When a former partner stops paying child support, the financial impact can quickly become difficult for the parent caring for the child. Missed payments can affect everyday expenses such as housing, food, childcare, education and other costs associated with raising a child.

In Ontario, unpaid child support should not simply be treated as a private disagreement between former partners. If you have a court order or written support agreement, there are legal and administrative options available to address missed payments. The Family Responsibility Office (FRO) can collect and enforce eligible support payments, while a family lawyer in Ontario can help when the situation requires legal advice or court action.

What Should You Do If Your Ex-Partner Stops Paying Child Support?

Your first step should be to determine whether the missed payment is a temporary delay or part of a continuing pattern.

If your support case is registered with the Family Responsibility Office, you should keep track of missed payments and review your FRO account. Ontario advises support recipients to contact FRO if a payment has not been received for more than 30 days.

You should also keep copies of:

  • Your child support order or written agreement
  • Records of payments received
  • Bank statements showing missed payments
  • Correspondence with your former partner about support
  • Information about unpaid special or extraordinary expenses
  • FRO statements and notices
  • Any information you have about changes to the payor's employment or income

Keeping accurate records can make it easier to determine the amount of child support arrears and understand what steps may be available.

How Does the Family Responsibility Office Help With Unpaid Child Support?

The Family Responsibility Office (FRO) is an Ontario government program that helps collect, distribute and enforce child and spousal support payments. When a support order is filed with FRO, it can take enforcement action when payments are not made as required.

Depending on the circumstances, enforcement measures can include:


FRO's role is important, but it does not change the amount of support ordered or resolve every family-law dispute. A court may be required when the underlying support order needs to be changed or another legal issue needs to be addressed.

When Should You Contact a Family Lawyer in Ontario?

You may want to speak with a family lawyer in Ontario when the issue goes beyond a straightforward missed payment.

Legal advice may be particularly useful if:

Your Ex-Partner Claims They Cannot Afford Child Support

A former partner may say they have lost their job, experienced a significant reduction in income or are otherwise unable to continue paying the existing amount.

A change in financial circumstances does not automatically cancel an existing support obligation. If the amount needs to change, the appropriate legal process should be followed. Ontario's FRO specifically notes that it cannot change the amount of support in an existing order; a judge may need to make that change.

A family lawyer Ontario can help assess whether a variation of child support may be appropriate and what financial information may be required.

Child Support Arrears Are Continuing to Increase

If several payments have been missed, the amount owing can become significant. Rather than waiting for the arrears to grow further, it may be useful to obtain legal advice about enforcement options and the appropriate process for addressing the outstanding amount.

FRO also provides a Statement of Arrears process for reporting unpaid support, certain expenses and related amounts that are owed.

Your Support Order or Agreement Is Unclear

Disputes can arise when parents disagree about:

  • The monthly child support amount
  • When support should end
  • Shared or special expenses
  • Income information
  • Changes in the child's circumstances
  • Whether a payment was actually made

A family lawyer can review the wording of the order or agreement and explain what it requires before you take further action.

Your Former Partner Is Avoiding Enforcement

If the other parent has changed jobs, moved, become difficult to locate or appears to be deliberately avoiding their support obligations, the situation may require more than simply requesting payment.

Ontario's enforcement system has specific processes for dealing with support payors who cannot be located or who repeatedly fail to meet their obligations.

Can You Stop Child Support Payments Because Your Ex-Partner Denies Parenting Time?

No. Child support and parenting time are separate legal issues.

A disagreement about parenting time does not automatically remove a parent's child support obligation. Likewise, failure to receive child support does not automatically mean parenting time should be denied.

If you are dealing with both unpaid support and a parenting dispute, it is important to address the issues separately and obtain appropriate family law advice in Ontario rather than trying to resolve one issue by withholding the other.

What Information Should You Take to a Family Lawyer?

Before meeting with a family lawyer in Ontario, organize the information that relates directly to the support problem.

Bring:

  • The current child support order or agreement
  • A payment history
  • FRO correspondence, if applicable
  • Bank records showing missed payments
  • Recent communication with your former partner
  • Information about known changes in the payor's employment or income
  • Records of eligible shared or special expenses
  • Any previous court documents relating to support

A clear timeline of when payments stopped and how much remains unpaid can also help your lawyer understand the situation quickly.

When Legal Advice Can Make a Difference

Not every missed payment requires an immediate court application. If your case is already registered with FRO, the first step may simply be to contact FRO and ensure your payment information is accurate.

However, legal advice can become particularly important when there are child support arrears, disputes over income, requests to change support, unclear agreements, enforcement difficulties or other family-law issues happening at the same time.

A family lawyer in Ontario can help you understand your rights, assess the available options and determine whether further legal action is appropriate for your circumstances.

Get Legal Guidance About Child Support in Ontario

If your former partner has stopped paying child support, do not assume that you have to manage the situation alone. Ontario has mechanisms for enforcing support obligations, but the right next step depends on your existing order or agreement, payment history and individual circumstances.

If you are dealing with unpaid child support, growing arrears or a dispute about the amount of support, speaking with a qualified family lawyer in Ontario can help you understand the legal options available to you and your child.
