Yes. Missouri has a few requirements to know about for stepparent adoption, but the process is fairly straightforward, and the home study is waived for stepparents. Here is what to expect.

Where you file: Your petition goes to the Circuit Court in your Missouri county. Missouri has 115 counties, and the Circuit Court clerk in yours can confirm local filing details.

Residency: Missouri has no minimum residency period for adoption (RSMo § 453.010). You do not have to wait a set number of months before filing.

Home study: For stepparents, the home study is waived (RSMo § 453.070). That removes a step that can add time and cost in other kinds of adoption.

Child's consent: If the child is 14 or older, the child's consent is part of the process (RSMo § 453.030). Children under 14 do not have a consent requirement.

Background checks: Missouri requires background checks to protect children, including a criminal background check for the stepparent. Your Circuit Court clerk can tell you exactly which checks your county expects and how to complete them.

Abandonment period: Missouri's abandonment period is 6 months (RSMo § 453.040). It can matter if the other legal parent is absent and not involved. Whether it applies to your family depends on your specific facts, so if the other parent is unknown, unreachable, or likely to object, ask the Circuit Court clerk or an attorney about that issue.

Forms and wording: Missouri courts require specific forms and language, and the paperwork has to be correct to be accepted. Mistakes in the documents are a common reason filings are sent back, so accuracy matters more than speed here.

Timeline and cost:

  • A stepparent adoption in Missouri typically takes 3-6 months.
  • Court filing fees run about $200-$500, and the total typical cost is under $1,000.
  • Hiring an attorney for the whole process often runs $3,000-$5,000+.

If you are adopting an adult: Missouri allows adult adoption. An adult adoptee's written consent alone is sufficient, and the process typically takes 4-8 weeks. The court holds a hearing before finalizing. Questions about who may be adopted in your particular situation are best confirmed with the Circuit Court clerk or an attorney.

Contested or unusual situations: If the other parent disagrees, cannot be found, or your family's circumstances are complicated, the outcome depends on the facts. An attorney can advise you on that specific issue.
