Adoption Consent Requirements in Illinois: When Is Parental Consent Not Required?

Illinois law presumes parental consent is required for adoption. But unfitness findings override that presumption. Here’s how the framework works.

The Rule: Consent Is Required—Unless

Section 8 of the Illinois Adoption Act, 750 ILCS 50/8(b)(1), specifies whose consent must be obtained before a child may be adopted. The mother, the father (meeting certain criteria), and sometimes others must execute consent documents. Adoption without consent is not possible—unless the court finds that consent requirement inapplicable.

The primary exception is straightforward: 750 ILCS 50/8(a)(1) provides that consent is not required when a parent is found unfit.

But “found unfit” requires proof. It is not a shorthand for “we think the child would be better off elsewhere.” Unfitness is a legal determination based on statutory grounds and clear and convincing evidence.

A recent case, In re Adoption of D.J.E., 2026 IL App (4th) 251115-U, illustrates how this framework operates when consent is disputed and grounds for TPR are contested.

Who Must Consent: The Statutory Criteria

Section 8(b)(1) requires consent from:

• The mother;
• The biological father, if he satisfies the statutory definition (or if he is the presumed father under the Uniform Parentage Act, 750 ILCS 46);
• Any person with a court order granting parental rights or guardianship.

For the biological father, the law distinguishes between different categories. The most straightforward is the “presumed father”—a man married to the mother at the time of conception or birth, or a man who has held himself out as the father and the mother has not objected. 750 ILCS 46/101 et seq.

If a man is not a presumed father, he may still assert parental rights through the Putative Father Registry. Under 750 ILCS 50/12.1, a putative father must register within 30 days of learning of the pregnancy or the child’s birth (or by a statutory deadline if notice of adoption is given). Failure to register constitutes a waiver of parental rights and consent requirements.

In D.J.E., both parents were identified and served. They were not putative-father registry issues. The fathers were presumed or identified, and they received notice of the adoption petition. The question was whether they could be found unfit.

The Statutory Grounds for Unfitness

Illinois law identifies specific grounds for finding a parent unfit. The petition in D.J.E. alleged two:

750 ILCS 50/1(D)(b): The parent is incapable of caring for the child due to mental or physical condition.

750 ILCS 50/1(D)(n): The parent has abandoned the child.

Other grounds exist, including the parent’s pattern of conduct that demonstrates indifference to the child’s welfare, the parent’s substantial and repeated refusal to follow court orders, and the parent’s sexual abuse or severe physical abuse of the child.

The statute does not require proof of all grounds. A finding on any single ground is sufficient to support TPR and to render consent unnecessary. In re C.W., 199 Ill. 2d 198, 217 (2002) (opinion ¶88). See also Donald A.G., 221 Ill. 2d 234 (multiple grounds can be alleged, but proof of one is sufficient).

In D.J.E., the Fourth District found that the second ground—abandonment under 750 ILCS 50/1(D)(n)—was clearly proved by clear and convincing evidence (¶122). This finding alone was sufficient to render consent unnecessary.

The Standard of Proof: Clear and Convincing Evidence

Unfitness must be proved by clear and convincing evidence. N.G., 2018 IL 121939, ¶28. This is a high bar—higher than “preponderance of the evidence” (which governs the best-interest determination) but lower than “beyond a reasonable doubt” (which governs criminal prosecution).

Clear and convincing evidence produces in the mind of the trier of fact a firm belief as to the truth of the allegations. It is not tentative or speculative. The factfinder must be substantially certain.

In D.J.E., the parents had not had contact with the child for years. The mother’s last contact was September 2022. The father’s last contact was end of 2021/early 2022. The child had been continuously in the guardians’ care since October 2018. No support had been paid. No attempt to reinitiate contact had been made.

That evidence—years of abandonment—clearly and convincingly proved the statutory ground. The trial court’s initial denial of the petition was error. The appellate court, reviewing the facts for manifest weight and the law de novo, found the ground was clearly proved.

Multiple Grounds: No Need to Prove Them All

Petitioners often allege multiple grounds for unfitness. In D.J.E., the petition alleged both incapacity (subsection b) and abandonment (subsection n). The trial court made an error in its analysis by conflating the two grounds rather than analyzing each separately (¶104).

This highlights an important point: while multiple grounds may be alleged, the court must analyze each ground distinctly and separately, applying the correct legal standard to each. A finding on one ground is sufficient, but the court cannot simply lump the grounds together and hope one of them sticks.

On appeal, the Fourth District applied the correct framework. It analyzed the statutory ground of abandonment, found it clearly proved, and held that this finding alone was sufficient (¶122).

Consent: How It Works and What It Means

When a parent consents to adoption, they execute a written consent document. Under 750 ILCS 50/9B, a written consent executed more than 72 hours after the child’s birth is final and irrevocable. The parent cannot revoke it. This is true even if the parent’s circumstances change or they have second thoughts.

For an infant adoption or private agency adoption, consent forms are obtained before TPR is ordered. For a child in state care (DCFS custody), consent may be obtained early, or the state may proceed directly to a petition for involuntary termination if the parents do not consent.

If one or both parents refuse consent, the petitioner must prove unfitness by clear and convincing evidence. The court will then find consent unnecessary and order TPR. At that point (or after), if both parents are found unfit, an adoptive parent, guardian, DCFS, or a court-appointed person may consent on behalf of the child.

In D.J.E., the biological parents did not consent. The guardians filed for adoption involuntarily. The trial court denied the petition (incorrectly). The appellate court reversed and remanded for a best-interest hearing. Once the trial court conducts that hearing and determines TPR is in the child’s best interest, the adoptive parents (the guardians) will be authorized to complete the adoption without parental consent.

The Putative Father Registry Exception

It is worth emphasizing the Putative Father Registry exception because it is a common issue.

If a man is not a presumed father under the Uniform Parentage Act, he may protect his parental rights by registering with the Illinois Putative Father Registry within 30 days of learning of the pregnancy or the child’s birth—or by the deadline set in a notice of adoption.

Failure to register constitutes a waiver. The man loses the right to withhold consent, and adoption may proceed without his consent. 750 ILCS 50/12.1.

This provision is important because it prevents men from lying in the weeds, years later objecting to an adoption they could have addressed earlier. It imposes a duty to act promptly.

In D.J.E., the biological father was identified and served with notice. There was no Putative Father Registry issue. The father received actual notice and could have objected or consented. He did neither. The issue was whether he was unfit, not whether he failed to register.

Consent vs. Unfitness: Two Different Paths

In our practice, roughly one in five adoption matters involves a contested proceeding — meaning at least one parent refuses consent or actively opposes the petition. The rest proceed by consent or default. This split shapes how we approach each case from the outset, because the two paths require very different preparation. Adoption can be completed through two routes:

Consensual adoption: Both parents (if rights are not suspended) consent. The adoption is streamlined. No hearing on parental fitness is necessary. The court simply approves the adoption based on the executed consents.

Involuntary termination: One or both parents refuse consent or cannot be located. The petitioner files a petition alleging grounds for unfitness. The court holds a hearing, hears evidence, and makes findings. If unfitness is proved by clear and convincing evidence, the court orders TPR. Consent becomes unnecessary.

In contested adoptions—those in which the parent objects—the involuntary termination route is required. The court must prove unfitness. Mere disagreement with the adoptive placement is not enough.

What “Unfit” Is Not

It is crucial to understand what unfitness is not. A parent is not unfit merely because:

• The child has been raised by others and bonded to them;
• The parent is not wealthy or well-educated;
• The parent made mistakes in parenting;
• The parent is not as good a parent as someone else might be;
• The court thinks the child would be better off adopted.

Unfitness is a legal status based on statutory grounds: abandonment, incapacity, abuse, pattern of indifference, or other specific conduct. It must be proved by clear and convincing evidence. It is not a subjective judgment.

This distinction explains why the trial court’s initial denial of the petition in D.J.E. was wrong. The trial court allowed best-interest thinking (the child has been so well cared for and bonded) to bleed into the unfitness analysis. But unfitness is not about best interest. It is about statutory grounds.

Frequently Asked Questions

Can a parent refuse to consent to adoption?

Yes. A parent can refuse consent. However, refusal does not prevent adoption if the parent is found unfit by clear and convincing evidence on a statutory ground. The adoption proceeds involuntarily. Consent is not required.

What is statutory abandonment?

Under 750 ILCS 50/1(D)(n), a parent has abandoned the child if the parent has failed to maintain a parental relationship with the child, failed to pay a reasonable share of the costs of care, and manifested an intent to forgo parental rights. Years of non-contact, lack of support, and inaction can constitute abandonment, as demonstrated in D.J.E..

If I miss the Putative Father Registry deadline, do I lose my parental rights?

Yes. The Registry is strict. If you are not a presumed father and you fail to register within the statutory deadline (typically 30 days of learning of pregnancy or birth, or by a deadline in a notice of adoption), you lose the right to withhold consent. The adoption can proceed without your consent. This rule is designed to prevent indefinite claims and to provide closure for adoptive families.

Can a parent who consents later change their mind?

Not if the consent was signed more than 72 hours after the child’s birth. Under 750 ILCS 50/9B, such consent is final and irrevocable. The parent cannot revoke it for any reason. This protects adoptive families and provides closure.

Who can consent on behalf of the child after both parents are found unfit?

Once both parents are found unfit, the court may appoint a guardian ad litem, DCFS, the petitioning guardians, or another suitable person to consent on the child’s behalf. This ensures the adoption can proceed and the child can achieve permanency.
