Child support is not something two adults can opt out of on their own. The moment a child is born, both parents carry a legal obligation to support that child — and the law treats that obligation as the child’s right to hold, not the parents’ right to negotiate away.
So yes, technically parents can agree to no child support or a reduced amount. But that agreement means nothing without a judge signing off on it. A private deal — even a detailed written contract, even a notarized document — is not a child support order. Without court approval, the obligor is still legally exposed to every missed payment as a permanent judgment debt, and the state IV-D agency can override the arrangement entirely if public benefits are or were involved.
This article explains what it takes to make a no-support agreement actually stick, what courts examine before approving one, how the rules differ across states, and what happens when parents skip the process and rely on an informal understanding.
What Does It Mean to Agree to No Child Support?
When parents say they have “agreed to no child support,” they typically mean one of three things: one parent has told the other they do not want or need payments; both parents have put something in writing confirming the arrangement; or they have included a no-support provision in a broader divorce or separation agreement. None of these, standing alone, produces an enforceable child support arrangement.
“Agreeing” to no child support in the legal sense means something specific and narrower: submitting a written stipulation to a family court, having both parents’ financial circumstances reviewed by a judge, and receiving a signed court order that incorporates the zero or reduced support amount. Anything short of that is an informal understanding, not a legal order.
The distinction matters enormously. Under federal guidelines at 45 C.F.R. §302.56, every state is required to use child support guidelines as a rebuttable presumption in every proceeding. That presumption only gets rebutted when a court makes specific findings about why the agreed amount — including zero — is appropriate. A private agreement between parents does not rebut anything. It simply does not exist in the eyes of the law.
Why Child Support Belongs to the Child, Not the Parents
Before getting into how agreements work, there is a foundational legal principle that shapes everything else: child support is not the custodial parent’s money to give up.
Every state treats child support as the legal right of the child. The custodial parent receives it on behalf of the child — they hold it in trust, they are not the owner. Courts have consistently held that neither parent has authority to waive a right that belongs to the child.
Florida’s official judiciary benchbook states this plainly: child support “is a right that belongs to the child and may not be contracted away by the parents. A custodial parent’s waiver of a child’s right to support is contrary to public policy and unenforceable by the courts because it is not in the best interests of the child.” That is not just Florida’s view — it reflects the baseline legal position confirmed by courts across the country, grounded in Florida Statutes §61.30 and parallel authority in every state discussed below.
Illinois makes this explicit in the Illinois Parentage Act: the state recognizes “the right of every child to the physical, mental, emotional and monetary support of his or her parents.” Under 750 ILCS 5/505, the right to support cannot be adversely affected by any parental agreement — including a premarital agreement.
Maryland’s Supreme Court addressed this directly in 2025. In In re Marriage of Houser, 490 Md. 592 (2025), both parents were found fit, had shared physical custody, and mutually agreed to withdraw child support as an issue. The circuit court rejected their agreement and ordered guideline support anyway. The appellate court affirmed. The Supreme Court of Maryland affirmed again — holding that child support cannot be waived or bargained away because the right belongs to the minor child, not to either parent. Even two fit, cooperative parents with shared custody cannot simply agree that support is off the table.
This matters because it reframes the entire question. When parents propose no child support, they are not waiving something they own. They are asking the court to approve a deviation from an obligation the law imposes for the child’s benefit. The court decides whether that deviation is acceptable.
Can Parents Agree to No Child Support? When Courts Will Approve It
Parents can reach their own agreement about child support — including an agreement that no support changes hands. But to be legally enforceable, that agreement must be submitted to a family court, incorporated into a court order, and approved by a judge who has reviewed whether it protects the child.
Texas Family Code §154.124 allows parents to enter a written agreement that varies from the guidelines, including agreements that eliminate support. Courts first calculate the presumptive guideline amount before considering any deviation — that baseline is what the judge measures the proposed agreement against. But the statute conditions everything: “If the court finds that the agreement is in the child’s best interest, the court shall render an order in accordance with the agreement.”
If the court finds the agreement is not in the child’s best interest, it can request a revised agreement or simply order guideline support on its own. The Texas Supreme Court confirmed this in Ochsner v. Ochsner (No. 14-0638): before entering any agreed child support order, the court must independently find the agreement serves the child’s interest — and it is not bound by what the parents decided.
When a court reviews a no-support proposal, it typically examines whether both parents have comparable incomes, whether parenting time is genuinely equal and expenses are split, whether the child’s health insurance and medical costs are covered by other arrangements, whether the custodial parent has sufficient independent resources to meet the child’s needs, and whether the agreement was reached freely without coercion. No court will sign off on an arrangement that risks leaving the child dependent on public assistance.
Take a situation where two parents share equal parenting time, both work full-time with similar incomes, and have agreed to split the child’s costs directly. A court reviewing this has a reasonable basis to approve zero support — both parents are genuinely contributing equally. Compare that to a situation where one parent earns $120,000 and the other earns $30,000. Even with 50/50 custody, courts in most states will still calculate support based on the income disparity. An agreement to pay nothing in that scenario is far harder to approve, because equal parenting time does not automatically eliminate child support.
The Five Declarations California Requires Before Any Agreement Goes Below Guideline
California has the most specific codified requirements for a below-guideline stipulation. Under California Family Code §4065, a court cannot approve any child support amount below the guideline formula unless both parents declare all five of the following in the stipulation: they are fully informed of their rights under the child support guidelines; the order is being agreed to without coercion or duress; the agreement is in the best interests of the children; the needs of the children will be adequately met by the agreed amount; and the right to support has not been assigned to the county — meaning neither parent receives CalWORKs, Medicaid, or other public assistance, and no application is pending.
Parents submit this through Judicial Council Form FL-350, which requires both parents to disclose their monthly income net of taxes and health insurance. The judge reviews the numbers before signing. California also builds in a one-way ratchet under §4065(d): if a below-guideline stipulation is approved, either parent can later seek modification back to full guideline support without needing to show a change in circumstances. The below-guideline arrangement is always reversible upward. A parent who agrees to zero support today has no protection if the other parent changes their mind next year and files for full guideline support. There is no requirement to show anything changed.
When IV-D Agencies Block a Private Agreement Entirely
There is a category of situations where no private agreement between parents — not even a court-approved one — can override the state’s interest in collecting child support. This happens when public benefits are or were involved. Federal law requires every state to maintain a child support enforcement program under Title IV-D of the Social Security Act — which means the IV-D agency’s authority to collect support exists independently of what any two parents decided between themselves.
When a family receives TANF, Medicaid, or other means-tested public assistance, the custodial parent must assign their right to child support to the state as a condition of receiving benefits. This assignment makes the state the legal owner of the child support debt. Once that happens, parents cannot agree to compromise or eliminate the obligation without the state also approving the arrangement.
Federal policy at the Office of Child Support Services confirms: child support judgments may be compromised by agreement of the parties — but judgments assigned to the state cannot be compromised without the state’s approval. The IV-D agency must also sign off, and it is not required to do so.
California hardwires this into the statute. Under Family Code §4065(c), a stipulated agreement for below-guideline child support is not valid unless the local child support agency co-signs it in any case where IV-D services are being provided. The agency cannot co-sign if the children receive CalWORKs or if a public assistance application is pending. This effectively blocks private zero-support arrangements in most IV-D cases without agency cooperation.
The practical implication: parents who believe they have a private deal may discover years later that the IV-D agency has been building an arrears case against the obligor the entire time. A handshake agreement between parents does nothing to bind the state.
The Informal Agreement Trap: Why a Notarized Document Is Not Enough
A lot of parents discover this too late: a notarized private agreement to skip child support has no legal force as a child support order.
Texas Family Code §154.124(c) is explicit: “Terms of the agreement pertaining to child support in the order may be enforced by all remedies available for enforcement of a judgment, including contempt, but are not enforceable as a contract.” Even a court-incorporated child support agreement is not enforceable as a contract — only as a court order. A private agreement that was never submitted to court is not even that. It is a piece of paper with no legal weight.
The same logic applies to verbal agreements, text message exchanges, and email chains where both parents confirm they agreed to no support. None of these create a court order. None of them protect the obligor from child support arrears. None of them give the obligee any legal mechanism to enforce anything if the arrangement falls apart.
The only thing that makes a child support arrangement legally binding is a court order signed by a judge.
Take a situation where two parents split up and agree via text message that no child support is needed — the mother earns well and tells the father not to worry about it. The father pays nothing for three years. When the child is enrolled in Medicaid, the IV-D agency opens a case automatically.
The agency calculates what guideline support would have been for those three years and enters the full amount as arrears — a judgment the court has no authority to reduce because it has already accrued. The text messages the father saved prove nothing. The mother’s informal agreement binds no one except herself, and it does not bind the state at all.
What Happens to Missed Payments Under an Unapproved Agreement
This is the section most people wish they had read before relying on an informal deal.
Under the Bradley Amendment — federal law at 42 U.S.C. §666(a)(9)(C) — every missed child support payment becomes a judgment by operation of law the moment it is due. No hearing required. No court action required. The debt exists automatically from the date the payment was missed.
Courts cannot retroactively reduce or eliminate those accrued judgments. A judge can change what the obligor owes going forward. The judge cannot touch what has already accumulated. This applies in every state without exception. It is not a state policy that can be varied by agreement — it is federal law.
Here is how this plays out. Say two parents agree informally that no child support is needed. The obligor pays nothing for two years. Then the relationship breaks down and the obligee opens a case with the IV-D agency. The obligor now owes two full years of back support at the guideline amount — every month, as a permanent judgment debt. The fact that the other parent agreed to no support is not a defense. The court has no authority to erase what has already accrued. Stop paying without getting a court order first, and every missed payment is already a judgment. Courts cannot undo the past.
The enforcement tools that follow unpaid arrears include Income Withholding Orders — automatic payroll deductions routed through the State Disbursement Unit — federal and state tax refund intercept, credit bureau reporting, driver’s license and professional license suspension, and passport denial once certified arrears exceed $2,500, a federal threshold set by the U.S. Department of State that applies uniformly in all 50 states. Federal law under PRWORA requires Income Withholding Orders in all child support orders entered after January 1, 1994 — meaning even in private cases not enforced by a state agency, an employer can be served with a withholding order the moment arrears are pursued.
The Consumer Credit Protection Act caps the amount that can be withheld at 50–65% of disposable earnings depending on arrearage status and whether the obligor supports a second family — but that ceiling is a limit on how much can be taken at once, not protection from the underlying debt.
An informal agreement offers zero protection against any of these consequences.
How States Handle No-Support Agreements Differently
The core rule — court approval required — is consistent everywhere. But the specific requirements and how strictly courts apply them vary meaningfully by state.
| State | Guideline Model | Court Approval Standard |
|---|---|---|
| Texas | Guideline ModelPercentage of Income | Court Approval StandardCourt must find the agreement is in the child’s best interest. Court may reject and order guideline support. Texas Family Code §154.124. |
| California | Guideline ModelIncome Shares | Court Approval StandardFive mandatory declarations required. IV-D agency must co-sign if services active. No changed circumstances needed to restore guideline support later. Family Code §4065. |
| New York | Guideline ModelIncome Shares (CSSA) | Court Approval StandardAgreement must state what the guideline amount would have been and the reason for deviation. Cannot be waived by either party or counsel. DRL §240(1-b)(h). |
| Florida | Guideline ModelIncome Shares | Court Approval StandardAny parental waiver is “contrary to public policy and unenforceable.” Deviation up to 5% allowed without written findings; beyond 5% requires written reasons. §61.30(1)(a). |
| Illinois | Guideline ModelIncome Shares | Court Approval StandardAny deviation requires written court findings stating what guideline amount would have been. Courts prefer “reserving” support over ordering zero. 750 ILCS 5/505(a)(3.4). |
| Colorado | Guideline ModelIncome Shares | Court Approval StandardCourt retains permanent jurisdiction regardless of any parental agreement. Either parent may seek support at any time based on current circumstances. C.R.S. §14-10-115. |
| Wisconsin | Guideline ModelPercentage of Income | Court Approval StandardPercentage applied to obligor’s gross income. Court must approve any deviation including zero support; written reasons required. Wis. Stat. §767.511. |
| Maryland | Guideline ModelIncome Shares | Court Approval StandardSupreme Court held in 2025 that parents cannot bilaterally waive child support — the right belongs to the child. Court rejected agreed waiver even where both parents were fit with shared custody. In re Houser, 490 Md. 592 (2025). |
One state variation worth noting separately: Illinois courts draw a legal distinction between a zero-dollar child support order and “reserving” child support. Under the Illinois Parentage Act at 750 ILCS 46/802(a), a judgment can explicitly reserve child support rather than set an amount — meaning no payments flow today, but the court keeps full jurisdiction to impose support later if circumstances change. Courts treat a reservation as more acceptable than ordering zero because it preserves the child’s access to future support without closing the issue. Parents pushing for zero support in Illinois may find “reserved” is the more realistic outcome a court will approve.
New York adds a procedural layer unique among states: under DRL §240(1-b)(h), any agreement deviating from the basic child support obligation must include written disclosure of what the guideline amount would have been and a written explanation for the deviation. This disclosure cannot be waived by either party or their attorneys. A stipulation that simply says “no child support” without those required disclosures will not be incorporated into a New York order.
How to Properly Submit a No-Support Agreement to the Court
The process varies by state but follows the same structure everywhere.
Start by calculating what the guideline amount would be. Federal law at 45 C.F.R. §302.56 requires every state to use child support guidelines as a rebuttable presumption. Before the court can approve any deviation, it needs to know what the guidelines would have produced. That calculation goes into the agreement itself, along with the explanation for why the agreed amount is nonetheless in the children’s best interests.
In California, this means completing the guideline calculation based on each parent’s monthly income net of taxes and health insurance and filing it on Form FL-350. In New York, it means stating the guideline amount in the written stipulation per DRL §240(1-b)(h). In Texas, it means putting the deviation in writing and submitting the agreement to the family court handling the case.
Both parents’ financial information goes before the judge before any order is signed. If the local IV-D agency is involved — because services were requested or because public assistance is or was received — the agency must be part of the process. Their refusal to co-sign in California is a dead stop. In other states, they must be notified and given an opportunity to object.
Once the judge reviews the agreement and signs it, it becomes a court order enforceable through all standard mechanisms: Income Withholding Orders issued to the obligor’s employer, contempt proceedings for non-compliance, and enforcement through the State Disbursement Unit. Payments ordered through income withholding are routed through the State Disbursement Unit before reaching the obligee — the obligor does not pay the other parent directly, and the SDU maintains a payment record that protects both parties. Without that signature, none of the agreement is binding on anyone.
Frequently Asked Questions
Can both parents agree to no child support?
Yes, but only if a family court approves the agreement and incorporates it into a court order. Parents cannot privately waive child support — the right belongs to the child, not to either parent. A court must find the arrangement is in the child’s best interest before it becomes enforceable. Without court approval, the agreement has no legal effect and the obligor remains exposed to full arrears under the Bradley Amendment.
Is a notarized child support agreement legally binding?
No. A notarized private agreement is not a child support order and cannot be enforced as one. Texas Family Code §154.124 makes this explicit: even court-incorporated child support agreements are enforceable only as court orders, not as contracts. A notarized document that was never submitted to and approved by a court has zero legal effect on child support obligations.
Can a mother waive child support?
No parent — mother or father — can waive child support on the child’s behalf. The right belongs to the child. A custodial parent who does not want support cannot legally surrender it because it is not theirs to surrender. Courts retain authority to order support regardless of what either parent claims to want, particularly if there is any risk the child may become reliant on public assistance.
What happens if we had an informal agreement and child support was never paid?
Every month of unpaid support is a judgment debt under the Bradley Amendment, 42 U.S.C. §666(a)(9)(C) — automatic, from the date payment was due. Courts cannot retroactively reduce what has accrued. The obligor owes the full back amount regardless of any informal agreement. The IV-D agency or the other parent can pursue collection through income withholding, tax intercept, license suspension, and all other enforcement tools.
Can you waive child support if you share 50/50 custody?
Equal parenting time reduces the support obligation in most Income Shares states but does not eliminate it automatically. Courts still compare incomes. If one parent earns significantly more, support is likely still owed even with equal time. Getting to zero requires a court finding that the children’s needs are fully met without any transfer — and that requires court approval, not just parental agreement. See Does 50/50 Custody Eliminate Child Support for a full breakdown.
Can the IV-D agency override a child support agreement between parents?
Yes — when public benefits are or were involved, the state is a party to the obligation. If support rights were assigned to the state as a condition of receiving TANF or Medicaid, the parents cannot agree to eliminate or reduce that obligation without the state’s approval. The IV-D agency can pursue the obligor for the full amount regardless of any private arrangement the parents made.
Can a no-support agreement be changed later if one parent changes their mind?
Yes, with minimal barriers. Under California Family Code §4065(d), if parents stipulated to below-guideline support, either parent can seek modification back to the full guideline amount without showing any change in circumstances. Most states treat below-guideline and zero-support agreements similarly — courts retain jurisdiction over child support indefinitely, and either parent can return to court at any time if the current arrangement no longer serves the child’s interests.
