In This TopicIdaho AdoptionTopic 3 of 6: Procedure and Decree

After an adoption petition is filed in Idaho, the case moves through notice, a hearing, and an order of adoption, sometimes called the decree. The Idaho Code sets deadlines for notice and objections, says who must appear at the hearing, and explains what the decree does (Idaho Code §§ 16-1505 through 16-1512).

This page is for adoptive parents preparing for the final hearing, and for anyone who has been served with notice of an adoption. Who may file and what the petition must say are covered in Who Can Adopt in Idaho.

Who Must Receive Notice

Notice of an adoption proceeding must be served on each of the following (Idaho Code § 16-1505(1)):

• Any person or agency whose consent or relinquishment is required under section 16-1504, unless that right has ended by waiver, relinquishment, consent, or judicial action, or the person’s parental rights were previously terminated (§ 16-1505(1)(a));
• Any person who has registered notice of the start of paternity proceedings under section 16-1513 (§ 16-1505(1)(b));
• The petitioner’s spouse, if any, only if the spouse has not joined in the petition (§ 16-1505(1)(c));
• Any person recorded on the birth certificate as the child’s father with the mother’s knowledge and consent, unless that right or his parental rights were previously terminated (§ 16-1505(1)(d));
• Any person openly living in the same household with the child when the mother signs her consent or makes a relinquishment, and holding himself out as the child’s father, unless those rights were previously terminated (§ 16-1505(1)(e)); and
• Any person married to the child’s mother when she signs her consent or relinquishes the child for adoption (§ 16-1505(1)(f)).

Except for people whose consent is required, the sole purpose of notice is to let the person served present evidence to the court about the child’s best interest (Idaho Code § 16-1505(9)). Whose consent is required is explained in Consent to Adoption in Idaho.

Timing and Content of Notice

Notice may be served right after the adoption case starts, but it must be served at least 21 days before the final dispositional hearing (Idaho Code § 16-1505(4)). The notice must specifically state that the person served must respond to the petition within 21 days of service if he intends to intervene in or contest the adoption (§ 16-1505(4)).

The notice does not need to disclose the name of the child’s mother (Idaho Code § 16-1505(3)). Neither the notice nor any other process in the case is required to contain the name of the person or persons seeking to adopt (§ 16-1505(8)).

How Notice Is Served

Person to be served	Method under the Idaho Code
A person whose consent is necessary under § 16-1504	Personal service. If reasonable efforts fail, the court shall order service by registered or certified mail to the last known address and publication once a week for three successive weeks in a newspaper the court designates (§ 16-1505(6)(a))
A person who registered notice of paternity proceedings under § 16-1513	Certified mail, return receipt requested, to the last address filed with the department (§ 16-1505(6)(c))
Any other person entitled to notice	Certified mail, return receipt requested, is sufficient; if it cannot be completed after two attempts, the court may order service by publication, posting, or any other manner (§ 16-1505(6)(b))

For a person whose consent is necessary, the hearing may take place no sooner than 21 days after service, or, if service is by mail and publication, no sooner than 21 days after the last publication (§ 16-1505(6)(a)). If service is by publication, the court designates what the notice says about the parties’ identities, and the notice may not include the name of the person or persons seeking to adopt (§ 16-1505(6)(a)).

Proof of service on everyone entitled to notice must be filed with the court before the final dispositional hearing (Idaho Code § 16-1505(7)).

Waiving Notice

Notice and appearance may be waived in writing before the court, or in the presence of and witnessed by a clerk of court or a representative of an authorized agency, provided the parent has been told the meaning and consequences of the adoption proceeding (Idaho Code § 16-1505(6)(a)). If the person lives outside Idaho, the waiver must be acknowledged before a notary and contain the person’s current address (§ 16-1505(6)(a)). A person who signs a waiver is not required to appear (§ 16-1505(6)(a)).

Objecting to an Adoption

A person served with notice who wants to contest the adoption must file a written objection in the adoption case within 21 days after service (Idaho Code § 16-1505(5)(a)). The objection must state the specific relief sought and be accompanied by a memorandum specifying its factual and legal grounds (§ 16-1505(5)(a)).

A person who does not file a written objection within 21 days after service waives any right to further notice, forfeits all rights in relation to the adoptee, and is barred from later bringing any action to assert an interest in the adoptee (§ 16-1505(5)(b)).

Combining Adoption With Termination

A proceeding to terminate the parent-child relationship under Chapter 20 and an adoption proceeding may be consolidated and decided at one hearing, as long as all requirements of both chapters are fully met (Idaho Code § 16-1506(5)). Neither chapter limits filing a petition, before the child’s birth, for approval of a verified financial plan for adoption expenses under section 18-1511 (§ 16-1506(5)).

In all disputed matters under Chapter 15 or Chapter 20, the paramount criterion for the court is the best interests of the child (§ 16-1506(5)). See Termination of Parental Rights in Idaho.

The Adoption Hearing

At the time set for the hearing, the person adopting, the child, and the petitioner’s spouse if that spouse is a natural parent of the child, must appear before the court of the county where the petition was filed (Idaho Code § 16-1506(1)). The petitioner must then sign an agreement that the child will be adopted and treated in all respects as the petitioner’s own lawful child (§ 16-1506(1)).

If an adoptive parent, or an adult being adopted, is a member of the armed services and cannot attend, that person’s appearance and testimony are received by deposition filed at the time of the hearing (Idaho Code § 16-1506(3)).

Before the adoption is finalized, the code also requires the following:

• Proof of service on everyone entitled to notice, filed before the final dispositional hearing (Idaho Code § 16-1505(7));
• For a child born out of wedlock with no showing that the unmarried biological father consented or waived his rights, a certificate from the state registrar of vital statistics about the search of the putative father registry, filed before the final decree (Idaho Code § 16-1504(5)); and
• Where the department or an agency investigated, the medical and genetic information compiled must be made available to the adopting family before the final order (Idaho Code § 16-1506(4)).

The Order of Adoption

The judge must examine all persons appearing, each separately, and any investigation report (Idaho Code § 16-1507). If satisfied that the child’s interests will be promoted by the adoption, the judge must make an order declaring that the child shall from then on be regarded and treated in all respects as the child of the person adopting (§ 16-1507). In the adoption of any foreign-born person, the judge must also make a finding of the true or probable date and place of birth (§ 16-1507).

For an adult adoption, the court shall enter an order granting the adoption once it finds that all required consents were given and the requirements of section 16-1501 have been proven to its satisfaction (Idaho Code § 16-1506(6)).

Foreign-Born Children

For a foreign-born child who entered the United States to be adopted, the petitioners and the child must appear at the hearing (Idaho Code § 16-1514(2)). If the judge is satisfied after examining the petitioners that the adoption is in the child’s best interests, the judge shall enter a decree of adoption, and the petitioners sign an agreement to treat the child as their own lawful child (§ 16-1514(2)). Chapter 20 does not apply to these adoptions (§ 16-1514(3)).

When an Idaho resident has adopted a child in a foreign country under that country’s laws, and the United States government recognizes the adoption as full and final, the resident may file a petition with the foreign decree, a certified English translation if needed, and proof of full and final adoption from the U.S. government (Idaho Code § 16-1514A(1)). The court then enters an order recognizing the foreign adoption without a hearing, with the same effect as an Idaho adoption order (§ 16-1514A(2)). The adoptive parents may then request a report of adoption under section 39-259 (§ 16-1514A(3)).

What the Adoption Does

A child or adult who is adopted may take the name of the person adopting (Idaho Code § 16-1508). From then on, the two have the legal relation of parent and child, with all of its rights and duties, including the right to inherit from any person to the same extent as a child of the whole blood under section 15-2-103 (§ 16-1508).

Unless the decree provides otherwise, from the time of the adoption the natural parents are relieved of all parental duties and responsibilities for the adopted child and have no rights over the child (Idaho Code § 16-1509). All rights of the child from and through the natural parents, including inheritance, end unless specifically provided by will (§ 16-1509).

Sealed Records

On the petitioners’ motion, or on its own motion, the court shall order that the record of the adoption proceeding be sealed (Idaho Code § 16-1511). Once sealed, the seal may be broken only on the motion of the petitioners or the adopted person, and the record may be sealed again (§ 16-1511).

Appeals and Finality

An appeal from an order granting or refusing an adoption goes to the Idaho Supreme Court (Idaho Code § 16-1512(1)). After the order of adoption becomes final, no party, and no one claiming under a party, may later question the adoption for any defect or irregularity, jurisdictional or otherwise, except by that appeal (§ 16-1512(2)).

For any reason other than fraud by the party adopting the child, no court may overturn an adoption, and no person or entity may collaterally attack it, more than six months after the order becomes final (§ 16-1512(2)). The statute says this provision is intended as a “statute of repose,” a fixed time limit (§ 16-1512(2)).

Dissolving an Adoption by a Former Stepparent

An adoption may be dissolved on petition, with the agreement of both the adoptee and the adopting parent, when the adopting parent was the spouse of a natural parent and that marriage has ended (Idaho Code § 16-1509A). The action may be started any time after the adoptee reaches 21 years of age (§ 16-1509A).

The court must determine that avoiding statutory care is not the purpose of the dissolution, unless it finds grounds to waive this finding (§ 16-1509A). If the petition comes after the adoptive parent’s death, the court shall specify the effect on inheritance rights (§ 16-1509A). See Stepparent and Relative Adoptions in Idaho.

How I Can Help

I help adoptive families serve notice correctly, track the 21-day objection period, gather the certificates and reports the court needs, and prepare for the final hearing. I also help people who have been served with notice understand the deadline to respond and what a written objection must contain. Request a consultation to discuss your situation.
