Ontario law has no special rule for the half-of-assets clause. A court reads it like any term of a domestic contract: its effect depends on the exact wording of your marriage certificate and what you both intended when you signed, and it does not automatically replace Ontario's division of property. Conditions about who keeps the children are not enforceable in Ontario.
This guide covers Ontario and Canadian law only, not Iranian law. If you want to know what the clause means in Iran, ask a lawyer in Iran.
Many women have heard that the half-of-assets clause (shart-e tansif) gives them "half of everything", and many men worry that the same clause will be enforced against them in Canada. In Ontario, both beliefs need correcting. In the Act, a "domestic contract" includes a marriage contract and a separation agreement (s. 51), and an Iranian marriage certificate can count as one if it meets the requirements; the general rules are on our page on domestic contracts in Ontario.
How are the conditions in an Iranian marriage certificate examined in an Ontario separation, step by step?
The half-of-assets clause usually comes up in the same case as the divorce, support and property division. The order of work is usually this:
- Translate the certificate. The Ministry of the Attorney General's guide says a marriage certificate from outside Canada that is not in English must be translated by a certified translator. Translate every page, including the page of conditions.
- Which conditions were signed? Under Ontario's Family Law Act, a domestic contract must be in writing, signed by the parties and witnessed (s. 55(1)); for a contract made in Iran, s. 58 also matters.
- The right court. The property part of the Act leaves the Ontario Court of Justice out of its definition of "court" (s. 4(1)), so this claim goes to the Superior Court of Justice. In Toronto, see which Toronto family court handles your case.
- The financial statement. In a property claim, the financial statement is Form 13.1 (Family Law Rules, r. 13(1.2)). Take care that the mahr and a half-of-assets claim are not counted twice; how to complete it is in which financial statement to file.
- The court's decision. The court answers three questions separately: is the condition valid, what does it mean, and should it be set aside?
What does an Ontario court do with a contract signed in Iran?
Under s. 58 of the Family Law Act, the manner and formalities of making a domestic contract, its essential validity and its effect are governed by the proper law of the contract, with three exceptions. First, a contract governed by the law of another place is also valid and enforceable in Ontario if it was made in accordance with Ontario's internal law. Second, the Ontario court's power to set aside a contract, and to set aside a support provision or a waiver of support (s. 33(4)), applies to these contracts too. Third, a term in a marriage contract about decision-making responsibility or parenting time is not enforceable in Ontario.
The Court of Appeal for Ontario explained how an Iranian marriage contract is read in Bakhshi v. Hosseinzadeh, 2017 ONCA 838. The couple married in Iran on May 18, 1995, and later immigrated to Canada; their contract required the husband to pay 230 gold coins on the wife's prompt request (para. 2). The court said the outcome depends on the parties' objective intentions, found from the wording of the contract read as a whole and in light of its factual matrix, and that the court enforces only undertakings that meet the requirements of a civil domestic contract (para. 22). The same reasoning about the mahr is set out in detail in whether a mahr is enforceable in Ontario.
Another point from that case matters for the half-of-assets clause. The couple's contract had a clause giving the wife a power of attorney to seek a divorce if the husband breached one of the listed behavioural requirements. Relying in part on that clause, the court concluded that when they signed in Iran the couple contemplated their continued life in Iran, and that there was no basis to infer they contemplated their obligations under Ontario's Family Law Act (para. 33).
How does the half-of-assets clause relate to equalization in Ontario?
In equalization, each spouse calculates their net family property, and the spouse whose net family property is lower is entitled to half the difference (Family Law Act, s. 5(1)). That right does not depend on who asked for the separation; only the equitable considerations in s. 5(6) can change it (s. 5(7)). The details are on our page on property division in Ontario.
Which country's law governs the property rights arising from the marriage depends on where both spouses last had a common habitual residence (s. 15). For a couple who last lived together in Ontario, that law is Ontario's.
This is where the half-of-assets clause comes in. The Act says a domestic contract dealing with a matter also dealt with in the Act prevails, unless the Act provides otherwise (s. 2(10)). And one way property is left out of net family property is if the spouses agreed by a domestic contract that it is not to be included (s. 4(2), para. 6). So the court asks: was the clause meant to replace Ontario's division, to add to it, or neither? The law has no ready-made answer. On the reasoning in Bakhshi, a court may not accept that a couple who signed intending to live in Iran made an agreement about dividing property under Ontario law.
A clause that is not a valid domestic contract is not entirely without effect. "A written agreement between the spouses that is not a domestic contract" is one of the factors a court can consider, but only if it finds that equalizing net family property would be unconscionable (s. 5(6)(g)).
What if the clause depends on who asked for the divorce, or who was at fault?
The wording of the half-of-assets clause in your certificate may refer to who asked for the divorce and whether one spouse's conduct caused it. In Ontario, either spouse can apply for a divorce on the ground of breakdown of the marriage (Divorce Act, s. 8(1)), and one way to show breakdown is that the spouses have lived separate and apart for at least one year (s. 8(2)(a)). So an Ontario case does not usually turn on who was to blame.
In Bakhshi, the husband argued that a fault-based agreement should not be enforced because it would be contrary to Ontario's no-fault family law regime (para. 12). The court did not rule on that argument; it upheld the trial judge's reading that the two main clauses were separately executed and that the list of behavioural requirements related to the wife's power of attorney to seek a divorce (paras. 25 and 26). So the sources on this page give no clear answer to that question, and if your certificate has such a condition, it should be reviewed with a lawyer before you decide anything.
What happens to the other conditions in the certificate?
Marriage certificates differ, and what matters is the wording of your own. The table below sets common conditions beside the Ontario rule.
| What the certificate may say | Ontario rule | Source |
|---|---|---|
| A mahr (for example, gold coins) | May be enforceable if in writing, signed and witnessed; in net family property it counts as the husband's debt and the wife's asset unless the wording excludes it | FLA, ss. 55(1) and 4(2), para. 6; Bakhshi, paras. 34, 42 and 43 |
| Half-of-assets clause | Read like any contract term; its effect depends on the wording and the intention at signing; it does not automatically replace Ontario's division | FLA, ss. 2(10), 5 and 58; Bakhshi, paras. 22 and 33 |
| The wife's power of attorney to seek a divorce if conditions are breached | Not needed for a divorce in Ontario; either spouse can apply | Divorce Act, s. 8 |
| A condition about who the children stay with | Not enforceable in Ontario; the court decides on the child's best interests | FLA, s. 58(c) |
| A condition about the children's education or moral training | A marriage contract may deal with it, but the court may disregard it if that is in the child's best interests | FLA, ss. 52(1)(c) and 56(1) |
| Any condition about support or waiving support | The court may set it aside, for example if it results in unconscionable circumstances | FLA, ss. 33(4) and 58(b) |

What could lead a court to set a condition aside?
Under s. 56(4), a court may set aside a domestic contract or a term in it if a party failed to disclose significant assets, or significant debts or other liabilities, that existed when it was made; if a party did not understand its nature or consequences; or otherwise in accordance with the law of contract. That power applies despite any agreement to the contrary (s. 56(7)) and to contracts governed by foreign law (s. 58(b)).
If you are being asked to give up the mahr or the half-of-assets clause in a separation agreement, get advice before you sign; the steps of a divorce by agreement are in how an uncontested or joint divorce works in Ontario.
What changes the answer?
- The exact wording. The court reads the contract as a whole and in light of the circumstances when it was signed (Bakhshi, para. 22).
- Signatures and witnesses. A domestic contract must be in writing, signed and witnessed (FLA, s. 55(1)), or valid under its own proper law (s. 58).
- Where you last lived together. The law of the last common habitual residence governs property rights arising from the marriage (s. 15).
- A later agreement. A contract signed later may have changed what happens to the condition, if it is in writing, signed and witnessed (s. 55(1)).
- Disclosure and understanding. Not disclosing a significant asset or debt, or not understanding the contract, opens the way to setting it aside (s. 56(4)).
- Children. Terms about decision-making responsibility and parenting time are not enforced in Ontario (s. 58(c)).
A worked example
For example, imagine Maryam and Ali, who married in Shiraz in 2010. Their marriage certificate sets a mahr in gold coins, and the printed half-of-assets clause appears next to Ali's signature. They have lived in Richmond Hill since 2014 and separated in 2025. Maryam thinks that, on top of her share of the property division, she is owed half of everything; Ali thinks that because Maryam asked for the separation, no condition helps her. Because their last common habitual residence was Ontario, equalization follows Ontario law and does not depend on who asked for the separation. The mahr, unless its wording says otherwise, goes into the calculation and may also be claimed separately. On the half-of-assets clause, the court looks at the certified translation and the evidence of what they intended in 2010. Because the family lives in York Region, their property claim is heard at the family court in Newmarket. This is a hypothetical example, not a prediction of the result of any case.
What mistakes do people make?
- Assuming the clause means half of everything, on top of Ontario's division. Whether the two add together depends on the wording and the evidence.
- Assuming that if the wife asked for the separation, she has no share in Ontario. Equalization does not depend on who asked for the separation (FLA, s. 5(7)).
- Relying on an informal translation or a verbal summary of the certificate. The court reads the text.
- Signing a separation agreement without reviewing the certificate's conditions. A new agreement may take away rights the certificate gave you.
- Counting on a custody condition. These terms are not enforced in Ontario.
- Waiting until the time limit has passed. An equalization claim must be brought before the earlier of six years after separation or two years after the divorce (s. 7(3)); see the deadlines in an Ontario family case.
What to do this week
- Find the original certificate or a copy, and take clear photos of every page, including the conditions page.
- List which conditions were signed next to and which were not.
- Order a full certified translation of the certificate, not just the first page.
- Write down where you lived when you married and where you intended to live; this may matter in interpreting the clause.
- Note your separation date and work out the time limit for a property claim.
- Gather your financial documents for the financial statement, and go through the first-week separation checklist.
Frequently asked questions
Does it matter if we signed the marriage certificate after immigrating, in Ontario?
It may. The reasoning in Bakhshi rested on the couple signing with life in Iran in mind; for a couple signing in Toronto, the evidence of their intentions is different. If you are not yet married, two people who intend to marry can make a marriage contract in Ontario that deals with property, support and other matters directly (FLA, s. 52(1)).
Does the half-of-assets clause apply to the matrimonial home in Ontario?
Whatever the clause says, a term in a marriage contract that limits a spouse's rights over the matrimonial home under Part II of the Act is unenforceable (FLA, s. 52(2)). The home's value also counts in net family property even if it was bought before the marriage (s. 4(1)), unless a valid domestic contract has excluded it (s. 4(2), para. 6).
Does the clause cover our property in Iran?
Property in Iran also counts in net family property, and in Bakhshi itself, real property in Iran formed part of the calculation (para. 38). Our page on whether property in Iran counts in Ontario explains how it is valued and disclosed.
Can the court deal with property if we are not yet divorced?
Yes. The right to equalization arises once the spouses are separated and there is no reasonable prospect that they will resume living together, even before a divorce (FLA, s. 5(1)). If you married in Iran, the divorce itself is explained in married in Iran: can you divorce in Ontario.
Can a religious leader or a family elder decide on this clause?
You can take advice from anyone. But a decision by a third person in a process that is not conducted exclusively under the law of Ontario or another Canadian jurisdiction is not a family arbitration and has no legal effect (FLA, s. 59.2). How a valid family arbitration works is explained in whether a family arbitration award is binding in Ontario.
Is the mahr paid separately from equalization?
In Bakhshi, the mahr was included in the equalization calculation as a demand obligation, and the court said it still had to be actually paid: collecting it is a debt collection issue, not an equalization issue (para. 43).
