Planning a wedding comes with endless decisions, from choosing a venue to crafting the perfect menu. In the midst of the hustle and bustle, many couples put off important conversations, like whether to create a Prenuptial Agreement. Taking the time to talk about this can prevent misunderstandings, protect your assets, and give you and your partner peace of mind.

Here, we’ll discuss everything you need to know about Prenuptial Agreements so you can approach the subject with clarity and confidence.

What Is a Prenuptial Agreement in Ontario?

A Prenuptial Agreement, or Prenup, is a legally binding marriage contract created before marriage. It is considered a domestic contract under Ontario’s Family Law Act.

This Agreement sets out how a couple’s assets, debts, property, and financial responsibilities will be handled during separation, divorce, or death. In these situations, a Prenup acts as a guide for resolving financial matters, including how assets and obligations will be divided. By setting clear expectations in advance, it reduces the risk of disputes later on.

Other names for a Prenuptial Agreement include:

• Marriage Contract
• Premarital Agreement
• Antenuptial Agreement

Why Might Couples Avoid Discussing a Prenup?

Marriage is often viewed as a union built on love and commitment, so introducing a Prenup can feel unromantic or even unsettling. Talking about a Prenup may raise fears of divorce or emphasize financial differences, which can lead to misunderstandings between partners.

That said, a Prenup can facilitate greater transparency, reducing conflict down the road, and provide financial security to both spouses.

Why Should You Get a Prenuptial Agreement in Ontario?

Marriage changes your legal rights and financial responsibilities. A Prenup encourages open, honest discussion about the legal realities of marriage and protects both partners.

Without a Prenup, Ontario courts divide marital property according to the Family Law Act. The law generally requires equal division of assets acquired during marriage. A Prenup lets you customize how you want to divide your property and assets in a way that you both agree upon.

A prenuptial Agreement is a good idea for everyone involved because it can:

• Encourage transparency and trust: Promote open discussion about finances, reducing misunderstandings and potential disputes.
• Provide clarity: Ensure both parties are on the same page, which can reduce stress and tension during the separation process.
• Protect both parties’ finances: Safeguard the wealthier partner from sharing a substantial portion of their wealth and ensure the less financially secure partner is supported.
• Avoid a lengthy court process: With important financial matters already decided, a Prenup can prevent the need to go to court.
• Provide both partners with greater control: Avoiding the court process ensures the courts don’t make financial decisions for you, and they remain within your control.

What Can You Do With a Prenuptial Agreement?

A Prenuptial Agreement is designed to help you and your spouse protect your financial interests. You can use this Agreement to protect yourself in the following ways:

• Protect ownership of personal and business assets: Prevent personal property, inheritance, investments, or businesses acquired before marriage from being treated as joint assets.
  
• Address debts and liabilities: Prevent one spouse from becoming responsible for the other’s premarital or significant debts.
  
• Set clear terms for spousal support: Outline expectations for financial support after separation, reducing uncertainty and conflict.
• Ensure fairness for children: Preserve assets for children and protect their inheritance rights.

Prenuptial Agreement vs. Marriage Contract

In Ontario, a Prenuptial Agreement is legally the same as a marriage contract. Both outline how assets, property, and finances will be handled if the spouses separate. The difference lies in timing:

• Prenuptial Agreement – Signed before marriage.
• Postnuptial Agreement – Signed after marriage, but still considered a marriage contract.
• Marriage Contract – A broad term that applies to both.

For couples in a common-law relationship, a Cohabitation Agreement can serve a similar purpose. If the partners later get married, their Cohabitation Agreement usually becomes a Marriage Contract automatically.

How Does a Prenuptial Agreement Work in Ontario?

A Prenuptial Agreement is created before marriage, and takes effect if a couple separates, divorces, or if one spouse passes away. When both spouses follow the Agreement, the separation process is often faster, less expensive, and less stressful.

If one spouse contests the prenup, they can take the other to court, where a judge will review it. The court will consider whether the contract was created fairly and in compliance with Ontario’s Family Law Act before enforcing it. If the court deems it necessary, it can strike out or change the prenup’s terms.

Can You Get a Prenuptial Agreement After Marriage?

No. As the name suggests, a Prenuptial Agreement must be signed before a couple ties the knot.

If you are already married and want similar protections, Ontario law allows a different type of domestic contract called a Postnuptial Agreement. This type of contract operates under the same legal framework as a Prenup, but it is created and signed after marriage.

Information to Include in an Ontario Prenuptial Agreement

To make sure your Prenuptial Agreement clearly explains how assets and property are managed, it should include the following details:

1. Basic Information About the Spouses

List your full legal name and current address, as well as your spouse’s, to clearly identify who is bound by the Agreement.

2. Separate and Shared Assets

State which assets and property will remain individually owned and which will be treated as joint property during and after the marriage. You should also outline how shared assets will be divided if the marriage ends. Without a Prenuptial Agreement, Ontario courts may divide shared property equally (50/50) or in another way they consider fair (equitable distribution).

3. Separate and Joint Debts

List all existing debts and specify which belong to each spouse individually and which are shared. Make it clear that individual debts remain the responsibility of the spouse who incurred them. 

For joint debts such as co-signed loans, shared credit cards, or a mortgage, set out how repayment will be handled. Many couples choose an even split, but you can agree to another arrangement that better fits your situation.

4. Children’s Details

If you have children, include their full names in the Agreement to ensure there’s no confusion about who certain clauses apply to.

While the court decides custody and child support, you can detail children’s inheritance rights and estate planning. You can also include provisions such as:

• Education and funding plans
• Guidance on values, cultural practices, or religious upbringing
• Inheritance rights and protection of financial interests

5. Spousal Support

Spousal support, also called alimony or maintenance, is the money that one spouse pays the other after a separation or divorce. Adding this is optional, and you can include:

• Who will pay and who will receive spousal support
• The specific amount of payments made
• Frequency of the payments
• Payment method
• Conditions for starting, changing, or ending payments (e.g., payable only if the marriage lasts five years or until the recipient remarries) 

If you don’t address spousal support and end up going to court, a judge may make spousal support decisions for you.

6. Spousal Inheritance Rights

Your spouse may have rights to your property when you pass away, even if your Will says otherwise. You can use your Prenup to:

• Limit or define those rights
• Leave certain property to your children or relatives
• Protect family assets, such as a cottage or business

For the strongest protection, ensure your Prenuptial Agreement and your Will are consistent and work together.

7. Financial Responsibilities and Bank Accounts

Clarify how joint and personal accounts are handled, how credit is obtained, and outline any spending agreements. You can also include who pays certain bills, who manages and pays taxes, and how credit is obtained or managed. 

8. Parental and Household Roles

Indicate who will be a stay-at-home parent once you have children.

What Cannot Be Included in an Ontario Prenuptial Agreement?

While a Prenuptial Agreement can cover several financial matters, Ontario’s Family Law Act places limits on what it can address. The following details cannot be addressed in a Prenuptial Agreement:

1. Child Custody or Access

A Prenup cannot determine parenting arrangements, including child custody or access. These decisions are always based on the best interests of the child at the time of separation. The court has final authority over custody matters and may disregard any clause that attempts to set these terms in a Prenup.

2. Rights to the Matrimonial Home

According to the Family Law Act, both spouses have equal rights to live in the matrimonial home, regardless of ownership. A Prenup cannot remove or limit these rights, including the right to share in the home’s value. Unless a court order or Separation Agreement states otherwise, neither spouse can prevent the other from entering the matrimonial home.

3. Provisions That Are Illegal or Against Public Policy

A Prenup cannot require either spouse to commit illegal acts or include terms that override existing laws. Courts will reject any illegal, immoral, or prohibited provisions, which can lead to part or all of the Agreement being set aside. 

Is a Prenuptial Agreement Legally Binding in Ontario?

A Prenuptial Agreement is legally binding in Ontario as long as it meets the requirements for a valid domestic contract. According to Ontario’s Family Law Act, a judge may set aside or invalidate a Prenup for the following reasons:

• Non-compliance with the law: The Agreement must comply with Ontario’s contract laws. Provisions that are unfair or illegal can make the Prenup unenforceable.
  
• Lack of understanding: Both spouses must fully understand the terms and legal implications of the Agreement. If one did not understand any terms within the prenup, a court may invalidate it.
  
• Incomplete financial disclosure: All assets, debts, and financial information must be fully disclosed. Hiding or failing to disclose assets or liabilities can render the Agreement invalid.
  
• Coercion: The Agreement must be signed voluntarily by both parties, without coercion or undue influence.
  
• Extremely unfair terms: If any parts of the Agreement are inherently unfair or unreasonable, the court may update those parts or invalidate the Agreement.
  
• Not in the Best Interest of the Child: If any part of the Agreement isn’t in the best interest of the child, it can be disregarded.

To ensure your Prenup is legally enforceable, it must include the following elements:

• Offer and Acceptance: Both spouses must negotiate the terms and voluntarily sign the Agreement.
  
• Consideration: Each party must exchange something of value, such as spousal rights or agreements on assets.
  
• Mutuality: Both spouses must enter into the Agreement honestly and with truthful intentions.
  
• Legality: The terms cannot violate Ontario law; illegal provisions will make the Agreement unenforceable.
  
• Capacity: Both parties must be legal adults of sound mind when signing the Agreement.

Additionally, a Prenuptial Agreement must:

• Be in writing.
• Be signed and dated by both spouses.
• Be witnessed by at least one adult who isn’t a party to the Agreement
• Be signed after full disclosure of all assets, liabilities, and financial circumstances.

How to Sign a Prenuptial Agreement in Ontario?

To make a Prenuptial Agreement legally valid in Ontario, it must be signed by both spouses in the presence of a witness. The witness should be an adult over 18 who is not a family member and does not have any interest in the Agreement. They must sign and date the document to confirm they have observed the signing.

Having a notary public or commissioner present can add an extra layer of legal verification. However, the Agreement’s enforceability depends primarily on proper witnessing. Signing the Prenup confirms that both spouses understand the terms and are entering into it voluntarily.

Commissioning Your Prenuptial Agreement in Ontario

Having your Prenuptial Agreement formally commissioned is highly recommended in Ontario. Commissioning means each spouse swears or affirms that they are signing the Agreement voluntarily and fully understand its contents. This step makes it difficult for either party to claim that they were pressured into signing or unclear on the Agreement’s terms.

Commissioning also supports enforceability in court. Having the Agreement sworn before an authorized official, like a notary public, provides independent verification of identities and signatures. This creates a clear record of proper execution, deters challenges, and gives judges confidence that the Agreement was signed knowingly and willingly.
