Exhibit 31-1
                                 CERTIFICATIONS

I, Wilfred N. Cooper, Jr., certify that:

1. I have reviewed this quarterly  report on Form 10-Q of WNC HOUSING TAX CREDIT
   FUND VI, L.P., SERIES 12;

2. Based on my  knowledge,  this  annual  report  does  not  contain  any untrue
   statement of a material fact or omit to state a material  fact  necessary  to
   make the statements made,  in light of the  circumstances  under  which  such
   statements were made,  not  misleading  with  respect  to the period  covered
   by this annual report;

3. Based  on  my  knowledge,  the  financial  statements,  and  other  financial
   information  included  in this annual report, fairly  present in all material
   respects the financial condition, results of operations and cash flows of the
   registrant as of, and for, the periods presented in this annual report;

4. The   registrant's  other  certifying  officer  and  I  are  responsible  for
   establishing and maintaining  disclosure  controls and procedures (as defined
   in Exchange Act Rules 13a-15e and 15d-15e) for the registrant  and  we  have:

   (a)  Designed  such  disclosure  controls  and  procedures,  or   caused such
        disclosure   controls  and   procedures  to   be   designed   under  our
        supervision,  to ensure  that   material  information  relating  to  the
        registrant,  including its consolidated subsidiaries, is  made  known to
        us by others within those entities,  particularly during the  period  in
        which this annual report is being prepared;

   (b)  Evaluated the  effectiveness of  the  registrant's  disclosure  controls
        and procedures and presented in this  report  our conclusions  about the
        effectiveness of the disclosure controls   and procedures, as of the end
        of the period covered  by  this report based   on such  evaluation;  and

   (c)  Disclosed  in  this  report  any  change  in the  registrant's  internal
        control over financial reporting that occurred during  the  registrant's
        most   recent   fiscal  quarter  that  has  materially  affected,  or is
        reasonably  likely  to  materially  affect,  the  registrant's  internal
        control over financial reporting; and

5. The registrant's other certifying  officer(s) and I have disclosed,  based on
   our most recent evaluation of internal control  over financial reporting,  to
   the registrant's  independent registered public accounting firm and the audit
   committee of the registrant's board of directors (or persons  performing  the
   equivalent functions):

   (a)  All significant  deficiencies and  material  weaknesses in the design or
        operation  of  internal  control  over  financial  reporting  which  are
        reasonably  likely  to  adversely affect in the registrant's  ability to
        record,  process,  summarize  and   report  financial  information;  and

   (b)  Any fraud, whether or not material,  that involves management  or  other
        employees who have a  significant  role  in  the  registrant's  internal
        control over financial reporting.
