What Does a Real Estate Lawyer Actually Do for Buyers and Sellers?

General
27 August, 2026

Short Answer

A real estate lawyer helps turn a signed Agreement of Purchase and Sale into a legally completed transfer. For a buyer, that generally means investigating title, coordinating mortgage funding, explaining closing documents, arranging the money required, registering the transfer and mortgage, and reporting after closing. For a seller, it generally means preparing the transfer documents, responding to title questions, arranging mortgage and other required payouts, receiving the purchase funds, completing the transfer, and accounting for the net sale proceeds.

The lawyer is also a risk manager. Problems such as an old mortgage on title, a writ against a party, inconsistent names, a tenancy issue, an unexpected adjustment, or incomplete lender instructions can interrupt an otherwise routine closing. The lawyer’s job is to identify legal issues, explain available options, and carry out the client’s lawful instructions—not to promise that every transaction will close without difficulty.

Detailed Answer

Why is a real estate lawyer needed in an Ontario closing?

A home purchase or sale is not completed merely because the parties sign an agreement or exchange money. Ownership must be transferred through Ontario’s electronic land-registration system, closing documents and funds must be exchanged under agreed procedures, and registered interests must be dealt with. Ontario restricts the electronic submission of land documents to authorized users; in practice, lawyers carry out the registrations for ordinary residential closings.

A lawyer also works within professional duties that do not belong to the real estate agent, lender, insurer, or home inspector. The Law Society of Ontario’s rules require a lawyer advising on a real estate conveyance to assess reasonable options for assuring title and to advise the client that title insurance is not a substitute for legal advice. That is one reason the lawyer’s role is broader than ordering a policy or uploading a deed.

The lawyer usually becomes the transaction’s legal coordinator. They communicate with the other side’s lawyer, the lender, title insurer, municipality or tax department where appropriate, and the client. However, each participant still has a separate function, and the lawyer does not automatically take over every practical or financial task connected with moving.

What does a real estate lawyer do for a buyer?

For a buyer, the central legal objective is to acquire the ownership interest promised in the agreement, subject only to permitted registrations and risks the buyer has knowingly accepted. The file usually moves through the following stages.

1. Reviews the agreement and transaction details

The Agreement of Purchase and Sale controls the transaction. The lawyer reviews the parties, property description, purchase price, deposit, closing date, conditions, included and excluded items, rental contracts, adjustments, and any schedules or amendments provided. The lawyer may identify wording that requires clarification or creates a legal or closing risk.

Timing matters. If the buyer signs an unconditional agreement before asking for legal advice, the lawyer may be able to explain a problem but not restore a condition or cancellation right that the contract does not contain. For builder purchases, assignments, private sales, and condominium transactions, early legal review is especially important because the documents can contain additional charges, occupancy terms, restrictions, or short review periods.

2. Searches title and reviews registered interests

A title search examines the registered ownership and instruments affecting the land. The lawyer checks whether the seller appears entitled to transfer the property and reviews registrations such as mortgages, easements, restrictions, notices, or liens that may affect the buyer’s interest.

Not every registration is a defect. An easement for utilities, for example, may properly remain on title. The legal question is whether the title delivered on closing complies with the agreement and whether any remaining interest creates a material concern for the buyer or lender. Depending on the property and instructions, off-title searches, municipal information, tax information, or other certificates may also be required.

3. Raises title questions and works toward solutions

If the search reveals an unexpected item, the buyer’s lawyer communicates with the seller’s lawyer within the agreement’s deadlines. The response might involve a discharge, correction, undertaking, holdback, title-insurance solution, amendment, or another arrangement appropriate to the facts.

This stage illustrates why a lawyer cannot guarantee a perfectly smooth closing. Some problems depend on third parties, older registrations, government records, lenders, or the other contracting party. The lawyer advises the buyer about the issue and the available legal options, then follows the buyer’s instructions.

4. Coordinates the mortgage and lender requirements

Where the buyer is financing the purchase, the lawyer also commonly acts for the institutional lender, subject to the professional rules and the lender’s instructions. The lawyer reviews the mortgage instructions, prepares or receives the mortgage documents, obtains signatures, satisfies stated funding conditions, registers the charge, and reports to the lender.

The approved mortgage amount is not always the same as the net amount delivered to the lawyer. Lender fees, holdbacks, interest adjustments, or unmet conditions can affect the advance. Buyers should therefore avoid assuming that a mortgage approval alone confirms the exact cash required on closing.

5. Explains documents and verifies identity

The lawyer or legal team arranges signing and identity verification using permitted procedures. Documents may include the transfer, mortgage, directions, declarations, tax or rebate forms, title-insurance materials, and the statement of adjustments. The lawyer explains the legal effect of the documents and answers transaction-specific questions before signatures are finalized.

Many Ontario residential closings can be handled remotely, depending on the lender, client, documents, and verification requirements. Khan Law’s established remote process may include secure information collection, identity verification, a video meeting, electronic signatures where accepted, and approved delivery of closing funds.

6. Calculates and receives the buyer’s closing funds

The buyer’s lawyer prepares or reviews the financial accounting for closing. The amount requested from the buyer can include the balance of the purchase price after the deposit and net mortgage advance, land transfer tax, legal fees and disbursements, title insurance, registration charges, adjustments, and property-specific amounts.

The statement of adjustments allocates items such as property taxes, condominium common expenses, fuel, or other prepaid amounts between buyer and seller as of closing. It does not replace the lawyer’s trust ledger, but it is an important part of determining the amount due between the parties.

7. Closes the transaction and registers ownership

On closing, the lawyers exchange documents, funds, and required confirmations under the agreed closing process. When the applicable conditions are met, the buyer’s lawyer registers the transfer and, if financed, the mortgage. Access or keys are then released according to the transaction arrangements.

Closing time cannot be promised in advance. Funds may arrive later in the day, registrations may queue, or a last-minute issue may require attention. Buyers should avoid scheduling movers, contractors, or deliveries on the assumption that access will be available early in the morning.

8. Reports to the buyer and lender after closing

After closing, the lawyer completes the trust accounting and sends a reporting package. It commonly contains copies of registered documents, financial statements, title-insurance materials where applicable, and other key closing records. The lawyer also reports to the lender as required and follows up on post-closing undertakings or registrations that remain outstanding.

What does a real estate lawyer do for a seller?

For a seller, the central legal objective is to deliver the title promised in the agreement, receive the purchase funds, complete required payouts, and account for the balance. The seller’s lawyer generally performs a different but connected set of tasks.

1. Reviews the agreement and gathers payout information

The seller’s lawyer reviews the signed agreement, amendments, title information, closing date, adjustments, chattels, rental items, and any conditions affecting legal completion. The lawyer also obtains information about mortgages, secured lines of credit, liens, property taxes, condominium arrears, or other amounts that may have to be paid from the sale proceeds.

Sellers should disclose these items early. A mortgage payout statement can take time to obtain, and some secured lines of credit remain registered even when the balance appears to be zero. The lawyer must work from formal payout and discharge requirements, not a banking-app screenshot or an estimate from memory.

2. Prepares the transfer and closing documents

The seller’s lawyer prepares or reviews the transfer, statements, directions, undertakings, and other closing documents required by the agreement and Ontario’s registration system. The lawyer arranges the seller’s signing and verifies identity.

Names and marital-status information must be accurate. A difference between the owner’s current name and the name on title, a power of attorney, an estate, a corporation, or a family-law issue may require additional documents and review. Raising these facts early gives the legal team more time to determine what is required.

3. Responds to the buyer’s title questions

After conducting its searches, the buyer’s lawyer may deliver requisitions—formal questions or objections about title and closing documents. The seller’s lawyer reviews them, determines which must be answered under the agreement, and provides documents, explanations, undertakings, or arrangements needed to complete the transaction.

An undertaking is a binding professional promise by a lawyer. It is not casual wording. Undertakings are used carefully for matters that can properly be completed after closing, such as obtaining and registering a mortgage discharge when the lender’s process does not allow it to be registered the same day.

4. Prepares or reviews the statement of adjustments

The seller’s side commonly prepares the statement of adjustments. It starts with the purchase price and adds or subtracts agreed credits, such as the deposit and the parties’ shares of property taxes or condominium fees. The result identifies the balance due from the buyer on closing—not the seller’s final take-home amount.

The seller’s net proceeds are calculated separately. In plain language:

Net sale proceeds = sale price − (mortgage and secured-debt payouts + brokerage remuneration + the legal account + adjustments and other authorized payments). The actual statement may contain additional credits, deductions, holdbacks, or directions specific to the transaction.

 

5. Receives funds, completes payouts, and releases the transfer

On closing, the seller’s lawyer receives the funds from the buyer’s lawyer, deals with the agreed documents and registrations, and authorizes release of the transfer when the closing requirements are satisfied. The lawyer then uses the trust funds to make required and authorized payments.

Typical payments may include the mortgage payout, brokerage account, legal fees and disbursements, tax or condominium amounts, and other directions signed by the seller. Where a mortgage discharge will follow later, the lawyer retains and applies the required funds and follows the lender’s discharge process.

6. Sends the remaining proceeds and final report

Once the required amounts can be paid and the trust accounting is complete, the lawyer sends the remaining sale proceeds using the agreed secure method. The seller later receives a report containing the transaction documents and financial accounting.

The timing and amount of the final proceeds depend on the file. Mortgage payout figures can change with interest or fees, and holdbacks may be required. A preliminary estimate is useful for planning, but it should not be treated as a guaranteed final number.

What does a real estate lawyer not normally do?

Understanding the boundaries of the retainer helps clients involve the right professional and avoid assumptions. Unless specifically retained and qualified to do so, a real estate lawyer does not normally:

  • inspect the building, test systems, identify construction defects, or provide engineering advice;
  • determine the property’s market value or replace an appraisal;
  • negotiate the business terms of the deal after the agreement is firm, except as instructed in relation to a legal issue;
  • guarantee future zoning approvals, renovations, rental income, property condition, or resale value;
  • provide a survey where none exists or physically confirm boundary lines;
  • give tax, accounting, immigration, or investment advice outside the lawyer’s agreed scope; or
  • replace the real estate agent, mortgage broker, lender, insurer, home inspector, accountant, or contractor.

A lawyer may identify that specialist advice is needed. For example, a potential encroachment may call for a surveyor; a structural concern may require an engineer; and a non-resident sale or complex ownership arrangement may require tax advice. The legal retainer should make clear what the firm will and will not handle.

When should you contact the real estate lawyer?

Earlier is usually more useful than later. A buyer can contact a lawyer before signing an offer when the property or proposed terms are unusual, and should do so promptly after acceptance. A seller can contact a lawyer before listing if there is an estate, separation, power of attorney, private mortgage, lien, tenant, co-owner dispute, or known title problem.

For a conventional transaction, contact the lawyer as soon as the agreement is firm. Provide complete information rather than waiting for the closing week. The lawyer needs time to open the file, verify identity, review the agreement, search title, obtain lender or payout instructions, and coordinate with the other side.

What information should buyers and sellers give their lawyer?

Buyer checklist

  • the complete Agreement of Purchase and Sale, schedules, waivers, and amendments;
  • full legal names, contact information, marital status, and identification details requested securely;
  • lender and mortgage-broker contact details;
  • how title will be held and whether anyone else is contributing funds;
  • residency, first-time homebuyer, or ownership facts relevant to tax and rebate forms;
  • condominium, tenancy, rental-equipment, new-build, assignment, or other special features; and
  • any travel, signing, funding, or closing-day constraints.

Seller checklist

  • the complete Agreement of Purchase and Sale and amendments;
  • current mortgage and secured line-of-credit details, including account numbers through secure channels;
  • the latest property-tax information and condominium details where applicable;
  • brokerage information and any signed payment directions;
  • full legal names, marital status, identification details, and any name changes;
  • details of tenants, estates, powers of attorney, corporations, separations, liens, or known title concerns; and
  • secure banking instructions for sale proceeds, verified using the firm’s procedure.

Real estate fraud commonly relies on urgency and changed payment instructions. Never rely solely on an unexpected email directing money to a new account. Confirm trust-payment instructions through a known telephone number or the firm’s secure verification process.

Frequently asked questions

Does the buyer and seller use the same lawyer in Ontario?

Usually, each side has separate legal representation. The Law Society’s professional rules restrict a lawyer from acting for both transferor and transferee except in defined circumstances. Separate representation avoids divided loyalty when the parties’ interests differ or a closing problem arises.

Does the lawyer review the home inspection?

The lawyer may review contractual wording connected to an inspection condition, but does not perform the inspection or give an opinion on the building’s physical condition. A qualified inspector or other technical professional should address physical defects.

Does the lawyer guarantee clear title?

No. The lawyer searches title, evaluates legal issues, considers reasonable ways to assure title, and advises the client. Title insurance may cover specified risks, subject to exclusions and limits, but neither the search nor the policy is a promise that no issue can ever arise.

Who calculates the money needed on closing?

The buyer’s lawyer calculates the trust funds required after considering the purchase balance, deposit, net mortgage advance, taxes, adjustments, legal account, registrations, title insurance, and other items. The final figure may not be available until lender instructions and the statement of adjustments are complete.

Who pays the seller’s mortgage?

The seller’s lawyer generally pays the mortgage and other secured amounts that must be cleared from the sale proceeds, using formal payout instructions. The lawyer then follows the lender’s process to obtain and register the discharge where required.

Can the whole closing be done virtually?

Many residential files can be completed with remote meetings, permitted identity verification, and electronic signing, but the process depends on the lender, client, documents, and legal requirements. Confirm the procedure early, particularly if a party will be outside Ontario or Canada.

How much does a real estate lawyer cost?

The cost depends on whether the file is a purchase or sale and on the property, financing, searches, platform charges, third-party costs, and non-standard work. Ask for a written quote that distinguishes the legal fee, HST, standard disbursements, government charges, insurance, and transaction-specific amounts. A low headline fee is not necessarily the total legal account.

The practical next step

A real estate lawyer’s value is not limited to the few minutes when documents are signed. The legal work begins with the contract and title, continues through financing, funds, and registration, and ends only after the trust accounting and post-closing obligations are addressed.

If you are buying, selling, or refinancing an Ontario property, contact Khan Law early with the agreement and the facts that make the transaction unusual. Ask for a transaction-specific written quote and a clear list of the documents, funds, and deadlines required for your closing
