Can I adopt my stepchild who is a newborn or infant in Montana?

Yes, you can start a stepparent adoption of a newborn or infant in Montana through the District Court, and Montana sets no minimum residency period before you file (Mont. Code Ann. § 42-1-104(1)). For a baby, the main questions are usually about the other biological parent, not the child's age.

Residency and timing: Because there is no minimum residency period, you do not have to wait to build up time in the state before filing. If you have a question about timing that is specific to a very young baby, the District Court clerk in your county can confirm it.

The child's consent: Montana's child consent age is 12 (Mont. Code Ann. § 42-2-301). A newborn or infant is well under that age, so the child's own consent is not part of your case.

The other biological parent: This is where a newborn case can differ from an older child's case. Montana's abandonment period is 6 months (Mont. Code Ann. § 42-2-608). With a very young baby, that much time may not have passed. Whether the other parent must consent, and whether anything else applies, depends on your facts. That is especially true if the other parent is unknown, unreachable, or may object. Please ask the District Court clerk or an attorney about your specific situation.

Home study: Montana waives the home study in stepparent adoptions (Mont. Code Ann. § 42-4-309). That removes a step that can add time to other kinds of adoption.

What to expect:

• Court: District Court in your county.
• Timeline: Stepparent adoptions in Montana typically take 3-6 months.
• Court fees: These are set by the court, so the clerk in your county can tell you the current amount.
• Birth certificate: The Montana Office of Vital Statistics is the agency to contact about the child's birth record once the adoption is final.

Why some families move early: Adopting while your child is an infant means your legal relationship is settled from the start. That can matter for things like medical decisions and insurance. The right timing for your family depends on your circumstances, including the other parent's situation.
