S.D. Codified Laws § 55-11-11
A prearranged funeral contract pooled funds trust may be created by a funeral director or a funeral establishment licensed in South Dakota, the South Dakota funeral directors association or a cemetery association organized under chapter 55-12. However, separate accounts within the pooled funds trust shall be maintained so that a purchaser whose money has been deposited into the pooled funds trust may identify his money. No purchaser's money may be deposited into a pooled funds trust unless the purchaser signs a form consenting to the deposit of his money into a pooled funds trust. The provision regarding consent shall not apply to prearranged funeral trusts where the personal property and professional services are to be provided for a guaranteed amount of money.
