Stepparent Adoption in South Dakota: Overcoming an Absent Biological Parent's Refusal

Current as of: October 7, 2026 Adoption Law South Dakota
In South Dakota, you can adopt your stepchild even if the biological parent refuses to consent. Under S.D. Codified Laws § 25-6-4, a judge can waive their consent if they have abandoned the child for at least six months or willfully failed to pay child support.

Blended families are common, and for many stepparents in South Dakota, adopting their spouse's child is a profound way to solidify their family unit. However, the legal process can stall if the absent biological parent refuses to sign a consent form, often out of spite or a sudden renewed interest. Fortunately, South Dakota law provides a clear path to bypass an absent parent's refusal. Whether you live in Sioux Falls, Aberdeen, or Mitchell, understanding the state's rules on abandonment is the key to finalizing a stepparent adoption.

Step-by-Step Process in South Dakota

Stepparent adoptions are finalized in the Circuit Court of the county where the child lives. For example, families in Aberdeen will file their paperwork at the Brown County Circuit Court, Aberdeen, while those in Mitchell will use the Davison County Circuit Court, Mitchell. You will start by filing a formal petition, which your attorney will draft, often utilizing the framework of Form UJS-354, South Dakota, Unified Judicial System, Mandatory Reporting Form for All Adoption Cases.

Proving Abandonment and Failure to Support

If the absent parent will not consent, you must prove to the court that their consent is no longer legally required. Under S.D. Codified Laws § 25-6-4, a judge can waive the biological parent's consent and allow the adoption if the parent has abandoned the child for six months or more immediately prior to the filing of the petition. South Dakota courts also recognize willful failure to pay court-ordered child support or provide necessary care as strong statutory grounds to waive consent. You must provide the court with clear and convincing evidence, such as financial records from the Department of Social Services showing zero support payments, or testimony regarding the total lack of phone calls, visits, or letters.

When the Biological Father is Incarcerated

A frequent challenge arises when the biological father is in prison. Incarceration alone does not automatically constitute abandonment under South Dakota law. However, if the father made no effort to maintain a relationship with the child before going to prison, or failed to communicate with the child while incarcerated, a judge may rule that abandonment occurred. The South Dakota Supreme Court reinforced this standard in Matter of B.A.M., 290 N.W.2d 498 (SD Supreme Court 1980), noting that an incarcerated parent must still make reasonable attempts to be a parent under the circumstances.

Serving Legal Notice to an Out-of-State Parent

Even if the absent parent has not seen the child in five years and lives in another state, the US Constitution requires that they be given formal legal notice of the adoption hearing. You must hire a process server to hand-deliver the legal summons to them. If you cannot find them because they are hiding or transient, your lawyer can ask the South Dakota judge for permission to serve notice by publication. This involves publishing a formal legal notice in a local newspaper where the parent was last known to live for several consecutive weeks.

Waiving the Home Study for Stepparents

In traditional adoptions, families must undergo an expensive and invasive home study by a licensed social worker. However, South Dakota law is highly favorable to stepparents. Under S.D. Codified Laws § 25-6-10, the judge has the discretion to waive the mandatory home study report entirely for stepparent adoptions, saving your family thousands of dollars and months of waiting.

How Much Does a Stepparent Adoption Cost?

Because you can often waive the home study, stepparent adoptions are generally the most affordable type of adoption in South Dakota.

Adoption ExpenseEstimated Cost in South Dakota
Circuit Court Filing Fee$72
Process Server / Publication Fees$75 to $300
New Birth Certificate Fee (SD Dept of Health)$15
Attorney Fees (Contested vs. Uncontested)$1,500 to $4,500

If the absent parent contests the adoption and fights you in court, attorney fees will be on the higher end of the spectrum. You can find experienced family law attorneys in our US Lawyers catalog to help assess your specific case.

How Long Does the Process Take?

If the absent parent cannot be found and you must use publication, the process takes roughly 3 to 5 months. If the parent voluntarily signs the consent form early on, a stepparent adoption in South Dakota can be finalized by a judge in as little as 60 to 90 days.

Frequently Asked Questions (FAQ)

Do we have to be married for me to adopt my stepchild?

Yes. South Dakota law requires the stepparent to be legally married to the child's custodial biological parent in order to file a stepparent adoption petition.

Will the absent parent still have to pay back-owed child support?

Once the adoption is finalized, the absent parent's future obligation to pay child support ends. However, they may still be legally liable for past-due (arrears) child support owed to your spouse prior to the adoption date.

Can the child's last name be changed during the adoption?

Absolutely. The petition for adoption includes a request to officially change the child's name, and a new birth certificate will be issued by the state upon finalization.
