Dear Sirs:

RE:     REGISTRATION STATEMENT ON FORM S-8

The following opinion is furnished to you in connection with the filing by
Amdocs Limited (the "Company") of its registration statement on Form S-8 (the
"Registration Statement"), under the Securities Act of 1933, as amended,
relating to the registration of 4,179 of its ordinary shares, (Pound
Sterling)0.01 par value (the "Shares"), subject to awards pursuant to the Cramer
Y Share Scheme (the "Plan"), which was assumed by the Company in connection with
its August 14, 2006 acquisition of Cramer.

In that connection, we have examined originals, or copies certified or otherwise
identified to our satisfaction, of all such documents, corporate records and
other instruments as we have deemed necessary or appropriate for the purposes of
this opinion, including the Plan, Articles of Association and Memorandum of
Association of the Company.

Based upon such examination, we are of opinion that:

      1.    The Company has been duly organized and validly exists as a
            corporation under the laws of Guernsey, Channel Islands.

      2.    When issued and sold upon the exercise of options granted or
            pursuant to awards made in accordance with the terms of the Plan as
            contemplated by the Registration Statement, each of the Shares will
            be validly issued, fully paid and non-assessable.

We express no opinion on any law other than the law of Guernsey as of the date
hereof.

We hereby consent to the use of this opinion as an exhibit to the Registration
Statement.

Yours faithfully,


/s/ Carey Olsen
