Separation and joint bank accounts in Canada: who can take the money, who owes the debt, and what to tell the CRA
When a relationship ends, the shared accounts are often the first thing that goes wrong: one person empties the joint account, a card keeps growing a balance both people owe, or a pre-authorized debit keeps pulling from an account nobody watches. Banking rules do not decide who gets what in a separation; family law does. But they decide what can happen to the money this week. Here is what the federal rules say, a calculator for your shared debt, and a step-by-step list.

Joint debt and CRA date calculator
What could you be on the hook for, and when do you tell the CRA?
Based on FCAC: joint account holders may all be held responsible for debts such as overdraft; co-borrowers on a joint credit card are equally responsible for the balance; the primary cardholder is responsible for purchases by additional cardholders or authorized users. Who ends up paying between the two of you is a family law question. Day 90 is counted from the first day apart; check your exact date with the CRA.
Who can use a joint account
FCAC describes a joint account as one that lets two or more people make withdrawals, deposits, payments and other transactions. In practice that means either of you can usually move money out without the other's signature, unless your account agreement says otherwise. There is no federal rule that splits a joint balance 50/50 when a couple separates.
A Government of Canada guide on joint accounts adds a warning that applies here: money in a joint account could be claimed in a separation or divorce settlement. So taking the whole balance does not make it yours; it can come up again when property is divided. Our joint bank account guide covers the everyday rules and CDIC coverage.
Who owes joint debt
| Product | Who is responsible | FCAC rule |
|---|---|---|
| Joint account overdraft | All account holders may be | "You're also responsible for any transaction made by the other account holder" |
| Joint credit card (co-borrowers) | Each co-borrower, for the whole balance | Co-borrowers are equally responsible for the balance |
| Additional cardholder or authorized user | The primary cardholder only | The primary cardholder pays for those purchases |
| Guaranteed card | The guarantor and the borrower | A guarantor has no access but is responsible for the balance |
| Joint loan, line of credit or mortgage | Each joint borrower | Each becomes equally responsible for the unpaid balance |
"Equally responsible" does not mean half each. The lender can ask either of you for the full amount, and a missed payment can show up on both of your credit files. If your ex is an authorized user on your card, you can remove them at any time as primary cardholder, and you should, because you pay for what they charge. If you are the authorized user on theirs, you are not responsible for that balance.
Removing a name or closing the account
Banks set their own process, and the Government of Canada joint account guide notes that the bank may require both people named on the account to approve removing one of them. Banks must give you key information about their joint account policies when you open or convert an account, so ask for it again now. Ways people handle it:
- Open an account in your own name first and move your pay deposit to it.
- Ask the bank, in writing, how it handles a dispute between joint holders and what it needs to remove a name or close the account.
- Move pre-authorized debits one by one, so bills do not bounce. Our PAD cancellation guide has the FCAC steps.
- Close the joint account only once the balance is settled and nothing is still drawing on it; see how to close a bank account.
- Pay down or close joint credit, or ask the lender whether one person can take it over. The lender decides; it is not automatic.
Telling the CRA: the 90-day rule
The CRA says you must report a new marital status by the end of the following month after it changes. For a separation, you only count as separated once you have lived apart for more than 90 days because of a breakdown in the relationship. Once you reach that point, the effective date of your separated status is the day you started living apart.
- Update it in CRA My Account (immediate), by phone, on Form RC65 by mail (4 to 6 weeks), or on your tax return.
- Benefits and credits such as the Canada Child Benefit and the GST/HST credit are based on adjusted family net income, so the CRA recalculates them. Any adjustment starts the month after your status changed, and if you were overpaid you get a notice to repay.
- The CRA does not pass your new status to other government departments; update each one yourself.
Payment dates for the main benefits are in our 2026 benefit payment dates guide.
Worked example
Dev and Sara started living apart on September 1, 2026. They share a chequing account with $6,000 in it and $800 of overdraft from last month, a joint credit card with $4,200 owing, and Sara is an authorized user on Dev's own card, which carries $1,500.
| Item | Who the lender can ask | Amount |
|---|---|---|
| Joint overdraft | Dev or Sara | $800 |
| Joint credit card | Dev or Sara, full balance | $4,200 |
| Dev's card with Sara as authorized user | Dev only | $1,500 |
| Dev's possible exposure | $800 + $4,200 + $1,500 | $6,500 |
| Sara's possible exposure | $800 + $4,200 | $5,000 |
Either of them could also withdraw the $6,000 today. Day 90 apart falls on November 30, 2026; after that they report the change to the CRA, with September 1 as the effective date. Who repays what between them is for their separation agreement, but the lenders are not bound by it.
TFSAs, RRSPs and other accounts
A TFSA or RRSP is never joint, but separation still affects them. A TFSA can be split by a direct transfer under a written separation agreement or court order without using the receiver's room; see our TFSA rules for couples. If one of you contributed to a spousal RRSP, ask a tax professional how the three-year attribution rule applies once you live apart. Also check beneficiary and successor holder designations on every registered account, and joint safety deposit boxes and investment accounts at each institution.
First-week checklist
- List every joint account, card, line of credit and loan, with balances and both names.
- Open an account in your own name and redirect your pay.
- Remove your ex as an authorized user on any card where you are the primary cardholder.
- Ask each lender in writing about joint debt and what it needs to remove a name.
- Move pre-authorized debits and bill payments to your own account.
- Pull both credit reports for free to see every joint account; our Equifax vs TransUnion guide shows how.
- Mark day 90 on your calendar and update the CRA after it.
Options people compare
| Option | What it does | Watch for |
|---|---|---|
| Leave the joint account open for now | Keeps shared bills running | Either person can still withdraw |
| Split the balance by agreement | Each moves an agreed amount out | Put the agreement in writing |
| Close it once bills are moved | Ends shared liability for new overdraft | The bank may need both of you |
| Pay off and close joint cards | Stops new shared debt | The balance stays owed until paid |

Questions people ask
Can my ex empty our joint bank account?
Usually yes. FCAC says a joint account lets each holder make withdrawals and other transactions. Taking the money does not settle who owns it; a Government of Canada guide notes joint funds could be claimed in a separation or divorce settlement.
Am I responsible for my ex's overdraft on our joint account?
You may be. FCAC says joint account holders are responsible for transactions made by the other holder, and all holders may be held responsible for repaying overdraft debt.
Who pays a joint credit card after a separation?
Each co-borrower is equally responsible for the whole balance, so the issuer can ask either of you. How you split it between yourselves is for your separation agreement.
Can I remove my name from a joint account?
Ask your bank. Policies differ, and a Government of Canada guide notes the bank may require both people named on the account to approve removing one of them.
When do I tell the CRA I am separated?
Once you have lived apart for more than 90 days because of a breakdown in the relationship. Report it by the end of the following month, in My Account, by phone or on Form RC65. The effective date is the day you started living apart.
Will separating change my Canada Child Benefit or GST/HST credit?
It can. These are based on adjusted family net income, so the CRA recalculates them when your marital status changes, starting the month after the change.
Am I responsible for my ex's charges if they are an authorized user on my card?
Yes. FCAC says the primary cardholder is responsible for purchases made by additional cardholders or authorized users, and you can remove them at any time.
