S.D. Codified Laws § 34-25-52.7
Notwithstanding § 34-25-52, the department must provide, at no cost, a certified copy of a person's South Dakota birth certificate, limited to one, upon application and proof of that person's homelessness. The person or the person's spouse, child, parent, guardian, next of kin, or authorized representative may apply for a certified copy of the person's birth certificate pursuant to this section.
An affidavit developed by the department attesting to the person's housing status is proof of homelessness for the purposes of this section. The department may not accept an affidavit as proof of homelessness unless signed by the person experiencing homelessness and a homeless services provider with knowledge of the person's housing status.
For the purposes of this section, the term "homeless services provider" means any government or nonprofit agency that provides a food bank, homeless shelter, housing assistance program, homeless outreach or advocacy program, or any similar program; any human services or social services agency, public or private, providing health services, behavioral health services, substance use disorder services, or employment or public assistance services to homeless persons; or any law enforcement officer designated as a liaison to the homeless population by a local police department or sheriff's department.
