Can I adopt my stepchild if they live with the other biological parent part-time in Maine?

It may be possible, but the other parent's part-time role is the key question, and the answer depends on the facts of your family. Where your stepchild sleeps does not settle it on its own, so it helps to know what Maine's rules do say.

What Maine's rules say:

• Court: Stepparent adoptions are filed in the Probate Court in your county. Maine has 16 counties, and each has its own Probate Court.
• Residency: Maine has no minimum residency period before you can file (18-C M.R.S. § 9-301).
• Child's consent: A child who is 12 or older has a consent requirement (18-C M.R.S. § 9-302).
• Abandonment: Maine sets a 6-month period for abandonment (18-C M.R.S. § 9-204; 22 M.R.S. § 4002(1-A)).
• Home study: Maine waives the home study in stepparent adoptions (18-C M.R.S. § 9-304).
• Timeline: Stepparent adoptions in Maine typically take 3-6 months.

Why part-time custody matters: When the other biological parent has the child part of the time, that parent is clearly still in the child's life. The abandonment period is not a good fit for a parent who is regularly involved, so you should not plan around it unless the facts truly support it. Whether that parent's consent is needed, and what happens if they disagree, are questions to confirm with the Probate Court clerk in your county or with a Maine family law attorney. That is especially true if the other parent objects or you expect a dispute.

Practical steps to consider:

• Talk with the other parent. Many families start by finding out whether the other parent supports the adoption, and how they feel about the child's relationship with you.
• Write down your custody arrangement. Note any existing court order, the parenting schedule, and how involved each household is. This will help the clerk or an attorney give you accurate guidance.
• Think about your child's voice. If your stepchild is 12 or older, their consent is part of the process.
• Ask the clerk about fees and forms. The Probate Court clerk in your county can confirm the filing fee and any local filing practices.

If the other parent agrees and the situation is straightforward, the paperwork is usually the main task. If the other parent's role is uncertain or disputed, an attorney can advise you on your specific circumstances before you file.
