Are you looking for a paternity lawyer in Lake Forest, IL?
At Hurst, Kay, Allen & Stambler, LLC, we serve clients in Lake Forest paternity matters with over 100 years of combined legal experience.
If you are raising a child with someone you didn’t marry, the law does not automatically treat both of you as parents. Parentage has to be established first. Until it is, neither parent can ask a court for a parenting schedule or a child support order.
Our firm limits its practice to family law, and our attorneys bring over a century of combined experience to parentage disputes. We represent mothers and fathers, and we take cases from both sides. Talk to a Lake Forest, IL paternity lawyer before you sign a form or agree to an arrangement informally.
Paternity Lawyer Lake Forest, IL
Illinois recorded 124,871 births in 2023, and 49,538 of them were to unmarried mothers, according to Illinois vital statistics. That is nearly four in ten children born in this state each year. Lake County produces a steady share of those cases, and they are heard in Waukegan.
A paternity attorney handles the legal process of confirming who a child’s parents are and what rights and duties come with that status. The work covers acknowledgement forms signed at the hospital, court petitions to establish parentage, genetic testing disputes, and challenges to an acknowledgment that turned out to be wrong. Our Lake Forest paternity lawyers also handle what comes after the parentage order, because that order settles only the question of who the parents are.
Types of Paternity Cases We Handle in Lake Forest
Paternity work splits into two categories. The first is getting parentage legally recognized. The second is deciding the rights and obligations that follow. Our attorneys handle both.
- Establishing parentage. Most cases start here. We prepare and file petitions in the Lake County Family Division, and we advise parents on whether a signed acknowledgment or a court order better fits their circumstances.
- Child custody. Illinois calls this the allocation of parental responsibilities, which covers decision-making authority over school, medical care, and religion, along with parenting time. We negotiate and litigate those allocations for clients throughout Lake Forest.
- Visitation rights. A newly recognized father often starts with no schedule at all. We prepare parenting time proposals that a judge can enter as an order and that fit a child’s school and activity calendar.
- Child support. Support obligations attach once parentage is established, and they can run in either direction depending on which parent has the child most of the time. Our attorneys handle initial support orders, modifications, and enforcement.
- Disputed parentage. Some cases turn on genetic testing, on a father whose name never made it onto the birth certificate, or on a man who denies he is the parent. We handle contested proceedings from the first filing through trial.
- Parentage fraud and disestablishment. A man who signed an acknowledgment based on false information has options, but they are narrower than most people assume and they close with time. We bring and defend disestablishment claims in Lake County.
- Adoption. A stepparent adoption cannot move forward until the legal father’s rights are resolved one way or the other. Our firm handles stepparent, agency, independent, and international adoptions.
- Family dispute mediation. Parents who agree on parentage but not on the schedule can often resolve the rest without a hearing. We mediate parentage disputes, and we represent parents in mediation conducted by someone else.
- Domestic Violence. Parentage cases sometimes involve allegations of abuse or threats. We petition for protective orders, and we defend against petitions filed to gain an advantage in a parenting dispute.
- Collaborative law. Both parents and both attorneys sign an agreement to resolve the matter without going to court. It works well when the parents expect to share parenting responsibilities for years and want to keep the details out of a public court file.

Understanding Paternity Cases
Establishing Parentage and Parental Rights in Illinois
Illinois gives families more than one route to legal parentage, and which route applies depends on the facts rather than on preference.
- Voluntary acknowledgment. Both parents sign a form at the hospital, and it is filed with the state.
- Administrative order. The state child support agency can establish parentage without anyone appearing before a judge.
- Court order. Either parent files a petition, and a judge decides the question.
- Genetic testing. A court orders testing when the parties disagree about who the biological father is.
Legal parentage controls decision-making authority, parenting time, child support, inheritance, and eligibility for a parent’s health insurance.
What Are Important Aspects of a Paternity Case?
Two separate questions drive most parentage matters. The first is how the child’s legal status gets established. The second is what each parent is entitled to afterward. The two are frequently handled through different filings.
- Whether an acknowledgment already on file is valid
- Whether genetic testing is needed, agreed to, or being refused
- How much time has passed since the child’s birth
- Whether another adult already holds legal parent status and has to be brought into the case
- What parenting schedule the child is living under right now
Courts pay close attention to that last point. A schedule that has been working informally for a year carries real weight with a judge. A father who has been involved since birth is in a different position than one who files years later.
What Is The Paternity Case Timeline?
Uncontested matters can move quickly. Contested ones move at the pace of the Nineteenth Judicial Circuit’s docket.
- Filing. A petition to establish parentage goes to the circuit clerk.
- Service. The other parent is served with the petition and given time to respond.
- Testing. If parentage is disputed, the court orders genetic testing.
- Case management. The judge sets deadlines for discovery and financial disclosure.
- Entry of the order. Parentage is established, and the case turns to parenting time and support.
Most matters settle somewhere in the middle of that sequence. Settlement requires both sides to be working from the same financial and scheduling information, which is why discovery still matters in a case that never reaches trial.
