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 13;

2. Based on my  knowledge,  this  quarterly  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 quarterly report;

3. Based  on  my  knowledge,  the  financial  statements,  and  other  financial
   information included in this quarterly report, fairly present in all material
   respects the financial condition, results of operations and cash flows of the
   registrant as of, and for, the period  presented in  this  quarterly  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-15(e) and 15d-15(e))for the registrant and we have:

   (a)  Designed   such  disclosure  controls  and  procedures  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  quarterly
        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 auditors and the audit committee of  the registrant's  board
   of directors (or persons performing the equivalent functions):

   (a)  All  significant  deficiencies  in the design or operation  of  internal
        controls  which  could  adversely  affect the  registrant's  ability  to
        record,   process,   summarize  and  report  financial  data  and   have
        identified for the  registrant's  auditors any  material  weaknesses  in
        internal controls; 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.
