Paternity and Parenting Time in Illinois: Rights for Unmarried Parents

Unmarried parents in Illinois can have the same important rights and responsibilities as married parents, but the legal process may look different. Before a court can decide parenting time, decision-making responsibilities, or child support, parentage usually needs to be legally established.

Parentage is the legal parent-child relationship. Once parentage is established, both parents may have rights and duties involving the child, including support, parenting time, medical coverage, and the ability to ask the court for decision-making authority.

For unmarried parents, the biggest mistake is assuming that an informal agreement is enough. A handshake schedule, text-message arrangement, or verbal promise may work for a while, but it can become a problem when conflict starts, one parent relocates, child support becomes disputed, or one parent stops following the arrangement.

If you are an unmarried mother or father in Springfield, Sangamon County, or anywhere in Illinois, it is important to understand how paternity is established, what rights each parent may request, and what changes when paternity has already been established.

Why Paternity Matters for Unmarried Parents

Paternity, also called parentage, matters because it creates the legal parent-child relationship between the father and the child. Without legal parentage, an unmarried father may not automatically have enforceable parenting time or decision-making rights.

Establishing paternity can affect:

• Parenting time
• Decision-making responsibilities
• Child support
• Medical support
• Health insurance
• Birth certificate records
• Inheritance rights
• Access to school or medical information
• The ability to request court orders
• The ability to enforce parental rights

Illinois recognizes that every child has the right to physical, mental, emotional, and financial support from parents.

Mother’s Rights

Mother’s Rights are important in unmarried parent cases, especially when paternity has not yet been legally established.

An unmarried mother may have concerns about:

• Who can make decisions for the child
• Whether the father can demand visitation without a court order
• Whether child support can be ordered
• Whether the father’s name can be added to the birth certificate
• Whether the father can take the child without an agreement
• Whether a parenting schedule should be formalized
• Whether safety concerns affect parenting time

If paternity has not been established, the mother may need to address parentage before support, parenting time, or decision-making issues can be fully resolved.

Once parentage is established, the mother may ask the court to decide parenting time, decision-making responsibilities, and child support if the parents cannot agree.

Father’s Rights

Father’s Rights depend heavily on whether legal paternity has been established. Being the biological father is not always the same as being the legally recognized parent for court purposes.

Once paternity is established, a father may ask for:

• Parenting time
• Decision-making responsibilities
• Access to school and medical information
• A parenting schedule
• Holiday and vacation time
• Participation in major child-related decisions
• Modification of an existing parenting order
• Enforcement if the other parent refuses court-ordered time

Illinois Legal Aid explains that once parentage is established, a parent can seek parental responsibilities, including decision-making power and parenting time.

However, signing a Voluntary Acknowledgment of Parentage does not automatically give a father a parenting schedule. It establishes parentage, but a separate parenting time or parental responsibility order may still be needed.

Informal Deals

Informal Deals are common between unmarried parents. At first, both parents may agree on when the child visits, who pays for expenses, and how decisions will be made.

Informal arrangements may include:

• Text-message visitation schedules
• Verbal child support agreements
• Shared transportation plans
• Flexible weekend visits
• Unofficial holiday arrangements
• Agreements about school or medical decisions
• Shared expenses without a court order

The problem is enforceability. If one parent stops following the informal deal, the other parent may have limited options unless there is a court order.

Informal deals can also create confusion about:

• Missed visits
• Late pickups
• Unpaid expenses
• School enrollment
• Medical decisions
• Travel
• Relocation
• Child support
• Emergency decisions

A written court order gives both parents clearer expectations. It also gives the court something to enforce if one parent refuses to cooperate.

How to Establish Paternity

How to Establish Paternity depends on whether both parents agree and whether there is a dispute.

In Illinois, paternity may be established through:

• Voluntary Acknowledgment of Parentage
• Court order
• Genetic testing in disputed cases
• Presumptions under Illinois law in certain circumstances

For many unmarried parents, the two most common paths are signing a Voluntary Acknowledgment of Parentage or asking the court to enter a parentage order.

Voluntary Acknowledgment

Voluntary Acknowledgment refers to a Voluntary Acknowledgment of Parentage, often called a VAP. This is a legal document used to establish parentage when the parents agree.

Illinois law provides that a parent-child relationship may be established voluntarily by signing and witnessing a voluntary acknowledgment.

A valid VAP filed with the Illinois Department of Healthcare and Family Services is equivalent to an adjudication of parentage and gives the acknowledged parent the rights and duties of a parent.

A VAP may be useful when:

• Both parents agree who the father is
• There is no dispute about parentage
• The parents want the father legally recognized
• The parents want to create a basis for child support
• The parents want to move forward with parenting time or decision-making issues

But a VAP has limits. Illinois HFS explains that signing the acknowledgment includes financial support responsibilities, but does not give parental responsibility allocation or parenting time to the biological father by itself.

That means a father may still need to file in court to obtain a parenting schedule or decision-making rights.

Court Order

Court Order parentage may be needed when the parents do not agree, when genetic testing is requested, when one parent refuses to sign a VAP, or when parenting time, decision-making, and support issues need to be resolved formally.

A court may address:

• Legal parentage
• Genetic testing
• Birth certificate issues
• Parenting time
• Decision-making responsibilities
• Child support
• Medical support
• Insurance coverage
• Tax-related child issues
• Allocation of expenses
• Court costs and attorney fees in some cases

A court order is especially important when parents disagree about access, safety, support, or the child’s best interests.

Court orders are enforceable. That is the key difference. An informal arrangement may depend on cooperation, while a court order gives both parents clear legal rules. No guessing game. No “but you said last Tuesday” courtroom drama.

Parenting Time and Decisions

Parenting Time and Decisions are separate issues under Illinois law.

Illinois no longer uses the word “custody” in the same way many people use it casually. Instead, courts generally address:

• Parenting time
• Significant decision-making responsibilities

Parenting time means when the child spends time with each parent. Decision-making responsibilities involve major decisions for the child.

Illinois courts focus on the child’s best interests when deciding these issues.

Parenting Time

Parenting Time refers to the time a child spends with each parent. Once parentage is established, a parent who has not been granted significant decision-making responsibilities is still generally entitled to reasonable parenting time unless the court finds that parenting time would seriously endanger the child or significantly impair the child’s emotional development.

Parenting time orders may address:

• Weekday visits
• Weekend schedules
• Holidays
• School breaks
• Summer time
• Transportation
• Exchanges
• Pick-up and drop-off locations
• Phone or video contact
• Missed visits
• Make-up parenting time
• Safety restrictions if needed

If parents agree, they may submit a parenting plan. If they cannot agree, the court may decide based on the child’s best interests.

Decision-Making

Decision-Making refers to major decisions about the child’s life. Illinois courts may allocate significant decision-making responsibilities between the parents.

Major decision categories often include:

• Education
• Health care
• Religious upbringing
• Extracurricular activities

Illinois law says that unless parents agree in writing on allocation of significant decision-making responsibilities, the court makes the determination. Each parent generally has responsibility for routine decisions and emergency health and safety decisions during that parent’s parenting time.

Decision-making can be shared, divided by topic, or allocated primarily to one parent depending on the facts and the child’s best interests.

Child Support

Child Support is separate from parenting time and decision-making. A parent can be required to support a child even if parenting time is limited, disputed, or not yet ordered.

Child support may include:

• Monthly support
• Medical support
• Health insurance
• Uncovered medical expenses
• Child care expenses
• School expenses
• Extracurricular costs
• Past-due support in some cases

Parentage established through a valid acknowledgment can serve as a basis for seeking a child support order without further proceedings to establish parentage.

This means that once parentage is legally established, the court or child support agency may address financial support.

Income Shares

Income Shares is the child support model Illinois uses. Illinois HFS explains that Illinois replaced the old percentage-of-noncustodial-parent-income model with the Income Shares model effective July 1, 2017.

The Income Shares model considers both parents’ incomes and the amount parents in a household would typically spend on the child based on combined income and family size.

Child support calculations may consider:

• Each parent’s income
• Number of children
• Parenting time arrangement
• Health insurance
• Child care costs
• Other support obligations
• Shared parenting or split care situations
• Adjustments allowed by law

Income Shares does not mean both parents always pay the same amount. It means the calculation looks at both parents’ financial circumstances.

Separate Rules

Separate Rules apply because paternity, parenting time, decision-making, and child support are connected but not identical.

Important distinctions include:

• Establishing paternity does not automatically create a detailed parenting schedule
• A parenting time order does not automatically eliminate child support
• Child support can be addressed even if parenting time is still disputed
• Decision-making is separate from parenting time
• Informal agreements may not be enforceable without a court order
• A VAP can establish parentage, but parenting time may still require court action
• Existing orders may need modification if circumstances change

This is where many unmarried parents get confused. Paternity answers the question, “Who is the legal parent?” Parenting time answers, “When does the child spend time with each parent?” Decision-making answers, “Who makes major choices?” Child support answers, “How is the child financially supported?”

They are related, but they are not the same.

If Paternity Is Already Established

If paternity is already established, the next step is usually not proving parentage again. The next step is deciding what needs to be ordered, enforced, or modified.

If paternity already exists through a VAP or court order, a parent may need help with:

• Creating a parenting time schedule
• Enforcing parenting time
• Requesting decision-making responsibilities
• Setting child support
• Modifying child support
• Addressing unpaid support
• Changing a parenting schedule
• Handling relocation concerns
• Addressing safety concerns
• Updating an old order
• Resolving disputes over school, health care, or activities

This is an important distinction. If parentage is already legally established, the case may move directly into parental responsibilities, parenting time, or support issues.

Common Disputes Between Unmarried Parents

Unmarried parents may face disputes involving:

• Whether paternity has been legally established
• Whether the father is on the birth certificate
• Whether a VAP was properly signed
• Whether genetic testing is needed
• Whether informal parenting time should continue
• Whether one parent is withholding the child
• Whether child support should be ordered
• Whether the child should travel
• Whether one parent should have primary decision-making
• Whether safety restrictions are needed
• Whether the existing order should be modified

A court order can reduce ambiguity and create a clear framework for both parents.

What You Should Do Before Filing

Before filing a paternity or parenting time case, gather documents that may help.

Useful records may include:

• Birth certificate
• Voluntary Acknowledgment of Parentage
• Prior court orders
• Child support documents
• Text messages about schedules
• Payment records
• School records
• Medical records
• Proof of involvement with the child
• Work schedules
• Proposed parenting schedule
• Safety-related documentation if relevant

Do not rely only on memory. Courts like documentation. Memory is helpful, but screenshots are often more persuasive than “I promise this happened.”

A family law attorney in Springfield can help review your records, explain filing options, and prepare the documents needed for a paternity or parenting time case.

How a Springfield Family Law Attorney Can Help

A Springfield family law attorney can help unmarried parents understand their rights and next steps.

An attorney may help with:

• Establishing paternity
• Reviewing a VAP
• Filing a parentage case
• Requesting genetic testing
• Creating a parenting plan
• Seeking parenting time
• Requesting decision-making responsibilities
• Establishing child support
• Modifying existing orders

The right approach depends on whether paternity is disputed, already established, or connected to an existing child support or parenting order.

Final Thoughts

Paternity and parenting time in Illinois are especially important for unmarried parents. Establishing paternity creates the legal parent-child relationship, but it does not always create an automatic parenting schedule or decision-making order.

Mothers and fathers may both have rights once parentage is established. Informal deals can work temporarily, but court orders are usually stronger because they are enforceable.

If paternity is already established, the next step may be parenting time, decision-making, child support, enforcement, or modification. If you are dealing with these issues in Springfield or Sangamon County, speak with a family law attorney as soon as possible to protect your rights and your child’s best interests.
