I belong to many online single parenting and co-parenting groups, and one question comes up again and again: Who is responsible for sharing the financial costs of raising children after separation or divorce?

Whether it’s child support, medical expenses, or reimbursements for extracurricular activities, the truth is simple—it takes two parents to raise a child, and both must share the costs.

Child Support vs. Shared Parenting Costs

When parents separate, one thing doesn’t change: both parents remain financially responsible for their children.

Co-parenting is more than just dividing parenting time; it’s about sharing the financial responsibilities that come with raising kids.

Too often, child support is viewed as the only obligation, but that’s not the case. Yes, it helps cover the basics such as food, clothing and housing.  Kids also need support beyond the day-to-day essentials.

Why Both Matter

  • Child Support → Provides stability with essentials like housing, food, clothing, and healthcare
  • Extracurricular Costs → Help children grow, thrive, and explore passions. Sports, arts, music, and academic programs aren’t “extras”—they’re investments in a child’s future

When one parent refuses to contribute to these costs, it’s not the other parent who suffers—it’s the child. Missed opportunities, limited experiences, and feelings of exclusion can have lasting effects.

The Problem with Excuses

It’s true: kids can’t do every activity because of costs. But too often, the excuse of “I can’t afford it” is used while money is spent on luxury items, salon trips, European vacations, or non-essential services.

The truth is that many extracurricular activities directly support a child’s development teaching discipline, teamwork, confidence, and creativity.

If finances are tight, honesty goes a long way. But telling a child “It’s too expensive” when the reality is different only sends mixed messages.

The Legal Side of Co-Parenting Finances

If there’s a court order or parenting plan that requires parents to split costs or reimburse within a set timeframe, it is legally binding—just like child support.

  • Reimbursements aren’t optional
  • Ignoring agreed-upon financial responsibilities is not just unfair, it’s a violation of a legal agreement

These financial commitments ensure that both parents carry their share of the responsibility instead of leaving the burden on one parent.

The Bottom Line

Co-parenting means teamwork. It means showing up financially as well as emotionally, even when you don’t live under the same roof.

By fulfilling both child support obligations and extracurricular contributions, children gain the stability and opportunities they need to succeed in every area of life.

When a parent refuses to meet their financial responsibilities, they aren’t punishing their ex.  They are limiting their own children.

If you truly want what’s best for your kids, that means being there financially, emotionally, and consistently.
