In Ontario, inheritances are generally excluded from the division of property if kept entirely separate. However, if you plan to use an expected inheritance from your living parents to pay down a joint mortgage or renovate your shared matrimonial home, you must sign a marriage contract (prenup) to protect those funds, as the Family Law Act automatically shares the value of the matrimonial home upon separation.
Discussing future wealth can be uncomfortable, especially when it involves an inheritance from parents who are still alive and well. 💰 However, for many young couples in cities like Toronto, Mississauga, and Ottawa, parental wealth transfers are the only way they will ever afford to enter the local real estate market. An expected inheritance is a major financial milestone, but under Ontario family law, how you use that money during your marriage dictates who gets it if you ever divorce.
A marriage contract (commonly known as a prenup) is a vital tool for protecting intergenerational wealth. Without a clear legal agreement, pouring your future inherited cash into a joint bank account or using it to upgrade the family home will legally “mingle” the funds. Once mingled, the inheritance loses its protected status and becomes part of your Net Family Property, meaning your spouse could walk away with half of your parents’ hard-earned money. A properly drafted Ontario marriage contract prevents this outcome.
Step-by-Step Process in Ontario
Addressing an inheritance that has not even happened yet requires careful legal drafting. 📝 You and your partner must follow specific steps to ensure the agreement is legally binding and will hold up in the Superior Court of Justice decades from now.
Step 1: Have an Open Financial Conversation
Before involving lawyers, you must communicate with your partner and, if appropriate, your parents. Explain that the goal of the contract is not to plan for a divorce, but to respect the wishes of the parents who are passing down the wealth. Full financial disclosure is required in Ontario, so both spouses must honestly list their current debts, assets, and the anticipated nature of the future inheritance.
Step 2: Define the Scope of the Expected Inheritance
Will your parents leave you a specific dollar amount, a percentage of their estate, or a physical piece of real estate? 🏘️ Your Ontario law firm will need to draft clauses that capture “future gifts and inheritances from any source” to ensure that whether you receive $50,000 CAD in cash or a family cottage in Muskoka, the asset is clearly identified as your sole property.
Step 3: Draft the “Tracing” and “Matrimonial Home” Clauses
This is the most critical step. Your lawyer must draft a clause overriding the standard rules of the Ontario Family Law Act regarding the matrimonial home. The contract must state that if you invest your future inherited funds into buying, repairing, or paying off the mortgage of the home you both live in, you have a guaranteed right to deduct that specific dollar amount before any profits are split upon separation.
Step 4: Obtain Independent Legal Advice (ILA)
A prenup in Ontario is highly vulnerable to being thrown out by a judge if both parties do not fully understand what they are signing. ⚖️ Your partner cannot use your lawyer. They must hire their own independent lawyer to review the contract, explain how it impacts their rights to equalization and spousal support, and sign a Certificate of Independent Legal Advice.
Step 5: Sign and Store the Marriage Contract
Once both lawyers have approved the document, you and your partner must sign it in the presence of witnesses. Original copies should be kept securely by both law firms, and you should store a digital copy in a safe place. This ensures the document is easily retrievable if an inheritance actually arrives ten or twenty years down the line.
How Much Does it Cost in Ontario?
Drafting a marriage contract is an investment in your financial future, and cutting corners can cost you hundreds of thousands of dollars later. 💵
- Drafting Lawyer Fees: Hiring an experienced Ontario family lawyer to draft a comprehensive prenup typically costs between $2,500 and $5,000 CAD, depending on the complexity of the future estate.
- Independent Legal Advice (ILA): Your partner’s lawyer will generally charge between $1,000 and $2,000 CAD to review the contract, negotiate minor changes, and sign the ILA certificate.
- Notary/Witness Fees: Usually included in the lawyer’s retainer, but if done separately, expect to pay around $100 CAD for basic witnessing and commissioning.
| Use of Inheritance During Marriage | Default Ontario Law (Without Prenup) | Outcome With a Valid Prenup |
|---|---|---|
| Kept in a separate solo bank account | Protected (Excluded from NFP) | Protected |
| Used to buy a joint family car | Likely split 50/50 | Protected (if traced) |
| Used to pay off the Matrimonial Home mortgage | Not Protected (Shared 50/50) | Fully Protected and Deducted |
How Long Does the Process Take?
As of May 2026, a standard marriage contract covering expected inheritances takes about 2 to 4 months to complete. ⌛ This timeline includes the initial consultation, financial disclosure, drafting the first version, allowing your partner’s lawyer time to review it, and scheduling the final signing appointment. You should never rush a prenup right before a wedding, as a judge might view a rushed signing as coercion.
Frequently Asked Questions (FAQ)
What happens if my parents give me an early inheritance as a cash gift while they are alive?
In Ontario, gifts received from a third party during the marriage are treated similarly to inheritances. A well-drafted marriage contract will explicitly cover “gifts, advances on inheritances, and testamentary bequests,” ensuring that money given to you while your parents are still living enjoys the exact same protection as money left in a Will.
Do we need to update the prenup when my parents actually pass away?Generally, no. If the original marriage contract is properly drafted with broad, forward-looking language regarding “expected” or “future” inheritances, it will automatically apply when the funds actually materialize. However, if the nature of the inheritance is drastically different than expected (e.g., inheriting a massive operating business instead of cash), a quick review with your lawyer is highly recommended.

Can the contract stop my spouse from claiming spousal support?Yes, an Ontario marriage contract can include a waiver of spousal support. However, support waivers are strictly scrutinized by the Superior Court of Justice. If the waiver leaves your spouse in absolute poverty after a long marriage while you sit on a multi-million dollar inheritance, a judge has the power to override the support section of the contract. The inheritance protection, however, usually remains intact.

What if we move out of Ontario? Will the contract still protect my inheritance?Most Canadian provinces respect marriage contracts signed in Ontario, provided they meet basic fairness and ILA standards. However, family laws differ greatly (for example, Quebec uses the Civil Code). If you move to another province or country, you must have a local family law firm review your contract to ensure it complies with the laws of your new jurisdiction.
