Letters: Child Support Battles & Co-Parenting Overspending: What Are My Rights?
2026-10-05
Reader Question
“Dear Robinson, I'm at my wit's end. My ex-husband, Mark, and I divorced three years ago, and we have two amazing kids, Emily (10) and Josh (7). The court ordered him to pay a set amount of child support every month, which he does, thankfully. But it feels like every other week, I get an email or text demanding more money for 'extras.' He insists Emily *needs* to be in competitive gymnastics, which costs a fortune in fees, travel, and uniforms. And Josh, apparently, can't live without the latest designer sneakers and private coding lessons. He sends me invoices for these things and expects me to just pay half, on top of the child support! He says it's 'for the kids' and I'm being selfish if I don't contribute. I work full-time, but I'm also trying to save for my own retirement and the kids' college. My new partner, David, is supportive, but this constant financial pressure is putting a strain on our relationship too. Mark earns significantly more than I do, but he acts like I'm made of money. I've tried to talk to him, but he just gets angry and says I'm depriving our children. What are my legal obligations here? Am I really required to pay for every single 'extra' he decides the kids need? How do I set boundaries without looking like the bad guy or hurting my children? I feel trapped and financially exhausted. Please help! Sincerely, Struggling Mom”

Expert Advice from Robinson Roacho
Dear Struggling Mom,
Your letter highlights a common and incredibly stressful challenge many co-parents face. It’s natural to feel overwhelmed when financial demands extend beyond a court order, especially when coupled with emotional pressure. Let's break down your situation with a clear, empathetic approach.
First, understand the purpose of child support. Child support is a legal obligation for one parent to provide financial assistance for the everyday needs of their children. This typically covers basic necessities like food, shelter, clothing, and general education expenses. The amount is usually determined by state guidelines, considering both parents' incomes and the children's needs.
When it comes to 'extras' like competitive sports, private lessons, or designer items, these fall into a different category. Unless specifically outlined in your divorce decree or a separate co-parenting agreement, you are generally not legally obligated to split the cost of every discretionary expense your ex-husband decides on. Many divorce agreements include clauses for shared 'extraordinary expenses,' which are often defined as significant, unforeseen costs like major medical bills not covered by insurance, or agreed-upon educational needs. However, a parent unilaterally deciding on expensive activities or luxury items for the children usually doesn't create a legal obligation for the other parent to contribute without prior agreement.
Here's how to approach this:
1. Review Your Divorce Decree: This is your primary legal document. Carefully read through it with a fine-tooth comb. Does it specify how 'extraordinary expenses' are handled? Does it list specific activities or educational costs that both parents agreed to share? If it's vague or silent on these specific types of expenses, then you have more leeway.
2. Communicate Clearly and Firmly: While it's difficult, you need to establish boundaries. You can say something like, 'Mark, I understand you want the best for Emily and Josh, and I do too. However, our divorce decree outlines my financial obligations, and these additional expenses are not part of that agreement. I'm happy to discuss mutually agreed-upon expenses that fit within my budget, but I cannot commit to every activity you choose without prior discussion and agreement.' Focus on 'we' and 'agreement' rather than 'you' and 'demand.'
3. Propose a Co-Parenting Budget for Extras: If you are willing and able to contribute to *some* extras, propose creating a separate, mutually agreed-upon budget for discretionary activities. This allows both parents to have a say and ensures that expenses are affordable for both. You could suggest a 50/50 split on *agreed-upon* activities, or a pro-rata split based on your respective incomes, but only for items you both greenlight.
4. Consider Mediation: If direct communication proves ineffective, a neutral third-party mediator can be incredibly helpful. A mediator can facilitate discussions, help you both understand your legal document, and guide you toward a revised co-parenting financial agreement that works for everyone, especially the children. This is often less adversarial and costly than going back to court.
5. Legal Counsel: If your ex-husband continues to harass you or threatens legal action over these expenses, it's time to consult with a family law attorney in your state. They can clarify your specific legal obligations based on your divorce decree and state laws, and advise you on how to respond to his demands or pursue formal modifications if necessary. Please note that legal and tax regulations, including child support guidelines, can change annually. An attorney can provide the most current 2026 information relevant to your jurisdiction.
6. Focus on Your Financial Stability: Protect your own financial well-being. Continue saving for your retirement and the children's college education. Remember, a financially stable parent is better equipped to support their children in the long run. Don't let guilt or emotional manipulation jeopardize your future.
The goal here isn't to deprive your children but to ensure financial fairness and sustainability for both households. By understanding your legal standing and setting clear boundaries, you can regain control and reduce the stress this situation is causing.
