How does the adoption process work in Illinois?

Federal & State Law Editorial TeamLast reviewed: 2026-05-17

Illinois's Adoption Act (750 ILCS 50/) is administered in the Circuit Court's juvenile or chancery division and uses a strong irrevocable-consent regime.

1. Types of Adoption

  • Agency adoption through a DCFS-licensed agency.
  • Private-placement adoption (50/4).
  • Related/step-parent adoption (50/1(B)).
  • Standby adoption (50/3.1).
  • Adult adoption (50/3).
  • 2. Petitioner Eligibility

    Under 750 ILCS 50/2, a reputable adult of either sex with at least 6 months Illinois residency (or 90 days for military) may petition. A spouse must join unless the spouse is the natural parent.

    3. Consent Requirements

    A Final and Irrevocable Consent to Adoption under 750 ILCS 50/9 cannot be signed earlier than 72 hours after the child's birth. Once executed before a judge or designated person, the consent is irrevocable except on proof of fraud or duress within 12 months (§ 11). A Surrender to an Agency under § 10 is similarly irrevocable on execution.

    4. Home Study

    Required for all non-related placements and conducted by a DCFS-licensed agency under § 6. Related adoptions (step-parent, grandparent, sibling) are exempt unless the court orders one. A post-placement supervision period precedes finalization.

    5. Termination of Parental Rights (TPR)

    Voluntary by consent/surrender. Involuntary on unfitness grounds enumerated in 750 ILCS 50/1(D) — including abandonment, depravity, habitual drunkenness, or failure to maintain reasonable interest. Interstate placements follow ICPC (45 ILCS 15/). ICWA (25 U.S.C. § 1901) applies to Native American children.

    6. Finalization Hearing

    The Circuit Court holds the hearing approximately 6 months after placement. The judge enters the Order of Adoption (§ 14), and the Illinois Department of Public Health issues a new birth certificate.
