How does child support work with shared parenting? Do we still share special and extraordinary expenses?

Parents sharing custody of a child

Child support in shared parenting situations gets a little tricky.  A lot depends on the specifics, so it would be a good idea to speak to a good family lawyer.  However, this page goes over some of the general principles.


When you have a "shared parenting regime", meaning that a child spends at least 40% of his or her time with each parent, then child support changes for that child.  The idea is that each parent should be paying his or her proportionate share of all of the costs for raising the child based on that parent's income.  Figuring out exactly what a child costs can be a exhausting exercise, so the Supreme Court said, in the Contino case that parents should start by setting of the table child support payments under the Child Support Guidelines for the shared child.  For example, if one parent makes $100,0000 and one parent makes $50,000.00, the parent who makes $100,000 will pay the table amount of child support for $100,000 income minus the table amount of child support for $50,000 income.  It is NOT correct for the parent making $100,000 to pay support based on a $50,000 income.


However, the presumption is that with the set off, after support is paid, each parent will be bearing an appropriate amount of the cost of raising the child.  If that is not the case, and one parent continues to disproportionately pay for the child's expenses (for example, only one parent buys clothes, birthday gifts, toys etc.), then it is not appropriate to just do the "set off" and it would be more appropriate to figure out the child's expenses and divide them up in proportion to the parent's incomes.  Ideally, that would be done by coming up with an average monthly amount for one parent to pay to the other.


The Contino case sets out how to deal with child support in shared parenting arrangements.  So, you can read it, or you can listen to this podcast that also explains how that works.   This video also gives an overview of child support. 


You should still be sharing your child's special and extraordinary expenses in proportion to your incomes, no matter how you have worked out "base child support."  It is true that some less expensive sports and other activities are not extraordinary expenses, while others definitely are.  Parents always share the costs of "special expenses" in addition to base child support.  To understand special and extraordinary expenses better, listen to this podcast  and look at this page.

As you can tell, child support in shared parenting arrangements can depend on a lot of specific facts.  Whether an expense is subject to section 7 of the Child Support Guidelines is sometimes difficult for ordinary people to determine, but it is something that good family lawyers and family court judges know immediately.
