Child Support Enforcement
The Other Parent Stopped Paying Child Support and Cannot Be Located—What Can You Do?
When child support stops, the financial pressure can become immediate. The situation may feel even more overwhelming when the other parent has moved, mail is being returned, service attempts have failed or an enforcement hearing is approaching.
You may be wondering how the case can move forward, what information the child-support agency needs and what documents you should bring to court.
This guide explains how to organize unpaid-payment records, address information, service attempts and questions for the child-support agency or court. It provides general educational information and is not legal advice.
An Unknown Address Does Not Automatically End Enforcement
Start With the Current Child-Support Order
Before focusing on enforcement, locate the complete current order.
- Current child-support order
- Date the order became effective
- Regular payment amount
- Payment frequency
- Retroactive-support terms
- Arrears balance, if stated
- Payment method required by the order
- Income-withholding provisions
- Previous modification orders
- Previous enforcement or violation orders
- Upcoming hearing notice
- Filed violation or enforcement petition
- Proof of any prior service attempts
Compare Payments to the Written Order
Build a Complete Payment History
Create a clear record showing what was ordered, what was received and what appears unpaid.
| Due Date | Amount Due | Amount Received | Payment Source | Balance | Supporting Record |
|---|---|---|---|---|---|
| Jul 1, 2026 | $400 (per order) | $0 | — | $400 unpaid | Agency ledger / bank statement |
| Aug 1, 2026 | $400 (per order) | $0 | — | $800 unpaid | Agency ledger |
| Sep 1, 2026 | $400 (per order) | $100 | Cash App | $1,100 unpaid | Cash App receipt |
Documents that may support your payment history:
- Official child-support account statement
- Court or agency payment ledger
- Bank statements
- Payment-app records
- Cancelled checks
- Money-order receipts
- Payroll withholding records
- Written communications discussing payment
- Records showing direct payments not included in the agency ledger
Record Direct Payments Separately
What If Mail Was Returned or the Address Is Unknown?
Returned mail should be preserved because it may document an unsuccessful attempt to reach or serve the other parent.
- The returned envelope
- The address used
- The date mailed
- The postal notation
- Copies of the documents sent
- Any affidavit or declaration from the process server
- Dates and results of every service attempt
- The last verified address
- When the parent reportedly moved
- The source of any new location information
- Communications in which the other parent discussed moving
- Information already provided to the child-support agency
Label the Source of Each Address
Information That May Help Locate the Other Parent
A government child-support agency may request identifying information. Provide only information obtained lawfully.
- Full legal name
- Prior names or aliases
- Date of birth
- Last known address
- Previous addresses
- Telephone numbers
- Email addresses
- Known employer or occupation
- Previous employer
- State where the person may currently live
- Names of known businesses
- Vehicle information already lawfully known
- Known professional licenses
- Names and contact information for attorneys previously involved
- Existing court-case numbers
- Copies of prior identification information already contained in court or agency records
Do Not Obtain Protected Records Unlawfully
What If the Other Parent Does Not Have a Social Security Number?
A Social Security number can help identify a person, but it is not the only identifying information that may exist. A child-support agency may ask for a combination of information such as the parent’s full name, date of birth, prior address, employer, case number, telephone number or other information already contained in government records.
The absence of a known Social Security number does not prove that the parent cannot be located or that the support order cannot be enforced. However, it may affect which automated tools produce results.
Questions to ask the agency:
- What identifying information is currently in the case file?
- Is the date of birth confirmed?
- Are prior addresses documented?
- Has a state parent-locator request been made?
- Is an interstate location request appropriate?
- What additional information would help distinguish this person from others with a similar name?
- Is any identification number already contained in prior court filings?
No search method is guaranteed to locate the parent. Confirm available options with the agency handling your case.
When the Other Parent Moves to Another State
Child-support agencies regularly work with cases involving parents in different states. The state that issued the order and the state where the other parent lives may coordinate regarding location, service, enforcement or other case activity.
- State and county that issued the order
- Current child-support agency handling the case
- State where the other parent may be living
- Existing case and account numbers
- Payment and arrears history
- Returned-mail records
- Last known employer
- Previous enforcement activity
- Upcoming court dates
Moving Does Not Erase the Obligation
Ask About Official Parent-Location Resources
Federal and state child-support programs have systems that may assist agencies with locating parents for child-support purposes.
- Has a parent-location request been opened?
- Is the State Parent Locator Service available?
- Can the agency use interstate child-support procedures?
- Does the agency need more identifying information?
- Has any employment information been located?
- Has the case been referred to the state where the parent may reside?
- Who is the assigned worker?
- When should the parent follow up?
- Can the agency provide written confirmation of the case status?
The parent may not receive access to confidential databases or protected address information. The agency may use information internally without releasing it directly.
What If You Cannot Complete Service?
Courts have specific rules governing how enforcement papers must be served. The correct method may depend on the state, type of case, documents being served and previous service attempts.
If ordinary service fails, ask the court clerk, self-help center or licensed attorney:
- Was the service attempt properly documented?
- Does another attempt need to be made?
- Who is legally permitted to serve the documents?
- Can the child-support agency assist with service?
- What proof of unsuccessful service is required?
- Is a request for an alternative service method available?
- Does alternative service require advance court approval?
- Will the hearing proceed, be rescheduled or be limited if service is incomplete?
- What must be filed before the hearing?
Do Not Choose an Alternative Service Method on Your Own

Create a Child-Support Enforcement Timeline
A timeline helps connect each event to the document that supports it.

|---|---|---|---|---|
| Dec 17, 2025 | Retroactive payments were scheduled to begin | Existing support order | Filed order | Establishes the reported start date. |
| Jul 30, 2026 | Payment was not received | Agency ledger | Payment statement | Helps calculate the reported unpaid balance. |
| Aug 18, 2026 | Papers were returned by mail | Postal service | Returned envelope | Documents an unsuccessful mailing attempt. |
| Aug 25, 2026 | Parent reported possible residence in another state | Source must be identified | Message or other record | May help the agency evaluate an interstate location request. |

Questions to Take to the Child-Support Agency
Bring a written list of questions so nothing is missed.
- What is the official arrears balance?
- Are retroactive payments included?
- What address is currently listed?
- What proof is needed to update the address status?
- Can the agency initiate a location request?
- Can the agency coordinate with another state?
- What identifying information is missing?
- Who is responsible for completing service?
- What happens to the upcoming hearing if service is incomplete?
- What records should I bring?
- Can I receive a written case-status summary?

- Is there free or reduced-cost legal help?
When Financial Need Is Immediate
Enforcement proceedings may take time and may not provide immediate funds. If the children’s immediate needs are at risk, local government or nonprofit organizations may be able to help.
Consider asking about:
- Food assistance
- Emergency rental or utility assistance
- Disability-related family services
- School-based family resources
- Benefits for children with disabilities
- Local legal-aid organizations
- Language-access assistance
- Court self-help services

Notice
Are You Trying to Prepare for a Child-Support Hearing?
If payments have stopped, the other parent cannot be located or your hearing is approaching, start by telling us what has happened.
Your intake helps The Case Advocates understand:
- Where the order was issued
- Whether another state is involved
- What payments are reportedly unpaid
- What service attempts have been made
- Which documents you currently have
- When your next hearing is scheduled
- Which questions remain unanswered
Submitting an intake does not create an attorney-client relationship, does not begin legal representation and does not guarantee acceptance of services.
Frequently Asked Questions
Can child support be enforced if the other parent moved?
Moving to another state does not automatically end a child-support obligation. Child-support agencies in different states may coordinate on location, service, and enforcement. The exact process depends on the order, the states involved, and the current case status. Confirm the specific procedure with the agency handling your case or a licensed attorney.
What happens when the other parent cannot be served?
Courts have specific rules for how enforcement papers must be served. If ordinary service fails, the court may allow another attempt, agency assistance, or an alternative service method if the rules permit it. Ask the court clerk, self-help center, or a licensed attorney what proof of unsuccessful service is required and whether alternative service is available in your jurisdiction.
Can the child-support agency help locate a parent?
Federal and state child-support programs have parent-location systems that may help agencies locate parents for child-support purposes. You can ask the agency whether a parent-location request has been opened and what additional identifying information would help. The agency may use information internally without releasing protected address details to you directly.
What if I do not know the other parent’s Social Security number?
A Social Security number can help identify a person, but it is not the only identifying information that may exist. An agency may use a combination of name, date of birth, prior address, employer, case number, or other information already in government records. The absence of a known Social Security number does not prove the parent cannot be located or the order cannot be enforced, though it may affect which automated tools produce results.
What proof should I keep when mail is returned?
Preserve the returned envelope, the address used, the date mailed, the postal notation, copies of the documents sent, and any affidavit from the process server. Keep a record of every service attempt and its result. Returned mail may document an unsuccessful attempt to reach or serve the other parent.
Can I personally search for the other parent’s address?
You may give the agency information you already possess, but do not impersonate another person, access private accounts, use false pretenses, trespass, threaten relatives, or attempt to obtain protected motor-vehicle, employment, or financial records unlawfully. Give the information you already have to the agency, court, or licensed attorney and ask what official location resources are available.
How do interstate child-support cases work?
Child-support agencies regularly work with cases involving parents in different states. The state that issued the order and the state where the other parent lives may coordinate regarding location, service, enforcement, or other case activity. The exact process depends on the order, the states involved, and the current case status. Confirm the details with the agency handling your case.
What should I bring to a violation hearing?
Organize the current support order, modification orders, the violation or enforcement petition, the hearing notice, filed proof of service, the official payment ledger, personal payment records, returned mail, process-server reports, and any communications about the move or the agency. Prepare a list of questions for the agency or your attorney. Confirm local requirements with the court or a licensed attorney.
Can I use screenshots or social-media posts to prove where someone lives?
A suspected address and a verified address are not the same. Screenshots or social-media posts may suggest a possible location, but whether they are sufficient depends on the rules of the court or agency. Clearly label where each piece of information came from and let the agency, court, or licensed attorney determine how it should be used.
Can The Case Advocates represent me in court?
No. The Case Advocates is not a law firm. The Case Advocates does not provide legal advice, cannot serve legal documents, cannot represent clients in court, and cannot guarantee collection, service, enforcement, or any legal outcome. Services focus on factual record organization, case preparation, and helping clients understand what information they have and what questions need to be answered.
