How Much Does a Divorce Cost in Ontario?

“How much will this cost me?” is usually the first question people ask when they walk into a family lawyer’s office. It’s a fair question — and one that deserves a straight answer, not a hedge.

The truth is, divorce costs in Ontario vary enormously. A simple, uncontested divorce where both parties agree on everything can cost under $3,000 total. A high-conflict custody battle with property disputes can exceed $100,000 over two or three years. Most divorces fall somewhere in between.

Here’s what actually drives the cost — and where you have some control over it.

Court Filing Fees

Every divorce in Ontario starts with a court filing fee. As of 2026, the fees are:

• $632 to file a joint or sole divorce application at the Superior Court of Justice
• $432 if the application is filed online through the Ontario Court Services portal
• Additional fees apply for motions ($280), conferences ($280), and trial scheduling

These fees are set by O. Reg. 293/92 under the Administration of Justice Act and are non-negotiable. You pay them regardless of whether you hire a lawyer.

Uncontested Divorce: $2,000–$5,000

An uncontested divorce is one where you and your spouse agree on all the major issues — or where there are no contested issues to resolve (e.g., no children, no property disputes). In these cases, the divorce is essentially paperwork.

What’s included:

• Preparing the Application for Divorce (Form 8A)
• Filing the application and supporting documents
• Serving your spouse
• Preparing the Divorce Order and submitting it to the court
• Follow-up until the Divorce Order is issued

Most family lawyers charge $1,500–$4,000 for an uncontested divorce, depending on the complexity. Add the $632 court filing fee and you’re typically under $5,000 all-in.

When this works: Both spouses agree on custody, support, and property — or these issues don’t apply. No court appearances required.

Contested Divorce: $15,000–$50,000+

A contested divorce means one or more issues can’t be resolved by agreement and need to be decided by a judge. The more issues in dispute, the higher the cost.

Common cost drivers:

• Custody and parenting disputes — Often the most expensive issue. Assessments by the Office of the Children’s Lawyer or a private assessor ($5,000–$15,000) are common.
• Spousal support — Disputes about entitlement, amount, or duration under the Spousal Support Advisory Guidelines.
• Property division — Business valuations ($5,000–$15,000), real estate appraisals ($300–$500), pension valuations ($800–$2,500), and forensic accounting.
• Financial disclosure disputes — When one party won’t disclose income, assets, or debts. Motions to compel disclosure cost $3,000–$8,000 each.

Typical cost breakdown for a contested matter:

A two-day trial with full preparation can easily cost $15,000–$25,000 — and that’s just one party’s costs.

Legal Fees: How Family Lawyers Charge

Ontario family lawyers typically charge in one of three ways:

Hourly Rates

Most common for contested matters. Rates range from $250–$600+ per hour depending on the lawyer’s experience and location. GTA lawyers tend to charge more than those outside Toronto.

Everything is billed: phone calls, emails, research, court appearances, travel time, and document preparation. A 15-minute phone call at $400/hour costs $100.

Flat Fees

Common for uncontested divorces and straightforward separation agreements. You know the total cost upfront. This is usually the best option when the scope of work is clear.

Retainer + Hourly

The standard arrangement for contested matters. You pay an upfront retainer (typically $3,000–$10,000), and the lawyer bills against it hourly. When the retainer runs low, you replenish it.

Mediation: $3,000–$7,000

Mediation is often significantly cheaper than litigation and faster too. A mediator (usually a lawyer or retired judge) helps both parties negotiate a resolution.

Typical costs:

• Private mediator: $300–$500/hour, with most mediations taking 4–10 hours
• Total cost: $3,000–$7,000, usually split between both parties
• Each party also needs independent legal advice to review the mediated agreement ($1,000–$2,000)

Mediation works best when both parties are willing to negotiate in good faith. It’s not suitable for situations involving domestic violence, power imbalances, or hidden assets.

Under Rule 2 of the Family Law Rules (O. Reg. 114/99), parties in most Ontario family law cases must attend a Mandatory Information Program (MIP) before their first court date. This free session covers the court process, mediation options, and the impact of separation on children.

Hidden Costs Most People Don’t Expect

Beyond legal fees, divorce carries costs that often catch people off guard:

• Tax implications — Support payments have tax consequences. Spousal support is generally taxable to the recipient and deductible for the payor. Child support is not. Getting this wrong can cost thousands.
• Refinancing the matrimonial home — If one spouse keeps the home, they need to refinance the mortgage in their name alone. Appraisal fees, legal fees, and potentially higher interest rates apply.
• Updated estate planning — You need a new will and powers of attorney after separation. Budget $1,000–$2,500. Not optional — under Ontario law, separation doesn’t automatically revoke a will (unlike divorce, which revokes gifts to a former spouse under the Succession Law Reform Act, R.S.O. 1990, c. S.26, s. 17).
• Parenting assessments — If custody is contested and the Office of the Children’s Lawyer doesn’t get involved, a private assessment costs $5,000–$15,000.
• Moving costs — Someone has to move out. First and last month’s rent, moving expenses, furnishing a new space.

How to Keep Costs Down

You have more control over your divorce costs than you might think:

1. Agree on as much as possible before hiring lawyers. Every issue you resolve between yourselves is an issue your lawyer doesn’t need to litigate.

2. Be organized. Gather your financial documents early — tax returns, pay stubs, bank statements, mortgage documents, pension statements. Disorganized clients cost themselves thousands in lawyer time spent chasing documents.

3. Respond promptly to your lawyer’s requests. Delay is expensive. Every follow-up email, every missed deadline, every rescheduled meeting adds cost.

4. Consider mediation first. If your situation allows it, mediation is almost always cheaper and faster than court.

5. Don’t use your lawyer as a therapist. Legal fees are for legal work. If you need emotional support — and most people do during a divorce — a therapist at $150–$200/hour is much cheaper than a lawyer at $400+/hour.

6. Pick your battles. Fighting over every piece of furniture costs more in legal fees than the furniture is worth. Focus on what actually matters: the children, the house, support, and pensions.

Can I Get the Other Side to Pay My Legal Costs?

Ontario courts can order one party to pay the other’s legal costs, but it’s not automatic. Under Rule 24 of the Family Law Rules, costs are typically awarded to the successful party — but the court considers:

• Reasonableness — Were your costs proportionate to the issues?
• Offers to settle — Did you make a reasonable settlement offer that the other party rejected? Rule 18 offers carry significant costs consequences.
• Conduct — Did either party cause unnecessary delay, fail to disclose, or act in bad faith?

In practice, full indemnity costs are rare. You might recover 50–75% of your costs if you’re successful and the other party was unreasonable. Don’t count on a costs award to cover your legal bills — treat it as a bonus, not a plan.
