Naperville paternity attorneyUnder Illinois law, the legal relationship between a child and his or her father is only presumed if the man was married to child’s mother at the time of, just prior to, or just after the child’s birth. According to the most recent available statistics from the Centers for Disease Control and Prevention, however, more than 40 percent of all births in the United States are to unmarried mothers. These numbers indicate that, on average, paternity cannot be presumed in about two out of five cases.

The most common method for establishing paternity when there is no existing presumption—or to rebut a presumption in certain cases—is by means of a voluntary acknowledgement of paternity (VAP) form. When both the mother and father complete the form properly, it creates a legal parent-child relationship between the man and his son or daughter. As such, completing the VAP form is an extremely serious matter, and one that should not be taken lightly.

Be Absolutely Certain

Prior to acknowledging paternity voluntarily, it is important that there is no doubt in your mind that you are the child’s father. Once the form has been completed and the time period for rescinding the acknowledgment has passed, you are the child’s father in the eyes of the law. If, down the road, you become aware that you might not be the child’s biological father, it may be too late.


DuPage County family law attorneyIf a woman in Illinois who is married to a man has a child, her husband is automatically presumed to be the child’s biological father. The father will not need to take additional action to establish himself as the child’s legal parent. When unmarried parents have a child together, the father is not automatically considered the legal father until he takes certain steps. Many people falsely assume that a father can gain legal parentage of a child by simply writing his name on the child’s birth certificate. However, before a father can be listed on a child’s birth certificate, he must establish paternity. Depending on the circumstances, DNA testing may be necessary to establish the biological relationship between a child and the child’s presumed father.

Establishing Legal Parentage of a Child

There are three ways that an Illinois parent can establish paternity. If both parents agree that the father is indeed the child’s biological father, the parents can sign a Voluntary Acknowledgement of Paternity (VAP) and file it with the Illinois Department of Healthcare and Family Services (HSF). The VAP form is typically available at the hospital when the baby is born, or it may be obtained through the HSF website, local child support office, County Clerk’s Office, or local Registrar’s office.

If either parent questions the presumed father’s biological relationship with the child, the process for establishing paternity is more complex. In this situation, paternity may be established via an Administrative Paternity Order through the HFS Division of Child Support Services or through an Order of Paternity entered by the court.


DuPage County family law attorneysChild custody and parentage issues can become more complicated when parents are unmarried. Illinois law assumes that the husband of a woman who gives birth is the father of that child. However, an unwed father is not presumed to be the child's biological parent. Fathers who want to become their child’s legal parent must establish parentage. After parentage is established, the father enjoys parental rights and gains certain legal duties to the child.

Benefits of Establishing Parentage

There once was a time when unwed parents were ostracized. Now, about 40 percent of children are born to unmarried mothers according the Centers for Disease Control and Prevention (CDC). When unmarried parents have a child, a legal relationship between the child and his or her father must be established before a court will order child support. Establishing paternity not only makes the parental relationship official, but also provides the child with emotional and financial support from their noncustodial parent including:

  • Essential communication and relationships with both parents;
  • Child support and federal benefits including Social Security benefits; and
  • Health insurance benefits.

Methods for Establishing Paternity in Illinois

There are several methods unmarried Illinois parents can use to establish parentage. A court an enter an Order of Paternity, parents can complete a Voluntary Acknowledgement of Paternity (VAP) document, or the Illinois Department of Healthcare and Family Services can enter an Administrative Paternity Order. After parentage is legally established, either parent may be required to pay the other child support. It is important to note that establishing parentage with a VAP or Administrative Paternity Order does not automatically guarantee custody or visitation. Issues of parental responsibility and parenting time are decided by the courts.


DuPage County family law attorneyThe allocation of parental responsibilities, commonly called child custody, can be a complicated part of family law. When a couple who is unmarried has a child, there are different rights and responsibilities applied to each parent than if the couple is married. For example, a woman who gives birth to a child immediately has custody of that child. If an unmarried father wishes to claim legal paternity of the child, he must do so through one of several established ways.

Rights and Responsibilities of Unmarried Mothers

Mothers are automatically considered the primary custodian of a child they bear. This means that they have authority over decisions related to their child’s welfare as well as the responsibility to care for the child. More specifically, they have the right to make decisions about school, childcare, geographical moves, healthcare, religious affiliation, sports, summer camps, travel, and other aspects of the child’s life. It should be noted that there are some extreme cases in which a mother does not get custody of a child she gives birth to. For example, mothers who were found to have been using illegal drugs while pregnant can be disallowed immediate physical or legal custody of their child.


Naperville paternity lawyersWhen an opposite-sex married couple has a child, the father is legally presumed to be the husband of the mother. When an unmarried couple has a baby, there is no presumed father. In order to be the legal father of a child, an unmarried father must establish paternity. Legal paternity gives the father certain rights and responsibilities. For example, the legal father of a child has the right to enjoy visitation, or parenting time, with the child. He will also likely be expected to pay child support. There are several ways for an unmarried father to establish paternity in Illinois.

Voluntary Acknowledgement of Paternity

If both parents agree on the paternity of the child, the process for establishing paternity is quite simple. Parents may sign a voluntary acknowledgement of paternity and then file the form with the court. This simple paperwork can be done immediately after a child’s birth in the hospital. The voluntary acknowledgement of paternity can also be signed at any time after the child’s birth. After paternity is established in this way, a father’s name is added to the birth certificate. In some cases, a voluntary acknowledgement may not be necessary if both parents confirm the identity of the father.
