Idaho adoption law is found in Idaho Code Title 16, Chapter 15, and stepparent adoptions are filed in the Magistrate Court in your county. Here are the main points that matter to a stepparent family.
Where you file: Idaho has 44 counties, and each has a Magistrate Court. The clerk in your county can confirm local filing details.
Residency: Idaho sets a 6-month residency requirement under Idaho Code § 16-1506(1).
Child's consent: A child who is 12 or older must consent to the adoption under Idaho Code § 16-1504.
Other consents and paperwork: A typical Idaho filing includes:
- A Petition for Adoption
- Consent forms, or a termination petition
- The spouse's consent to the adoption
- The court filing fee
Idaho allows a parent's consent to be signed any time after the child's birth.
The other biological parent: Ending that parent's rights is handled through a separate termination petition in Idaho. Idaho Code § 16-2005 sets a 12-month abandonment period. Whether it applies to your family depends on your facts. If the other parent is unknown, cannot be found, or may object, the Magistrate Court clerk or an attorney can tell you how your situation would be treated. Where a parent's location is unknown, Idaho allows service by publication. Otherwise, papers can be served by a sheriff or process server.
Home study: A home study is typically waived for stepparent adoptions under Idaho Code § 16-1506.
Timeline: A stepparent adoption of a minor child generally takes about 3-6 months. An adult adoption generally takes about 4-8 weeks.
Cost: Court filing fees in Idaho typically run $150-$250. Families who prepare their own paperwork often spend under $1,000 in total. Hiring an attorney commonly costs $3,000-$5,000+.
Records: The Idaho Bureau of Vital Records and Health Statistics is the state agency that handles vital records, such as birth certificates.
What the law leaves to your facts: Adoption cases vary. If the other parent is contesting, cannot be located, or you are unsure how a rule applies to you, talk with the Magistrate Court clerk in your county or an attorney about that specific issue.
