The most common standard for modification of child support is a substantial change in circumstances. That usually refers to a change in income of the parent who is supposed to be paying support. If the parent who is obliged to pay support suffers a loss of income, that could be a basis for reducing support; conversely, if the parent’s income increases, that could be a basis for increasing support.
Changes in circumstances of the child also can be a reason for modifying support. If the child has significant new expenses, such as orthodonture, special classes, or health needs that are not covered by insurance, that too can be a reason for increasing support.
Significant changes in the income of the parent seeking support also can be a basis for modification. If the custodial parent’s income drops (particularly through no fault of the custodial parent), that might be a basis for increasing support. If the custodial parent’s income increases, that might be a basis for reducing support from the noncustodial parent.
