      ------------------------------------       

Gentlemen:


  We are acting as special counsel to Citizens Utilities Company, a Delaware
corporation (the "Company" or "Citizens"), in connection with the preparation
of the above Registration Statement filed with the Securities and Exchange
Commission ("Commission") under the Securities Act of 1933 (the "Act"), of
up to $201,250,000 Convertible Preferred Securities ("Convertible Preferred
Securities") of Citizens Utilities Trust (the "Trust"), Partnership Preferred
Securities ("Partnership Preferred Securities") of Citizens Utilities Capital
L.P., ("Citizens Capital"), Convertible Subordinated Debentures ("Convertible
Debentures") of Citizens, Common Stock of Citizens ("Common Stock") to be
issued upon conversion of the Convertible Debentures ("Conversion Common
Stock"), Common Stock of Citizens to be issued in payment of dividend or
distribution requirements ("Distribution Common Stock"), the Guarantee by
Citizens with respect to Convertible Preferred Securities ("Trust
Guarantee"), and the Guarantee by Citizens with respect to Partnership
Preferred Securities ("Partnership Guarantee") to be issued and sold from
time to time under the Act.  The Conversion Common Stock, Distribution Common
Stock, Trust Guarantee, Partnership Guarantee and Convertible Debentures are
herein referred to as the "Citizens Securities".  The Convertible Preferred
Securities, Partnership Preferred Securities, Limited Partnership Agreement
of Citizens Capital, Declaration of Trust of the Trust, Convertible
Debentures, Trust Guarantee and Partnership Guarantee, taken as a whole,
constitute a full and unconditional guarantee of amounts due under the
Convertible Preferred Securities, and the opinions of our firm and of
Skadden, Arps, Slate, Meagher & Flom as to the components of such full and
unconditional guarantee constitute an opinion as to such guarantee.  With
respect to matters relating to the Convertible Preferred Securities,
Partnership Preferred Securities, Declaration of Trust of the Trust and
Limited Partnership Agreement of the Partnership we are relying on the
opinion of even date of Skadden, Arps, Slate, Meagher & Flom being filed as
Exhibit 5.2 to the Registration Statement which covers the Trust, the Trust
Securities, the Partnership and the Partnership Preferred Securities.

  In this connection, we have examined the registration statement on Form S-3
(the "Registration Statement") filed on October 23, 1995 and Amendment No.
1 thereto filed on November 30, 1995 under the Act, including the prospectus
which is a part thereof, the exhibits filed therewith and such other
documents as we have considered necessary for the purposes of this opinion. 
Based upon such examination and subject to the foregoing and other
qualifications and limitations expressed herein.  In our examination, we have
assumed the legal capacity of all natural persons, the genuiness of all
signatures, the authenticity of all documents submitted to us as originals,
the conformity to original documents of all documents submitted to us as
certified or photostatic copies and the authenticity of the originals of such
copies.  In addition, we have assumed that the Underwriting 

                                 2

Agreement, Indenture and Guaranties as executed will be in the form reviewed by
us as of the date hereof.  As to any facts material to the opinions expressed
herein which were not independently established or verified, we have relied
upon oral or written statements and representations of officers, trustees and
other representatives of the Company, the Trust, the Partnership and others. 
We hereby advise you that:

    (1)  We are of the opinion that the Company is a corporation validly
organized and duly existing under the laws of the State of Delaware.  We are
further of the opinion that, if and when an offering of Company Securities
shall be made from time to time in accordance with the Registration
Statement, as amended and supplemented from time to time, and when the steps
enumerated in Paragraph (2) hereof shall have been taken and the conditions
satisfied as of the date of issuance, the Company Securities (other than the
Distribution Common Stock as to which we are opining separately) will, when
sold, be, (a) if such securities are shares, legally issued, fully paid and
non-assessable shares of Common Stock, and, (b) if such securities are debt
securities, validly issued and binding obligations of the Company.

    (2)  The steps which are referred to in the foregoing Paragraph (1)
hereof are:

         order approving and authorizing the issuance of the Company
         Securities and such order shall be in full force and effect; and the
         order of the Arizona Corporation Commission waiving jurisdiction
         over the affiliated transactions aspects of the

         Commission and any other governmental regulatory authority in the
         State of Louisiana with respect to the issuance and sale of Offered 
         Securities shall have been issued and shall be in full force and
         effect at the time of such issuance and sale of the Company 
         Securities;

                                     4

         jurisdiction;

         (g) An appropriate order of the West Virginia Public Service

         been issued as of the date hereof) and shall be in full force and
         effect at the time of such issuance and sale of the Company
         Securities, or it shall be determined that the West Virginia 

                                 5
   
         Public Service Commission shall be without jurisdiction;

         (h) An appropriate order of the Federal Energy Regulatory Commission

         shall have been issued (which order has been obtained as of the date
         hereof) and shall be in full force and effect;

         (i) An appropriate order of, or exemption from the jurisdiction of,
         any other regulatory body which in the future may assert
         jurisdiction over the Company securities shall be in existence;

         (j) The applicable provisions of the Act shall have been complied
         with;

         (k) The Company and reserved for issuance Securities shall have been
         duly authorized by the Board of Directors, and duly executed and

         steps necessary to reserve adequate authorized shares for issuance
         shall have been taken;

         (l) The Indenture relating to the Convertible Debentures shall have
         been duly authorized by the Board of Directors, executed and
         delivered; and a supplemental indenture thereto shall have been duly

         in accordance with the terms of said Indenture;
  
         (m) The Indenture (as supplemented), the 

                                  6

         Trust Guarantee, Partnership Guarantee and the Convertible Preferred 
         Securities shall have been qualified under the Trust Indenture Act 
         of 1939;

         in accordance with terms of said Indenture, as supplemented; and

         (o) The Company Securities shall have been duly issued and paid for.
 

  With respect to the Distribution Common Stock, we are of the opinion that,
(a) subject to the satisfaction of each of the foregoing conditions with
respect to the Distribution Common Stock at the time of each issuance of
Distribution Common Stock and (b) the corporate authorization of additional
shares of Common Stock under the Company's Certificate of Incorporation, as
required, and (c) with respect to Distribution Common Stock to be issued more
than two years after the date hereof compliance with the registration
requirements of the Act and appropriate orders of the regulatory bodies
referred to above (which have not been sought or obtained as of the date
hereof), such Company securities will be legally issued, fully paid and
nonassessable Common Stock of the Company.  

  In rendering the foregoing opinion we express no opinion as to laws other
than the laws of the State of New York, the corporation laws of the State of
Delaware and the Federal laws of the United States, and to a limited extent
the laws of the States mentioned below.  To the extent that the foregoing
opinions relate to the laws of the State of Delaware as applied to the Trust,
the Convertible Preferred Securities, the Partnership and the Partnership
Preferred Securities we have relied on the opinion of even date of Skadden,

laws of the States of Arizona, Colorado, Hawaii, Louisiana, Tennessee,
Vermont and West Virginia with respect to regulatory
