Proving Legal Parentage for Inheritance in South Dakota: What to Do When Dad’s Name Isn’t on the Birth Certificate

This page explains how someone born in South Dakota can prove they are their father’s child for purposes of inheritance when the father’s name does not appear on the birth certificate. It explains the typical legal routes, the evidence courts accept, and practical next steps. This is educational information only and is not legal advice.

How South Dakota law treats children and intestate inheritance

When a person dies without a valid will, South Dakota’s probate (intestate succession) rules determine who inherits. Those rules look to legal parent-child relationships, not solely the name on the birth certificate. For the statutes governing intestate succession and probate procedure, see South Dakota’s probate laws: SDCL Title 29A (Probate).

Why a birth certificate alone isn’t definitive

A birth certificate is important but not conclusive proof of legal parentage. South Dakota (and its courts) will accept other forms of proof—voluntary acknowledgments, genetic testing, courtroom findings of paternity, and other evidence of parentage—when deciding who qualifies as an heir.

Common legal ways to establish parentage in South Dakota

• Voluntary Acknowledgment of Paternity (AOP): If the father previously signed a sworn acknowledgment of paternity (often filed with the birth record), that document usually creates legal parentage.
• Genetic (DNA) testing: DNA tests are commonly accepted as strong proof. Courts can order DNA tests of the claimant and available relatives of the decedent (other children, siblings, or the decedent’s stored biological material). A court-ordered test is typically admissible in probate or paternity proceedings.
• Court adjudication of paternity: You can ask a family court or the probate court handling the estate to declare you the decedent’s child. The court can evaluate DNA results and other evidence and enter a legal finding of parentage.
• Other evidentiary proof: When DNA is not possible, courts may consider hospital records, medical records, school records, photographs, correspondence, affidavits from witnesses who knew the family relationship, proof that the decedent publicly recognized or supported you (e.g., provided financial support), or testimony that you were treated as the decedent’s child.

Steps to take if the father is deceased and his name isn’t on your birth certificate

1. Get copies of key documents: Obtain your certified birth certificate, the decedent’s death certificate, and any probate case number or estate paperwork if an estate has been opened.
2. Look for an Acknowledgment of Paternity: Contact the South Dakota Department of Health (vital records) to learn whether an AOP was filed that might already establish parentage. South Dakota Vital Records: doh.sd.gov Vital Records.
3. Gather supporting evidence: Collect photos, letters, school or medical records, affidavits from relatives or friends, financial records showing support, or any documents where the decedent identified you as their child.
4. Consider DNA testing: If possible, obtain DNA from living relatives of the decedent (other children, siblings, or parents). If the decedent’s body or tissue or stored medical samples exist, the court can sometimes authorize testing (which may require a formal order and permission of the decedent’s estate or next of kin).
5. File the right court action: If an estate is open, file a petition in the probate court asking the court to determine heirs or to admit you as an heir. If no estate is open, you may need a separate action to establish paternity or to open an estate and assert heirship. South Dakota courts: South Dakota Unified Judicial System.
6. Act promptly: Timely action is important. If an estate has already been closed or distributed, you may need to ask the court to reopen the estate or file a claim against current distributees. Courts sometimes impose deadlines and procedural requirements limiting late claims.

Practical issues when DNA testing is needed but the father is dead

• If a direct sample from the decedent isn’t available, a court can allow testing of the decedent’s biological relatives (e.g., other children, siblings, or parents) to establish genetic relationships.
• Testing from items of the decedent (toothbrush, hairbrush, medical tissue) may be possible but often requires court authorization and chain-of-custody proof.
• Exhumation for DNA testing is sometimes an option but involves additional legal steps, permissions, and costs.

What a probate court will evaluate

The probate court will consider: (1) whether you are the decedent’s legal child under state law; (2) any wills or estate planning documents the decedent left; and (3) the credibility and sufficiency of the evidence (DNA is usually the most persuasive). The court can enter an order recognizing you as an heir if the evidence supports parentage.

See South Dakota probate statutes for the court’s authority and procedures: SDCL Title 29A (Probate).

When to consult an attorney

• If the estate is contested, valuable, or already closed.
• If you need a court-ordered DNA test or permission to test the decedent’s remains or personal items.
• If you aren’t sure which court to file in or face deadlines or complex evidentiary disputes.

An attorney experienced in South Dakota probate and parentage matters can explain filing deadlines, prepare petitions to determine heirs or establish paternity, and help obtain DNA or other evidence.

Helpful Hints

• Start by requesting certified copies of your birth certificate and the decedent’s death certificate from South Dakota Vital Records: doh.sd.gov Vital Records.
• Search family files for any signed acknowledgments, letters, tax records, or documents where the decedent named you as a child; these can help build your case.
• If you can locate other biological relatives of the decedent, contact them about voluntary DNA testing—this can be faster and less expensive than court-ordered testing.
• Keep a careful chain-of-custody for any physical samples (hairbrush, toothbrush) and consult counsel before attempting to use personal items for testing.
• If an estate is already closed, ask an attorney whether you can reopen the estate or file a late claim; timing rules vary and courts look at the reasons for delay.
• Document everything: who you spoke with, dates, what documents you obtained, and copies of requests you filed with agencies or courts.
