A Complete Guide to Adoption in Illinois (2026)

If you’re interested in adopting in the Prairie State, you’ve come to the right place.

Adopting in Illinois is fairly straightforward, as most people who are 18 years old, have lived in the state for at least six months, and can provide a safe, stable home for children are eligible to adopt. There are no restrictions on marital status or sexual orientation.

This page offers a comprehensive guide to adoption in Illinois. We cover Illinois adoption laws and provide a step-by-step guide on how to adopt in the state. We also discuss home studies and provide a list of licensed adoption agencies in Chicago and beyond to get you started.

Illinois Adoption Laws at a Glance

Here’s a quick look at Illinois adoption laws.

Who Can Adopt?	Anyone who is at least 18 years old and does not have a legal disability (except for blindness) can adopt in Illinois.
Residency Requirements	Hopeful adoptive parents must have lived in Illinois for at least six months (or at least 90 days if they are in the military).
Marital Status	Single and married people can adopt in Illinois. Unmarried couples who want to adopt together must demonstrate that their partnership is stable and long-term.
Birth Mother Consent	Birth mothers in Illinois must wait at least 72 hours after their child’s birth before they can agree to an adoption.
Revocation Period	Once you give your consent to an adoption in Illinois, you can’t take it back unless you can prove you gave it under “fraud” or “duress.”
Birth Father Rights	Unmarried birth fathers in Illinois should register with the state’s Putative Father Registry within 30 days of your child’s birth. This allows you to receive legal notice of any adoption.

Adoption laws are complex. This is a summary for informational purposes only. Please consult with a qualified Illinois adoption attorney for legal advice.

Paths to Adopting a Child in Illinois

There are three main paths to adoption in Illinois:

Private Infant Adoption

Private infant adoption involves a match between two groups: the birth family and the adoptive family. In general, you can pursue private infant adoption either through a licensed child-placing agency or with the help of an adoption attorney.

An agency seeks out the best option for each member of the adoption “triad”—the birth family, the adoptive family, and the adoptee. Often, the agency will provide you with information about the child, allowing you to evaluate and accept or decline the match. The agency and birth mother often choose adoptive families based on profiles they create.

If you adopt through an attorney, you often have to find a child match yourself.

Adopting from Foster Care

Children end up in the Illinois foster care system when the State determines it’s not in their best interest to be with their birth families for the time being. Instead, they stay with licensed foster parents, who look after them during a difficult, transitional period in their lives.

Foster care is supposed to be temporary, and the State always hopes to reunite children with their birth families. However, in some cases, reunification isn’t possible or isn’t in the child’s best interest. In those cases, foster children often become eligible for adoption.

Adopting from foster care is often less expensive than private infant adoption. Foster children who are eligible to adopt are often older kids and may have siblings with whom they want to stick together.

Stepparent or Relative Adoption

Unlike other adoptive families, stepparents and relatives of the adoptee do not have to meet the Illinois residency requirements—meaning they don’t have to have lived in the state for six months.

Stepparent adoptions are when you legally want to adopt your partner’s biological child. The process is generally more straightforward because the birth parent doesn’t have to complete a background check. You also don’t have to complete a home study.

However, you do have to make sure the parental rights of the other parent are terminated, either voluntarily or through a court. A judge has to approve the adoption, and your stepchild also has to legally consent to it if they are at least 14 years old.

A Deeper Look at Illinois Adoption Laws

Here’s a more detailed look at Illinois adoption laws:

Who is Eligible to Adopt in Illinois?

The following conditions apply to people who can adopt in Illinois:

Must be at least 18 years old
Cannot have a legal disability (except for blindness)
Must have lived in Illinois for at least six months, unless they’re in the military (who must have lived in the state for 90 days)
Must have a “good reputation”

The six months requirement doesn’t apply in stepparent or relative adoptions.

Birth Parent Consent in Illinois

By Illinois law, a birth mother has to wait at least three days after her child’s birth before she can legally agree to an adoption.

Once she gives this consent, it’s hard to take it back. She can only revoke consent if she can prove it was given under “fraud or duress.” Also, she can only try to revoke consent within the first year after giving it.

Birth fathers can also revoke their consent to an adoption within the first 72 hours after their child’s birth. Unmarried birth fathers should register with the Putative Father Registry within 30 days of their child’s birth to make sure they get notified of adoption proceedings.

The Home Study Process in Illinois

All hopeful adoptive parents in Illinois have to complete a home study to show that their house and family are safe, welcoming, and ready for a child.

In Illinois, a home study includes the following aspects:

Fingerprint-based state and federal background checks
Child abuse and neglect registry checks
Pre-service training
An evaluation of the hopeful adoptive parents’ “character, reputation, health, and general standing in the community,” as well as their religious faith

After you welcome an adopted child, there will also be a postplacement study, to make sure that the child is adapting well to your home and family.

Adopting from Foster Care in Illinois

According to the Illinois Department of Children and Family Services (DCFS)—the state’s official public agency in charge of foster care and adoption—as of the end of 2025, there were more than 16,000 kids in the Illinois foster care system.

DCFS relies on foster parents to temporarily look after Illinois youth when their birth parents cannot provide a safe, stable home. While the State always hopes to reunite these children with their birth families, that is not always possible. In those cases, birth parents have their parental rights terminated, and foster children become eligible for adoption.

One path to adoption in Illinois is becoming a foster parent, then eventually adopting that foster child if they are eligible.

For the state’s foster-to-adopt pathway, foster children must have lived with the hopeful adoptive family for at least one year. The guardian (which may be the state) will give first preference and consideration to the foster parents, although the final decision will be based on the child’s best interest.

When making the decision, the guardian will consider several factors, including the following:

The child’s wishes
The wishes of the child’s birth parents
The depth of the relationship between the child and adoptive family
The mental and physical health of everyone involved

Resources for Expectant Parents in Illinois

Choosing to place your child for adoption is one of the most complicated, difficult decisions you can make. Know that you are not alone throughout the process, and no matter what action you decide to take, no one can force you to make a decision you aren’t comfortable with.

The Adoption Center of Illinois, based in Chicago, provides therapy and support groups for birth mothers. Lutheran Child and Family Services of Illinois, located just west of Chicago in Oakbrook Terrace, also offers several programs for expectant parents.

If you need support, just remember that you are never alone. You can speak to a trained counselor to talk through your options, make an adoption plan, and make the best decision for you and your child.

Reasonable and actual medical and hospital fees
