SDCL § 23A-22-16: Proof of marriages in bigamy prosecutions.

In prosecutions for bigamy, it is not necessary to prove either of the marriages by the register, certificate, or other record evidence thereof, but they may be proved by such evidence as is admissible to prove a marriage in other cases, and when the second marriage took place out of this state, proof of that fact, accompanied with proof of cohabitation thereafter in this state, is sufficient to sustain the charge.
