Mich. Comp. Laws § 450.4504: Membership interest as personal property.

Sec. 504.

A membership interest is personal property and may be held in any manner in which personal property may be held. A husband and wife may hold a membership interest in joint tenancy in the same manner and subject to the same restrictions, consequences, and conditions that apply to the ownership of real estate held jointly by a husband and wife under the laws of this state, with full right of ownership by survivorship in case of the death of either.

A member has no interest in specific limited liability company property.
