Common Law Partner Debt in BC and Who Has to Pay It
By SiLaw Group Family LawyersPublished Nov 13, 2026 · 6 min read
If you lived in a marriage-like relationship for at least two years, debt either of you took on during the relationship is family debt under section 86 of the Family Law Act, and on separation each of you is equally responsible for it, whichever name is on the account.
That rule surprises people more than the property rule does. SiLaw Group Family Lawyers sees it most often with credit cards, lines of credit and vehicle loans that one partner ran up and the other never knew the size of. Our common law property rights page covers the property side of the same regime, and our family debt page covers the service.
What Counts as Family Debt Under the Family Law Act?
Section 86 of the Family Law Act defines family debt as all financial obligations incurred by a spouse during the period beginning when the relationship between the spouses begins and ending when the spouses separate, and, after the date of separation, obligations incurred for the purpose of maintaining family property. The definition turns on timing and purpose, not on whose name is on the paperwork and not on what the money was spent on.
Both ends of that period are facts to be proven. The relationship begins, under section 3(3) of the Family Law Act, on the date the couple began living together in a marriage-like relationship. It ends at separation, which under section 3(4) of the Act can happen while you still share a home. A credit line opened a month before you moved in is outside the window. One opened a month after you separated is outside it too, unless it paid for the mortgage or repairs on the family home.
Who Pays Family Debt When Common Law Partners Separate?
Both of you, equally, as a starting point. Section 81 of the Family Law Act provides that spouses are both entitled to family property and responsible for family debt regardless of their respective use or contribution, and that on separation each spouse is equally responsible for family debt. That is subject to an agreement or order that provides otherwise, and to the Act's exceptions, but the default is a 50/50 split of the family debt alongside the 50/50 split of family property.
Does the Bank Care Who the Family Law Act Says Should Pay?
No. Section 82 of the Family Law Act says nothing in Part 5 affects the rights and remedies of a spouse's creditors, guarantors or assignees in relation to family debt. The lender's contract is with whoever signed it. If the car loan is in your name and the Act makes your former partner responsible for half, the bank still collects from you, and your remedy is against your partner.
The Act gives the court tools for that. Under section 97(2)(h) of the Family Law Act, the Supreme Court of British Columbia may declare that one spouse is responsible for payment of an item of family debt and must indemnify the other spouse for it, and under section 97(2)(i) of the Act it may order the sale of property to pay a debt. Section 97(3) confirms that an order about family debt applies only as between the spouses and does not affect an agreement between a spouse and anyone else. Refinancing, paying out and closing joint accounts, where possible, is therefore part of nearly every settlement. Our guide to separating your finances walks through the practical steps.
Can Family Debt Be Divided Unequally?
Yes, in two ways. The first is by agreement. Section 92(a) of the Family Law Act allows spouses to agree to divide family debt equally or unequally, and section 92(b) and (c) of the Act allow them to include or exclude specific debts. A cohabitation agreement can set debt rules in advance, and a separation agreement can set them afterwards.
The second is by court order. Under section 95(1) of the Family Law Act, the Supreme Court of British Columbia may order an unequal division of family debt, or family property, or both, if equal division would be significantly unfair. Among the factors in section 95(2) of the Act, three speak directly to debt: whether the family debt was incurred in the normal course of the relationship, the ability of each spouse to pay a share of the family debt if the debt exceeds the value of the family property, and whether a spouse after separation caused a significant increase in family debt beyond market trends. Gambling losses, secret spending or debt run up after separation are the kinds of facts that get argued under those factors, and the threshold is significantly unfair, not merely unfair. Our unequal division page explains how high that bar sits.
What Debt Is Not Shared?
Debt from before the relationship began is not family debt under section 86 of the Family Law Act, because it was not incurred during the period the section describes. Student loans, consumer debt and tax owing from before you moved in together stay with the person who owed them. Debt incurred after separation is not family debt either, unless it was taken on to maintain family property.
The other exception is the two-year threshold itself. Part 5 of the Family Law Act applies to spouses, and for property and debt purposes section 3(1)(b)(i) of the Act requires a continuous period of at least two years in a marriage-like relationship. A couple who separate at eighteen months do not share family debt under the Act. Each is bound by the contracts they signed and no more. Our two-year rule page covers the threshold.
When Is Family Debt Valued?
Under section 87 of the Family Law Act, unless an agreement or order provides otherwise, the value of family debt is determined as of the date an agreement dividing it is made or the date of the court hearing, not the date of separation. A balance paid down or allowed to grow since separation is counted at the later date, which is one reason post-separation conduct appears in the section 95 factors.
Does the Two-Year Deadline Apply to Debt Claims?
Yes. Section 198(2)(b) of the Family Law Act requires a spouse who lived in a marriage-like relationship to start a proceeding to divide property or family debt no later than two years after the date of separation. A partner who wants the other to share a debt, and a partner who wants an unequal division in their favour, are both on the same clock. Our property claim deadlines tool gives an approximate date.
Frequently Asked Questions
Am I Responsible for My Common Law Partner's Credit Card Debt?
If you were spouses under the Family Law Act and the debt was incurred during the relationship, it is family debt under section 86 of the Act and you are equally responsible for it between the two of you under section 81, whichever name is on the card. The card issuer can still only pursue the cardholder. Whether an unequal division is available depends on the section 95 factors.
What If My Partner Ran Up Debt I Knew Nothing About?
It is still family debt if it was incurred during the relationship. Whether it was incurred in the normal course of the relationship is one of the factors in section 95(2) of the Family Law Act for an unequal division, so gather the statements and get advice.
We Were Together Under Two Years. Do We Share Debt?
Not under the Family Law Act. Part 5 of the Act, including the family debt rules, applies only to spouses, and for that purpose you need a continuous two years of living together in a marriage-like relationship. Each of you is responsible for the debts you signed for. Joint accounts remain joint under the lender's contract.
