Making the decision to grow your family through adoption is an exciting milestone. Now comes the part nobody looks forward to: the paperwork, the court dates, and the waiting.
This guide breaks down what the adoption process actually looks like in Illinois—who qualifies, the steps and timeline, how things differ depending on the type of adoption, and what it typically costs.
Who Can Adopt in Illinois?
Wondering if you meet the adoption qualifications in Illinois? The good news is our state keeps eligibility fairly broad. Single, married, young, older, gay, straight, first-time parent or not, most people clear the bar. To adopt, you’ll generally need to:
- Be a legal adult
- Pass a criminal background check
- Complete a home study, an in-depth review of the household where the child will live
Single adults can adopt, as can married couples. There’s no strict statewide age ceiling, but the court will consider whether a prospective parent’s age and health support raising a child long-term.
The Adoption Process and Timeline, Step by Step
Wondering what you need to do to finalize your adoption and how long it will take? The adoption process in Illinois generally breaks down into 6 steps. The timeline can vary quite a bit—from a few months to a few years—depending on the type of adoption and whether it’s consensual or contested.
1. Home Study
Before a child can be placed in your home, a licensed caseworker evaluates your household, background, and readiness to adopt. Related adoptions (stepparent, grandparent, sibling) are generally exempt from this requirement unless the court orders it.
Typical Timeline: 4-8 weeks
2. Matching, or Waiting for a Placement
Once your home study is approved, you’re eligible to be matched with a child—but the wait for an actual placement varies enormously, and it’s often the longest stretch of the whole process.
- Domestic infant matching can take anywhere from a few months to over a year, depending on the agency and birth parent availability.
- International adoptions may add extra paperwork and a referral wait from the home country.
- Foster-to-adopt works differently; most families end up adopting the same child they’re already fostering, so there’s often no separate “matching” process at all. The real variable is how long it takes that child to become legally free for adoption, which depends on a separate juvenile court process that can run anywhere from months to a couple of years.
Typical Timeline: Several weeks to over a year
3. Consent, or Termination of Parental Rights
The biological parent(s) must consent to the adoption, or their rights must already be legally terminated, before a child can be placed with you. For infant adoptions, a birth parent can’t sign consent until at least 72 hours after birth.
When consent isn’t given at all, the case shifts into contested territory and the timeline extends significantly.
Typical Timeline: Minimum 72 hours after birth; Up to several months if contested
4. The Child Moves In, and We File the Petition to Adopt
Once consent or termination is in place, the child is placed with you. The Petition to Adopt is typically filed around this same point, and the court enters an “interim” (temporary) custody order while the case proceeds.
Typical Timeline: A few days to a few weeks
5. Post-Placement Supervision Period
Illinois generally requires the child to live with you for at least 6 months before the adoption can be finalized, giving the court time to confirm the placement is working well. This period is typically waived for related adoptions.
Typical Timeline: Minimum 6 months, for non-related adoptions
6. Finalization Hearing
A judge reviews the case and, if everything checks out, issues a final adoption order. This makes the adoption legally permanent.
Typical Timeline: 2-6 weeks
These are general ranges, not guarantees. A relative or current foster parent may be able to move through these steps in a few months. On the other hand, a contested case, an international adoption, or a local court’s scheduling backlog can stretch things out considerably.
The most accurate way to get a sense of your timeline is to talk through the specifics of your case with an attorney.
How the Adoption Process Varies by Type
The type of adoption you’re pursuing can change which of the steps above apply, and how long each one takes.
- Related adoptions (stepparent, grandparent, or sibling) are usually the fastest path, skipping the home study and matching wait. These cases often take just a few months from petition to finalization.
- Domestic adoption is most often facilitated by an agency. The licensed agency conducts home visits and matches a child with prospective parents.
- Independent (aka private) adoption skips the agency entirely. Matching happens directly between biological and adoptive parents, often with an attorney playing a larger role in the process.
- International adoption follows the same general framework, but adds federal immigration requirements, and sometimes additional treaty compliance, on top of the standard steps.
- Infant and newborn adoption follows the general process closely, but the timing of parental consent is the key variable. Parents must wait at least 72 hours to sign consent. If the father is not present or contests the adoption, that can add extra steps to the process.
- Foster care adoption can move relatively quickly if you’re already a licensed foster parent and want to adopt a child in your care. However, becoming a licensed foster parent takes roughly 3-9 months and requires 30+ hours of online training. Before a child is cleared for adoption, the Illinois Department of Children & Family Services (DCFS) is legally required to make active, reasonable efforts to reunify the family—but they will typically terminate parental rights after 15 months.

What If a Biological Parent Doesn’t Consent?
Not every adoption proceeds with both biological parents’ agreement. When that happens, the Illinois adoption process gets more complicated.
- The Petition for Adoption has to state the legal basis. Instead of simply attaching a signed consent form, the petition must allege that the biological parent is “unfit” and identify the specific legal grounds for that claim, or that their consent isn’t required under the law.
- The parent gets notice and a chance to contest. They’re formally served and given the opportunity to appear and dispute the claim.
- If contested, it goes to a fitness hearing. The petitioner has to prove unfitness with “clear and convincing evidence”—a higher bar than the standard used in most civil cases.
- The grounds for unfitness are specific. Common ones include abandonment, failure to maintain reasonable interest or contact with the child, desertion for more than 3 months, repeated or substantial neglect, failure to protect the child from harm, and extreme or repeated cruelty.
- A fitness finding isn’t the end of it. Illinois requires a separate best-interests hearing before the court will actually terminate a parent’s rights.
- Once parental rights are terminated, they’re final. There’s no undoing it except through a direct appeal.
Before any of that plays out, the question often arises: Does the biological father have legal standing to consent in the first place? If paternity was never legally established—through marriage, a signed acknowledgment, a court order, or registration with the Illinois Putative Father Registry—the biological father’s consent may not be required at all.
Contested adoptions require a much more careful legal strategy than a standard, consensual adoption, and the timeline extends accordingly. If this applies to you, call our experienced adoption attorneys at (630) 852-1100 for a free consultation.
How Much Does Adoption Cost?
Adoption costs vary based on the type of case, but a few factors show up consistently: attorney’s fees, court filing fees, and home study fees. Agency-facilitated and international adoptions typically carry additional agency or administrative costs on top of these.
