The Bank of New York Mellon, as Trustee of
Guggenheim Defined Portfolios, Series 1325
MLP & ENERGY FUNDS PORTFOLIO, SERIES 10
2 Hanson Place
Brooklyn, New York 11217


Ladies and Gentlemen:

     We are acting as your counsel in connection with the execution and delivery
by you of a certain Reference Trust Agreement (the "Trust Agreement"), dated as
of today's date between Guggenheim Funds Distributors, LLC, as Depositor (the
"Depositor"), and you, as Trustee, establishing Guggenheim Defined Portfolios,
Series 1325; MLP & ENERGY FUNDS PORTFOLIO, SERIES 10 (the "Trust"), and the
execution by you, as Trustee under the Trust Agreement, of receipts for units
evidencing ownership of all of the units of fractional undivided interest (such
receipts for units and such aggregate units being herein respectively called
"Receipts for Units" and "Units") in the Trust, as set forth in the prospectus
(the "Prospectus"), included in the registration statement on Form S-6, as
amended to the date hereof (the "Registration Statement"), relating to the
Trust. The Trust consists of equity and/or debt securities (the "Securities")
(including delivery statements relating to contracts for the purchase of certain
Securities not yet delivered and cash, cash equivalents or an irrevocable letter
or letters of credit, or a combination thereof, in the amount required to pay
for such purchases upon the receipt of such Securities) as listed under
"Portfolio" in the Prospectus (such Securities, delivery statements and cash,
cash equivalents, letter or letters of credit being herein called the "Portfolio
Assets").

     We have examined the Trust Agreement, and originals (or copies certified or
otherwise identified to our satisfaction) of such other instruments,
certificates and documents as we have deemed necessary or appropriate for the
purpose of rendering this opinion. In such examination, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals and the conformity to the original documents of all documents
submitted to us as copies. As to any facts material to our opinion, we have,
when relevant facts were not independently established, relied upon the
aforesaid instruments, certificates and documents.

     Based on the foregoing, we are of the opinion that:

     1.   The Bank of New York Mellon is a corporation organized under the laws
          of the State of New York with the powers of a trust company under the
          Banking Law of the State of New York.

     2.   The Trust Agreement is in proper form for execution and delivery by
          you, as Trustee, and each has been duly executed and delivered by you,
          as Trustee, and assuming due authorization, execution and delivery by
          the Depositor, the Trust Agreement is a valid and legally binding
          obligation of The Bank of New York Mellon.

     3.   The Receipts for Units are in proper form for execution by you, as
          Trustee, and have been duly executed by you, as Trustee, and pursuant
          to the Depositor's instructions, the Trustee has registered on the
          registration books of the Trusts the ownership of the Units by Cede &
          Co., as nominee of The Depository Trust Company where it has caused
          the Units to be credited to the account of the Depositor.

     In rendering the foregoing opinion we have not considered, among other
things, the merchantability of the Portfolio Assets, whether the Portfolio
Assets have been duly authorized and delivered or the tax status of the
Portfolio Assets under any federal, state or local laws.

     The foregoing opinions are limited to the laws of the State of New York and
the federal laws of the United States of America. This opinion is for your
benefit and may not be disclosed to or relied upon by any other person without
our prior written consent.

     We hereby consent to the filing of this opinion letter as an exhibit to the
Registration Statement relating to the Units and to the use of our name and the
reference to our firm in the Registration Statement and in the Prospectus.


                                                               Very truly yours,

                                                        /s/ Dorsey & Whitney LLP
