Taxability of 2 house properties co-owned by husband-wife

Dear Sirs , 

             I wanted to know want will be the Taxability in case there are 2 House Properties being jointly Co-owned (50% share each) by Husband & wife.

   1) Can each one claim one house ,  as Self-Occupied Property in thier return (if it is not let out) ?

   2) In case one of the house is given/let-out  on rent , in how will such rental income be taxed and that too in whose hands ?

         Kindly advise

Thanks
