The valuation date is the single day on which each spouse's property and debts are measured for equalization. Under section 4(1) of Ontario's Family Law Act it is the earliest of five events, and for most couples it is the day they separated with no reasonable prospect of living together again. Values are taken at close of business on that day.
How is the valuation date set in Ontario?
Every number in an equalization claim is pinned to one date. Bank balances, house values, pension values and debts are all measured on that day, so choosing the date is one of the first decisions in any property case. For the wider picture of property claims, see our property division page.
The Family Law Act defines the valuation date as the earliest of these dates:
- The date the spouses separate and there is no reasonable prospect that they will resume cohabitation.
- The date a divorce is granted.
- The date the marriage is declared a nullity.
- The date one spouse starts an application for improvident depletion under section 5(3), if that application is later granted.
- The day before the date on which one spouse dies, leaving the other surviving.
Because the law takes the earliest date that applies, a couple who separated in 2023 and divorced in 2025 has a 2023 valuation date. The divorce date only becomes the valuation date in the unusual case where no earlier date applies.
Once the date is fixed, section 4(4) says each value is calculated as of close of business on that day. That date then feeds straight into the calculation of net family property. From there it shapes the equalization payment described in our guide to how property is divided in Ontario.
| Event | When it is usually the valuation date | Where the rule is |
|---|---|---|
| Separation with no reasonable prospect of reconciling | Most separations | Family Law Act, s. 4(1), para. 1 |
| Divorce granted | Rarely, only if no earlier date applies | s. 4(1), para. 2 |
| Marriage declared a nullity | Annulment cases | s. 4(1), para. 3 |
| Improvident depletion application started | Spouses still living together, one is draining assets | s. 4(1), para. 4; s. 5(3) |
| Day before a spouse's death | A spouse dies while the couple is still together | s. 4(1), para. 5; s. 5(2) |
Why is the separation date so often disputed?
Two things make the separation date a common battleground. First, values move. A stock portfolio, a business, a bonus paid in a particular month or a sharp change in the housing market can shift a spouse's figure by thousands of dollars within a few weeks. Second, the test in the Act has two parts, and both must be met: the spouses have separated, and there is no reasonable prospect that they will resume cohabitation.
"Cohabit" is defined in section 1(1) of the Act as living together in a conjugal relationship. The focus is on the relationship, not only on the address. A couple can stay under one roof for financial reasons after the relationship has ended, and a couple can live in different cities while the marriage carries on. That is why the day someone moved out is evidence of the date, but not automatically the date itself.
The second part looks at whether there was a realistic chance of getting back together. A couple who spent a few weeks apart, went to counselling and then resumed their married life would have a hard time showing that point was reached. A couple who have told family and friends, divided their accounts and stopped spending time together as a couple are much closer to it.
Note one difference from divorce law. For a divorce, the federal Divorce Act lets spouses resume living together for up to 90 days, with reconciliation as the main purpose, without breaking the one-year separation period (Divorce Act, s. 8(3)(b)(ii)). That rule is about the divorce clock. The Family Law Act has no matching 90-day rule for the valuation date, so a reconciliation attempt is weighed on its own facts.
What evidence helps prove the date?
If the spouses cannot agree, a judge decides the date on the evidence. The kinds of records people commonly gather include:
- a lease, purchase agreement or change-of-address notice showing when one spouse moved;
- texts, emails or letters where either spouse said the marriage was over;
- bank records showing when joint accounts were closed or split, or when pay started going to a new account;
- a letter from a lawyer, or the date a mediator was first contacted;
- changes in sleeping arrangements, shared meals, holidays and family events;
- how each spouse described their marital status to employers, insurers or government offices.
No single item settles the question. The more the records point to the same day, the stronger the case for that date.
What changes the answer
- A spouse dies. If the couple was still together, the valuation date is the day before the death (s. 4(1), para. 5), and the survivor must choose between the will and equalization within six months (s. 6(10)). If the couple had already separated, the earlier separation date stays the valuation date because it comes first. Our page on death and equalization covers both situations.
- Depletion during the marriage. A spouse who fears the other will improvidently deplete their property can apply under section 5(3) while still living together. If the application is granted, the date it was started becomes the valuation date.
- Property received after the valuation date. Net family property counts only property owned on the valuation date. An inheritance received a month after separation is simply not in the calculation, while one received a month before is counted unless it qualifies as excluded property under section 4(2).
- The matrimonial home. Section 18(1) defines the matrimonial home by reference to the family residence at the time of separation, so the separation date also settles which property gets the special home rules.
- Pensions. The family law value of a pension is measured from the marriage date to the valuation date (s. 4(1), clause (c), and s. 10.1). See our page on pensions on separation.
- Businesses. A business interest is valued on the valuation date, and rule 13(3.3) of the Family Law Rules requires financial statements and tax returns for the three years before it. Our page on a business owned by one spouse explains why.
A worked example
For example, imagine a hypothetical couple, Sam and Taylor. Sam says the marriage ended in January, when Taylor moved into the basement and they stopped sharing meals. Taylor says it ended in September, when Sam signed a lease elsewhere. Between those months, Sam's investment account grew from $200,000 to $230,000, and nothing else changed much. If January is the valuation date, the account counts at $200,000. If September is the date, it counts at $230,000, which raises Sam's net family property by $30,000. Since the payment is half the difference between the spouses' figures, the date choice moves the equalization payment by $15,000 (half of $30,000). Whether the extra growth is shared depends on the evidence about when the relationship actually ended, not on who moved out first.
Common mistakes around the valuation date
- Assuming the moving-out day is automatically the date. It is strong evidence, but the test is about the relationship and the prospect of reconciliation.
- Mixing up the divorce rule with the property rule. The one-year separation needed before a divorce is granted (Divorce Act, s. 8(2)(a)) and the 90-day reconciliation allowance are divorce rules. They do not set the valuation date.
- Sending mixed messages. Booking a family holiday, filing documents as a couple or telling a lender you are together after you say you separated can be used to argue for a different date.
- Getting statements for only one date. If the date is disputed, collect records for each date in play, so the numbers are ready whichever date is chosen.
- Forgetting the clock. The same separation date starts the six-year limit for an equalization claim in section 7(3)(b). Our page on equalization deadlines explains how the limits work together.
What to do this week
- Write a short timeline of the end of the relationship: key conversations, moves, account changes and holidays, with dates.
- Save texts, emails and letters that mention separating. Do not delete anything, even if it looks unhelpful.
- Request account, investment and debt statements as close as possible to each date that might be argued.
- Ask your pension plan administrator about applying for a family law value once the date is agreed or decided.
- If either of you owns a business, set aside the last three years of financial statements and tax returns.
- Avoid new joint commitments, such as joint loans or joint purchases, until the date is settled.
- Book a free consultation to test your date against the evidence before you commit to it in writing.
Frequently asked questions
Can we be separated while still living in the same house?
Yes, it is possible. The Act defines cohabiting as living together in a conjugal relationship (s. 1(1)), so the question is whether the relationship has ended, not only whether you share an address. Evidence about separate rooms, finances and social life matters a great deal in these cases.
Does a short reconciliation reset the valuation date?
It depends on the facts. If the attempt showed there was still a reasonable prospect of resuming the marriage, the separation date may move to when the attempt failed. The 90-day rule in the Divorce Act applies to the divorce waiting period, not to the property valuation date.
Do we need to agree on the date before anything else happens?
No. Many couples agree on a date early because it saves cost. Others exchange numbers for two dates and negotiate. Support does not have to wait for the property dispute: in a divorce case, for example, a court can make an interim spousal support order while the main claim is pending (Divorce Act, s. 15.2(2)). Our page on interim support explains how that works.
Is the valuation date the same as the date of separation for a divorce?
Often the same day matters for both, but the tests serve different purposes. For divorce, the question is whether you lived separate and apart for at least one year before the court decides (Divorce Act, s. 8(2)(a)). For property, it is the earliest of the five events in section 4(1).
Does property bought after separation count?
No. Net family property counts only what a spouse owns and owes on the valuation date (s. 4(1)). A car bought or a debt run up after that day is outside the calculation, although it may still matter for support.
What time of day is used?
Close of business on the valuation date (s. 4(4)). In practice, the statement issued closest to that date for each account is the starting point, which is what rule 13(3.3) of the Family Law Rules asks each spouse to produce.
