If you are paying or receiving child support, there may come a time when you feel the terms of your support order or domestic contract should be changed. For example,

• your income may change
• your former spouse may remarry, or
• your child graduates from school and gets a job.

The Family Responsibility Office cannot change any of the terms in your support order or domestic contract.

Only the courts can change your order.

How to change a domestic contract

The support payor and the support recipient have to negotiate a new domestic contract with new support terms. The new contract will have to be filed with the Ontario Court of Justice or Superior Court of Justice (Family Court) and then sent to us.

How to change a support order

You must ask the court to change a support order by filing a Motion to Change form, which you can find online at www.ontariocourtforms.on.ca. For more information about this see the Ministry of the Attorney General’s Self Help Guide for Motions to Change.

Once the support order is changed, you must send a copy of it to us at:

Family Responsibility Office
Ministry of Community and Social Services
P.O. Box 220
Toronto ON M3M 3A3

Note: The process for changing a support order is different if either the payor or recipient lives outside Ontario. Learn More

When a support order has been assigned to a social services delivery agency

If a support order has been assigned to a social services delivery agency, such as Ontario Works or the Ontario Disability Support Program, the agency must be involved in all court proceedings or agreements to change the support order. Please provide your caseworker at the agency with a copy of any motion to change the support order.

To find out if your support order is assigned

Fill out a Confirmation of Assignment form and send it to the address or fax number indicated on the form.

If your support order is assigned, you will be given instructions on where to send your court documents.
