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.
