In Michigan, both spouses are equally protected if the property is their established 'homestead' (also known as Principal Residence). Otherwise, they would not have any protection as to ownership in the property. So, you could mortgage or cash out an investment property with impunity, but not the family residence.

Of course, the divorce attorneys will claim foul and go after the proceeds, just as they have always done for 'undisclosed assets'.
