To report child support fraud, contact your state or local child support enforcement agency, which you can locate through the federal Office of Child Support Services directory at acf.gov.1Administration for Children and Families. State and Tribal Child Support Agency Contacts These agencies take intake by online form, phone hotline, or mailed complaint, and they have the authority to investigate financial disclosures, enforce orders, and refer cases for prosecution. Whether your report gets acted on depends almost entirely on the specifics and documentation you bring with it.
Know Whether What You’re Seeing Is Actually Fraud
Child support fraud means a parent deliberately misrepresents income, employment, assets, or living arrangements to manipulate a support obligation. It is not the same as a parent falling behind because they lost a job or missed a payment.
On the paying-parent side, the pattern is almost always making income look smaller than it is. Common versions include hiding cash earnings, side jobs, freelance work, or bonuses that never appear on court disclosures. Some parents quit a well-paying job or take a deliberately lower-paying one to shrink the support calculation. Courts can respond by imputing income based on what the parent could realistically earn given work history, education, skills, and the local job market. A parent who was earning $80,000 and suddenly reports $30,000 after a support order will face skeptical questions from a judge.
Asset shuffling is the other common tactic: signing a car title to a relative, moving money into someone else’s account, or parking property in a business partner’s name while still using and controlling it. Courts weigh timing (did the transfer happen around a support dispute), continued use of the property, and whether the parent received anything close to fair value.
Fraud runs the other direction too. A custodial parent may fail to report a new job, a live-in partner’s income, or other household earnings that affect the calculation, or may misrepresent where the child primarily lives and who provides day-to-day care. Because financial disclosures are made under oath, false information can bring perjury exposure on top of any fraud consequences.
Gather Your Evidence Before You File
Agencies get a lot of complaints. The ones that get investigated are the ones with concrete details rather than suspicions. Pull together as much of the following as you can before you submit anything:
- Identifying information: the person’s full legal name, last known address, employer name and address, and the child support case number tied to the existing order.
- A specific description of the conduct. “He’s working under the table” is a starting point. “He has been doing electrical work for [Company Name] at [Address] since March and getting paid in cash” is what an investigator can act on. Include dates.
- Supporting documents: copies of pay stubs, bank statements, tax records, or any paperwork showing income or assets that weren’t disclosed. Screenshots of social media posts showing expensive purchases, vacations, or a lifestyle inconsistent with the claimed finances are also useful. Most jurisdictions treat social media posts as admissible when relevant and properly authenticated.
- Witnesses: names and phone numbers of anyone who can confirm undisclosed employment, hidden income, or misrepresented living arrangements.
Save screenshots with timestamps rather than assuming the posts will stay up. If someone deletes posts after learning they’re under investigation, that can be treated as destruction of evidence. Do not create fake accounts or access private profiles you weren’t invited into. Evidence obtained through deception or unauthorized access can be thrown out and may create legal problems for you.
Where to File
Your State or Local Child Support Enforcement Agency
This is the right starting point for nearly every case. State and local agencies enforce support orders, investigate disclosures, and refer cases for criminal prosecution when warranted. Most have online reporting forms that walk you through the required details; many run dedicated fraud hotlines where you can speak with an intake specialist. You can also mail a written complaint. If you’re not sure which agency handles your case, the federal Office of Child Support Services keeps a directory of every state and tribal agency.1Administration for Children and Families.

Anonymous reporting is available in some places, but including your contact information helps investigators follow up with clarifying questions, and reports with a name attached tend to get more attention.
Federal Channels (Narrow Uses Only)
Federal involvement is limited. The Department of Justice handles cases where a parent willfully fails to pay support for a child living in another state, or where a parent crosses state lines to evade a support obligation. Child support matters must first be addressed at the state or local level before federal concerns can be raised.2United States Department of Justice. Citizens Guide To U.S. Federal Law On Child Support Enforcement
The HHS Office of Inspector General accepts tips about fraud, waste, and abuse in federal child support enforcement programs through its hotline. That channel is relevant when the fraud involves manipulation of the enforcement system itself rather than one parent hiding income from the other.3Office of Inspector General.

What Happens After You Report
An enforcement officer reviews the allegation and decides whether the information is credible enough to open a full investigation. If it moves forward, investigators can contact employers, subpoena financial records, run data matches with banks and tax records, and use other tools to verify concealed income or assets.
Don’t expect a play-by-play. Privacy laws prevent agencies from sharing investigation details or outcomes with the reporting party in most cases. Timelines vary widely with complexity and caseload. A straightforward situation where an employer can confirm undisclosed wages moves faster than one involving self-employment income or assets scattered across multiple accounts.
If investigators confirm fraud, outcomes typically include a modified support amount reflecting actual income, an order to pay all back support owed, contempt of court proceedings, and in serious cases, criminal charges. A court can hold a parent in civil contempt for failing to comply with a support order, which can result in probation or jail time, but only after the court determines the parent actually has the ability to pay. If no evidence of fraud turns up, the case is closed.
What Reporting Costs
Filing a report with a state agency or federal hotline costs nothing. If the investigation leads to a support modification hearing, you may face court filing fees that vary by jurisdiction. Building a stronger evidence package before you report is optional: private investigators who document hidden income or employment typically charge between $60 and $300 per hour depending on your location and the complexity of the work. Some family law attorneys offer consultations to help you organize evidence and understand what your state’s agency will want to see. Weigh those costs against the potential increase in support payments if the fraud is confirmed.
Protect Yourself From a False-Report Backfire
Stick to facts you can document. Exaggerating or fabricating allegations backfires badly. Filing a knowingly false report can expose you to penalties for making false statements and can damage your credibility in any ongoing custody or support proceedings. Judges have long memories for parties who weaponize the enforcement system. If you’re not sure whether what you’ve observed rises to fraud, a consultation with a family law attorney can help you tell suspicious behavior from actionable misconduct before you file.
Keep copies of everything you submit. If the agency doesn’t act and you believe your evidence is strong, ask about escalation procedures within the agency, or talk to an attorney about filing a motion to modify support directly with the court. The system works, but it works faster when you’ve done the homework first.
