Adult adoption in Iowa is a court proceeding under Iowa Code Chapter 600 in which one adult becomes the legal parent of another adult. Because the person being adopted is grown, the process skips the home study, the 180-day residence period, and the termination of biological parental rights that a child adoption requires. Both parties file a petition, sign consents, appear briefly before a judge, and receive a decree that permanently rewrites their legal relationship for purposes of inheritance, records, and family status.
Who Can Adopt and Who Can Be Adopted
Iowa Code Section 600.4 allows three kinds of petitioners: an unmarried adult filing alone, a married couple filing together, or a married person filing separately in limited circumstances. A married person can petition alone only as the adoptee’s stepparent, or if the spouse has abandoned the marriage, is unavailable or incapacitated, or unreasonably refuses to join. Otherwise a married petitioner must file jointly with their spouse.1Iowa Legislature. Iowa Code 600.4 – Qualifications to File Adoption Petition
The adoptee needs only to be an adult. Iowa does not require the petitioner to be older than the adoptee, and it places no restriction on the underlying relationship. Stepparent adoptions, adoptions that formalize a long-standing parental bond, and adoptions between unrelated adults all use the same statute.
File the petition in the district court of the county where either the petitioner or the adoptee resides.2Iowa Legislature. Iowa Code 600.3 – Commencement of Adoption Action
Whose Consent Is Required
Biological parents do not consent, and their rights do not need to be terminated in advance. Section 600.3 makes that explicit when the adoptee is an adult.2Iowa Legislature. Iowa Code 600.3 – Commencement of Adoption Action
The adoptee’s own consent is required, in writing, under Section 600.7. It has to be signed either in front of the court or before a notary public.3Iowa Legislature. Iowa Code 600.7 – Consents to the Adoption
One consent requirement catches petitioners off guard. If a married person files separately to adopt an adult, the petitioner’s spouse must also consent under Section 600.7(1)(c), even though the spouse is not adopting anyone. If the spouse refuses or cannot be located, the petitioner attaches a verified statement explaining the situation, and the judge decides whether the case can move forward without that consent.3Iowa Legislature. Iowa Code 600.7 – Consents to the Adoption Any consent can be withdrawn before the decree is entered by filing an affidavit of consent withdrawal.
What the Petition Must Contain
Section 600.5 sets out the required contents of the petition, which the petitioner must sign and verify:
- The adoptee’s name as it appears on the birth certificate or after marriage, together with residence and the date and place of birth.
- The petitioner’s name, residence, and domicile.
- Any new name the adoptee wants the decree to establish.
- The names and addresses of the adoptee’s biological parents, even though their consent is not required.
- The provision of Section 600.4 that qualifies the petitioner to adopt.
- Disclosure of any conviction or deferred judgment beyond a simple misdemeanor and any founded child abuse report naming the petitioner.
Names and dates should match government identification exactly. Any prior name change or name-altering marriage should be disclosed, since mismatches with the birth certificate or other records slow the court’s review.
Filing, Fees, and the Hearing
Iowa requires electronic filing for court documents, including adoption petitions, through the Iowa Judicial Branch’s eFile system.5Iowa Judicial Branch. Electronic Filing The system is available to self-represented filers.
There is no filing fee. Iowa Code Section 602.8105 sets the fee for filing and docketing an adoption petition under Chapter 600 at zero dollars.6Iowa Legislature. Iowa Code 602.8105 – Fees for Civil Cases and Other Services The $195 civil filing fee listed on the Iowa courts website applies to other civil petitions, not to adoption.7Iowa Judicial Branch.

Two requirements that stretch out a child adoption do not apply here. Section 600.8 exempts adult adoptions from placement investigations and reports, so no home study is ordered.8Iowa Legislature. Iowa Code 600.8 – Placement Investigations and Reports Section 600.10’s 180-day minimum residence period applies only to minors.9Iowa Legislature. Iowa Code 600.10 – Minimum Residence of a Minor Child Once the petition and consents are filed, the case can move directly to hearing.
The hearing is conducted as an informal equity proceeding on the record. Only the parties, their witnesses, counsel, and anyone else the court requests may attend. Both petitioner and adoptee appear unless the court excuses one of them. The judge reviews the petition, confirms that both parties understand and want the adoption, and may ask about their relationship and intent.10Iowa Legislature. Iowa Code 600.12 – Adoption Hearing
What the Decree Changes
When the judge is satisfied that the statute has been met, the court enters a final adoption decree. The decree terminates the legal parental rights of the adoptee’s biological parents and establishes the adoptee as the legal child of the petitioner. Iowa treats that relationship as though it had existed from birth.11Iowa Legislature. Iowa Code 600.13 – Adoption Decrees
If the petition asked for a name change, the decree itself changes the name; no separate proceeding is needed. Within thirty days, the clerk sends a certified copy of the decree to the petitioner at no cost and forwards a copy to the Iowa Department of Health and Human Services.
HHS then establishes a new birth certificate under Iowa Code Section 144.23. The new certificate shows the adoptive parents’ names in place of the biological parents’ and reflects any name change ordered in the decree. The original certificate is sealed and generally cannot be inspected without a court order.12Iowa Legislature. Iowa Code 144.24 – Substituting New for Original Birth Certificates A certified copy of the new birth certificate costs $15 and can be used to update Social Security records, driver’s licenses, and other identification.13Health & Human Services.

Inheritance Effects Worth Thinking Through
The decree gives the adoptee full intestacy rights in the adoptive parent’s estate. If the adoptive parent dies without a will, the adopted adult inherits on the same footing as any biological child.11Iowa Legislature. Iowa Code 600.13 – Adoption Decrees
The other side of that same rule is easy to miss. Because the decree severs the legal parent-child relationship with biological parents, the adoptee generally loses the right to inherit from biological parents under intestacy law. Biological parents can still leave property to the adoptee by will, but there is no automatic claim if they die without one. Anyone expecting to inherit from a biological parent should talk to an estate planning attorney before filing.
Stepparent adoptions work differently on this point. When the petitioner is the adoptee’s stepparent, the decree does not terminate the parental rights of the petitioner’s spouse. The adoptee keeps one biological parent relationship intact and gains the stepparent as a legal parent.
What Adult Adoption Does Not Do
Three benefits that people sometimes expect from adult adoption are not actually available.
Immigration Status
Adopting an adult does not create a green card or citizenship path. Federal immigration law defines an adopted child as someone adopted before age sixteen, with a narrow sibling exception up to age eighteen. A U.S. citizen can petition for an adult adopted son or daughter only if the adoptee already met that definition when the adoption occurred as a minor. An adoption that first happens in adulthood does not qualify.14USCIS. Chapter 2 – Eligibility
Federal Adoption Tax Credit
The federal adoption tax credit is limited to a “qualified child,” defined as someone under eighteen or someone who is physically or mentally incapable of self-care. Adopting a healthy adult produces no credit.15Internal Revenue Service. Adoption Credit
Social Security Survivor Benefits
An adopted adult generally cannot claim Social Security survivor benefits on the adoptive parent’s record. Child survivor benefits go to unmarried individuals seventeen or younger, those eighteen to nineteen still in school full time, or adult children whose disability began before age twenty-two. Adult adoption alone does not create eligibility.16Social Security Administration. Who Can Get Survivor Benefits
Cost of Hiring an Attorney
With no filing fee, the main out-of-pocket cost is legal help. Uncontested adult adoptions are among the simpler matters a family law attorney handles, and many charge a flat fee. Rates vary by region and attorney, but a straightforward case with no consent complications commonly runs from a few hundred to a couple thousand dollars. Some petitioners file on their own, especially when both parties agree and there are no complicating factors such as a reluctant spouse or gaps in the adoptee’s records.
