In Ontario, lottery winnings or inheritances received before your marriage are generally deducted from your Net Family Property during a divorce. However, if you use those winnings to purchase or pay off a matrimonial home, that money loses its protected status. A marriage contract is the only way to safeguard pre-marital cash invested into the family residence.
Winning the lottery, receiving a massive legal settlement, or inheriting a large sum of cash before you get married is a life-changing event. Naturally, you want to use that money to build a comfortable life for you and your future spouse. In Ontario, the Family Law Act has a general rule: whatever net worth you bring into the marriage on your wedding day belongs to you, and is deducted from the equalization calculation if you separate. 💵
However, there is a massive, highly dangerous exception to this rule: the Matrimonial Home. If a resident in Windsor, London, or Toronto uses their pre-marital $1,000,000 Lotto Max winnings to buy a house that the couple moves into after the wedding, that entire million dollars suddenly becomes subject to a 50/50 split. The law does not care where the money came from if it is sunk into the primary family residence. To stop your windfall from being unintentionally divided, you must execute a legally binding marriage contract.

Step-by-Step Process to Protect Windfalls in Ontario
Protecting a sudden influx of cash requires immediate strategic planning. Do not commingle your funds with your partner’s accounts until a contract is signed.
Step 1: Segregate the Funds Immediately
The moment you receive your winnings or inheritance, place the funds in a brand-new, sole bank account in your name only. Do not put your fiancé’s name on the account, and do not use the money to pay off their personal debts just yet. Keeping the cash cleanly separated makes it much easier for your lawyer to trace the origin of the funds if they are ever challenged in the Superior Court of Justice. 💰
Step 2: Negotiate the Matrimonial Home Clause
You must have your lawyer draft a marriage contract specifically targeting Section 52 of the Family Law Act. The contract will contain a “Matrimonial Home Exemption” clause. This clause explicitly states that if you use your pre-marital winnings to purchase the house, pay down the mortgage, or fund major renovations, you get that specific dollar amount back before the remaining equity of the home is divided 50/50.
Step 3: Provide Full Financial Disclosure
A marriage contract is only valid if there are no secrets. You must provide official bank statements proving the exact amount of your lottery winnings or windfall. Your partner must also disclose their entire financial situation, including any debts they are bringing into the marriage. This ensures the contract is signed in good faith. 📊
Step 4: Execute with Independent Legal Advice (ILA)
Your future spouse must take the drafted contract to an independent lawyer. Because they are signing away their statutory right to half the value of the matrimonial home, an Ontario judge will invalidate the prenup if they did not receive separate, objective legal counsel explaining exactly what they are giving up.
How Much Does it Cost in Ontario?
Drafting a prenup is incredibly affordable compared to accidentally giving away half of a million-dollar windfall. 💼
- Drafting the Marriage Contract: A standard prenup focused heavily on protecting pre-marital cash and the matrimonial home generally costs $2,000 CAD to $4,000 CAD.
- Independent Legal Advice (ILA): The spouse reviewing the document will pay their independent lawyer approximately $800 CAD to $1,500 CAD.
- Potential Savings: Properly isolating a $500,000 down payment saves you exactly $250,000 CAD in the event of a divorce.
| How Winnings are Used | Without a Marriage Contract | With a Marriage Contract |
|---|---|---|
| Kept in a sole bank account | Deducted from equalization (Safe). Interest earned may be shared. | Explicitly excluded. Both principal and interest can be protected. |
| Used to buy the Matrimonial Home | Lost the deduction. The home’s total value is split 50/50. | The initial investment is protected and returned to you; only the growth is shared. |
| Put into a Joint Account | Commingled. Presumed to be a gift to the marriage, potentially split 50/50. | Can specify tracing rules to reclaim your original principal. |
How Long Does the Process Take?
Do not wait until the week before the wedding or the closing date of the house purchase to handle this.
- Initial Drafting: Gathering bank records and drafting the customized contract takes about 2 to 4 weeks.
- Partner’s Review: Your partner booking an appointment with their own lawyer for ILA usually takes 2 to 3 weeks.
- Final Revisions & Signing: Allow a final 1 to 2 weeks for any requested tweaks before the final signatures are collected.
Frequently Asked Questions (FAQ)
What happens if I win the lottery AFTER we are already married?
In Ontario, any wealth generated or acquired during the marriage is generally subject to equalization. Unless you already have a postnuptial agreement in place that says otherwise, lottery winnings acquired during the marriage will be shared equally in a divorce.
Does a prenup protect me from Spousal Support?
While a marriage contract can protect your underlying capital (the winnings), if that cash generates massive interest income, it could affect spousal support calculations. You can include a spousal support waiver in the prenup, but courts can review it for extreme unfairness.
What if my parents gift me the money for a down payment?
Gifts and inheritances are generally exempt from equalization. However, just like lottery winnings, if you put that gifted money into a matrimonial home, it loses its protection. A marriage contract or a legally registered Deed of Gift is required to protect it.
Can we write the prenup ourselves to save money?
Technically yes, but it is highly dangerous. “Do-it-yourself” prenups are routinely thrown out by Ontario judges because they often lack proper financial disclosure and Independent Legal Advice. Always use a professional law firm.
