This booklet explains how child support is calculated and enforced.
Proof of Income
If you pay child support or if your income is required to calculate a child support amount, you must provide proof of your income to the other parent.  Under the Child Support Guidelines, that must include copies of the following documents:
  • Income Tax Returns for each of the past three years;
  • Notices of Assessment and Reassessment for each of those years
  • Your most recent statement of earnings or confirmation of income from your employer if you are an employee;
  • If you are self-employed or control a corporation, the businesses’ financial statement and a statement showing all wages and other similar payments;If you receive employment insurance, social assistance, a pension, worker’s compensation or disability payment, documentation of that income; and,
  • Information relating to the income of a trust where you are a beneficiary under a trust.
If you are involved in a family court case, you should review rule 13(6) and 13(7) of the Family Law Rules to make sure that you have provided the other party with the necessary disclosure of your income.  You should also review the family court forms for each step in the proceeding to make sure that you have filed the necessary documents with the court.
Filing Your Separation Agreement to Enforce Child Support Payments
If you have a separation agreement and would like the Family Responsibility Office to enforce the child support payments, you can file it with the court and then register it with the FRO for enforcement. To file your separation agreement, you will need to complete an Affidavit for Filing Domestic Contract or Paternity Agreement (Form 26B) with the court.
Updated Income Information
Once child support is in place, any person whose income was required to calculate child support must provide updated documentation of their income to the other party each year within 30 days of the anniversary of the court order or separation agreement that sets out the support payment, unless the parties have agreed not to do so in writing. This is done by sending a copy of the most recent Income Tax Return and Notice of Assessment to the other party.

In addition, either party can always request income disclosure from the other once a year, as long as his or her income was required to calculate the amount of child support. Once a request for income disclosure is made, all of the documents listed in the section titled "Proof of Income" must be provided, including Income Tax Returns and Notices of Assessment for the past three years. Read answers to common questions about these new rules.

Basic Forms
