Deviating from the Child Support Guideline
The factors that might convince the court to deviate from the guideline are:
The child's financial resources (does the child have income or assets of their own?)
The custodial parent's financial resources
The standard of living the child would have if the parents were together
The child's physical and emotional health
The child's educational needs
The non-custodial (paying) parent's financial resources
Inflation
Either parent's needs for education or job training
Travel costs for visits between the child and a parent
Anything else the court finds important
A full description of these factors is here. If any of these factors seems higher than usual in your case, you can ask the judge for an amount of child support that is higher or lower than the guideline.

Tip:
Is there something about your family situation that is unusually expensive? This might include travel costs, medical bills or something else related to the children. If so, ask the judge or magistrate to raise or lower the child support calculated by the guideline!
Common reasons for deviation are:
A parent lives far away
A parent is in school
A child has a learning disability
A child has an expensive illness
