"Support order" means a judgment or order of support in favor
of an obligee, whether temporary or final, or subject to
modification, termination, or remission, regardless of the kind of
action or proceeding in which it is entered. For the purposes of
Section 685.020 of the Code of Civil Procedure, only the initial
support order, whether temporary or final, whether or not the order
is contained in a judgment, shall be considered an installment
judgment. No support order or other order or notice issued, which
sets forth the amount of support owed for prior periods of time or
establishes a periodic payment to liquidate the support owed for
prior periods, shall be considered a money judgment for purposes of
subdivision (b) of Section 685.020 of the Code of Civil Procedure.
