The Role of Financial Disclosure in Family Law Proceedings

When navigating a separation or divorce, financial disclosure plays a critical role in ensuring fairness and transparency. In Ontario family law, disclosure is more than a formality; it is extremely important for negotiating property division, support, separation agreements, and more. Without complete and accurate disclosure, neither lawyers nor the courts can make informed decisions, leaving both parties vulnerable to disputes and unfair outcomes.

Below, we break down what financial disclosure means, why it matters, and how family lawyers can help you navigate the often complex process. If you have questions about financial disclosure, schedule a consultation with our legal team at Gelman & Associates today.

What is Financial Disclosure in Ontario Family Law?

Financial disclosure is essential to any family law proceeding that involves claims for property and/or support. Without it, no lawyer can properly advise you of your rights or entitlements under Ontario law.

Making a complete and accurate financial disclosure is the very first step in most family law matters. It typically begins with filling out a Form 13 or 13.1 financial statement, which outlines all assets and liabilities in your name.

  • Unmarried individuals or those making only support claims must disclose their current assets and liabilities, provide income tax information for the preceding three years, and supply current income details.
  • Married individuals who are seeking property claims must disclose their assets and liabilities at three points in time: their date of marriage, their date of separation, and the present day. They must also provide income tax information for the preceding three years and current income details.

In addition, parties must put together a supporting disclosure brief with backup documents to confirm that all the figures they have provided in their financial statement are accurate. Income disclosure and a list of current expenses are also generally required.

While the process of financial disclosure can take a considerable amount of time, it is necessary to make informed, legally-binding decisions about property division, spousal support, and other important family law matters.

Your Legal Obligations and the Impact of Financial Disclosure on Divorce Settlements

Financial disclosure is not an optional process. It is a legal requirement in Ontario family law cases.

  • For Agreements Negotiated Outside of Court: Lawyers often attach each party’s financial disclosures to their finalized Agreement. It is important that complete, accurate statements are made, as this will ensure that any Agreements entered into are legally binding and cannot be challenged later.
  • For Litigated Agreements: Complete and accurate financial disclosure is required to commence with any proceeding that deals with claims for property and/or support. The court also requires that litigants keep their financial statements up to date by filing updated disclosures before each court appearance. If you do not complete the financial disclosure process, your materials may be rejected by the court, and your case may be delayed.

Accurate disclosure can have a direct impact on settlement outcomes during divorces. During the equalization of property, it may determine who owes whom an equalization payment. In cases of child support and spousal support, it informs both the amount and, in spousal support matters, the duration of payments. As a result, full and honest disclosure gives both parties the confidence that their settlement is fair and legally sound.

What Are the Risks of Incomplete or False Financial Disclosure?

If the financial disclosure process is not properly completed, the outcome of the case is likely to be significantly impacted. Some serious consequences include:

  • Incorrect Outcomes: Incomplete or incorrect financial statements may lead to inaccurate support calculations or property division.
  • Overturned Agreements: In cases where the parties have entered into an Agreement relying on false financial statements, there will be grounds to argue that the Agreement should be set aside. This is because financial disclosure is a critical component in negotiating settlement terms.
  • Delays and Added Costs: Courts can reject incomplete or inaccurate materials, which can prolong your legal matter and increase the amount of legal fees you accumulate over time.

Because disclosure is the foundation of the entire family law process, even small omissions can create significant legal and financial problems down the road. If you have questions about the financial disclosure process, you should contact a family law lawyer as soon as possible.

How to Ensure Full and Accurate Financial Disclosure in Ontario

To ensure that you are making a full and accurate financial disclosure, you must engage in proper planning and diligence. Some key steps include:

  1. Gathering Financial Records: It may be best to start by visiting all banking institutions that you deal with and requesting your banking portfolio for all accounts that existed at the relevant dates. This portfolio will show all existing accounts on one sheet of paper and may make it easier to ensure that you’re not missing anything important.
  2. Including all Property and Valuables: Your financial statement will also ask you to disclose your holdings in real estate, vehicles, pensions, and other items of value.
  3. Disclosing International Assets: Complete financial disclosure does not only refer to your assets and liabilities in Canada. If you have property, bank accounts, or other items of worth outside of the country, you have an obligation to disclose their value.

Leaving out assets, whether intentional or not, can compromise your family law case and any Agreements you reach. It is important that you don’t leave anything out. By taking the steps outlined above, you can help ensure that the disclosure process is complete, accurate, and less likely to be challenged at a later date.

Frequently Asked Questions - divorce & separation

If you are litigating your matter, social media posts made by your spouse or partner may be relevant, especially if they contradict what your spouse is claiming in his or her pleadings.

For example, if a spouse is claiming financial hardship, a Facebook post that shows that spouse going on an expensive trip or posing with an expensive car can undermine such claim  and, potentially affect that party’s credibility in court if presented as evidence on a motion or at trial.

Further to photograph-based posts, statements that are made on social media by one party can be relevant if said posts (i) are related to the litigation, to issues of parenting  and/or (b) they contradict statements that were made by the party in his or her pleadings. For example, if a party who is attempting to establish that he or she is an appropriate custodial parent, then recent social media posts about extensive partying and drug use made by that party may be relevant in court, as they may speak to that party’s fitness when it comes to appropriate supervision of a child in his or her care.

The Ontario Attorney General’s website estimates that divorce proceedings can take approximately four to six months to complete, provided that all documents have been appropriately accomplished and submitted on time.

No. The law does not favour mothers over fathers in divorce proceedings. The judge will base his decision on the evidence laid out by both parties.

The main distinction between divorce and separation is that divorce ends your marriage formally. You and your partner are no longer married.
If you’re separated, you’re still legally married to each other even if you receive a formal separation, and you must continue to record that you’re married on documents.

No. You are not required to get a lawyer for a divorce. However, it is best if you retain one to ensure that you fully understand all your rights and obligations.

A joint divorce application occurs when you and your spouse both agree to a divorce and on all other family law matters such as parenting, spousal support, or division of property.

Yes, it is different. Family law problems are addressed mainly by provincial laws in Ontario. Divorce law, on the other hand, is controlled by federal legislation in the form of the Divorce Act, which applies uniformly across the country.

Divorce can be a difficult decision to make, especially if you’re unsure if your partner will sign the petition. However, a divorce does not require your partner’s consent. Although it may be a long process if your partner doesn’t comply, they will not be able to stop you indefinitely.
