         Re:      Registration Statement on Form S-8
                  231,437 Shares of Common Stock
Gentlemen:

         We are special counsel to Bank West Financial  Corporation,  a Michigan
corporation (the  "Corporation"),  in connection with the preparation and filing
with the  Securities and Exchange  Commission  pursuant to the Securities Act of
1933, as amended,  of a  Registration  Statement on Form S-8 (the  "Registration
Statement"),  relating  to the  registration  of up to 231,437  shares of common
stock, par value $.01 per share ("Common  Stock"),  to be issued pursuant to the
Corporation's 1995 Key Employee Stock  Compensation  Program and 1995 Directors'
Stock Option Plan (collectively, the "Plans") upon the exercise of stock options
and/or  appreciation  rights (referred to as "Option Rights").  The Registration
Statement also registers an indeterminate  number of additional shares which may
be necessary under the Plans to adjust the number of shares reserved thereby for
issuance as the result of a stock split, stock dividend or similar adjustment of
the outstanding Common Stock of the Corporation. We have been requested by the

Corporation  to  furnish  an  opinion  to be  included  as  an  exhibit  to  the
Registration Statement.

         For this  purpose,  we have  reviewed the  Registration  Statement  and
related  Prospectus,  the Amended and  Restated  Articles of  Incorporation  and
Bylaws of the Corporation,  the Plans, a specimen stock  certificate  evidencing
the  Common  Stock of the  Corporation  and such  other  corporate  records  and
documents as we have deemed appropriate.  We are relying upon the originals,  or
copies certified or otherwise  identified to our satisfaction,  of the corporate
records  of  the  Corporation  and  such  other  instruments,  certificates  and
representations  of  public  officials,  officers  and  representatives  of  the
Corporation as we have deemed relevant as a basis for this opinion. In addition,
we have  assumed,  without  independent  verification,  the  genuineness  of all
signatures  and  the  authenticity  of all  documents  furnished  to us and  the
conformance  in all respects of copies to originals.  Furthermore,  we have made
such factual  inquiries  and reviewed  such laws as we determined to be relevant
for this opinion.

         For purposes of this opinion,  we have also assumed that (i) the shares
of Common Stock  issuable  pursuant to Option Rights  granted under the terms of
the Plans will  continue to be validly  authorized on the dates the Common Stock
is issued pursuant to the Option Rights; (ii) on the dates the Option Rights are
exercised,  the  Option  Rights  granted  under  the  terms  of the  Plans  will
constitute  valid,  legal and binding  obligations of the  Corporation  and will
(subject to applicable bankruptcy,  moratorium,  insolvency,  reorganization and
other laws and legal  principles  affecting  the  enforceability  of  creditors'
rights  generally) be enforceable as to the Corporation in accordance with their
terms; (iii) no change occurs in applicable law or the pertinent facts; and (iv)
the provisions of "blue sky" and other securities laws as may be applicable will
have been complied with to the extent required.

         Based on the  foregoing,  and  subject  to the  assumptions  set  forth
herein,  we are of the  opinion as of the date  hereof that the shares of Common
Stock to be issued  pursuant to the Plans,  when issued and sold pursuant to the
Plans and upon receipt of the consideration  required  thereby,  will be legally
issued, fully paid and non-assessable shares of Common Stock of the Corporation.

         We hereby  consent  to the  reference  to this firm  under the  caption
"Legal Opinion" in the  Prospectuses for the two Plans and to the filing of this
opinion as an exhibit to the Registration Statement.

                                      Very truly yours,

                                      ELIAS, MATZ, TIERNAN & HERRICK L.L.P.
