how did the divorce decree address splitting of the rental properties?
if you both still own them, there could be complications.
this is because if you each have and ownership interest in a property, now being divorced, may require the filing of partnership returns.
here's what the IRS says
A joint undertaking merely to share
expenses isn't a partnership. Mere
co-ownership of property that is maintained
and leased or rented isn't a partnership.
However, if the co-owners provide services
to the tenants, a partnership exists.
