Child Support for Adult Children

What happens to a payor’s child support obligations once his or her children are adults pursuing higher education? Does child support terminate, or does it remain payable? An Ontario court grappled with this interesting question in Makdissi v. Masson.

The Parties’ Story

The parties were married in June 1993, separated in September 2001, and divorced in March 2004. They had two children together, aged 22 and 23.

The father was a university professor and the mother was a physician.

In 2011, an order for child support was made. The judge at the time decided that the child support tables were not appropriate in determining the level of child support, and ordered the mother to pay the father child support in the amount of $4,000 per month, as well as 82% of the children’s extraordinary expenses. This amount was meant to cover the “indirect expenses” for the children, such as housing, utilities and groceries.

Since 2011, one child had been admitted to a doctoral program at a university, and the other child also hoped to pursue a doctoral program at another university.

The mother brought a motion for an order terminating support for each child on the date they completed, or would complete, a second post-secondary degree (i.e., when they each had earned a master’s degree).

The Relevant Legal Principles

Section 17(4) of the Divorce Act provides that the court must be satisfied that there has been a “change of circumstances” before granting a variation in child support.

In addition, section 14 of the Federal Child Support Guidelines provides that where the amount of support was calculated using a basis other than the child support tables (as was the case here), any change in the “condition, means, needs or other circumstances of either spouse or of any child who is entitled to support” constitutes a change in circumstances.

The Divorce Act also outlines that a parent may be obligated to continue paying child support for a child that “is the age of majority or over and under their charge but unable, by reason of illness, disability or other cause, to withdraw from their charge or to obtain the necessities of life.”

The factors often applied to this question are from a Supreme Court of British Columbia case, Farden v. Farden, and include:

  • whether the child is in fact enrolled in a course of studies and whether it is a full-time or part-time course of studies;
  • whether or not the child has applied for, or is eligible for, student loans or other financial assistance;
  • the career plans of the child, i.e., whether the child has some reasonable and appropriate plan or is simply going to college because there is nothing better to do;
  • the ability of the child to contribute to his own support through part-time employment;
  • the age of the child;
  • the child’s past academic performance, whether the child is demonstrating success in the chosen course of studies;
  • what plans the parents made for the education of their children particularly where those plans were made during cohabitation; and
  • at least in the case of a mature child who has reached the age of majority, whether or not the child has unilaterally terminated their relationship from the parent from whom support is sought.

The Court’s Decision

The court found, firstly, that there had been a significant change in circumstances that justified a review of child support in this case. One child was on their way to completing a master’s degree, and the other child was enrolled in a PhD program. Furthermore, the incomes of the parties and the children had changed.

In concluding that the change in circumstances did not end the mother’s obligation to pay child support, the court noted that this was a family with high academic expectations, very intelligent and academically motivated children, and a combined income approaching one million dollars per year. In the court’s view, the parties could afford post-secondary education for their children, and the children had not repudiated their relationship with the mother. Overall, the court found that, in this instance, all of the Farden factors favoured an ongoing entitlement to support.

Frequently Asked Questions - child support

In cases involving child support, you must typically serve and file financial disclosure. Financial disclosure is providing facts about your finances to the opposing party and the court, including your income, spending, assets such as property and other valuables, as well as debts.

Yes, it may be possible for you to pay for child support directly to your child, but it’s worth noting that this only happens in rare cases. Usually, you’re obligated to pay it to the other parent.

The province asserts the rights of the child through child support. As such, neither parent has the legal ability to bargain away or waive child support.

Parenting arrangements affect child support. Under Section 9 of the Federal Child Support Guidelines:

Where a spouse exercises a right of access to, or has physical custody of, a child for not less than 40 percent of the time over the course of a year, the amount of the child support order must be determined by taking into account:

  1. the amounts set out in the applicable tables for each of the spouses;
  2. the increased costs of shared custody arrangements; and
  3. the conditions, means, needs and other circumstances of each spouse and of any child for whom support is sought.

The Ontario courts have broad discretion to determine the merits and context of a child’s post-secondary education and when child support payments should cease.

No. Child support is memorialized in the divorce settlement agreement. It is not affected by the marital status of the parents.

Child support depends on the annual gross income of the parents.

Child support is calculated by considering the following:

  • The number of children that require support
  • The paying parent’s residential province
  • The paying parent’s annual income before tax
