What if the biological parent lives in another state — can I still adopt in Illinois?

Yes. In Illinois you can file a stepparent adoption in the Circuit Court even if the child's other biological parent lives in another state. Distance alone doesn't change the basic path, and several Illinois rules work in your favor.

Residency: Illinois has no residency waiting period for a stepparent adoption. The 6-month rule does not apply to a related child (750 ILCS 50/2). You don't need to wait before filing.

Where you file: Stepparent adoptions are filed in the Circuit Court. The Circuit Court clerk in your county can tell you which courthouse handles your case and what local filing steps apply.

What an out-of-state parent changes: The main practical questions are how the other parent receives notice and how their consent or response is handled. Those details depend on your facts, such as whether the parent is cooperative, hard to reach, or opposed. Confirm the exact steps for an out-of-state parent with the Circuit Court clerk or an attorney.

Related Illinois rules that may apply:

• Abandonment: Illinois sets a 12-month period relating to abandonment (750 ILCS 50/1). Whether a parent's situation meets it depends on the specific history, so it's worth a conversation with the clerk or an attorney.
• Child's consent: A child who is 14 or older has a consent role in the adoption (750 ILCS 50/12).
• Home study: Illinois does not require a home study for most stepparent adoptions (750 ILCS 50/6).
• Unknown location: Illinois has procedures for cases where the other parent cannot be located. If you don't know where the parent is, the court process for that situation is the one to ask about.

If the other parent objects: A contested case turns on its particular facts, and a family law attorney can advise you on that. The distance between you and the other parent doesn't settle it either way.

Timeline and cost: A stepparent adoption in Illinois typically takes 3-6 months. Court filing fees generally run $200-$500, depending on the county. An attorney for the whole process often costs $3,000-$5,000+, which is why many families prepare and file the paperwork themselves.
