What if the biological parent lives in Missouri but I live in another state?

Missouri has no minimum residency period for a stepparent adoption (RSMo § 453.010), but whether your case belongs in a Missouri Circuit Court or in your own state's court depends on facts like where you and the child live. Confirm that with the Circuit Court clerk in the Missouri county involved, or with an attorney, before you file.

Why the other parent's address matters less than you might think: The biological parent living in Missouri does not by itself decide where the adoption is filed. The court's location turns on your family's situation, including where you and the child live. Because that is a fact-specific question, a short call to the Circuit Court clerk or an attorney is worth it before you commit to a court.

If your case is filed in Missouri, here is what to expect:

• Court: The Circuit Court in the county where the case is filed. Missouri has 115 counties, and each clerk can explain local filing steps.
• Residency: Missouri sets no minimum residency period (RSMo § 453.010).
• Child's consent: A child who is 14 or older must consent (RSMo § 453.030).
• Parent's consent or abandonment: If the biological parent will not sign consent, Missouri's abandonment period is 6 months (RSMo § 453.040). Whether that applies to your family depends on your facts, so a contested case or a parent you cannot locate is a question for an attorney.
• Home study: Missouri waives the home study in stepparent adoptions (RSMo § 453.070).
• Timeline: Stepparent adoptions in Missouri typically take 3-6 months.
• Costs: Court filing fees run about $200-$500, and the total typically comes to under $1,000, compared with $3,000-$5,000+ for an attorney.

Working with a parent in another state: Missouri's law does not spell out the mechanics of getting a consent signed or of serving papers on a parent who lives in Missouri while you live elsewhere.
