Joint debt at separation: who pays what, and why the bank doesn't care about your agreement

Assets get the attention. Debt does the damage. Couples spend weeks negotiating the house and then agree in a sentence that "each party will pay the debts in their own name," without checking whose name is on what, or what happens when one of them doesn't pay. Eighteen months later a collection call arrives about a card the other person was supposed to clear. This guide is about not being that person.

How debt is divided

In most Canadian provinces, debts incurred during the relationship are family debts regardless of whose name is on them, and they are shared in the same way as assets. Ontario's equalization model deducts each spouse's debts from their assets to arrive at net family property, so debt reduces the value being shared. BC's Family Law Act explicitly defines family debt and divides it equally unless that would be significantly unfair.

In US community property states, debts incurred during marriage are generally community debts, shared equally. In equitable distribution states they are marital debts, divided fairly. In both, debt incurred for one spouse's separate benefit, such as gambling or an affair, may be assigned to that spouse.

Debt incurred after the separation date is usually the responsibility of the person who incurred it. This is another reason the separation date matters.

The limit of your agreement

Your separation agreement is a contract between you and your former partner. It is not a contract with the bank. If a joint line of credit is assigned to your ex in the agreement and they stop paying, the lender is entitled to collect from you, report the missed payments on your credit file, and sue you. Your recourse is against your ex under the agreement, which is only useful if they have money and you are willing to go after it.

So the strategy is to reduce how much you depend on the agreement, and to make the agreement strong for whatever is left.

Step one: stop the bleeding

• Freeze joint credit. Call the issuer of every joint card and line of credit and ask to freeze new borrowing. Most lenders will do this on the request of one account holder, though closing usually needs both or a zero balance.
• Remove yourself as a supplementary cardholder on your ex's cards, and remove them from yours.
• Pull your credit report from Equifax and TransUnion (both operate in Canada and the US). Look for accounts you did not know existed.
• Open your own account and redirect your income before anything else.

Step two: separate what can be separated

The cleanest outcome is that each debt ends up in the name of the person responsible for it. Practically:

Credit cards

Pay off and close joint cards using joint funds or as part of the settlement. Where a balance remains, transfer it to a card in the responsible person's name.

Lines of credit

Refinance into the responsible person's name, or pay down from the sale of an asset. Home equity lines are tied to the house and are dealt with when the house is sold or refinanced.

Car loans

Whoever keeps the car should refinance the loan into their own name. If they cannot qualify, either sell the car or accept the risk with a strong indemnity and a right to repossess and sell if they default.

The mortgage

If one spouse keeps the house, the other must be released from the mortgage, which means the staying spouse refinances alone. Transferring title without refinancing leaves the departing spouse liable for a debt on a house they no longer own. Read what happens to the mortgage when you split.

Step three: make the agreement do the rest

For anything that cannot be separated, your agreement should include:

• A schedule of debts listing each one, the balance at the separation date, whose name it is in, and who is responsible.
• An indemnity: the responsible spouse agrees to pay and to compensate the other for any loss if they don't, including legal costs.
• A deadline to refinance or pay off each joint debt, with a consequence if missed, such as the other spouse's right to sell an asset or set the amount off against support.
• A disclosure warranty that neither spouse has undisclosed debts. If one turns up later, it belongs to the person who hid it.
• Security where the amount is large: a charge on property, or a holdback from the sale proceeds of the home until the debt is cleared.

Bankruptcy

If your ex declares bankruptcy, their obligation to you under the agreement to pay a joint debt may be discharged, but the lender's claim against you is not. Child and spousal support survive bankruptcy in both countries. Property equalization payments in Canada generally do not, which is why security matters for large amounts.

Your credit after separation

Your credit history is yours alone; there is no joint credit score. What links you is the joint accounts. Once those are closed or separated, your ex's behaviour stops affecting your file. Until then, monitor it. Set up alerts with the credit bureaus, and if a joint account you were assigned falls behind, pay it and pursue your ex rather than letting it damage your ability to get a mortgage.

Checklist

1. List every debt, balance, and whose name it is in.
2. Freeze joint borrowing and remove supplementary cardholders.
3. Pull both credit reports.
4. Decide who takes what, then refinance or pay off each joint debt.
5. Draft the schedule, indemnity, deadline and security into your agreement.
