(a) A gift of all or part of the body under subsection (a) of Section 22-19-42 may be made by will. The gift becomes effective upon the death of the testator without waiting for probate. If the will is not probated, or if it is declared invalid for testamentary purposes, the gift, to the extent that it has been acted upon in good faith, is nevertheless valid and effective.

(b) A gift of all or part of the body under subsection (a) of Section 22-19-42 may also be made by document other than a will. The gift becomes effective upon the death of the donor. The document, which may be a card designed to be carried on the person, must be signed by the donor in the presence of two witnesses, who must sign the document in his presence. If the donor cannot sign, the document may be signed for him at his direction and in his presence and in the presence of two witnesses, who must sign the document in his presence. Delivery of the document of gift during the donor's lifetime is not necessary to make the gift valid.

(c) The gift may be made either to a specified donee or without naming a donee. If the donee is not named, the attending physician may accept as donee upon or following death. If the gift is made to a specified donee who is not available at the time and place of death, the attending physician may, in the absence of any expressed indication that the donor desired otherwise, accept the gift as donee. The physician who becomes a donee under this subsection shall not participate in the procedures for removing or transplanting a part.

(d) The donor may designate in his will, card or other document of gift the surgeon or physician to carry out the appropriate procedures. In the absence of a designation, or if the designee is not available, the donee or other person authorized to accept the gift may comply or authorize any surgeon or physician for the purpose.

(e) Any gift by a person designated in subsection (b) of Section 22-19-42 shall be made by a document signed by him or made by his telegraphic, recorded telephonic or other recorded message.
