Do I actually need a real estate lawyer in Ontario, and what do they do?

3 min read Updated September 2026 Written by Chetanaya Gupta, Ontario lawyer

The short version

Yes, in practice you need one. Registering a transfer of title in Ontario requires legal statements only a lawyer can make, lenders require a lawyer for the mortgage, and your lawyer checks title, handles your mortgage funds, and makes sure the deal closes properly, whether you're buying, selling, or refinancing.

01

Why do I legally need a lawyer at all?

Registering a transfer of title through Teraview, Ontario's electronic land registration system, requires compliance-with-law statements that only a lawyer licensed by the Law Society of Ontario can make, whether you're paying cash or using a mortgage. Mortgage lenders also require a lawyer to act on the mortgage. Under the Law Society's rules, buyer and seller generally need separate lawyers, with only narrow exceptions.

02

What does a lawyer do for a buyer?

  • Title search: confirms the seller actually owns the property and checks for liens, easements, or old undischarged mortgages registered against it.
  • Mortgage instructions: follows your lender's requirements exactly before releasing funds.
  • Tax and utility certificates: confirms property taxes and utilities are paid up, so you don't inherit the seller's debts.
  • Statement of adjustments: the final accounting of who owes what, like prepaid property taxes.
  • Closing: wires funds, registers the transfer, and coordinates key release.
03

What does a lawyer do for a seller?

Requests a mortgage payout statement from your lender, prepares the deed and closing documents, clears anything registered against the property that needs to be discharged, and sends you the balance of your proceeds once registration is confirmed. See our selling a home page for more detail.

04

When should I call a lawyer, before or after I sign?

Before, if you can. A lawyer can flag a problem clause or a condition deadline before it costs you something. If you've already signed, call right away rather than waiting, especially if a financing or inspection condition is still running. Most of a lawyer's work happens in the two to three weeks before closing, so waiting until closing week limits what can be caught or fixed.

05

What does a lawyer do that a real estate agent doesn't?

Your agent negotiates the deal and helps with the offer. Your lawyer reviews the legal terms, checks title, handles your money, and registers the transaction. They work together but do different jobs. An agent can't give legal advice on your agreement's wording, and a lawyer generally doesn't get involved in negotiating price.

What to do next

Where to go from here

  1. Contact a lawyer as soon as your offer is signed or firm, not the week of closing.
  2. Send the complete signed agreement, including all schedules, not a summary.
  3. Ask your lender to send mortgage instructions directly to your lawyer's office.
Quick questions

People also ask

Can I use the same lawyer as the person I'm buying from or selling to?

No. Law Society of Ontario rules generally require separate lawyers for each side of a residential transaction.

Do I need a lawyer if there's no mortgage involved?

Yes. Title still needs checking and the deed still needs registering, mortgage or not.

How early should I hire a lawyer?

As soon as your offer is signed or firm. Most of the work happens in the final two to three weeks before closing.

Does my lawyer negotiate the purchase price?

No. That's your real estate agent's role. Your lawyer handles the legal and financial mechanics of the transaction.
