How a marriage contract affects spousal support claims in Manitoba.

In Manitoba, you can use a marriage contract to limit or completely waive your right to spousal support. However, if that waiver causes extreme financial hardship at the time of your separation, a judge at the Court of King’s Bench has the legal authority to override the contract and order support anyway.

Discussing money before walking down the aisle can feel uncomfortable, but a marriage contract is one of the best ways to protect your financial future. In Canada, many couples use these agreements to decide in advance how their assets will be divided if the relationship ends. But when it comes to ongoing financial payments, the rules get a bit more complicated.

A common question from couples in Winnipeg, Brandon, and Steinbach is whether they can completely cancel out spousal support in their contract. While Manitoba law allows you to include these waivers, there are strict rules about when a court will actually enforce them. This guide explains how marriage contracts affect spousal support claims in the province as of April 2026.

Step-by-Step Process for Drafting a Support Clause in Manitoba

Creating a marriage contract that a judge will respect takes careful planning. If you simply write “no spousal support ever” on a napkin, it will almost certainly be thrown out of court. Here are the steps your law firm will generally follow to create a legally sound agreement .

Step 1: Full Financial Disclosure

Before you can waive your right to support, you must know exactly what you are giving up. Both partners must provide a complete, honest list of their current incomes, debts, and assets 📊. This includes providing recent Canada Revenue Agency (CRA) tax returns and pay stubs. Hiding a bank account or a business asset is a quick way to have the entire contract invalidated later.

Step 2: Negotiating the Terms

Next, you and your partner will discuss what feels fair. You might agree to waive spousal support entirely, or you might set a cap. For example, you could agree that support will only be paid for a maximum of three years, or that the monthly amount will not exceed $1,500 CAD. This allows you to create a custom safety net.

Step 3: Obtaining Independent Legal Advice

This is the most critical step in Manitoba. For a waiver of spousal support to be binding, both spouses must hire their own, separate family lawyers. Your lawyer will explain the long-term consequences of giving up your right to support. Once you understand the risks, both you and your lawyer will sign a Certificate of Independent Legal Advice attached to the contract .

How Much Does it Cost in Manitoba?

Drafting a marriage contract is an investment in your future security. Because both parties need their own legal representation, the costs are usually divided between two law firms.

  • Primary Drafting Lawyer: The lawyer who actually writes the contract generally charges between $2,000 and $4,500 CAD, depending on the complexity of your finances.
  • Reviewing Lawyer (ILA): The second lawyer, who reviews the document for the other partner, typically charges between $750 and $1,500 CAD.
  • Court Filing Fees: You do not need to file a marriage contract with the court when you sign it. You simply keep it in a safe place. Therefore, there are no immediate government fees.

How Long Does the Process Take?

You should never rush a marriage contract. Start the process well before your wedding day. On average, gathering financial documents, drafting the agreement, and negotiating the final terms takes about 2 to 4 months 📅. If you hand a complicated contract to your partner the week before the wedding, a Manitoba judge might later rule that they signed it under “duress” (extreme pressure), which could make the spousal support waiver useless.

Frequently Asked Questions (FAQ)

Can we waive child support in our marriage contract?

Absolutely not. In Canada, child support is the legal right of the child, not the parents. A Manitoba court will instantly strike down any clause in a contract that attempts to waive or illegally reduce child support payments.

Do common-law partners need a marriage contract?

Common-law partners can sign a very similar document called a “cohabitation agreement.” In Manitoba, common-law couples have the same rights to spousal support as married couples after living together for three years (or one year if they have a child), so having an agreement is highly recommended.

What if my spouse tricked me about their income?

If one partner deliberately lied or hid significant assets during the financial disclosure step, the Court of King’s Bench can completely throw out the marriage contract. Honesty is a strict legal requirement.

Will the court care about parenting time?

Yes. If you waived spousal support but ended up with the majority of the parenting time (decision-making responsibility) after the split, your ability to work full-time might be impacted. A judge will heavily consider your parenting responsibilities if you ask them to override a support waiver.
