Dear Sir or Madam:
This opinion is furnished in connection with
the notice (the "Notice") to be filed by Merrill
Lynch California Municipal Series Trust, a
Massachusetts business trust (the "Trust"), with
the Securities and Exchange Commission
pursuant to Rule 24f-2 under the Investment
Company Act of 1940, as amended. The
Notice is being filed to make definite the
registration under the Securities Act of 1933,
as amended, of 3,120,495 shares of beneficial
interest, par value $0.10 per share, of the Trust
(the "Shares") which were sold during the
Trust's fiscal year ended August 31, 1995.
The Shares consist of 2,443,010 shares of
beneficial interest of Merrill Lynch California
Insured Municipal Bond Fund (the "California
Insured Fund") and 677,485 shares of

<PAGE>
Fund (the "California Fund").
The California Insured Fund and the California
Fund are the two existing series of the Trust.
As counsel for the Trust, we are familiar with
the proceedings taken by it in connection with
the authorization, issuance and sale of the Shares.
In addition, we have examined and are familiar
with the Declaration of Trust of the Trust, the
By-Laws of the Trust and such other documents
as we have deemed relevant to the matters
referred to in this opinion.
Based upon the foregoing, we are of the
opinion that the Shares were legally issued, fully
paid and non-assessable.
In rendering this opinion, we have relied as to
matters of Massachusetts law upon an opinion of
Bingham, Dana & Gould, dated October 19, 1995,
rendered to the Trust.
We hereby consent to the filing of this opinion
with the Securities and Exchange Commission
as an attachment to the Notice.
Very truly yours,
