CALIFORNIA CODE OF CIVIL PROCEDURE
SERVICE UPON ATTORNEY
C.C.P. Section 1011
The service may be personal, by delivery to the party or attorney on whom
the service is required to be made, or it may be as follows:
(a) If upon an attorney, service may be made at the attorney's office,
by leaving the notice or other papers in an envelope or package clearly
labeled to identify the attorney being served, with a receptionist or
with a person having charge thereof. When there is no person in the office
with whom the notice or papers may be left for purposes of this subdivision
at the time service is to be effected, service may be made by leaving
them between the hours of nine in the morning and five in the afternoon,
in a conspicuous place in the office, or, if the attorney's office
is not open so as to admit of that service, then service may be made by
leaving the notice or papers at the attorney's residence, with some
person of not less than 18 years of age, if the attorney's residence
is in the same county with his or her office, and, if the attorney's
residence is not known or is not in the same county with his or her office,
or being in the same county it is not open, or a person 18 years of age
or older cannot be found at the attorney's residence, then service
may be made by putting the notice or papers, enclosed in a sealed envelope,
into the post office or a mail box, subpost office, substation, or mail
chute or other like facility regularly maintained by the Government of
the United States directed to the attorney at his or her office, if known
and otherwise to the attorney's residence, if known. If neither the
attorney's office nor residence is known, service may be made by delivering
the notice or papers to the address of the attorney or party of record
as designated on the court papers, or by delivering the notice or papers
to the clerk of the court, for the attorney.
(b) If upon a party, service shall be made in the manner specifically provided
in particular cases, or, if no specific provision is made, service may
be made by leaving the notice or other paper at the party's residence,
between the hours of eight in the morning and six in the evening, with
some person of not less than 18 years of age. If at the time of attempted
service between those hours a person 18 years of age or older cannot be
found at the party's residence, the notice or papers may be served
by mail. If the party's residence is not known, then service may be
made by delivering the notice or papers to the clerk of the court, for
that party.
