Mich. Comp. Laws § 700.2909: Persons bound; effect of disclaimer.

Sec. 2909.

A disclaimer, or a written waiver of the right to disclaim, is binding upon the disclaimant or person waiving the right to disclaim, and all persons claiming through or under him or her.

A disclaimer acts as a nonacceptance of the disclaimed interest, rather than as a transfer of the disclaimed interest. The disclaimant is treated as never having received the disclaimed interest.
