2009 California Civil Code - Section 2342-2345 :: Article 4. Obligations Of Agents To Third Persons

2342.  One who assumes to act as an agent thereby warrants, to all
who deal with him in that capacity, that he has the authority which
he assumes.

2343.  One who assumes to act as an agent is responsible to third
persons as a principal for his acts in the course of his agency, in
any of the following cases, and in no others:
   1. When, with his consent, credit is given to him personally in a
transaction;
   2. When he enters into a written contract in the name of his
principal, without believing, in good faith, that he has authority to
do so; or,
   3. When his acts are wrongful in their nature.

2344.  If an agent receives anything for the benefit of his
principal, to the possession of which another person is entitled, he
must, on demand, surrender it to such person, or so much of it as he
has under his control at the time of demand, on being indemnified for
any advance which he has made to his principal, in good faith, on
account of the same; and is responsible therefor, if, after notice
from the owner, he delivers it to his principal.

2345.  The provisions of this Article are subject to the provisions
of Part I, Division First, of this Code.
