Can anyone tell me what the rules around dower rights are in Michigan? Thanks.

I would check the Michigan Legislature site: http://www.legislature.mi.gov/(S(zdq4pi45hyvhoy45e20h5f55))/mileg.aspx?page=MCLIndex&objectname=mcl-chap558

I do know that they can not be waived, we used to do this in Ohio when i work there years ago, but i learned that MI will not allow a spouse to sign off their dower interest.
