What Happens When You Divorce After a Short Marriage in Ontario?
Divorce after a short marriage in Ontario follows the same legal process as any divorce under the Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), but property division and spousal support are calculated differently when the marriage lasted fewer than 5 years. Ontario courts may reduce the equalization payment pro-rata under Ontario Family Law Act, R.S.O. 1990, c. F.3, s. 5(6) when cohabitation was brief, and spousal support under the Spousal Support Advisory Guidelines typically ranges from 0.5 to 1 year of support for each year of marriage. The total filing fee is $679, the residency requirement is 1 year of ordinary residence in Ontario, and an uncontested divorce after a short marriage in Ontario typically concludes in 4 to 6 months.

Defining a Short Marriage Under Ontario Law
A short marriage in Ontario is generally defined as a marriage lasting fewer than 5 years of cohabitation, which is the threshold established under Ontario Family Law Act, s. 5(6) for courts to consider adjusting the equalization payment. Ontario does not have a statutory definition that labels a marriage as "short" versus "long," but the 5-year marker is the dividing line that Ontario courts consistently apply when determining whether property division should be modified. Marriages lasting less than 1 year, sometimes called brief marriages, receive the most significant adjustments, with equalization potentially reduced to as little as one-fifth of the standard amount.
The duration of cohabitation, not the date of the wedding ceremony, is the relevant period. Ontario courts count the total time the spouses lived together, including any period of cohabitation before the formal marriage. A couple who lived together for 3 years before a 6-month marriage would have their cohabitation period assessed at 3.5 years for equalization purposes under Family Law Act, s. 5(6)(d). This distinction matters significantly for anyone seeking a divorce after a short marriage in Ontario because the cohabitation period directly affects how much of the equalization payment a court may award.
Grounds for Divorce in Ontario: No Minimum Marriage Length
Ontario has no minimum marriage duration requirement to file for divorce. A spouse who was married less than a year can file for divorce on the same grounds as a spouse married for 30 years under Divorce Act, s. 8(2). The three grounds for divorce in Canada are 1 year of living separate and apart, adultery by the other spouse, or physical or mental cruelty that makes continued cohabitation intolerable. The 1-year separation ground is used in approximately 95% of all Canadian divorces.
For a brief marriage divorce, the separation period can sometimes feel disproportionate. A couple married for only 4 months must still wait a full 12 months of separation before the court will grant the divorce, unless one spouse can prove adultery or cruelty. Ontario courts allow spouses to file the divorce application before the 1-year separation is complete, but the Divorce Order will not be granted until the full 365 days have passed. Spouses can also live "separate and apart" under the same roof if they can demonstrate they maintained separate lives, separate bedrooms, and did not hold themselves out as a couple during that period.
Annulment as an Alternative
Some spouses in very short term marriages consider annulment rather than divorce. An annulment declares the marriage void from inception, as though it never existed. Ontario courts grant annulments only in narrow circumstances: one spouse was already married (bigamy), the marriage was never consummated, one spouse lacked mental capacity to consent, one spouse was under the age of consent, or consent was obtained through fraud or duress. An annulment is not a faster path to ending a valid marriage and carries a higher burden of proof than a standard divorce proceeding.
Property Division After a Short Marriage in Ontario
Ontario divides marital property through equalization of net family property (NFP) under Family Law Act, Part I, not through a 50/50 split of assets. Each spouse calculates their NFP by subtracting the value of assets they brought into the marriage (date-of-marriage deductions) and any excluded property (gifts, inheritances) from the value of all assets held on the date of separation. The spouse with the higher NFP pays the other spouse half the difference. In a short marriage, these calculations often result in smaller equalization payments because there has been less time for significant asset accumulation.
The Section 5(6) Reduction for Short Marriages
Under Ontario Family Law Act, s. 5(6)(d), a court may award an equalization payment that is more or less than half the difference between the spouses' NFP values if the court determines that equalizing would be "unconscionable" given that the period of cohabitation was less than 5 years. The unconscionability test is a high bar. The Ontario Court of Appeal has held that circumstances that are merely "unfair," "harsh," or "unjust" do not meet this threshold. The result must "shock the conscience of the court."
For divorce after a short marriage in Ontario, courts have developed a pro-rata formula that reduces the equalization payment proportionally based on the length of cohabitation:
| Years of Cohabitation | Equalization Proportion | Example (Full Equalization = $100,000) |
|---|---|---|
| Less than 1 year | Up to 1/5 (20%) | Up to $20,000 |
| 1 to 2 years | Up to 2/5 (40%) | Up to $40,000 |
| 2 to 3 years | Up to 3/5 (60%) | Up to $60,000 |
| 3 to 4 years | Up to 4/5 (80%) | Up to $80,000 |
| 4 to 5 years | Up to 5/5 (100%) | Up to $100,000 |
| 5+ years | Full equalization (100%) | $100,000 |
This pro-rata approach is not automatic. The court retains discretion to award the full equalization amount even in a short marriage if the circumstances do not meet the unconscionability standard. A spouse seeking a reduced equalization must affirmatively argue and prove that awarding the full amount would shock the conscience of the court given the brevity of the relationship.
The Matrimonial Home Exception
Ontario law contains a critical rule about the matrimonial home that disproportionately affects short marriages. Under Family Law Act, s. 4(1), the value of a matrimonial home owned before the marriage cannot be deducted as a date-of-marriage asset. If one spouse owned a home worth $500,000 before the marriage and the couple lived in it as the matrimonial home, the full $500,000 is included in the owning spouse's NFP calculation with no deduction for its pre-marriage value. In a short marriage of 1 year, the non-owning spouse could potentially claim up to 20% of the equalization amount that includes that $500,000 home value. This rule makes the matrimonial home the single largest financial issue in most short marriage divorces in Ontario.
Spousal Support for Short Marriages in Ontario
Spousal support in Ontario after a short marriage is typically limited in both amount and duration. The Spousal Support Advisory Guidelines (SSAG), which Ontario courts routinely apply, calculate support using the "without child support formula" for marriages without children: the income difference between spouses is multiplied by 1.5% (low end) to 2% (high end) for each year of cohabitation, then divided by 12 for a monthly amount. Duration ranges from 0.5 to 1 year of support per year of marriage.
SSAG Calculation Example: 2-Year Marriage
For a couple married 2 years with no children, where the higher-income spouse earns $120,000 and the lower-income spouse earns $40,000:
- Income difference: $80,000
- Low-end amount: $80,000 x 1.5% x 2 years = $2,400/year ($200/month)
- High-end amount: $80,000 x 2% x 2 years = $3,200/year ($267/month)
- Low-end duration: 2 years x 0.5 = 1 year
- High-end duration: 2 years x 1.0 = 2 years
- Support range: $200 to $267 per month for 1 to 2 years
Ontario courts have discretion to depart from the SSAG ranges. Under Divorce Act, s. 15.2, the court considers the condition, means, needs, and circumstances of each spouse, including the length of cohabitation and the functions performed during the marriage. For a brief marriage divorce where one spouse left employment or relocated, the court may award support for a transitional period to allow the recipient to regain financial independence, even if the SSAG formula produces a nominal amount.
When Spousal Support Is Denied in Short Marriages
Ontario courts frequently deny spousal support entirely in short term marriage divorces when both spouses are self-sufficient, neither spouse sacrificed career opportunities, no children were born during the marriage, and the standard of living during the marriage did not create a significant economic disparity. The SSAG "rule of 65" (which triggers indefinite support when the recipient's age plus years of marriage equals 65) does not apply to marriages under 5 years.
Parenting Arrangements in Short Marriage Divorces
When children are involved in a divorce after a short marriage in Ontario, the Divorce Act, s. 16.1 requires courts to make parenting orders based on the best interests of the child. The 2021 amendments to the Divorce Act replaced the former terminology with "parenting time" and "decision-making responsibility" to better reflect the child-focused approach. Ontario courts must consider the child's physical, emotional, and psychological safety, security, and well-being as the primary factors under Divorce Act, s. 16(2).
The length of the marriage does not diminish either parent's rights to parenting time. A parent who was married for only 8 months has the same entitlement to seek parenting time as a parent married for 20 years. Ontario courts assess 14 specific factors under the best-interests-of-the-child test, including the nature of the child's relationship with each parent, each parent's willingness to support the child's relationship with the other parent, and any history of family violence.
Child support obligations under the Federal Child Support Guidelines are calculated based on income, not marriage duration. The paying parent's obligation is determined by their gross annual income and the number of children, using the Ontario child support tables. A parent earning $80,000 with one child would pay approximately $746 per month regardless of whether the marriage lasted 6 months or 15 years.
Filing Process for Divorce After a Short Marriage in Ontario
The procedural steps for obtaining a divorce after a short marriage in Ontario are identical to any other divorce proceeding. The total court filing cost is $679, paid in two installments: $224 for the Application for Divorce (Form 8A) and $445 for the Affidavit for Divorce, plus a mandatory $10 federal fee for the Central Registry of Divorce Proceedings.
Step-by-Step Process
- Confirm eligibility: at least 1 spouse has been ordinarily resident in Ontario for 1 year before filing (Divorce Act, s. 3(1))
- Confirm separation: spouses have lived separate and apart for at least 1 year (or establish adultery or cruelty grounds)
- Prepare Form 8A (Application for Divorce) and supporting documents
- File at the Ontario Superior Court of Justice and pay $224 filing fee
- Serve the application on the other spouse (personal service required for first document)
- If uncontested, file the Affidavit for Divorce and pay $445
- A judge reviews the paperwork and issues the Divorce Order (no court appearance required for uncontested cases)
- Wait 31 days for the appeal period to expire
- On day 32, the divorce is final and the Certificate of Divorce can be obtained
An uncontested divorce after a short marriage in Ontario typically takes 4 to 6 months from filing to the Divorce Order. A contested divorce involving disputes over property equalization, spousal support, or parenting arrangements can take 1 to 2 years or longer.
Fee Waivers
Ontario provides fee waivers for individuals who receive Ontario Works, Ontario Disability Support Program (ODSP) benefits, or who meet specific low-income thresholds. If approved, the entire $669 provincial filing fee is waived. The $10 federal registry fee cannot be waived. Applications for fee waivers are filed at the court office with proof of financial need.
Separation Agreements: Essential for Short Marriage Divorces
A separation agreement is particularly important in a divorce after a short marriage in Ontario because it allows both spouses to negotiate property division, spousal support, and parenting arrangements without court intervention. Under Family Law Act, s. 54, a domestic contract is enforceable if it is in writing, signed by both parties, and witnessed. Each spouse should obtain independent legal advice before signing.
In short marriages, a well-drafted separation agreement can address the pro-rata equalization reduction (agreeing to a specific percentage rather than litigating the unconscionability test), the matrimonial home exclusion (negotiating buyout terms or sale proceeds), spousal support waiver or limited-term support, and parenting arrangements and child support. Without a separation agreement, the cost of litigating these issues in court can easily exceed $25,000 to $75,000 per spouse for a contested proceeding in Ontario, which often exceeds the total value of the assets in dispute in a short marriage.
Common Law Relationships vs. Short Marriages in Ontario
Ontario treats common-law relationships differently from marriages when it comes to property division, and this distinction is particularly relevant for short relationships. Married spouses are entitled to equalization of NFP under the Family Law Act, even after a marriage lasting only a few months. Common-law partners in Ontario have no automatic right to property division regardless of how long they lived together. A common-law partner seeking a share of property must bring a claim based on unjust enrichment or constructive trust, which requires proving a direct contribution to the other partner's asset accumulation.
Spousal support rules differ as well. Under the Family Law Act, s. 29, a common-law partner can claim spousal support only if the couple lived together continuously for at least 3 years, or if they have a child together and are in a relationship of some permanence. A married spouse can claim support after any length of marriage, making the legal protections in a short marriage significantly stronger than in a common-law relationship of equivalent duration.
| Factor | Short Marriage | Common-Law (Under 3 Years) |
|---|---|---|
| Property Division | Equalization of NFP (reducible for under 5 years) | No automatic right; must prove unjust enrichment |
| Spousal Support | Available regardless of marriage duration | Available only after 3 years or if child together |
| Matrimonial Home | Special protection; no pre-marriage deduction | No special protection |
| Pension Division | Automatic right to equalization | No automatic right |
| Filing Requirement | Formal divorce required | No formal process needed |
Costs of Divorce After a Short Marriage in Ontario
The total cost of a divorce after a short marriage in Ontario ranges from $679 for a self-represented uncontested divorce to $15,000 to $30,000 for a lawyer-assisted uncontested divorce, and $50,000 to $200,000+ for a fully contested proceeding. These figures include legal fees, court costs, and disbursements. As of March 2026, the Ontario Superior Court filing fees are $679 total. Verify current fees with your local court office.
| Cost Component | Uncontested (Self-Rep) | Uncontested (Lawyer) | Contested |
|---|---|---|---|
| Court Filing Fees | $679 | $679 | $679+ |
| Legal Fees | $0 | $2,500 to $5,000 | $25,000 to $150,000+ |
| Mediation | N/A | $2,000 to $5,000 | $3,000 to $8,000 |
| Financial Disclosure | Minimal | $500 to $2,000 | $2,000 to $10,000 |
| Total Range | $679 to $1,000 | $5,000 to $15,000 | $50,000 to $200,000+ |
For quick marriage divorce scenarios where both spouses agree on all terms, an online divorce service or paralegal can prepare the documents for $500 to $1,500. Ontario permits licensed paralegals to assist with certain family law matters, though they cannot represent clients in Superior Court proceedings.
Frequently Asked Questions
Can I get a divorce in Ontario if I was married less than a year?
Yes, Ontario has no minimum marriage duration to file for divorce. A spouse married for 1 day can file under the Divorce Act, s. 8(2). The only timing requirement is the 1-year separation period (or proof of adultery or cruelty). Court filing fees total $679 regardless of marriage length.
How is property divided in a short marriage divorce in Ontario?
Ontario uses equalization of net family property under the Family Law Act. For marriages under 5 years, courts may reduce the equalization payment pro-rata under s. 5(6)(d). A 2-year marriage may result in only 40% (2/5) of the standard equalization amount, though this requires proving the full amount would be unconscionable.
Do I have to pay spousal support after a 1-year marriage in Ontario?
Spousal support after a 1-year marriage is typically minimal. Under the Spousal Support Advisory Guidelines, the without-child formula produces support of 1.5% to 2% of the income difference per year of marriage, lasting 6 to 12 months. Courts frequently deny support entirely in brief marriages where both spouses are self-sufficient.
What happens to the matrimonial home in a short marriage?
The matrimonial home receives special treatment under Family Law Act, s. 4(1). Even in a short marriage, the pre-marriage value of the home cannot be deducted from the owning spouse's net family property. If one spouse owned a $600,000 home before a 1-year marriage, the full value is included in the equalization calculation with no deduction.
Can I get an annulment instead of a divorce for a short marriage in Ontario?
Annulments in Ontario are granted only in limited circumstances: bigamy, non-consummation, lack of mental capacity, underage marriage, or consent obtained by fraud or duress. Simply having a brief marriage is not grounds for annulment. Most short marriage divorces proceed through the standard 1-year separation and divorce process.
How long does a divorce take after a short marriage in Ontario?
An uncontested divorce after a short marriage in Ontario takes 4 to 6 months from filing to the Divorce Order, plus 31 days for the appeal period. The total timeline from separation to final divorce is approximately 16 to 18 months (12 months separation + 4 to 6 months processing). Contested proceedings take 1 to 2 years beyond the separation period.
Is a prenuptial agreement enforceable in a short marriage divorce?
Ontario courts generally enforce marriage contracts (prenuptial agreements) under Family Law Act, s. 52, provided both spouses received independent legal advice, made full financial disclosure, and the agreement was not unconscionable when signed. In short marriages, prenuptial agreements are particularly effective because less time has passed for circumstances to change significantly.
What if my spouse refuses to agree to the divorce?
Ontario grants no-fault divorce after 1 year of separation under Divorce Act, s. 8(2)(a) regardless of the other spouse's consent. If your spouse does not respond to the Application for Divorce within 30 days of being served, you can proceed with an uncontested divorce by default. The court filing fee remains $679 and the process takes approximately 4 to 6 months.
Are common-law partners treated the same as married spouses in short relationships?
No. Ontario treats married spouses and common-law partners very differently for property division. Married spouses in a 6-month marriage have automatic equalization rights under the Family Law Act. Common-law partners have no automatic property rights regardless of relationship length and must prove unjust enrichment. Spousal support for common-law partners requires 3 years of cohabitation or a child together.
Can I recover wedding costs or gifts if we divorce after a short marriage?
Ontario courts do not order reimbursement of wedding expenses in a divorce proceeding. Wedding gifts given to both spouses are treated as jointly owned property and divided during equalization. Gifts given specifically to one spouse by a third party (such as a parent's gift to only their child) are excluded from net family property under Family Law Act, s. 4(2), provided the gift was not the matrimonial home.
