People owed child support who have an enforceable title can apply for the child support advance payment program. The removal of the income requirement applies to decisions made on or after October 29, 2026. Prepare your court documents and payment records and submit them to the Child Support Agency. The guidance does not specify a separate application deadline.
The amounts and requirements are based on the agency’s guidance checked on October 25, 2026, and the amended law.

When will the income limit for child support advance payments be removed?
The requirement that income be at most 150% of the standard median income will be removed on October 29, 2026. Whether the new rules apply depends on when the advance payment decision is made. Do not assume which rules apply based only on the application date.
| Change | Effective date | When it applies |
|---|---|---|
| Legal amendment based on the average amount of child support paid | April 28, 2026 | When an advance payment decision is made on or after the amendment takes effect |
| Removal of the requirement that income be at most 150% of the standard median income | October 29, 2026 | When an advance payment decision is made on or after the change takes effect |
The following is the wording on applicability in Article 2(2) of the supplementary provisions to the amended Act on Enforcing and Supporting Child Support Payment.
This applies to cases in which a decision on child support advance payments is made under the amended provisions of Article 21-7 on or after this Act takes effect.
The legal amendment concerning the average amount paid has already taken effect. Its effective date differs from the date the income requirement is removed. You can check the effective dates and applicability provisions in the Enactment and Amendment Text for Act No. 21600.
Application requirements that remain after the income requirement is removed
Even after the income requirement is removed, child support claims and payment status will still be reviewed. An enforceable title is a legal document that provides the basis for compulsory enforcement. Examples include a record of child support obligations or a judgment.
| Item to check | What to prepare |
|---|---|
| Child’s age | Confirm that you are actually raising a child aged 18 or younger |
| Claim for regular payments | An enforceable title specifying the child support amount, payment schedule, and person responsible for payment |
| Amount actually received | Check whether the average monthly amount paid during the 3 months immediately before the application month is less than the advance payment amount |
| Efforts to secure payment | Proof of an application for legal assistance or debt collection support, or of related proceedings in progress or completed |
Receiving some child support does not, by itself, exclude you from applying. You must compare the average monthly amount actually received with the advance payment amount. Rules provide for converting payment arrangements that are not monthly into monthly amounts.
If you do not have an enforceable title, first seek a legal assistance consultation with the agency. Having a judgment and providing proof of efforts to secure payment are separate matters. The agency’s FAQ states that filing only a request to change child support does not count as proof of such efforts. You can find details in the Agency FAQ.
Documents for child support advance payment applications
Prepare the application form, court documents, payment records, and proof of efforts to secure payment. The list below follows the agency’s published document submission guidance. Guidance issued before the change takes effect still contains the previous income limit. When you apply, check the latest forms and any requests for additional documents.
| Document | Preparation requirements |
|---|---|
| Application form and consent form for sharing administrative and personal information | 1 copy, signed or sealed |
| Personal information consent form | Include the signatures or seals of the applicant and household members as instructed |
| Enforceable title | 1 copy of the relevant document, such as a record of child support obligations, judgment, or mediation record |
| Certificate of service and certificate of finality | 1 copy of each, or a combined certificate |
| Proof of unpaid child support | Transaction records for the account designated to receive payments, covering the 3 months immediately before the application month |
| Proof of efforts to secure payment | A certificate confirming receipt of an application for legal assistance or debt collection support, a related court decision, or similar documents |
If you do not consent to information sharing, you may be asked to provide documents concerning family relationships. A copy of your bankbook may also be required depending on the circumstances. Check the detailed list in the Agency’s Document Submission Guide.
What if I do not have the service or finality documents?
Ask the service counter at the court that handled your case whether the documents can be issued. In certain cases, the agency accepts the My Case Search screen as an alternative. The general submission guidance requires a screen showing the date of receipt and the date the decision became final. For cases in which a certificate of finality cannot be issued, check the alternative documents listed in the Documents FAQ.
