Establishing Paternity in Indiana: A Comprehensive Guide for Unmarried Fathers

Current as of: September 27, 2026 Paternity & Fathers' Rights Indiana
👨‍👦
In Indiana, unmarried fathers must legally establish paternity to secure custody or visitation rights. You can do this voluntarily by signing a Paternity Affidavit at the hospital or through a court order requiring DNA testing. Court filing fees generally range from $157 to $177.

When a child is born to unmarried parents in Indiana, the law does not automatically recognize the biological father's legal rights. Without establishing paternity, a father cannot seek custody, enforce parenting time, or make critical legal decisions for the child. Furthermore, the child may be missing out on vital benefits, such as health insurance, inheritance rights, and child support. Establishing paternity is the essential first step in protecting your bond with your child.

This process can be emotional and legally complex, depending on whether both parents agree. Whether you live in Indianapolis, Fort Wayne, or Evansville, the procedures remain largely the same across the state. If you are facing challenges in establishing your fatherhood, you can easily find and hire a qualified local lawyer from our US Attorneys directory to guide you through the local court system.

The Legal Effect of Signing the Paternity Affidavit

In Indiana, the most straightforward way to establish paternity is by completing a voluntary affidavit. If both parents agree who the biological father is, they can sign Form 44780, Indiana, Department of Health, Paternity Affidavit. This document is typically provided at the hospital immediately after the child's birth, but it can also be completed later at the local health department.

By signing this form, the man acknowledges he is the biological father, and his name is added to the birth certificate. Under Ind. Code § 31-14-7-3, a properly executed Paternity Affidavit establishes paternity conclusively without the need for court involvement. However, signing this document is a serious legal commitment. It legally obligates the father to support the child financially and opens the door for custody and parenting time requests.

How to Contest Paternity After Signing

Sometimes, a man may sign the Paternity Affidavit but later develop doubts about his biological relationship to the child. Indiana law provides a very narrow window to contest this document. According to state statutes, a man has only 60 days from the date of signing to request a DNA test to rescind the affidavit. Once the 60-day window closes, challenging paternity becomes exceptionally difficult.

If the 60 days have passed, you must file a formal petition to set aside the affidavit in a local court, such as the Marion County Circuit Court, Indianapolis or the Allen County Superior Court, Fort Wayne. To succeed, you generally must prove that your signature was obtained through fraud, extreme duress, or a significant mistake of fact. Because the burden of proof is high, working with a local attorney is highly recommended.

Genetic Testing Procedures in Indiana Courts

If the mother refuses to sign the Paternity Affidavit, or if the identity of the biological father is disputed, a paternity lawsuit must be filed. When a petition is filed under Ind. Code § 31-14-4-1, the court will typically order genetic testing. Either the mother, the presumed father, or the state (if state aid is involved) can request this test.

The court-ordered DNA test involves a simple cheek swab from the mother, the child, and the alleged father. The samples must be collected and analyzed by an accredited laboratory to ensure a strict chain of custody. If the results show a 99% or higher probability of paternity, the court will issue an official order declaring the man as the legal father. You might be ordered to complete this process through agencies like the Department of Child Services, Indianapolis.

Step-by-Step Process to Establish Paternity in Indiana

If you cannot establish paternity voluntarily at the hospital, you will need to navigate the Indiana court system. Here is the general process for unmarried fathers:

Step 1: File the Paternity Petition

You must prepare and file a Petition to Establish Paternity in the juvenile or family division of the court in the county where the mother or child resides. You will submit these documents to the clerk of the court, for instance, at the Lake County Superior Court, Crown Point.

Step 2: Serve the Mother

After filing, you are legally required to notify the mother. This is called 'service of process.' You can accomplish this via certified mail, through the local sheriff's department, or by using a private process server. The mother will then have a specific timeframe to respond to your petition.

Step 3: Attend the Initial Hearing

The court will schedule an initial hearing. If both parties agree on paternity, the judge may enter an order that day. If there is a disagreement, the judge will typically order genetic testing. You must comply with the testing deadlines set by the court.

Step 4: Final Hearing and Orders

Once the DNA results are returned and confirm paternity, the court will hold a final hearing. During this hearing, the judge will issue the final Order Establishing Paternity. Simultaneously, the court usually addresses related matters, such as child support calculations, custody arrangements, and parenting time based on the Indiana Parenting Time Guidelines.

How Much Does it Cost in Indiana?

The costs associated with establishing paternity can vary depending on the county and whether the case is contested. Common expenses include:

  • Court Filing Fees: Typically range from $157 to $177 when filing a new civil action in Indiana courts.
  • Service of Process: Sheriff service usually costs around $28, while a private process server may charge between $50 and $100.
  • DNA Testing: Court-admissible genetic testing generally costs between $200 and $500. The court may order the alleged father to pay this cost initially, but it can be reallocated based on the results.
  • Lawyer Fees: Hiring an attorney can range from $1,500 to $5,000+ depending on the complexity of the case.

How Long Does the Process Take?

If you establish paternity voluntarily by signing the affidavit at the hospital, the process is instantaneous. However, if you must go through the court system, it generally takes longer. An uncontested paternity case where both parties cooperate with DNA testing might be resolved in 2 to 3 months. If the case is highly contested, involving disputes over custody and support, the process can easily stretch from 6 months to over a year.

Frequently Asked Questions (FAQ)

Do I automatically get custody if I establish paternity?

No. Establishing paternity simply gives you the legal right to ask for custody or parenting time. Custody decisions are based entirely on what the court deems is in the best interests of the child.

Is there a statute of limitations for filing a paternity case in Indiana?

Under Ind. Code § 31-14-5-3(b), a mother or an alleged father must file a paternity action not later than two (2) years after the child is born, unless specific exceptions apply (such as voluntary support payments, written acknowledgment, or a joint waiver). The extended deadline allowing an action before the child reaches age 20 under Ind. Code § 31-14-5-2(b) applies exclusively when the petition is filed by the child.

Can I stop paying child support if the mother denies me visitation?

No. Under Indiana law, child support and parenting time are considered separate legal issues. Withholding child support because you are denied visitation can result in severe legal penalties, including being held in contempt of court.

Can I get a court-appointed lawyer for a paternity case?

In most civil paternity cases, you are not guaranteed a free court-appointed attorney. You will likely need to represent yourself or hire a private family law attorney to protect your rights.
