“I want to thank you. I hired you because you emphasized mediation, and I kept on hiring you in the face of one of my brothers and one of my friends insisting I hire a "bulldog" to counter (my ex’s) "bulldog." I'm glad I ignored their advice.”

How to Calculate Child Support in Alberta

Alberta child support is calculated using the Federal Child Support Guidelines and gross parental income. If children live with only one of their parents, only the income of the paying parent is taken into consideration. If the children live with each parent approximately the same amount of time, child support is calculated for each parent separately and the amounts are set-off against each other. The result is that only the higher earning spouse pays child support.

Child support claims can be very complex. Many issues can arise, including the calculation of income, eligibility of section 7 expenses (special expenses) and hardship claims. This website offers basic legal information only. For legal advice and representation in any child-support related matters, we recommend you consult an Alberta family lawyer. A family lawyer can bring or defend a child support claim on your behalf, and make submissions to the court. Contact us for more information on what a family lawyer can do for you.
