A Line of Credit Secured Against the Home After Separation in Ontario

A home equity line of credit is convenient right up until the marriage that took it out ends. A line of credit secured against the home after separation raises two separate problems most couples haven't thought through: how the outstanding balance affects the home's value for equalization, and the very real risk that one spouse can keep drawing on a shared line of credit while the other has no idea it's happening.

Because the matrimonial home carries special rules under Ontario's Family Law Act, a HELOC secured against it deserves closer attention than an ordinary debt.

How a HELOC Affects the Home's Net Value

For equalization purposes, what matters isn't the home's gross market value — it's the net equity, meaning the home's value minus whatever is owed against it, including any mortgage and any home equity line of credit. A larger HELOC balance on the date of separation means less net equity attributed to the home in the overall calculation, the same way a larger mortgage balance would.

This sounds straightforward until you remember that a HELOC balance can change quickly — unlike a mortgage with a fixed amortization schedule, a line of credit can be drawn on, paid down, and redrawn, sometimes right up until (or after) the date of separation.

The Matrimonial Home's Special Rules Apply to the Debt Too

The Family Law Act treats the matrimonial home differently from other property: both spouses have an equal right to possess it regardless of whose name is on title, and neither spouse can sell, mortgage, or otherwise encumber it without the other's consent, a release in a separation agreement, or a court order — even if only one spouse holds legal title.

That consent requirement matters directly for a HELOC. If the home is titled to one spouse only, that spouse still generally cannot draw further against a line of credit secured on the matrimonial home, or take out a new one, without the other spouse's consent. This is one of the more important — and more commonly misunderstood — protections built into Ontario family law specifically for the home you live in.

The Risk: One Spouse Continuing to Draw on a Joint Line of Credit

Where the HELOC is a joint account, both spouses are typically named borrowers and both remain fully liable for the balance to the lender — regardless of who's actually using it after separation. This creates a specific and genuinely serious risk: a spouse who still has online or in-branch access to a joint line of credit can, practically speaking, continue to draw funds after separation, increasing a debt that both of you remain liable for even though only one of you benefited from the money.

What You Can Do to Protect Yourself

• Contact the lender promptly after separation to understand your specific line of credit's terms and whether a freeze, hold, or joint-authorization requirement can be put in place
• Ask for current statements and, if possible, transaction-level detail showing any draws close to or after your date of separation
• Raise the issue with your lawyer immediately if you're concerned about ongoing access — this is a time-sensitive practical problem, not just a paperwork detail to sort out later
• Make sure any separation agreement specifically addresses the HELOC balance as of the date of separation, and who is responsible for balance changes after that date

How the Balance Gets Divided

The HELOC balance as of the date of separation is generally netted against the home's value in the equalization calculation, the same as a mortgage. Draws made after separation are a different question — they raise an argument that the draws (and their associated debt) shouldn't be attributed to the home's value for equalization purposes at all, since they happened outside the marriage. Whether and how that argument succeeds depends heavily on the specific facts, including whether both spouses had a genuine ability to prevent further draws.

This is exactly the kind of situation where documenting the timeline — statements from around the date of separation, records of any draws afterward, and communication about the account — makes a real difference to the outcome.
