What You Need Before You File for Child Support

Start with these documents before you contact the court

You will need to gather specific paperwork before you file. The exact list depends on whether you are the parent seeking support or the parent being asked to pay, and whether you already have a custody order in place. Most courts want to see proof of income, identification, and details about the child or children involved.

The fastest way to find out what your state requires is to call your local family court clerk's office directly — they handle these cases every day and can tell you in minutes what forms they need and whether your situation requires anything beyond the standard list. You can also visit your state court's website, which usually has a child support section with downloadable forms and checklists.

Key Takeaways

• You will need a birth certificate or custody order for each child, proof of your income, and a government-issued ID before you file.
• The other parent's current address and employment information speeds up the process, though the court can locate them if you do not have it.
• Your state's family court clerk can tell you in one phone call exactly which forms and documents your situation requires.
• If you cannot afford the filing fee, you can request a fee waiver using a form the court provides.
• Having your information organized in one place before you visit or call the court saves time and reduces the chance you will need to return with missing papers.

Documents you need about the child or children

Bring the original birth certificate or a certified copy for each child. If you do not have the original, you can request one from the vital records office in the state or county where the child was born — this usually takes one to two weeks and costs between $10 and $30 per copy.

If there is already a custody order, guardianship order, or divorce decree that names the children, bring that document too. The court needs to see it to understand the current arrangement and to know whether this is a new support case or a change to an existing one.

Proof of income and financial information

Bring recent pay stubs — usually the last two or three months — or tax returns if you are self-employed. If you receive unemployment, disability, Social Security, or other regular income, bring documentation of that as well. The court uses this to calculate how much support should be paid.

If you have no income or very low income, bring documentation of that too: a letter from an employer saying you were laid off, proof that you are in school, or a statement of your expenses if you are caring for another child or a dependent adult. Courts consider these circumstances when they set the amount.

Information about the other parent

If you know where the other parent works, their employer's name and address help the court locate them and verify their income. If you know their current address, write that down. If you do not have this information, the court has ways to find it — it takes longer, but it is not a barrier to filing.

If the other parent has already been ordered to pay support in another case, or if there is a protection order or custody restriction involving them, mention that when you file. The court needs to know about existing orders to avoid conflicts.

Your identification and contact information

Bring a government-issued photo ID — a driver's license, passport, or state ID card. Write down your current address, phone number, and email address. If you have moved recently or expect to move, tell the court; they need to be able to reach you about the case.

If you are using a different address for safety reasons — for example, if you have a protection order against the other parent — tell the court that too. Many courts have confidential address programs that keep your location private while still allowing the case to move forward.

The filing fee and fee waiver request

Most courts charge a filing fee to start a child support case, usually between $100 and $300 depending on your state and county. If you cannot pay this fee, you can file a request for a fee waiver at the same time you file your case. The form is called a "Motion to Waive Filing Fees" or "Affidavit of Indigency" — ask the clerk which name your court uses.

To get a fee waiver approved, you will need to show your income and expenses. Bring the same financial documents you are bringing for the support case itself. The court decides whether to waive the fee based on your income and household size.

How to organize and submit what you have

Make copies of everything before you go to the courthouse or mail it in. Keep the originals for your records. Put the copies in a folder or envelope in the order the court asks for — the clerk's office can tell you the order, or it will be listed on the form itself.

You can file in person at the family court clerk's office, by mail, or online if your state offers e-filing. Filing in person is fastest because the clerk can tell you immediately if something is missing and you can fix it on the spot. If you mail it in or file online, keep a copy of the receipt or confirmation number so you can track the case.

What happens after you file

Once you file, the court will send notice to the other parent. They have a set time — usually 20 to 30 days — to respond. If they do not respond, the court may set support based on what you have told them. If they do respond, there may be a hearing where both of you can present information about income and the children's needs.

The whole process from filing to a court order usually takes two to six months, though it can be faster if both parents agree on the amount. During this time, you can ask the court to order temporary support while the case is pending.

Frequently Asked Questions

What if I do not know where the other parent lives or works?

The court has investigators and databases that can locate the other parent. Tell the court what you do know — their last known address, previous employers, or family members' contact information. The case will take longer, but you can still file and move forward.

Do I need a lawyer to file for child support?

You do not need a lawyer, and many people file on their own. The court clerk can answer questions about forms and procedures. If the other parent hires a lawyer or if the case becomes complicated, you may want legal help — many legal aid offices offer free or low-cost help with child support cases.

Can I file if the other parent and I were never married?

Yes. You can file for child support whether you were married, in a domestic partnership, or never lived together. If there is no existing custody order, you may need to establish paternity or maternity first — the court can do this as part of the same case.

What if I already have a child support order and need to change it?

You file a separate request called a "Motion to Modify" or "Petition to Modify." You will need to show that circumstances have changed — a job loss, a significant income increase, or a change in custody. The process is similar to filing for the first time, but the forms are different.

Can I get child support while the case is pending?

Yes. You can ask the court for temporary support at the time you file or at any point before the final order. This is called "temporary" or "pendente lite" support. The court may order it based on the information you provide, even if the other parent has not yet responded.
