How the amount is set for an adult child
Under section 3(2) of the Federal Child Support Guidelines, a court can use the regular table amount plus special expenses, or, if that is not suitable, set an amount that fits the child's needs and means and each parent's ability to pay. Courts often look at whether the child lives at home, works part-time, has savings or student loans, and what the program costs.
Tuition and school costs
Post-secondary costs are a section 7 special expense, usually shared by the parents in proportion to income, after the child's own reasonable contribution. Split the cost.
Quebec
In Quebec, support for an adult child in school is also possible. The child or a parent can ask for it, and the court looks at the child's needs and resources.
