Interim costs and disbursements are court-ordered payments that allow the financially weaker party in a family law case to fund legal representation and necessary expenses during litigation—not just at the end. They're designed to level the playing field when one spouse controls the resources. Courts apply strict tests (the "Okanagan Test") focusing on financial need, the other party's ability to pay, and whether denial would prevent a fair hearing. Common scenarios include high-conflict custody disputes, complex property valuations, or cases involving hidden assets. Bottom line: If you can't afford to fight for what's fair, interim costs may be your lifeline.

Introduction

Let's face it—divorce or separation in Ontario isn't just emotionally taxing; it can also leave people staring down the barrel of significant legal costs before they even get their day in court. Maybe you've heard of "interim costs and disbursements in family law" but aren't sure what it really means, or how it could help you. Good news: you're not alone, and help is at hand.

Interim costs and disbursements are powerful legal tools that can level the playing field when one party has access to resources and the other is feeling cornered. But who actually qualifies, how does it work, and what do judges look at when making these decisions? This comprehensive guide answers those questions and more—so you can move forward with confidence.

What Are Interim Costs and Disbursements in Family Law?

Interim costs and disbursements in family law are court-ordered payments made by one party to help the other pay legal expenses while the family law case is still ongoing—not just at the end of the trial. Think of it as a legal "advance" to ensure both sides have a fair shot, especially when there's a financial imbalance.

Key Points

  • Interim costs: Funds to cover legal fees during proceedings
  • Interim disbursements: Funds to cover out-of-pocket expenses like expert reports, court filing fees, or valuations
  • Purpose: To promote fairness and access to justice, preventing one party from being forced to settle or abandon their case due to lack of funds

Why Do Interim Costs and Disbursements Matter in Family Law?

In family law, power imbalances are common. One spouse may control most of the assets or income, while the other struggles to pay for a lawyer, expert witnesses, or even basic court fees. Without help, the less-resourced party might get steamrolled—hardly the "just and equitable" process Ontario's courts strive for.

Interim costs and disbursements in family law:

  • Prevent injustice caused by financial disparity
  • Enable both parties to participate fully in the legal process
  • Support access to justice, a fundamental principle in Canadian law

When Can You Apply for Interim Costs and Disbursements in Family Law?

You can apply for interim costs and disbursements at any stage before the final trial judgment, usually when:

  • There's a clear financial imbalance between spouses
  • You can't fund your own legal representation or necessary disbursements
  • Your case raises complex legal or factual issues that require expert input
  • Denial of funding would undermine your ability to present your case

Common Triggers

How Courts Decide on Interim Costs and Disbursements in Family Law

Judges don't hand out interim costs and disbursements like candy. Instead, they follow a careful, principled approach. Ontario courts look at several factors, and the threshold is high—you need to show genuine financial need and a real risk of injustice.

Leading Ontario Cases

1. The Okanagan Test

British Columbia (Minister of Forests) v. Okanagan Indian Band, 2003 SCC 71 [CanLII]

This Supreme Court of Canada case set out the key criteria for interim costs, later adopted in family law. In plain English, the court asks:

  • 1
    Is the case important or special?

    The case must raise novel legal issues, have public importance, or involve special circumstances (most family law cases meet this test due to their impact on children and families)

  • 2
    Does the applicant lack resources?

    You must prove you genuinely cannot afford to fund the litigation yourself

  • 3
    Can the other party pay?

    The opposing spouse must have the financial means to contribute

  • 4
    Would denial prevent justice?

    Without interim costs, would the case collapse or would you be forced into an unfair settlement?

2. Ontario Family Law Application: MacDonald v. MacDonald

MacDonald v. MacDonald, 2015 ONSC 2017 [CanLII]

In this case, the court clarified the Okanagan test's application in family law, focusing on the fairness and access to justice for both parties. The judge emphasized that interim costs are not about punishing the wealthier spouse—they're about ensuring both parties can meaningfully participate in resolving disputes that affect their children, property division, and spousal support.

Judicial Considerations

Judges will ask:

  • Can the applicant afford to pay their lawyer and necessary experts?
  • Is the other party financially capable of contributing?
  • Would denying the request hinder a fair trial?
  • Is the funding for legitimate, necessary legal steps—not fishing expeditions?

Courts are cautious: Interim costs and disbursements are the exception, not the rule. The applicant must exhaust other funding avenues (such as loans or, in rare cases, legal aid) before seeking an order.

What Kinds of Expenses Can Be Covered?

Not all expenses qualify. Generally, interim costs and disbursements in family law can cover:

Covered Expenses

  • Legal fees for your lawyer's ongoing work
  • Fees for expert reports (e.g., business valuators, parenting assessments)
  • Court filing and process server fees
  • Reasonable travel or accommodation costs for required court appearances

Not Covered

  • Everyday living expenses
  • Retrospective costs (expenses already paid)
  • Frivolous or unnecessary expenditures

Step-by-Step: How to Apply for Interim Costs and Disbursements in Family Law

Trying to get interim costs and disbursements isn't a walk in the park—there's a process to follow, and you must come prepared.

1

Gather Your Evidence

  • Financial statements: Show your assets, liabilities, income, and expenses
  • Affidavit: Swear to your inability to pay, and explain how lack of funding would prejudice your case
  • Budget: Detail anticipated legal costs, disbursements, and the need for expert reports
2

Prepare Your Motion

You'll need to serve and file a motion (formal court request) for interim costs and disbursements. Include:

  • • Legal basis (case law, statutes)
  • • Specific amounts requested
  • • Explanation of necessity
3

Serve the Other Party

Give the other side notice. They'll have a chance to respond, often contesting your need or the size of the request.

4

Attend the Hearing

Both parties (and their lawyers) appear before a judge, who'll hear arguments and review the evidence.

5

Await the Decision

If successful, the court will specify who pays what, when, and for which purposes.

Pro tip: Work with a family law lawyer experienced in these motions. The process is technical, the stakes are high, and mistakes can be costly.

Common Scenarios: When Are Interim Costs and Disbursements Most Needed?

Stay-at-home parent versus high-income earner

One spouse controlled the finances during the marriage and now withholds access, leaving the other in the lurch.

Complex property division

Business interests, overseas assets, or disputes over hidden property require costly valuations or forensic accounting.

High-conflict parenting disputes

Parenting capacity assessments, voice of the child reports, or supervised access reviews may be crucial—and expensive.

Family violence or power imbalance

A vulnerable party needs resources to ensure safety and fair representation.

Tips for Maximizing Your Chances

Strategic Preparation Checklist

  • Be transparentDisclose your finances fully—don't leave gaps that raise suspicion
  • Detail necessitySpecify exactly what the funds are for, and why they can't wait until the end of the case
  • Show attempts to self-fundCourts look kindly on those who've tried to borrow, cut costs, or otherwise solve the problem themselves
  • Keep requests reasonableAsking for the moon rarely works; focus on immediate, essential costs

Risks and Realities: What to Expect

Interim costs and disbursements in family law aren't guaranteed. Even with a compelling case, courts may:

  • Grant only part of your request
  • Set strict reporting requirements
  • Require repayment if you ultimately lose the case or the funds weren't used as promised

Remember: A poorly prepared motion can harm your credibility and set back your case. Professional legal guidance is crucial.

Frequently Asked Questions

Do I have to repay interim costs if I lose my case?

Possibly. Courts may order repayment if you're unsuccessful, especially if the funds weren't used appropriately. However, each case is unique—repayment isn't automatic.

How long does it take to get an interim costs order?

It varies. In urgent cases, orders may be granted within weeks; in complex disputes, several months. Your lawyer can expedite the process where possible.

Can I get interim costs for living expenses?

No. Interim costs are for legal fees and litigation-related disbursements only. For living expenses, you'd seek spousal or child support.

What if my spouse refuses to pay the court-ordered interim costs?

The court has enforcement tools—garnishment, contempt proceedings, or liens on property. Non-compliance can seriously damage your spouse's credibility with the judge.

Do interim costs cover expert reports?

Yes, if they're necessary. Business valuations, parenting assessments, forensic accounting—these can all qualify as legitimate disbursements.

Can I apply for interim costs more than once?

Yes, if circumstances change. For example, if the case becomes more complex or your financial situation worsens, you can bring a fresh motion.

Will interim costs cover my lawyer's entire bill?

Not necessarily. Courts typically grant partial funding—enough to ensure fairness, not a blank check. You may still need to contribute or find other funding sources.

Is legal aid available for family law cases in Ontario?

Legal Aid Ontario provides limited family law services, but eligibility is strict and funding is often insufficient for complex cases. Interim costs can fill the gap.
