750 ILCS 50/6 · Investigator appointed within 10 days of filing · State + FBI fingerprint checks · Reports no older than 2 years · Waived for related adoptions · About $4,500 in central Illinois

Every Illinois adoption of an unrelated child includes a court-ordered investigation, commonly called a home study (750 ILCS 50/6). A licensed agency or court-appointed investigator interviews the family, visits the home, checks references, and runs fingerprint background checks. Related and stepparent adoptions skip it unless the judge orders one.

The home study is the step that worries adoptive parents the most, and it is almost never as bad as they fear. It is a structured look at your household by a trained investigator who reports to the judge. This article explains who conducts it, what it covers, what it costs in central Illinois, when the law waives it, and what to do if something in your history needs explaining.

What is the home study in an Illinois adoption?

Illinois law calls it an investigation. Under 750 ILCS 50/6, part of the Illinois Adoption Act, the circuit court must order an investigation whenever the child being adopted is not related to the petitioners. The investigator studies the home, the petitioners, and the allegations in the petition, then files a written report with the court.

In practice, families encounter the process in two forms:

The pre-placement home study. A licensed child welfare agency evaluates your family before a child is placed with you. Agency adoptions, foster care adoptions, and interstate placements all require one up front.
The court-ordered investigation. After the adoption petition is filed, the court appoints an investigator within 10 days. When a licensed agency already completed a home study, the court appoints that agency and the earlier work does double duty.

Both versions answer the same question for the judge: are the petitioners proper persons to adopt, and is this child a proper subject for adoption? The report is advisory. The judge, not the investigator, makes the decision.

Who conducts the home study, and who picks them?

For an unrelated child, the court appoints one of the following within 10 days after the petition is filed:

a child welfare agency licensed and approved by DCFS,
a person the court considers competent to investigate, which in some counties is a probation officer or the guardian ad litem,
the court’s own social service staff in counties that have it, or
DCFS itself, when no agency is available or the petitioners cannot afford one.

In an agency adoption, the placing agency ordinarily serves as the investigator because it already completed the home study before placement. In a private adoption in the Tenth Judicial Circuit, which covers Peoria County, the judge selects the investigator at the interim order stage, the same order that appoints a guardian ad litem for the child. A guardian ad litem is the attorney appointed to represent the child’s interests in the case.

That last option matters for cost. If paying for a private agency study would be a hardship, tell your attorney. The statute directs DCFS to conduct the investigation when the petitioners cannot pay, and the court can order it.

What does the Illinois home study cover?

The scope comes straight from 750 ILCS 50/6: the truth of the petition’s allegations, and the petitioners’ character, reputation, health, and standing in the community, along with whether they are proper persons to adopt and the child is a proper subject. The statute even directs the investigator to note the religious faith of the petitioners and, where it can be determined, of the child.

Concretely, expect the investigator to look at:

Interviews. Every member of the household talks with the investigator, adults individually and children in an age-appropriate way.
The home visit. A walk-through of the residence for basic safety, space, and living conditions. Investigators are looking for a safe, stable home, not a model house.
Background checks. Fingerprint-based criminal checks and a child abuse and neglect registry check, covered in the next section.
Health. Statements from your physician about the petitioners’ health, plus disclosure of significant conditions.
Finances. Income verification, employment, and enough documentation to show the family can support the child. There is no wealth requirement.
References. Written or interviewed personal references who know your family.
Motivation and readiness. Why you want to adopt, how you will handle the child’s questions about adoption, and your parenting plan.

What background checks are required?

Two checks are built into every Illinois adoption investigation:

Fingerprint-based criminal history checks through both the Illinois State Police and the FBI. Name-only checks do not satisfy the statute.
A CANTS check, the DCFS Child Abuse and Neglect Tracking System, which shows whether anyone in the household has an indicated finding of abuse or neglect.

Two timing rules trip people up. First, the criminal background report the court relies on cannot be more than 2 years old, so a stale check from an earlier process gets redone. Second, checks reach beyond the petitioners: adult household members, including anyone over 17, should expect to be fingerprinted as well.

How long does a home study take in central Illinois?

Plan on weeks to several months, driven almost entirely by the agency’s schedule and how fast you assemble documents. The moving parts:

Agency intake and scheduling: the biggest variable. Some agencies start within days, others have waiting lists.
Fingerprint results: Illinois State Police and FBI results take weeks, not days. Start them first.
Your paperwork: tax returns, physician statements, and references come together in a week when you are organized, and a month when you are not.
Writing the report: after the final visit, the investigator needs time to write. Ask up front how long, and whether a rush option exists. Agencies add a fee for fast turnaround.

In our private adoption cases in Peoria County, the court-ordered investigation frequently finishes well before the six-month mark that governs when an unrelated adoption can be finalized, and we push to finalize as soon as the law allows. For the full timeline from petition to judgment, see our post on how long adoption takes in Illinois.

What does an Illinois home study cost?

Real numbers, current as of July 2026:

Private agency home study: around $4,500 in central Illinois. Statewide, fees run from $2,000 to $10,000 depending on the agency and how fast you need the report.
Foster care adoptions: families adopting a child from DCFS care get the home study free of charge, from DCFS or an agency under contract with DCFS. The trade-off is a slower process.
Reimbursement help: for adoptions of children in DCFS care, the DCFS Adoption Attorney Payment Program reimburses up to $2,250 per child in nonrecurring adoption expenses, which can include fees connected to completing the case.
Court-appointed alternatives: when the petitioners cannot afford an agency, the statute lets the court send the investigation to DCFS at no charge.

Ask any agency for its fee schedule in writing before you sign, including the home visit count, update fees, and rush charges. An update, when your study is older than a year or your household changes, costs a fraction of a new study.

When is the home study waived in Illinois?

Illinois waives the investigation in two big categories, both under 750 ILCS 50/6:

Related adoptions. When the child is related to the petitioner, the statutory investigation does not apply. The Adoption Act’s definition of a related child reaches to second cousins and includes stepparents, so grandparent, aunt and uncle, sibling, and stepparent adoptions all skip the home study. The court keeps discretion to order an investigation anyway, and when it does, sworn affidavits from the petitioners often satisfy it rather than a full agency study.
Adult adoptions. Adopting a person who is 18 or older requires no investigation unless the court orders one.

The waiver is one of the main reasons relative adoptions finish months faster than stranger adoptions. We covered that path in detail, including the two-to-three-month timeline for uncontested cases, in our post on adopting a relative in Illinois without a home study. Stepparent adoptions get the same treatment; the stepparent counts as related, so the case turns on consent or termination of the absent parent’s rights, not on an investigation of your home. Our stepparent adoption practice page covers those cases.

When Illinois requires an adoption investigation
Adoption type	Home study / investigation	Governing rule
Private or agency adoption of an unrelated child	Required; investigator appointed within 10 days of filing	750 ILCS 50/6
Related adoption (through second cousins)	Waived unless the court orders one	750 ILCS 50/6
Stepparent adoption	Waived unless the court orders one; stepparent counts as related	750 ILCS 50/6
Adult adoption (18+)	Waived unless the court orders one	750 ILCS 50/6
Child coming from another state	Illinois home study required before ICPC approval	45 ILCS 15
Child born abroad	Home study plus additional post-placement requirements	Federal and state intercountry rules

What about a child coming from another state?

Interstate placements add one wrinkle that catches families off guard. Any Illinois resident adopting an unrelated child from another state must clear the Interstate Compact on the Placement of Children (45 ILCS 15), and the ICPC packet requires a completed home study by a licensed Illinois child welfare agency, plus the fingerprint checks, before the child can cross the state line.

That sequencing is the trap: the home study has to exist before placement, not after. A family that waits for a match before starting the study can watch a placement fall through over paperwork. In our interstate cases, families should plan for roughly 10 to 14 days from the child’s birth to ICPC approval when the home study is already done, and far longer when it is not. Start the study the moment interstate adoption becomes a possibility. The full process is covered in our post on how the ICPC interstate adoption process works.

How should you prepare for the home study?

Preparation is mostly paperwork and candor. Before the first visit:

Gather certified copies of birth certificates, your marriage certificate, and any divorce judgments.
Pull your last filed tax return and recent pay stubs.
Schedule physicals so physician statements are ready.
Line up three to five references who know your household well, and warn them the call is coming.
Get fingerprints scheduled early, because state and FBI results are the slowest item.
Do the ordinary safety pass at home: working smoke detectors, medications and firearms secured, a bedroom plan for the child.

Then relax about the visit itself. The investigator has seen real houses with real laundry. What sinks a study is not clutter; it is concealment. Answer questions completely, volunteer the hard facts before the background check surfaces them, and let your attorney frame anything complicated in advance.

What happens if a problem surfaces during the investigation?

Issues fall into two very different buckets:

Explainable history. An old arrest, a bankruptcy, a health condition, a long-ago DCFS contact that was unfounded. These do not automatically end an adoption. The investigator’s job is a complete picture, and the judge weighs context: how long ago, what changed, and what the household looks like now. Disclose early, document the changes, and address it head-on in the report rather than hoping it stays buried.
Disqualifying findings. Certain serious criminal convictions and indicated findings of abuse or neglect will stop an agency from approving a home, and no attorney can paper over them. If you have any doubt about which bucket your history lands in, have that conversation with counsel before you spend money on a study.

If an agency declines to approve your home, get the reason in writing. Some problems are fixable, an updated study after a household change is routine, and a second opinion from a different licensed agency is sometimes warranted.

What happens after the report goes to the judge?

The investigator files the written report with the circuit court. From there:

In an uncontested case with a clean report, the case moves to finalization. For an unrelated child, judgment can be entered after six months from the interim order that placed the child with you, and the investigation is complete well before that in most files.
The guardian ad litem reviews the report and the file before the final hearing.
At finalization, the judge enters the judgment of adoption, and the clerk’s paperwork triggers the amended birth certificate naming you as the child’s parents.

The report itself stays in the confidential court file. Adoption files are sealed in Illinois, so the personal detail the study collects is not a public record. For the whole arc from first phone call to amended birth certificate, start with our guide to how to adopt a child in Illinois.

Frequently Asked Questions

How much does an adoption home study cost in Illinois?

Around $4,500 in central Illinois for a private agency study, with statewide fees running $2,000 to $10,000. Families adopting from DCFS foster care get the study free through DCFS or a contracted agency, and the court can route the investigation to DCFS when petitioners cannot afford an agency.

How long does the Illinois home study process take?

Weeks to several months. The agency’s schedule and the state and FBI fingerprint turnaround drive the timeline more than anything else, so start fingerprints and document gathering immediately. Rush processing exists at most agencies for an added fee.

Do stepparents need a home study in Illinois?

No. A stepparent counts as a related petitioner under the Adoption Act, so the 750 ILCS 50/6 investigation is waived unless the judge orders one. Stepparent cases turn on the other biological parent’s consent or the termination of that parent’s rights.

What background checks are part of an Illinois adoption home study?

Fingerprint-based criminal history checks through both the Illinois State Police and the FBI, plus a DCFS CANTS check for child abuse and neglect findings. The criminal background report must be less than 2 years old when the court relies on it, and adult household members are checked along with the petitioners.

Will a criminal record stop me from adopting in Illinois?

Not automatically. Old, minor, or isolated matters get weighed in context, and full early disclosure is the best strategy. Certain serious convictions and indicated abuse or neglect findings are treated as disqualifying by licensing standards. Review your history with an adoption attorney before paying for a study.

Who sees the home study report in an Illinois adoption?

The investigator files it with the circuit court, where the judge and the guardian ad litem review it. Illinois adoption files are sealed, so the report does not become a public record.

Can we use a home study from another state or an old study?

Illinois residents need an Illinois-compliant study by a licensed Illinois child welfare agency for interstate and unrelated adoptions, and the background check component cannot be older than 2 years. Most agencies update an existing study for a reduced fee when the original is theirs and your household has not changed.
