Can my spouse adopt my child from a previous relationship in Missouri?

Yes, your spouse can adopt your child from a previous relationship in Missouri. Stepparent adoption is handled by the Circuit Court (juvenile division) in your county, and Missouri's process for it is fairly straightforward.

What Missouri requires

• Residency: Missouri sets no minimum residency period under RSMo § 453.010, so you do not have to wait before filing.
• Your child's consent: If your child is 14 or older, their consent comes into play under RSMo § 453.030.
• The other biological parent: This is usually the most important question in a stepparent adoption. The other parent's consent is typically involved, and Missouri also addresses abandonment, with a 6-month period in RSMo § 453.040. Whether that applies to your situation depends on your facts, so ask the Circuit Court clerk or an attorney if the other parent is unknown, unreachable, or likely to object.
• Background check: Missouri requires a criminal background check for the stepparent, to protect the child's safety.
• Home study: Missouri waives the home study for stepparent adoptions (RSMo § 453.070).

What the court does

Your spouse files a petition in the Circuit Court, and the court holds a hearing to decide whether to finalize the adoption. Once it is finalized, your spouse becomes your child's legal parent. That brings inheritance rights, the authority to make medical decisions, and possible eligibility for Social Security survivor benefits and insurance coverage.

How long it takes

A stepparent adoption in Missouri typically takes about 3-6 months. Contested cases or cases with a missing parent may take longer, and your county's clerk can tell you about local scheduling.

What it costs

Court filing fees generally run $200-$500, and the total typical cost is under $1,000. Hiring an attorney for the whole process often costs $3,000-$5,000+. Your county clerk can confirm the exact filing fee.

After the adoption

Many families also want an updated birth certificate. The Missouri Department of Health and Senior Services Bureau of Vital Records handles birth records, and the clerk can explain what to bring to them once your adoption is final.

When to get individual help

If the other parent has not agreed, cannot be found, or has not been in contact, the outcome depends on the details. The Circuit Court clerk or a Missouri family law attorney can advise you on that specific issue.
