What does a real estate lawyer actually do in a purchase closing?

Summary: In a purchase closing, your real estate lawyer reviews your Agreement of Purchase and Sale, searches title, coordinates with your lender, prepares the closing documents, calculates the adjustments, moves the funds through their trust account, pays the land transfer tax, and registers the transfer so the home is legally yours.

Buying a home involves a lot of paperwork, tight timelines, and large sums of money, and the legal side is where a real estate lawyer takes over. Here is what your lawyer actually does at each stage of a purchase closing in Ontario.

What does your lawyer review before closing?

Well before closing day, your lawyer reviews your Agreement of Purchase and Sale to confirm the conditions, dates, and any special terms. They then search the property's title to confirm you will receive clear ownership, free of liens, unpaid debts, or registered interests that could affect you, and they can arrange title insurance to cover issues that cannot be found before closing.

How does your lawyer work with your lender?

If you are taking out a mortgage, your lawyer works directly with your bank or lender. They receive and review the mortgage instructions, prepare and register the mortgage against title, and confirm the lender will advance the funds in time for closing. This is the step that connects your financing to the legal transfer, and it has to line up to the day.

What does your lawyer prepare for closing day?

Your lawyer prepares and reviews the documents that actually move ownership, so you do not have to manage them yourself. These typically include:

• The transfer (deed). The document that conveys ownership of the property into your name.

• Mortgage registration. Registering your lender's charge against the title.

• The statement of adjustments. A closing statement that prorates shared costs.

They also calculate the adjustments, such as property taxes or condo fees the seller has prepaid, so you only reimburse the portion that applies after your closing date.

How does your lawyer handle the money on closing day?

On closing day, the funds move through your lawyer's trust account in a set order. Your lawyer:

1. Receives the funds. Your down payment and the mortgage advance from your lender come into the lawyer's trust account.

2. Pays the seller. Your lawyer transfers the purchase funds to the seller's lawyer and confirms receipt.

3. Pays the land transfer tax and registers the transfer. Your lawyer remits the land transfer tax and registers the transfer and mortgage, at which point you officially own the home.

How does your lawyer protect you through the process?

Beyond the mechanics, your lawyer is the person who explains what you are signing, answers your questions in plain language, and flags problems early, before they become closing-day emergencies. Their role is to protect your interests at the one stage of the purchase where a mistake is hardest to undo.

Frequently asked questions

Do you need a lawyer to close a home purchase in Ontario?

In practice, yes. Reviewing title, registering the transfer and mortgage, and remitting land transfer tax are steps handled by a lawyer. Your real estate agent cannot complete the legal closing.

When does the real estate lawyer get involved?

Ideally as soon as your offer is firm. Your lawyer reviews the Agreement of Purchase and Sale, starts the title search, and coordinates with your lender in the weeks before closing, not just on closing day.

What does the lawyer do with the money?

Your down payment and the mortgage advance flow through the lawyer's trust account. The lawyer sends the purchase funds to the seller's lawyer, pays the land transfer tax, and registers the transfer, accounting for every dollar.

What are adjustments on a purchase closing?

Adjustments reconcile costs the seller prepaid, such as property taxes or condo fees, so you reimburse only the share that applies from your closing date forward. They appear on the statement of adjustments.

How long does a purchase closing take?

The legal work usually runs over the few weeks between a firm deal and the closing date, with the transfer and funds completed on closing day itself. Timelines vary with the lender and the deal.
