2005 California Probate Code Sections 1610-1611 CHAPTER 3. PERMANENT AND STABLE HOME

1610.  (a) The Legislature finds and declares that it in the best
interest of children to be raised in a permanent, safe, stable, and
loving environment.
   (b) Unwarranted petitions, applications, or motions other than
discovery motions after the guardianship has been established create
an environment that can be harmful to children and are inconsistent
with the goals of permanency, safety, and stability.
1611.  If a person files a petition for visitation, termination of
the guardianship, or instruction to the guardian that is
unmeritorious, or intended to harass or annoy the guardian, and the
person has previously filed pleadings in the guardianship proceedings
that were unmeritorious, or intended to harass or annoy the
guardian, this petition shall be grounds for the court to determine
that the person is a vexatious litigant for the purposes of Title 3a
(commencing with Section 391) of Part 2 of the Code of Civil
Procedure.  For these purposes, the term "new litigation" shall
include petitions for visitation, termination of the guardianship, or
instruction to the guardian.
