Spousal support in Ontario is not automatically given. A lot of people assume that the moment a marriage or common-law relationship ends, the higher earner starts writing cheques. That is one of the biggest myths in family law, and part of why many support claims get reduced or rejected.
We’re an Ontario law firm and have lost of clients wondering what causes spousal support to be denied, or want to learn how to not pay spousal support that you do not believe you owe. This legal guide walks through how entitlement actually works under the Family Law Act, the most common reasons support claims gets denied, and the legitimate ways to limit or avoid it.
Where Your Spousal Support Obligations Actually Come From
Before you can work out how to reduce or avoid support, you need to know where the obligation comes from in the first place. In Ontario, your spousal support obligations flow from two sources: any domestic contract you have signed, such as a marriage contract or cohabitation agreement, and the Family Law Act.
Section 30 of the Family Law Act, sets the baseline. It says every spouse has an obligation to support the other spouse in accordance with need, to the extent they are capable of doing so. The factors of need and capability of supporting a spouse are always looked at within the context of that specific relationship and the parties incomes, and expenses.
The word spouse matters too. Under section 29 of the Family Law Act, the support rules reach well beyond married couples. Two people who have lived together continuously for at least three years, or who are in a relationship of some permanence and share a child, can each qualify as spouses for support purposes.
“We were never married, so I am safe?”
In a recent case, Climans v. Latner, 2020 ONCA 554 (CanLII), the Ontario Court of Appeal upheld a finding that parties who were unmarried and did not have children together were indeed spouses despite maintaining separate residences. So the common belief that “we were never married, so I am safe” does not hold up. Whether you are getting married in Ontario or simply in a relationship these rules can apply to you. If you are wondering whether or not you need a prenup for common-law relationships , you should check out our guide on the matter.
When Is Spousal Support Denied in Ontario?
Courts deny or sharply reduce spousal support in a handful of situations. If your circumstances look like any of the following, it is worth getting advice early.
There is no entitlement to begin with
Entitlement is the first hurdle, and many claims fail right here. Ontario courts generally recognise three bases for support: compensatory, where one spouse gave up income or opportunities for the relationship; non-compensatory or needs-based, where one spouse genuinely cannot meet their needs and the other can help; and contractual, where a marriage contract, cohabitation agreement, or separation agreement created the right. Section 33(8) of the Family Law Act frames a spousal support order around recognising a spouse’s contribution to the relationship, sharing child-related costs, helping a spouse become self-supporting, and relieving hardship. If none of those purposes are engaged, there may be nothing to award.
Both spouses are financially independent
If you both kept your careers, earned comparable incomes, and neither of you gave anything up for the relationship, a court may find there is no economic disadvantage to compensate and no real need to meet. Section 33(9) lists the factors a court weighs, including each person’s current and future means, their capacity to provide for themselves, and their age and health. You can also read the province’s plain-language overview of spousal support on Ontario.ca.
Marriage contracts
“For better or worse” covers a lot. A marriage contract covers the rest.
Already married? It’s not too late to put your own agreement in place. No courtroom, no drama.
The relationship was short with little interdependence
Length of cohabitation is one of the express factors under section 33(9). The shorter the relationship and the less your finances were intertwined, the weaker a support claim tends to be, especially where there are no children and no career sacrifices. Keep in mind that the three-year threshold in section 29 defines who counts as a common-law spouse. It is not a promise that support will or will not be ordered after three years .
A spouse can support themselves but chooses not to
Entitlement is not a free pass to avoid work. Section 33(9) directs the court to consider a spouse’s capacity to contribute to their own support and the measures available to become self-supporting. Where a person could reasonably work or retrain and does not, a court can impute income, meaning it treats them as earning what they realistically could, and adjust or deny support accordingly.
A valid agreement limits or waives support
A properly negotiated marriage contract or cohabitation agreement can limit or even waive support. How solid those agreements really are is the next thing worth understanding.
How to Not Pay Spousal Support: A First Principles Look
Here is the honest framework. Your spousal support exposure is governed by the contents of your domestic contract and the Family Law Act, in that order, but with a major catch: an Ontario court can override your contract if it decides the deal was unfair.
Start with the contract. Section 52 of the Family Law Act expressly allows two people who are married or intend to marry to agree on their respective rights and obligations, and that list includes support obligations. Section 53 says the same for couples who live together. In plain terms, you can address spousal support in a marriage contract or cohabitation agreement and agree to limit it or waive it. The claim that you simply cannot opt out of spousal support in Ontario is not accurate. You can. The real question is whether the waiver will survive.
That is where enforceability comes in. Section 33(4) gives a court the power to set aside a support provision or a waiver of support, even where your contract expressly tries to exclude the issue when the waiver would create unconscionable circumstances.
Court cases have found unconscionable circumstances when the person giving up support would end up relying on public assistance, or where there is a default in payments owed under the contract. On top of that, section 56(4) lets a court set aside the entire contract where one party failed to disclose significant assets or debts, did not understand what they were signing, or on ordinary contract law grounds such as duress. It is the same reason we are often asked whether cohabitation agreements hold up in court.
Put those together and the strategy becomes clear. A waiver signed without disclosure or legal advice is the easiest thing in the world for a court to ignore, which sends you straight back to the default rules in the Family Law Act. A waiver built on full financial disclosure, independent legal advice for both people, and fair terms is far harder to unwind. If limiting support matters to you, the quality of the agreement is everything. The same logic applies if you are already married and want to set terms now through a postnuptial agreement.
Negotiate a clean trade off
Spouses often agree that no ongoing support will be paid in exchange for something of comparable value, such as a larger share of property or the family home. A well-drafted separation agreement records the deal, and working through divorce mediation can help you reach it without a fight.
Consider a lump sum instead of monthly payments
Section 34 of the Family Law Act allows support to be ordered as a lump sum rather than periodic payments. Agreeing to a one-time lump sum can give both of you a clean break and cap your total exposure. Before you name a figure, calculate your spousal support range so you know what the lump sum is standing in for.
Show that your former spouse is self-supporting
Evidence of comparable income, marketable skills, or an unreasonable refusal to work goes directly to the section 33(9) factors and can shrink or end an award.
Apply to vary when circumstances change
If your income drops through illness or job loss, or your former spouse’s situation improves, you can ask to vary or terminate support. Keep careful records of everything.
What Does Not Work (and Can Backfire)
Two moves reliably blow up in court. The first is deliberately earning less, quitting a job or turning down work to look broke. Courts respond by imputing income under the section 33(9). The second is hiding assets or income. Incomplete or dishonest disclosure is one of the express grounds under section 56(4) for tearing up an agreement, and it wrecks your credibility for everything else. The path to paying less runs through transparency, not concealment.

Spousal Support Myths, Sorted
Myth: my ex cheated, so they get nothing. Section 33(10) is blunt. The obligation to provide support exists without regard to the conduct of either spouse. The only narrow exception is a course of conduct so unconscionable that it amounts to an obvious and gross repudiation of the relationship, which is a very high bar. Adultery on its own will not be determinative of spousal support.
Myth: support always lasts forever. Duration depends on the circumstances, including the length of cohabitation under section 33(9). Many awards are time-limited, and most can be reviewed or varied later. Even an indefinite support award does not mean support will continue forever. Per Section 7.5.2 of the Spousal Support Advisory Guidelines , ‘support may even be terminated if the basis of the entitlement disappears’. Hancock v. Rutherford, 2018 ONSC 556 is a case that confirmed that it is appropriate to set a termination date on spousal support even when a party is entitled to indefinite support. Typically, the parties do not set a firm termination date but rather a “review date” upon which spousal support entitlement will be reassessed.
Myth: the guidelines are the law. The federal Spousal Support Advisory Guidelines suggest ranges for amount and duration once entitlement is established, but they are advisory, not binding legislation. In court, these Guidelines
Myth: common-law partners never pay. As section 29 makes clear, common-law partners can both owe and receive support once they meet the cohabitation test, so a sound cohabitation agreement matters just as much as a marriage contract.
Frequently Asked Questions
Can spousal support be denied in Ontario?
Yes. If a spouse cannot show entitlement on compensatory, needs-based, or contractual grounds, support can be denied. Short relationships, financial independence, and a refusal to become self-supporting are common reasons, and each connects to the factors in section 33(9) of the Family Law Act.
Can you waive spousal support in a marriage contract in Ontario?
You can. Section 52 of the Family Law Act lets couples agree on support obligations, including waiving them. A court can still set the waiver aside under section 33(4) if it creates unconscionable circumstances, leaves someone needing public assistance, or under section 56(4) for non-disclosure or lack of understanding.
Does adultery affect spousal support in Ontario?
Generally no. Section 33(10) says the support obligation exists without regard to conduct, with a narrow exception for conduct so unconscionable that it amounts to an obvious and gross repudiation of the relationship.
Do common-law partners have to pay spousal support?
They can. Under section 29, partners who cohabited continuously for at least three years, or who share a child in a relationship of some permanence, can qualify as spouses for support. Maintaining separate residences does not always preclude you from a finding of common law status.
