Key takeaways
  • Whether an existing title insurance policy covers a new owner depends on the policy wording, so check with the insurer and your lawyer before relying on it.
  • Adding someone to title still requires a registered transfer made through an authorized user such as a lawyer.
  • Land transfer tax can apply when someone is added, for example if they assume part of a mortgage.
  • How you hold title, joint tenants or tenants in common, changes what happens on death.

You own your home and want to add a spouse, partner or adult child to the title. You remember buying title insurance when you purchased and wonder whether it still protects everyone, or whether you must buy a new policy.

There is no one-line answer, because it turns on the wording of your own policy. This article explains what to ask, what else changes when title changes, and how to get the right advice before you sign.

What title insurance generally does

Title insurance is a policy you may have bought when you purchased your home. What it covers, and who is insured under it, depends on the wording of your own policy.

Because it protects named insureds and the policy has its own terms and exclusions, adding a new owner raises a fair question: is the new person an insured, or only the original owner? The answer is in your policy documents, and your insurer can confirm it in writing.

The question to ask your insurer

Whether your insurer needs to be told about a family transfer, and what it will do about coverage, depends on the insurer and your policy. Practices differ between insurers and policies, and a general article cannot tell you which applies to yours. Ask the insurer directly and keep the reply.

Your lawyer will also be able to review the policy and tell you whether the family transfer affects it.

Adding a name is a registered transfer

Adding an owner is not just a paperwork update. It requires a transfer that changes who is on title. Only authorized Teraview account holders and their registered users can create and submit documents in Ontario's electronic land registration system, and authorized groups include lawyers, conveyancers and financial institutions. Registrations are entered by authorized users and then reviewed and certified by ServiceOntario.

If you have a mortgage, your lender's terms may also matter, since a change in ownership could require the lender's consent. Check your mortgage documents or ask the lender before you transfer.

Other issues that come up when you add someone

IssueWhat to know
Land transfer taxAssumed mortgage debt is consideration. A gift with no consideration in any form attracts no tax, reported as nil
RelationshipAn encumbrance is taxed as consideration regardless of the relationship, except certain spousal transfers under Regulation 696
Type of ownershipJoint tenancy has a right of survivorship; tenancy in common does not
Changing between formsSwitching between tenancy in common and joint tenancy between the same parties is not a conveyance
Forced saleJoint tenants have a prima facie right to force a sale under the Partition Act

The last row matters for parents adding a child. Once someone is on title, they have their own legal rights in the property. If the relationship later breaks down, the home can become the subject of a dispute. Adding a name is often easy to do and hard to undo, so think about creditors, a child's marriage breakdown and your own estate plan.

What to do next

A lawyer can coordinate the transfer, the tax reporting and the insurance question so nothing is missed.

Frequently asked questions

Does my old policy automatically cover the new owner?

It depends on the policy wording. Some policies extend to certain transfers and others do not. Ask your insurer for written confirmation and have your lawyer review it.

Can I add a name myself?

Documents are created and submitted through the electronic system only by authorized Teraview account holders and their registered users, such as lawyers. How this applies to your situation is worth confirming with a lawyer.

Will adding my child trigger land transfer tax?

If no consideration passes in any form, no tax is payable and the transfer is reported as nil. If the child assumes a mortgage, that assumed debt is consideration. A lawyer can assess your facts.

Should I choose joint tenancy or tenancy in common?

Joint tenancy includes a right of survivorship, while a tenancy in common interest falls into the deceased's estate. The right choice depends on your family and estate plans, so get advice.
