                      Re: Morgan Stanley Capital Trust VI

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for Morgan Stanley
Dean Witter & Co., a Delaware corporation (the "Company"), and Morgan Stanley
Capital Trust VI, a Delaware business trust (the "Trust"), in connection with
the matters set forth herein. At your request, this opinion is being furnished
to you.

                  For purposes of giving the opinions hereinafter set forth,
our examination of documents has been limited to the examination of originals
or copies of the following:

                  (a) The Certificate of Trust of the Trust, dated as of
September 24, 2001 (the "Certificate"), as filed in the office of the Secretary
of State of the State of Delaware (the "Secretary of State") on September 24,
2001;

                  (b) The Trust Agreement of the Trust, dated as of September
24, 2001, by and among the Company, the administrators of the Trust named
therein and the trustees of the Trust named therein;

                  (c) The Registration Statement (the "Registration Statement")
on Form S-3, including a preliminary prospectus (the "Prospectus"), relating to
the Capital Securities of the Trust representing preferred undivided beneficial
interests in the assets of the Trust (each, a "Capital Security" and
collectively, the "Capital Securities"), as proposed to be filed by the
Company, the Trust and others with the Securities and Exchange Commission on or
about March 1, 2002;

                  (d) A form of Amended and Restated Trust Agreement of the
Trust (including Exhibits A, C and D thereto) (the "Trust Agreement"), to be
entered into among the Company, the administrators of the Trust named therein,
the trustees of the Trust named therein, and the holders, from time to time, of
undivided beneficial interests in the assets of the Trust, filed as an exhibit
to the Registration Statement; and

                  (e)      A Certificate of Good Standing for the Trust, dated
February 27, 2002, obtained from the Secretary of State.

                  Capitalized terms used herein and not otherwise defined are
used as defined in the Trust Agreement.

                  For purposes of this opinion, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that
is inconsistent with the opinions stated herein. We have conducted no
independent factual investigation of our own but rather have relied solely upon
the foregoing documents, the statements and information set forth therein and
the additional matters recited or assumed herein, all of which we have assumed
to be true, complete and accurate in all material respects.

                  With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Trust Agreement constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Trust Agreement and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation or due
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are signatories to the documents examined by
us, (iv) that each of the parties to the documents examined by us has the power
and authority to execute and deliver, and to perform its obligations under,
such documents, (v) the due authorization, execution and delivery by all
parties thereto of all documents examined by us, (vi) the receipt by each
Person to whom a Capital Security is to be issued by the Trust (collectively,
the "Security Holders") of a Capital Securities Certificate evidencing
ownership of such Capital Security and the payment for the Capital Security
acquired by it, in accordance with the Trust Agreement and the Registration
Statement, and (vii) that the Capital Securities are

issued and sold to the Security Holders in accordance with the Trust Agreement
and the Registration Statement. We have not participated in the preparation of
the Registration Statement and assume no responsibility for its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1. The Trust has been duly created and is validly existing in
good standing as a business trust under the Delaware Business Trust Act.

                  2. The Capital Securities will represent valid and, subject
to the qualifications set forth in paragraph 3 below, fully paid and
nonassessable preferred undivided beneficial interests in the assets of the
Trust.

                  3. The Security Holders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Security Holders may
be obligated to make payments as set forth in the Trust Agreement.

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement. In
addition, we hereby consent to the use of our name under the heading "Legal
Matters" in the Prospectus. In giving the foregoing consents, we do not thereby
admit that we come within the category of Persons whose consent is required
under Section 7 of the Securities Act of 1933, as amended, or the rules and
regulations of the Securities and Exchange Commission thereunder. Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.

                                   Very truly yours,


                                   /s/ Richards, Layton & Finger, P.A.
