Many separating spouses in Ontario assume that once they move out or begin living separate lives, their legal and property rights automatically change. Unfortunately, that is not always true.
One of the most misunderstood issues in Ontario family and estate law is what happens to a jointly owned home when one separated spouse dies before a separation agreement is signed or property ownership is formally changed.
In many cases, the surviving spouse may automatically become the sole owner of the property, even if the parties were separated for years.
Joint Tenancy and the Right of Survivorship
Most married couples in Ontario purchase their home as joint tenants.
When property is owned as joint tenants, each owner holds an equal interest in the entire property. The most important feature of joint tenancy is the right of survivorship.
This means that when one owner dies:
- their interest does not pass through their estate,
- it does not go according to their will, and
- it automatically transfers to the surviving joint owner.
As a result, if separated spouses still hold title as joint tenants when one spouse dies, the surviving spouse may become the sole legal owner of the property automatically.
Does Separation Automatically End Joint Tenancy?
No.
Under Ontario law, separation alone does not automatically sever a joint tenancy.
Even where spouses:
- live separately,
- begin dividing finances,
- start discussing separation terms, or
- intend to divorce,
the right of survivorship may still remain in place unless the joint tenancy is legally severed.
This often surprises families and estate beneficiaries who expected the deceased spouse’s share of the home to pass through the estate.
How Is a Joint Tenancy Severed?
A joint tenancy may be severed in several ways, including:
- A Written Agreement
A properly drafted separation agreement may clearly state that the parties intend to sever the joint tenancy and hold the property as tenants in common instead.
- Registration on Title
One spouse may register documents on title converting ownership into tenants in common.
- Conduct Showing Mutual Intent
Ontario courts may find severance occurred where the parties’ actions clearly demonstrate an intention to treat their ownership interests separately.
Examples may include:
- formal property division negotiations,
- court proceedings,
- equalization claims,
- agreements to sell the property and divide proceeds, or
- other evidence showing survivorship was no longer intended.
What Happens if the Joint Tenancy Was Severed?
If severance occurred before death:
- the deceased spouse’s share forms part of their estate,
- the share passes according to the will (or intestacy laws if there is no will), and
- the surviving spouse does not automatically inherit the entire property.
Instead, the parties become tenants in common, each owning a separate divisible interest.
Important Ontario Case Law
The leading Ontario Court of Appeal decision on severance of joint tenancy is:
- Hansen Estate v. Hansen
In that case, the Court confirmed that severance can occur through mutual agreement or conduct demonstrating a shared intention to end the joint tenancy relationship.
Why This Matters
Failure to properly document separation terms can create significant disputes between:
- surviving spouses,
- children from prior relationships,
- estate trustees, and
- beneficiaries.
We frequently see situations where:
- one spouse believed their share would pass to their children,
- but title remained in joint tenancy,
- resulting in the surviving spouse automatically receiving full ownership.
These disputes often lead to expensive estate litigation.
Protecting Yourself During Separation
If you are separating in Ontario, it is critical to properly address:
- ownership of the matrimonial home,
- joint tenancy versus tenancy in common,
- survivorship rights,
- wills and powers of attorney,
- beneficiary designations, and
- estate planning implications.
Simply separating is not enough.
