How to File for a Modification
1
Gather documentation. Collect proof of changed circumstances: pay stubs, tax returns, medical records, custody agreements, or termination letters.
2
File a motion with the court. Submit a petition or motion for modification with your local family court. Many states have standardized forms available online.
3
Serve the other parent. The other parent must be formally notified (served) with copies of the motion and supporting documents.
4
Attend the hearing. Both parents present their case. The judge reviews the evidence and applies state guidelines to determine if modification is warranted.
Typical Timeline
- • Filing to hearing: 4–12 weeks
- • Agreed modifications: 2–6 weeks
- • Contested cases: 3–6 months
- • New order effective: usually from filing date
Do You Need a Lawyer?
- •Simple cases: You can file pro se (without a lawyer) using court forms
- •Agreed modifications: Often handled without attorneys if both parents agree
- •Complex cases: Recommended when income is disputed, custody is contested, or assets are involved
- •Legal aid: Many states offer free legal help for low-income parents
General guidance only — not legal advice. Consult a family law attorney for your specific situation. Do not change your support amount without a court order.
