Gentlemen:

          We have acted as counsel to American Physicians Service Group, Inc., a
Texas corporation (the "Company"),  in connection with the registration,  on the
Company's Registration  Statement on Form S-8 (the "Registration  Statement") to
be filed under the Securities Act of 1933, as amended (the "Securities Act"), of
the offer and sale of an aggregate of 400,000 shares of common stock,  par value
$.10 per share,  of the  Company  (the  "Common  Stock"),  as that number may be
adjusted from time to time pursuant to the  provisions of the Company's  Amended
and Restated 1995 Incentive and Non-Qualified Stock Option Plan, as amended (the
"Plan"),  that may be issued pursuant to stock options (the  "Options")  granted
under the Plan.

          In reaching the opinion set forth herein,  this firm has reviewed such
agreements,  certificates  of public  officials  and  officers  of the  Company,
records, documents, and matters of law that this firm deemed relevant, including
(a) the  Registration  Statement,  (b) the Certificate of  Incorporation  of the
Company, (c) the Bylaws of the Company, and (d) the Plan.

         Based upon and  subject to the  foregoing  and  subject  further to the
assumptions,  exceptions,  and  qualifications  hereinafter  stated,  this  firm
expresses the opinion that each share of Common Stock, when issued in accordance
with the terms of the Plan and related option agreement, will be legally issued,
fully paid, and non-assessable.

          The opinion  expressed above is subject to the following  assumptions,
exceptions, and qualifications:

          1. This firm has assumed  that (i) all  information  contained  in all
documents reviewed by this firm is true and correct,  (ii) all signatures on all
documents  reviewed by this firm are genuine,  (iii) all documents  submitted to
this firm as originals  are true and complete,  (iv) all documents  submitted as
copies are true and complete copies of the originals  thereof,  (v) each natural
person  signing any document  reviewed by this firm had the legal capacity to do
so and (vi) each  person  signing  in a  representative  capacity  any  document
reviewed by this firm had authority to sign in such capacity.

         2. This firm has also  assumed  that the Company  has  received or will
receive the full amount and type of consideration  (as specified in the Plan and
each applicable option agreement) for each of the shares of Common Stock or will
have received that  consideration  upon the issuance of Common Stock pursuant to
the applicable  Option,  that such consideration will be either cash or personal
property,  that such  consideration will equal or exceed the par value per 




share of Common Stock, that appropriate certificates evidencing such shares will
be properly executed upon such issuance, and that each grant of an Option 
pursuant to the Plan will be duly authorized.

          The opinions  expressed  above are limited to the laws of the State of
Texas.

         This opinion may be filed as an exhibit to the Registration  Statement.
In giving this  consent,  we do not thereby admit that we come into the category
of persons whose consent is required  under Section 7 of the  Securities  Act or
the rules and regulations of the Securities and Exchange Commission  promulgated
thereunder.

                                Very truly yours,
