as DSG Family Law (BC law specialists) describes.
• The BC Family Law Act defines “spouse” to include common-law partners who meet the requirements, YLaw explains.
• A marriage-like relationship typically includes shared finances, cohabitation, and emotional commitment, DSG Family Law adds.

Criteria for a marriage-like relationship

• There is no fixed checklist; courts look at the overall picture, according to DSG Family Law.
• Key indicators include living together, sharing household expenses, presenting yourselves as a couple publicly, and having an emotional bond, Family Law in BC (BC government-funded legal resource) notes.

The pattern: BC law uses a flexible, fact-based test rather than a rigid legal category. The trade-off is clarity — borderline cases can be unpredictable, which is why documentation matters.

How does common-law work in BC?

Rights and responsibilities

• Common-law spouses have similar rights to married spouses regarding spousal support and property division after separation, per Legal Aid BC.
• They must file taxes as common-law partners after one year of cohabitation, the Canada Revenue Agency (federal tax authority) requires.
• Common-law status does not automatically grant inheritance rights without a will, Legal Aid BC cautions.

How common-law differs from marriage

• No formal ceremony is required for common-law status, DSG Family Law notes.
• Married spouses must apply to BC Supreme Court for a divorce order; there is no automatic divorce after separation, Legal Aid BC explains.
• Common-law partners have no automatic right to a division of property unless they meet the two-year cohabitation rule, Family Law in BC warns.

Five differences, one pattern: common-law and marriage converge on support obligations but diverge on property rights and inheritance — and common-law status can end without any court paperwork.

The trade-off: common-law offers flexibility with no ceremony, but the same flexibility means fewer automatic protections. For inheritance protection, a will is essential for common-law partners in BC.

How do I prove a common-law relationship in BC?

Documents and evidence

• Proof requires evidence of continuous cohabitation for the required period, Family Law in BC states.
• For immigration purposes, Immigration, Refugees and Citizenship Canada (federal immigration authority) accepts shared ownership of property, joint leases, shared utility bills, and documents showing the same address.
• YLaw says a marriage-like relationship can be proven with evidence such as tax returns, pictures, texts, bills, rental contracts, and caregiving during illness, per YLaw (BC family law firm).

Steps to prove common-law relationship

1. Live together in a marriage-like relationship for at least two years (one year for federal purposes like CPP and taxes).
2. Gather evidence of shared residence, finances, and daily life (joint leases, utility bills, bank accounts, tax returns showing common-law filing).
3. Obtain affidavits from friends, family, or colleagues attesting to the marriage-like nature of the relationship.
4. Declare common-law status on tax returns after one year of cohabitation, as required by the CRA.
5. If applying for immigration, submit the required IRCC forms along with evidence such as shared property ownership, joint leases, and utility bills.

Legal procedures for proving status

• Government forms (e.g., for tax or immigration) may ask for a declaration of common-law status, the CRA explains.
• IRCC says applicants do not need to include every listed item to prove a common-law relationship, IRCC guidance notes.
• Photos, telephone bills, and letters submitted as proof are not returned, IRCC adds.

What is a common-law spouse entitled to in BC?

Property division after separation

• Common-law spouses may be entitled to spousal support and property division if they meet the criteria under the Family Law Act, Legal Aid BC explains.
• Only couples who have lived together for at least two years have the right to divide property and debt, Family Law in BC clarifies.
• If married people separate and one enters a new common-law relationship for at least two years, that person can be considered an unmarried spouse of the new partner even if still legally married, Legal Aid BC notes.

Spousal support eligibility

• Spousal support is available to common-law partners who meet the relationship criteria, regardless of whether they also qualify for property division, Legal Aid BC states.
• The same federal Spousal Support Advisory Guidelines apply to both married and common-law spouses, Family Law in BC confirms.

Tax and benefit implications

• Common-law partners must file taxes as a couple after one year of cohabitation, per the Canada Revenue Agency (federal tax authority).
• Benefits like the Canada Child Benefit (CCB) are calculated based on combined household income once you are common-law, the CRA explains.
• Entitlements vary depending on the length of the relationship and whether a child is involved, Family Law in BC notes.

What this means: a common-law partner in BC has strong claims to spousal support and — after two years — property division. But inheritance, tax benefits, and child-related credits all have separate rules that can catch couples off guard.

“A common-law relationship is an unmarried couple living together in a conjugal relationship. Under BC family law, common-law couples can have the same rights and responsibilities as married couples for certain family-law issues.”

Legal Aid BC (BC’s primary legal aid provider)

“For immigration purposes, shared ownership of property, joint leases, shared utility bills, and documents showing the same address are accepted as evidence of a common-law relationship.”

Immigration, Refugees and Citizenship Canada (federal immigration authority)

For a BC resident navigating common-law status, the choice is clear: document your relationship from day one, understand that two years is the key milestone for provincial rights (one year for federal purposes), and get a will if you want inheritance protection. Your partner’s rights after separation depend on what you do now, not later.
