Key takeaways
  • In an equalization application, each party must give a sworn statement of their property and debts, and a party who finds a served document is incorrect must promptly serve the corrected information.
  • A court can order a party, and in some cases a non-party, to produce documents or be questioned under oath.
  • A court may set aside a domestic contract, such as a separation agreement, if significant assets or debts were not disclosed when it was made.

It is unsettling to suspect that your spouse is not telling the whole truth about money. Maybe accounts have gone quiet, a business seems to earn less than it did, or large transfers appeared shortly before separation. The good news is that Ontario's process is built on mandatory disclosure.

This article walks through the disclosure you can expect, the tools available when it is missing or doubtful, and the practical steps to take. It is general information, and a lawyer can help you apply it to your facts.

Disclosure is required, not optional

In an equalization application, each party must serve on the other and file with the court a sworn statement of their property, debts and other liabilities. It must cover the date of marriage, the valuation date and the date of the statement, along with claimed deductions and exclusions and certain disposals of property.

Under the Family Law Rules, a party making a property claim must serve and file a financial statement with the claim, which for property claims is Form 13.1. The responding party must do the same within the time for its answer or response.

Supporting documents follow. Within 30 days after the financial statement is due, a party to a Part I property claim must serve supporting documents, including statements for accounts and investments issued closest to the valuation date.

Checking the disclosure you receive

Before trial or a settlement conference, each party to a Part I property claim must serve and file a net family property statement, Form 13B. For a settlement conference it is due six days before for the requesting party and four days before for the other party, and for trial it is due 30 days before the earlier of the trial start and the trial sitting.

A party who discovers that a document served under Rule 13 is incorrect must promptly serve the corrected information. When you review your spouse's papers, look for gaps.

Court tools when disclosure is missing or doubtful

SituationWhat the court may do
A required document was not served or filedOrder the party to do so on motion, and must also order them to pay costs
A party does not obey an orderMake any order it considers necessary, including costs, a fine, dismissing a claim, striking out documents, or barring use of undisclosed documents
A document is held by someone who is not a partyOrder the non-party to produce it if it would be unfair to go on without it
Questioning is neededOrder a party or non-party to be questioned under oath
Assets may be run down while the case proceedsMake interim or final orders restraining depletion of property

Valuing a business or other complex property usually needs outside valuation evidence, because no statutory formula exists for it.

Hiding assets can affect the result

If property was run down on purpose, a court may consider intentional or reckless depletion and undisclosed debts when deciding whether an equal split would be unconscionable, though that bar is high. If you already signed a separation agreement and later find out something was concealed, a court may set aside a domestic contract where a party failed to disclose significant assets, debts or other liabilities that existed when it was made.

If a dispute is about who owns a particular asset, a person may apply to court to decide ownership or possession between them and their spouse. Where property is held in both names as joint tenants, it is presumed to be jointly owned, and money on deposit in both names is treated as held in joint tenancy.

What to do next

Frequently asked questions

What if my spouse refuses to provide financial documents?

The court may, on motion, order a party who has not served or filed a required disclosure document to do so, and it must also order that party to pay costs. If an order is ignored, the court can make further orders such as barring use of undisclosed documents.

Can the court get documents from a bank or someone else?

The court may order a non-party to produce a document, and the test is whether it would be unfair to go on with the case without it. It may also order a party or non-party to be questioned under oath.

Can I stop my spouse from spending or moving assets while the case goes on?

In an equalization or title application, the court may make interim or final orders restraining the depletion of a spouse's property. Whether one is appropriate depends on the facts.

What if I find out about hidden assets after we signed an agreement?

A court may set aside a domestic contract, such as a separation agreement, if a party failed to disclose significant assets, debts or other liabilities that existed when it was made. You should get legal advice promptly, since time limits can apply.
