Attn:  Board of Directors

         Re:      Registration Statement on Form S-8

Gentlemen:

     In connection  with the  registration  by FileNet  Corporation,  a Delaware
corporation (the "Company") of 2,000,000 shares of Common Stock, par value $0.01
per share (the "Shares"), to be issued pursuant to the Amended and Restated 2002
Incentive  Award Plan of FileNet  Corporation  (the "Plan") under the Securities
Act of 1933, as amended on Form S-8 to be filed with the Securities and Exchange
Commission (the "Registration  Statement"),  you have requested our opinion with
respect to the matters set forth below.

     In our capacity as your counsel in connection  with such  registration,  we
are  familiar  with the  proceedings  taken,  and  proposed to be taken,  by the
Company in connection  with the  authorization,  issuance and sale of the Shares
and, for the purposes of this  opinion,  have assumed such  proceedings  will be
timely completed in the manner presently proposed.

     As such counsel, we have examined such matters of fact and questions of law
considered  appropriate for purposes of rendering the opinions  expressed below.
In our  examination,  we have assumed the  genuineness  of all  signatures,  the
authenticity of all documents  submitted to us as originals,  and the conformity
to authentic original documents of all documents submitted to us as copies. With
your consent we have relied upon  certificates  of an officer of the Company and
others  with  respect  to certain  factual  matters.  We have not  independently
verified such factual matters.

     We are opining  herein as to the effect on the subject  transaction of only
the General  Corporation Law of the State of Delaware,  including  statutory and
reported  decisional law  thereunder,  and we express no opinion with respect to
the  applicability  thereto or the effect thereon of any other laws or as to any
matters of municipal law or any other local agencies within any state.

     Subject to the foregoing and in reliance  thereon,  it is our opinion that,
upon the  issuance  and sale of the  Shares in the  manner  contemplated  by the
Registration Statement and in accordance with the terms of the Plan, and subject
to the Company completing all action and proceedings  required on its part to be
taken prior to the issuance of the Shares  pursuant to the terms of the Plan and
the  Registration  Statement,  including,  without  limitation,   collection  of
required payment for the Shares,  the Shares will be validly issued,  fully paid
and nonassessable securities of the Company.

     We consent to your  filing this  opinion as an exhibit to the  Registration
Statement.

                                     Very truly yours,


                                     /s/ Latham and Watkins LLP

                CONSENT OF INDEPENDENT REGISTERED ACCOUNTING FIRM
