Enforcing a Small Claims Judgment Against a Joint Bank Account in Ontario

You have a judgment, you know exactly which bank the debtor uses, and then you find out the account is held jointly with a spouse, parent, or business partner who owes you nothing. Does that change anything? Garnishing a joint bank account in Ontario is legally possible, but it is far messier than garnishing an account held solely by the person who owes you.

Here is how the process generally works, and why joint accounts create a genuine complication.

How Garnishing a Bank Account Works

Garnishment lets a judgment creditor reach money someone else — typically a bank or an employer — owes to the debtor. For a Small Claims Court judgment, this generally starts with issuing a notice of garnishment; as of late 2025, the Small Claims Court fee for that step is $144, though figures change and should be verified before you rely on them. Once served, the garnishee (the bank, in this case) is generally required to hold or pay over money it owes the debtor, up to the amount of the judgment.

That works cleanly when the account belongs solely to the debtor. A joint account is a different situation.

The Problem With Joint Accounts

A judgment is only enforceable against the debtor named in it — not against anyone who happens to share a bank account with them. When a garnishment notice reaches a joint account, the bank and the other account holder both face a genuine question: how much of that money actually belongs to the debtor, versus the other holder?

In practice, this uncertainty tends to slow things down. A bank may freeze or hold the account temporarily while ownership is sorted out, rather than simply paying out the full balance. The result can be delay, partial recovery, or a dispute that has to be resolved before any money actually moves.

What the Non-Debtor Account Holder Can Do

Someone who holds a joint account with a judgment debtor, but who is not themselves liable on the judgment, generally has the ability to object to a garnishment and assert that some or all of the funds belong to them rather than the debtor. How that gets resolved depends on the facts — things like whose income funded the account, how it has historically been used, and what each party can show.

This is exactly the kind of dispute that can turn a simple garnishment into a contested, drawn-out process, which is worth planning for on both sides.

Practical Alternatives for Creditors

Because joint accounts invite disputes, creditors often have better luck with other approaches:

• Identifying an account held solely in the debtor's name, if one exists
• Garnishing wages directly, subject to the portion Ontario law protects from garnishment
• Using an examination in aid of execution to formally ask the debtor, under oath, about where their money and assets actually are
• Pursuing a writ of seizure and sale against property clearly owned by the debtor alone

A joint account is rarely the cleanest or fastest target, even when it is the most obvious one.

What to Do Before You Garnish

Before spending time and filing fees on a garnishment notice against an account you believe is joint, it is worth considering:

• Whether you have confirmed the account is genuinely joint, rather than assuming based on limited information
• Whether a solely-held account or wage garnishment might be a more direct route
• Whether the likely dispute over ownership is worth the delay, given the amount at stake
• Whether an examination of the debtor first would give you better information to act on
