Re:

Deutsche Mortgage & Asset Receiving Corporation
Commercial Mortgage Pass-Through Certificates
Registration Statement on Form SF-3

Ladies and Gentlemen:

We have acted as counsel to Deutsche Mortgage & Asset Receiving Corporation, a Delaware corporation (the “Registrant”), in connection with the preparation of the Registrant’s Registration Statement on Form SF-3 (the “Registration Statement”) relating to the issuance from time to time of the Registrant’s commercial mortgage pass-through certificates (the “Certificates”) in one or more series (each, a “Series”). The Registration Statement is being filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (the “Act”). As described in the Registration Statement, Certificates of each Series will be issued, and will evidence interests in a trust fund established, under a separate pooling and servicing agreement (a “Pooling and Servicing Agreement”) between the Registrant, the trustee named therein and (if applicable) one or more additional parties identified in the prospectus relating to such Series (the related “Prospectus”).

In connection with the foregoing, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we deemed necessary for the purposes of this opinion letter. In our examination, we have assumed the following: (a) the genuineness of all signatures; (b) the legal capacity of natural persons; (c) the authenticity of all documents submitted to us as originals; (d) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such documents; (e) the conformity of the text of each document filed with the Commission through its Electronic Data Gathering, Analysis and Retrieval System to the printed documents reviewed by us; and (f) the truth, accuracy and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates that we have reviewed. As to any facts material to the opinions expressed herein that were not known to us, we have relied upon (1) certificates, statements and representations of officers and other representatives of the Registrant and others

and (2) a certificate of the Secretary of State of the State of Delaware as to the good standing of the Registrant, dated October 14, 2021 (the “Delaware Good Standing Certificate”).

In rendering this opinion, we have further assumed that: (i) the Pooling and Servicing Agreement with respect to each Series of Certificates is executed and delivered substantially in the form filed as an exhibit to the Registration Statement; and (ii) the transactions contemplated to occur under the Registration Statement, the related Prospectus with respect to each Series of Certificates and the related Pooling and Servicing Agreement with respect to each Series of Certificates in fact occur in accordance with the respective terms thereof.

Based upon and subject to the foregoing, we are of the opinion that—

A. When (i) the Registration Statement has become effective, (ii) the issuance and principal terms of any Series of Certificates have been duly authorized by all necessary action by the Registrant, (iii) the Pooling and Servicing Agreement relating to such Series has been duly authorized by all necessary action and executed and delivered by or on behalf of each party thereto, and (iv) the Certificates of such Series have been duly executed, authenticated and delivered in accordance with the terms and conditions of the Pooling and Servicing Agreement relating to such Series and sold in the manner described in the Registration Statement, in any amendment thereto and in any Prospectus relating to such Series, then the Certificates of such Series will be legally and validly issued and outstanding, fully paid and non-assessable.

B. The description set forth under the caption “Material Federal Income Tax Considerations” in the Registration Statement, although it does not discuss all federal income tax consequences that may be applicable to the individual circumstances of particular investors (some of which may be subject to special treatment under the Internal Revenue Code of 1986 (the “Code”)), otherwise correctly describes the material aspects of the federal income tax treatment of an investment in a Series of Certificates commonly applicable to investors that are U.S. Persons (as defined in the Registration Statement) and, where expressly indicated therein, to investors that are not U.S. Persons. We also hereby confirm the opinion expressly set forth under such captions as our opinion.

C. Based solely on the Delaware Good Standing Certificate, the Registrant is validly existing and in good standing under the laws of the State of Delaware.

The opinion set forth in paragraph B above is limited to the United States federal income tax matters specifically covered thereby, and we have not been asked to address, nor have we addressed, any other tax consequences regarding the transaction referred to above or any other transaction. The opinion set forth in paragraph B above is rendered as of the date

In giving such consent, we do not consider that we are “experts” within the meaning of the term as used in the Act or the rules and regulations of the Commission issued thereunder, with respect to any part of the Registration Statement, including this opinion letter as an exhibit or otherwise.

We express no opinion as to any laws other than the federal laws of the United States of America, the laws of the State of New York and, solely with respect to the opinion set forth in paragraph (C) above, the Delaware General Corporation Law. We do not express any opinion, either implicitly or otherwise, on any issue not expressly addressed above.
