2005 California Civil Code Sections 1812.10 Article 12.3. Actions

1812.10.  (a) An action on a contract or installment account under
this chapter shall be tried in the superior court in the county where
the contract was in fact signed by the buyer, where the buyer
resided at the time the contract was entered into, where the buyer
resides at the commencement of the action, or where the goods
purchased pursuant to the contract have been so affixed to real
property as to become a part of that real property.
   (b) In the superior court designated as the proper court in
subdivision (a), the proper court location for trial of an action
under this chapter is the location where the court tries that type of
action that is nearest or most accessible to where the contract was
in fact signed by the buyer, where the buyer resided at the time the
contract was entered into, where the buyer resides at the
commencement of the action, or where the goods purchased pursuant to
the contract have been so affixed to real property as to become a
part of that real property.  Otherwise, any location of the superior
court designated as the proper court in subdivision (a) is the proper
court location for the trial  of the action.  The court may specify
by local rule the nearest or most accessible court location where the
court tries that type of case.
   (c) In any action subject to this section, concurrently with the
filing of the complaint, the plaintiff shall file an affidavit
stating facts showing that the action has been commenced in a
superior court and court location described in this section as a
proper place for the trial of the action.  Those facts may be stated
in a verified complaint and shall not be stated on information or
belief.  When that affidavit is filed with the complaint, a copy
thereof shall be served with the summons.  If a plaintiff fails to
file the affidavit or state facts in a verified complaint required by
this section, no further proceedings may occur, but the court shall,
upon its own motion or upon motion of any party, dismiss the action
without prejudice.  The court may, on terms that are just, permit the
affidavit to be filed subsequent to the filing of the complaint and
a copy of the affidavit shall be served on the defendant.  The time
to answer or otherwise plead shall date from that service.
