South Dakota counties give you free certified copies of birth, death, marriage, adoption, divorce, guardianship and conservatorship records when you need them for a state or federal benefits claim.
Ask the county office that holds the record for a certified copy and tell them it is for a state or federal veterans benefits claim. A county or tribal veterans service officer can help you request it.
Proof of your service or your relationship to the service member, and an explanation of the benefits claim the record is needed for.
