Child Support Recalculation Program

Register Now! The Alberta Child Support Recalculation Program increases access to justice by providing many parents with a way to change their child support orders with ease, transparency and decreased cost.

The Recalculation Program (RP) is an administrative service that annually recalculates court-ordered child support based on current income tax information. Our goal is to help parents keep child support levels in line with income so families can avoid the time and expense of asking the courts to review their child support orders.

Parents must already have a valid court order (or binding agreement) for child support before they can be registered with RP. Not all court orders are eligible for registration with RP. If the child support order is eligible, RP can recalculate both table (monthly) amounts of child support and proportionate shares of special or extraordinary expenses.

RP's General Information Sheet provides a summary of their service.

New legislation changes

Following public consultations completed in early 2014, changes to RP's legislation have been made. The changes increase access to justice by making it easier for parents to access recalculation services and by increasing clarity for the parties and courts. The key changes made are:

  • Mandatory standard recalculation clauses: Commencing March 1, 2015, all child support orders granted in Alberta must specifically indicate whether RP may recalculate the support amounts. This includes orders granted both under provincial legislation (e.g. Family Law Act) and the federal Divorce Act. The standard clauses to be used can be found at Recalculation clauses in court orders.
  • Minimum deemed guideline income: A party who does not provide income information to RP will be deemed to earn a minimum of $23,296 (i.e. what they would earn working 40 hours a week for minimum wage).
  • Objections to recalculation decisions: Parents who object to a recalculated amount must state in their court documents that they do not agree with the recalculated amount and attach a copy of RP's written decision.
