Can a stepparent adopt a child born out of wedlock in Missouri?

Yes. A stepparent can ask a Missouri Circuit Court to approve the adoption of a child born out of wedlock. What shapes your case is the legal position of the child's other parent, not whether your spouse and that parent were married when the child was born.

What the birth circumstances can affect: Your situation may look like one of these:

• The other parent is named on the birth certificate.
• The other parent is not named.
• The other parent's identity is unknown.

How a Missouri court handles each of these, including who must be notified or must consent, depends on the facts. Please confirm that point with the Circuit Court clerk in your county or with an attorney. This matters most if the other parent might object, because a contested case is a question for an attorney.

Missouri points that apply to your family:

• Court: Your petition is filed in the Circuit Court. Missouri has 115 counties, and your county's clerk can explain local filing steps.
• Residency: Missouri has no minimum residency period for adoption (RSMo § 453.010).
• Your child's consent: The age for a child's own consent is 14 (RSMo § 453.030). If your child is younger, ask the clerk how that applies to you.
• Abandonment: If your case involves the other parent's rights on abandonment grounds, Missouri's provision (RSMo § 453.040) refers to a 6-month period. Whether your facts fit is a question for the clerk or an attorney.
• Home study: Missouri waives the home study for stepparent adoptions (RSMo § 453.070).
• Background check: Missouri requires a criminal background check for the stepparent.
• Birth records: Birth certificates are kept by the Missouri Department of Health and Senior Services Bureau of Vital Records. It helps to look at your child's certificate first, so you know which situation above you are in.

Timeline and cost: A stepparent adoption in Missouri typically takes about 3-6 months. Court filing fees generally run $200-$500, and the total cost is typically under $1,000. Hiring an attorney commonly costs $3,000-$5,000+.

Where to start: Get a copy of the birth certificate and write down what you know about the other parent: whether they are named, whether they have been involved, and when you last had contact. Having those facts ready makes it easier to talk with the court clerk or an attorney about notice and consent.
