Can one person in a marriage declare bankruptey in the state of Texas without the other married partner?

Yes. One spouse may file without the other spouse also filing.  This may be tricky, however, with regards to martial debts.  You should contact a local bankruptcy attorney to determine if bankruptcy would be appropriate in this case.
