Buying a GTA Home Together: Co-Ownership Agreement Checklist

Buying with family or friends requires more than splitting the down payment. Co-buyers should agree on ownership, money, decisions and exits before offering.

Create the agreement before the offer creates pressure

The direct answer is that people buying a GTA home together should obtain independent legal advice, choose an ownership structure, confirm financing and sign a detailed co-ownership agreement before making an unconditional commitment. The agreement should address contributions, home use, decisions, repairs, missed payments, disputes, new occupants, exits, disability and death.

Ontario's co-ownership guide says buying with others is a major financial and living commitment. It recommends a legal co-ownership agreement to clarify rights and obligations and protect participants in disputes. Sam Kamra encourages co-buyers to discuss difficult scenarios while everyone is cooperative, not after the home has closed.

Match title, shares and financing

Ask the lawyers to explain possible title structures, including joint tenancy and tenancy in common, and how each interacts with ownership shares, succession, estate plans and the parties' intentions. Do not assume equal names on title automatically reflect unequal deposits or desired proceeds. Record each person's initial contribution and whether any amount is a gift, loan or additional equity.

Send the proposed ownership and agreement structure to the lender or licensed mortgage professional early. Ontario notes that co-owners seeking a mortgage must work together and share income, asset, debt and credit information. A private promise that one owner will pay only a percentage may not change obligations owed to the lender under the mortgage. Each borrower should understand the mortgage contract and obtain individual advice where interests differ.

Build a complete household budget

List the deposit, remaining down payment, land transfer taxes, legal fees, inspection, appraisal, moving costs and immediate repairs. Then allocate mortgage payments, property taxes, utilities, insurance, condominium fees, maintenance and a capital reserve. State whether shares are fixed or change when one person contributes more, and how advances are documented and repaid.

Create a dedicated payment process with clear due dates, records and account access. Set a reserve target for roofs, mechanical systems, special assessments or income interruptions. FSRA advises mortgage shoppers to consider the total ownership cost and how they would manage if income fell or expenses rose. The Toronto home-buying budget guide can support the shared cash plan.

Define use, decisions and upkeep

Describe private and common areas, parking, storage, guests, pets, smoking, home businesses, renovations and new partners or occupants. If part of the property will be rented, verify zoning, building, fire, insurance, mortgage and tenancy implications rather than assuming the household agreement overrides external rules.

Set decision thresholds: routine maintenance may need one coordinator, while borrowing, major renovations, leasing, refinancing or sale may require unanimous approval. Define work responsibilities and whether unpaid labour earns credit. Ontario's guide suggests addressing financial contributions, work commitments, operating expenses, major repairs, insurance, negligence and misuse of common funds. Sam Kamra's buyer resources can help organize the practical questions, while additional property guidance supports planning.

Write exit, default and life-event rules

The agreement should state what happens if a co-owner misses payments, wants to move, separates from a partner, becomes disabled, dies, faces creditor problems or wants to sell. Include notice, valuation, appraisal selection, buyout funding, first-offer rights, sale procedures, transaction costs and timelines. Decide how improvements and unequal contributions affect a payout without promising that a chosen formula will always match market value.

Add a dispute process such as negotiation followed by mediation or another lawyer-approved route. Coordinate wills, powers of attorney, beneficiary planning and property insurance with the title structure; a co-ownership agreement alone may not solve every estate or family-law issue. Public evidence supports decisions when interpreted carefully; CB Herald's discussion of Sam Kamra and public LTB data illustrates that principle, while Barchart's report on the RealEstateBuyer.ca launch covers Sam Kamra's broader property-services work. The conclusion is simple: align the title, mortgage and private agreement before buying. Bring this checklist to separate lawyers, the lender, insurer and real-estate professional before submitting an offer.
