How to Disestablish Paternity and Fight Paternity Fraud in South Dakota

Discovering that you are not the biological father of a child you have been raising is a deeply traumatic experience. This situation, often referred to as paternity fraud, carries massive emotional and financial consequences. In South Dakota, the law strongly favors stability for the child, which means the courts make it intentionally difficult to strip away a man's legal status as a father once it has been established. If you are paying child support for a child that is not biologically yours, you cannot simply stop paying; you must formally disestablish paternity through the legal system.

Fighting to remove your name from a birth certificate or to vacate a child support order is one of the most complex areas of family law. The statutes of limitations are brutal, and missing a deadline can lock you into a financial obligation until the child turns 18. Connecting with a fierce family law attorney from our United States lawyer directory is the most effective way to navigate the South Dakota Circuit Courts and protect your future.

Step-by-Step Process in South Dakota

Whether your case is handled in Sioux Falls, Rapid City, or Aberdeen, you must follow a rigid legal process to challenge paternity. Delaying action can destroy your case.

Step 1: Revoking a VAP (Within 60 Days)

If you recently signed an Affidavit Acknowledging Paternity at the hospital, S.D. Codified Laws § 25-8-59 allows you to rescind the document within 60 days of signing, or before the first administrative or judicial proceeding related to the child (whichever comes first). You must submit a formal rescission form to the South Dakota Department of Health, Pierre.

Step 2: Filing a Petition to Disestablish

If the 60-day window has passed, or if paternity was established by marriage or a prior court order, you must file a formal Petition to Disestablish Paternity at a local court, such as the Brown County Circuit Court, Aberdeen. You must state the specific legal grounds for your challenge.

Step 3: Presenting DNA Evidence

To win your case, you will almost certainly need a court-admissible DNA test proving you are not the biological father. Over-the-counter kits are not accepted as formal evidence but can be used to convince the judge to order an official test.

Step 4: The Evidentiary Hearing

You and your lawyer will attend a hearing to prove that the initial establishment of paternity was based on fraud, duress, or a material mistake of fact. If successful, the judge will issue an order vacating your legal status as the father and terminating future child support.

Contesting a Birth Certificate After Several Years

If you signed a VAP years ago and just now discovered you are not the biological father, your legal hurdle is incredibly high. Under South Dakota law, once the 60-day rescission period expires, you can only challenge the acknowledgment in court on the basis of fraud, duress, or a material mistake of fact. Furthermore, the burden of proof is entirely on you. You must prove that the mother intentionally lied to you about the child's parentage to trick you into signing the document. As demonstrated in appellate cases like Culhane v. Michels, 615 N.W.2d 580 (SD Supreme Court 2000), courts are hesitant to sever the father-child relationship if a man has willingly acted as the father for many years.

Handling DNA Test Results and the Marital Presumption

If you were married to the mother when the child was born, S.D. Codified Laws § 25-8-57 legally presumes you are the father. If you later get divorced and subsequently discover via a DNA test that you are not the biological father, you must file a motion to set aside the paternity determination in your divorce decree. South Dakota imposes strict statutes of limitations on reopening old court judgments. Generally, you must act almost immediately after discovering the evidence of non-paternity. Failing to act quickly after getting a negative DNA test can result in the court ruling that you have 'acquiesced' to being the legal father, permanently locking in your child support obligations.

How Much Does it Cost in South Dakota?

Rescinding a VAP within 60 days typically involves only minimal administrative fees with the Department of Health. However, filing a formal lawsuit to disestablish paternity years later is expensive. Court filing fees range around $100, and mandatory legal DNA testing costs $300 to $500. Because these cases require proving fraud and overcoming strong legal presumptions, attorney fees can easily range from $3,500 to $7,500 or more, depending on how aggressively the mother or the state fights your petition.

How Long Does the Process Take?

A simple 60-day rescission can be processed in a matter of weeks. A full court battle to disestablish paternity based on fraud is a lengthy process. Gathering evidence, serving the mother, attending hearings, and waiting for the judge's final ruling typically takes anywhere from 6 to 12 months in the South Dakota Circuit Court system.
