When we talk about very short marriages in Ontario, we are usually looking at how the property division rules under the Family Law Act operate — and when they might produce a result that feels disproportionate.
Under Ontario law, married spouses do not literally split each asset in half. Instead, we use a system called “equalization.” Equalization means each spouse calculates their “net family property,” which is essentially the value of what they owned on the date of separation, minus debts and certain deductions. The spouse with the higher net worth pays the other spouse half of the difference. It is a financial balancing payment, not a transfer of specific property.
The matrimonial home is treated differently from all other property. A “matrimonial home” simply means the home the spouses ordinarily lived in together at separation. Even if one spouse owned the home before the marriage, they cannot deduct its value as of the date of marriage if it was the matrimonial home when they separated. In practical terms, that means the full value of the home is included in their net family property.
In a long marriage, that often feels fair. In a marriage lasting only a few months, it can feel severe.
Extremely Short Marriages and “Unconscionability”
Section 5(6) of the Family Law Act allows a court to change the usual equalization result if it would be “unconscionable.” That word has a very specific legal meaning. It does not simply mean unfair. It means a result so one-sided or extreme that it would shock the conscience of the court.
In extremely short marriages, courts sometimes consider whether forcing equalization of a pre-owned matrimonial home would cross that line. For example, if someone owned a home outright for many years, married briefly, and separated shortly after, equalization could require them to share a significant portion of its value with someone who contributed little to it. The question becomes whether applying the formula strictly would produce an outcome that is truly shocking.
Ontario courts set a high bar. A marriage lasting one year may still not qualify as “extremely short.” We are often talking about marriages measured in months, not years.
What Courts Actually Examine
When deciding whether equalization would be unconscionable, courts look at the full picture. They consider:
- The length of the marriage and whether it functioned more like a brief cohabitation
- Whether the non-owning spouse contributed financially or otherwise to the home
- Whether the spouses combined finances or kept everything separate
- Whether equalization would create a windfall — meaning a large financial gain disconnected from the short relationship
- Whether any other statutory factors make the result excessively disproportionate
The court is not focused on whether one spouse now regrets marrying. It looks at whether the financial result is fundamentally out of step with the reality of the relationship.
Important Limits and Exceptions
Even in short marriages, equalization will usually apply. If the non-owning spouse moved into the home, treated it as their family residence, and reorganized their life around the marriage, the law recognizes that commitment.
Also, if the home increased in value during the marriage due to market forces, that increase is typically shared through equalization — unless the unconscionability threshold is clearly met.
The Practical Reality
Arguments based on a “short marriage” are not easy to win. The equalization system was designed to create predictability. Courts only step in where applying the formula strictly would produce a result that is dramatically unfair in a legal sense.
If you are facing this issue, the details matter: the exact dates of cohabitation and marriage, the value of the home at each stage, the level of financial integration, and the overall economic impact. The difference between a result that feels harsh and one that is legally “unconscionable” can determine the outcome entirely.
New to Child Support Law? Here is a summary of the basics that you need to know.
Child support is a critical aspect of family law that ensures the financial needs of children are met following parental separation or divorce. In Ontario, child support laws are designed to protect the best interests of the child, ensuring they receive adequate financial resources for their upbringing.
Understanding Child Support in Ontario
Child support is a critical aspect of family law that ensures the financial needs of children are met following parental separation or divorce. In Ontario, child support laws are designed to protect the best interests of the child, ensuring they receive adequate financial resources for their upbringing.
What is Child Support?
Child support refers to the ongoing payments made by one parent to another after a separation or divorce to assist with the costs associated with raising their children. It covers expenses such as food, clothing, education, and other necessities required for a child’s well-being.
Purpose of Child Support
The primary purpose of child support is to provide financial stability for children when parents separate. It aims to ensure that children’s living standards remain consistent and that they have access to essential resources necessary for healthy development. The legal obligation rests on both parents; however, it often falls on the non-custodial parent (the parent who spends less time with the child) to make these payments.
What is Table Child Support?
Ontario utilizes a standardized federal guideline known as “Table Amounts” for calculating child support payments. These guidelines help ensure consistency across different cases while considering various factors like:
- Income Level: Both parents’ gross annual incomes, if both have the children more than 40% of the time. Otherwise, the income of the person who has the children less than 40% of the time.
- Number of Children: The number of children owed support.
- Custody Arrangement: Whether both parents have roughly equal parenting time.
- Special Considerations: For example, whether, through no fault of their own, a parent has unusually high costs to see the children (i.e., has to fly in for visits).
How is Child Support Calculated?
To calculate table child support in Ontario:
1. Determine Parental Income: Each parent’s gross annual income should be assessed using recent tax returns.
2. Referencing Table Amounts: Use the Federal Child Support Guidelines tables available online, which list monthly payment amounts based on combined parental incomes and the number of children. If both parents have more than 40% of parenting time, the parent with the larger child support amount would subtract the other parent’s child support and pay the other parent the difference.
