EXHIBIT 31.2

                                  CERTIFICATION

I, Stanley P. Wirtheim, certify that:

1.   I have reviewed this quarterly report on Form 10-QSB of SmartPros Ltd.;

2.   Based on my knowledge, this report does not contain any untrue statement of
     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
     report;

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

4.   The  small  business  issuer's  other  certifying   officer(s)  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 small business issuer and 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
               small business issuer, including its consolidate subsidiaries, is
               made known to us by others  within those  entities,  particularly
               during the period in which this report is being prepared;

          b)   Evaluated  the  effectiveness  of  the  small  business  issuer'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  small  business
               issuer's internal control over financial  reporting that occurred
               during the small  business  issuer's most recent  fiscal  quarter
               (the small business issuer's fourth fiscal quarter in the case of
               an annual report) that has materially affected,  or is reasonably
               likely to materially affect, the small business issuer's internal
               control over financial reporting; and

5.   The  small  business  issuer's  other  certifying  officer(s)  and  I  have
     disclosed,  based on our most recent  evaluation  of internal  control over
     financial reporting,  to the small business issuer's auditors and the audit
     committee of the small  business  issuer'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  the  small
               business  issuer'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 small business
               issuer's internal control over financial reporting.
