Unpaid Child Support and Small Claims Court
Child support is a family law matter, and formal support orders are enforced through family court and the state child support enforcement program. Small claims court is not the place to enforce a support order. There are, however, situations involving money owed for a child's care that small claims court can address, depending on your state.
Situations that may belong in small claims court:
- An informal agreement between parents to pay a set amount of support that was never made a court order
- A promise to pay specific expenses, such as daycare, tuition, medical bills, or activities, that was not kept
- Reimbursement of a child's expenses one parent paid in full after the other agreed to split them
- Support arrears already reduced to a money judgment, in the states that allow collection of such judgments in small claims
- Money a parent borrowed from the other for the child's needs
Situations that belong in family court or the support agency:
- Missed payments under an existing child support order
- Modifying the amount of support
- Establishing paternity or an initial support order
Can You Sue in Small Claims Court?
Only for the contract-type claims listed above, and only in jurisdictions whose rules permit it. Claims must be within the state limit (typically $2,500 to $25,000).
Legal claims that apply:
- Breach of contract — an agreement to pay support or expenses that was not honored
- Unjust enrichment — one parent paid the other's share of the child's costs
- Enforcement of a prior judgment — where state rules allow
What You Need to Prove
- The agreement — texts, emails, a written note, or witnesses to the promise
- The expenses or amounts — receipts, invoices, tuition statements
- What was paid and what was not — a ledger
- Demand — your written request for payment
Evidence to Gather
- Written agreement or messages showing the promise to pay
- Receipts for daycare, medical, school, and activity expenses
- Payment history showing past contributions and the gap
- A ledger of what is owed
- Any existing court order or judgment, if the claim involves one
- Your demand letter
Step-by-Step: Filing Your Claim
Step 1: Confirm the Right Forum
Call the court clerk or the state child support agency. If a support order exists, use the agency's enforcement first.
Step 2: Document the Agreement and Expenses
Gather the messages, receipts, and ledger.
Step 3: Send a Demand Letter
State the agreement, the amount owed, and a deadline.
Step 4: File and Serve
File in the county where the other parent lives. Name them individually.
Step 5: Present the Case
Show the agreement, the receipts, and the ledger. Keep the focus on the money owed under the agreement, not the broader custody situation.
What You Can Recover
- Unpaid amounts under the informal agreement
- Reimbursement of the other parent's share of documented expenses
- Filing and service costs
Final Thoughts
Court-ordered support belongs with the family court and the support agency, which have powerful free enforcement tools. For promises and expenses outside an order, small claims court can turn the agreement into a judgment in the states that allow it.
