Michigan Compiled Laws, Chapter 700. Estates and Protected Individuals Code § 700.2718

Sec. 2718. (1) If an applicable statute or a governing instrument calls for the property to be distributed “by representation” or “per capita at each generation”, the property is divided into as many equal shares as there are surviving descendants in the generation nearest to the designated ancestor that contains 1 or more surviving descendants and deceased descendants in the same generation who left surviving descendants, if any. Each surviving descendant in the nearest generation is allocated 1 share. The remaining shares, if any, are combined and then divided in the same manner among the surviving descendants of the deceased descendants as if the surviving descendants who were allocated a share and their surviving descendants had predeceased the distribution date. This rule of construction applies to documents originally created on and after April 1, 2000, and to all instruments amended on and after April 1, 2000, that use the phrase “by representation” or “per capita at each generation”. If an amendment uses either phrase, the rule of this section applies to the entire instrument.

(2) If a governing instrument calls for property to be distributed “per stirpes”, the property is divided into as many equal shares as there are surviving children of the designated ancestor and deceased children who left surviving descendants. Each surviving child, if any, is allocated 1 share. The share of each deceased child with surviving descendants is divided in the same manner, with subdivision repeating at each succeeding generation until the property is fully allocated among surviving descendants.

(3) For the purposes of subsections (1) and (2), a deceased individual who left no surviving descendant is disregarded, and an individual who leaves a surviving ancestor who is a descendant of the designated ancestor is not entitled to a share.

(4) As used in this section:
