        Dear Sirs:


                  We have acted as special counsel for you and the other
        Sponsors of Defined Asset Funds - Municipal Investment Trust
        Fund, Monthly Payment Series - 155 (the "Fund"), in connection
        with the issuance of units of fractional undivided interest in
        the Fund (the "Units") in accordance with the related Trust
        Indenture (the "Indenture") with the trustee. The accompanying
        Rule 24f-2 Notice (the "Notice") for the Fund makes definite in
        number the registration of Units sold in reliance upon the Rule
        during the fiscal period covered by the Notice.  The Units
        covered by the Notice are hereinafter referred to as the
        "Registered Units".

             We have examined and are familiar with originals or copies,
        certified or otherwise identified to our satisfaction, of such
        documents and instruments as we have deemed necessary or
        advisable for the purpose of this instrument.

             Based upon the foregoing, we are of the opinion that the
        Registered Units, assuming due execution and delivery of any
        certificates evidencing the Registered Units by the Sponsors and
        the Trustee and assuming payment for all registered Units in
        accordance with the Indenture, have been legally issued and are
        fully-paid and non-assessable.

                                           Very truly yours,


                                           Davis Polk & Wardwell
