Can I adopt my stepchild if there is an existing custody order in Montana?

Yes. An existing custody order does not stop you from filing a stepparent adoption petition in your Montana District Court. The order is simply one of the facts the court will want to know about, so plan to bring a copy.

What to expect with a custody order in place:

• Adoption petitions are filed in the District Court. Include a copy of the custody order and any related orders, such as parenting plans or child support, so the court has the full picture.
• How the court will handle the existing custody and support terms once an adoption is final depends on your situation. The District Court clerk in your county or a Montana family attorney can tell you exactly how that works for your order.
• Until a judge approves the adoption, treat the current order as the one that governs your family.

Where the other parent stands matters most. The custody order tells the court who has been involved, but the adoption itself turns on the other legal parent's consent or on the grounds for proceeding without it.

• If the other parent agrees, that is typically the simplest path.
• If the other parent has not been involved, Montana sets a six-month abandonment period under Mont. Code Ann. § 42-2-608. Whether your facts meet that standard is a question for the court, so an attorney can advise you on a contested or unclear situation.
• If you don't know where the other parent is, or the case is contested, talk to an attorney about that specific issue.
• Montana does not treat termination of the other parent's rights as a separate case in a stepparent adoption.

Other Montana points that apply:

• Residency: Montana has no minimum residency period for filing. See Mont. Code Ann. § 42-1-104(1).
• Child's consent: The consent age is 12 under Mont. Code Ann. § 42-2-301. If your stepchild is 12 or older, the child's consent is part of the process.
• Home study: Montana waives the home study for stepparent adoptions under Mont. Code Ann. § 42-4-309.
• Timeline: Stepparent adoptions in Montana typically take 3-6 months. A contested case or complicated order history can affect that, and the clerk can tell you about local scheduling.
• Court fees: The filing fee is set by the District Court, so ask the clerk in your county for the current amount.

Questions to ask the clerk or an attorney:

• Does the court want the custody order attached in a particular form?
• What happens to parenting time and child support terms when the adoption is approved?
• Is any additional notice needed to the other parent given your order?
