When Your Co-Parent Won't Pay Their Share
You paid the dentist. You sent the receipt. Nothing happened. You sent it again. Still nothing.
This is the most common ongoing dispute in co-parenting, and how it ends usually depends on decisions you make in the first month.
First, separate the two things
Unpaid child support and unreimbursed shared expenses are different problems with different remedies.
Child support is typically enforceable through your state's child support enforcement agency, which has tools no individual has — wage withholding, tax refund interception, licence suspension. It is generally free to use. If support is the issue, that agency is usually the first call, not a lawyer and not a text.
Unreimbursed expenses are usually a contempt or enforcement matter through the court that issued the order. Slower, and it depends heavily on what you can show.
Work out which one you are dealing with, because the paths do not overlap.
Before anything else: check your own compliance
Not a comfortable question, but the first one that gets asked.
Did you follow the order? If it required consultation above a threshold, did you consult? If it set a submission deadline, did you submit inside it? Did you provide a receipt?
An enforcement request from a parent who followed the process is straightforward. One from a parent who booked a $900 activity without asking and submitted it four months later becomes an argument about both parties, and often stops being about the money at all.
What to do, in order
Send a clear written request. The expense, the date, the amount, the category, the receipt attached, and the specific amount owed under the split in the order. Not "you still owe me for the dentist."
Give a deadline. Fourteen days is reasonable. Say the date.
Send one reminder. One. Repeated demands become their own problem and start looking like harassment, which shifts the story away from the debt.
Keep everything in one channel. Requests scattered across text, email and phone calls are hard to present and easy to dispute. One channel with timestamps is worth a great deal.
Then escalate properly. For support, the enforcement agency. For expenses, an attorney about a motion to enforce. Both work better with a clean record and worse with a shoebox.
What not to do
Do not withhold parenting time. This is the most common instinct and the most damaging response available. In essentially every state, support and parenting time are separate obligations — the other parent's failure to pay does not suspend their right to see the children, and withholding time can put you in violation of the order regardless of what they did. It converts your strong position into a mutual problem.
Do not stop paying your own share for the same reason.
Do not tell the children. It is a heavy thing to hand a child, it does not produce payment, and courts notice.
Do not let it accumulate silently. Two years of unclaimed expenses is much harder to enforce than three months of documented ones, and some orders impose deadlines that bar stale claims entirely.
What actually helps at a hearing
Judges see a lot of these. What distinguishes them is the record.
A parent who arrives with a dated list — each expense, its category, the receipt, the date the request was sent, whether it was approved, disputed or ignored — is in a different position from one who arrives with a story. Not because the story is untrue, but because one is checkable within a few minutes and the other is not.
Whether any particular record is admitted, and what weight it carries, is the court's decision. But contemporaneous beats reconstructed, consistently.
Where Civly fits
This is the situation Civly's expense flow is built for, and the honest description of what it does is narrow.
Each expense is logged when it happens with a receipt attached, split at the percentage your order sets, and sent as a request. The other parent approves, disputes or pays — and if they do nothing, that is recorded too, with a date. Nothing gets reconstructed from memory eleven months later, and there is no argument about whether a request was sent.
It does not make anyone pay. Nothing does except the enforcement mechanisms above. What it means is that when you use one of them, you have the thing they run on.
This is general information, not legal advice. Enforcement options for support and for unreimbursed expenses differ by state and depend on your own order. Talk to a family law attorney licensed where you live, or contact your state's child support enforcement agency.
