Important: This article is general information about Indiana adoption consent law. It is not legal advice, and whether an exception to consent applies is highly fact-specific. Contact an attorney about your situation.

It is one of the most common adoption questions, and one of the most emotional: a stepparent or relative has raised a child for years, the other biological parent has been absent or unwilling, and the family wants to make the relationship permanent. Can the adoption happen if that parent won't sign? In Indiana, sometimes it can — but only on specific legal grounds, and only after you prove them to the court.

Here is how Indiana handles adoption when a parent's consent is missing. For the broader process, see our adoption page and our guide to stepparent adoption.

The General Rule: Consent Is Required

Start from the default. Because adoption permanently ends a parent's legal rights, Indiana generally requires the consent of the child's existing legal parents (Ind. Code § 31-19-9). When a parent consents, the adoption is comparatively straightforward. The hard cases are the ones where a parent will not — or cannot — be brought to consent.

The Exceptions: When Consent Is Not Required

Indiana law spells out specific situations in which a parent's consent is not necessary (Ind. Code § 31-19-9). In general terms, these include where a parent has:

  • Abandoned or deserted the child for the period the statute requires before the petition is filed;
  • Failed, for at least a year, to communicate significantly with the child when able to do so;
  • Failed, for at least a year, to provide for the child's care and support when able and required to do so by law or judicial decree;
  • Had their parental rights terminated; or
  • Been found unfit, with the adoption shown to be in the child's best interests.

These are summaries, not the full statutory text, and each has nuances. The recurring themes are time (often a year), the parent's ability to act, and whether any failure was without justifiable cause.

What You Actually Have to Prove

An exception is not self-executing. The person seeking to adopt has to plead it and prove it to the court with real evidence — records of missed support, gaps in contact, attempts to involve the parent, and the like. "He was never really around" is a feeling; the court needs facts that fit the statute. The absent parent also has the right to appear and contest, and Indiana courts do not take ending a parent's rights lightly. Done carefully, though, these cases succeed every day for families where a parent truly has stepped away.

Notice, Missing Parents, and the Registry

Even when consent isn't required, notice usually still is. The court will expect diligent efforts to locate and notify the other parent, and a registered putative father is entitled to notice of the proceeding. Handling notice and the putative father registry correctly is what keeps an adoption final and not vulnerable to a later challenge. Skipping a step here is the most common way an adoption unravels.

The Hearing and the Outcome

If the court agrees an exception applies (or the parent consents or is properly defaulted) and the adoption is in the child's best interests, it grants the adoption at the final hearing. From that point the adoptive parent is, fully and permanently, the child's legal parent — and the relationship the family already lived is finally recognized by law.

Common Questions

Can I adopt a child without the other parent's consent in Indiana?
Sometimes. Consent is generally required, but IC 31-19-9 lists exceptions — for example, abandonment, a failure for a statutory period to communicate with or support the child when able, or a finding that the parent is unfit and the adoption is in the child's best interests. The petitioner must prove the exception to the court.
What counts as abandonment for an Indiana adoption?
In general terms, abandonment means a parent has left the child without meaningful contact or support, showing a settled intent to forgo parental responsibilities, for the period the statute requires. Courts look at the parent's actual conduct, not just labels. Whether the facts meet the legal standard is decided case by case.
Does not paying child support mean the other parent's consent isn't needed?
Not by itself. Indiana law can dispense with consent when a parent has failed, for at least a year and without justifiable cause, to provide support when able and required to do so — or has failed to communicate significantly with the child. Both the time period and the "without justifiable cause / when able" elements matter, and the court decides whether they are met.
What if I can't locate the other parent?
An adoption can still move forward, but the missing parent's notice rights and the putative father registry have to be handled correctly first. Courts require diligent efforts to locate and notify a parent, and a registered putative father is entitled to notice. Getting these steps right is essential so the adoption is not challenged later.

Other Parent Won't Consent?

Whether consent can be excused turns on the facts. Attorney Emilee Hammond can review your situation and tell you honestly whether the adoption can move forward.
