If a petition, an order, or another document to be submitted to the court is one for which the Judicial Council has adopted a mandatory form, that form must be used. Except as provided in this rule, if the Judicial Council has adopted a mandatory form in more than one alternative version, one of the alternative versions must be used. If that form is inadequate in a particular situation, an addendum may be attached to it.
The following forms have been adopted by the Judicial Council as alternative mandatory forms for use in probate proceedings or other proceedings governed by provisions of the Probate Code:
((Subd (b) amended effective January 1, 2021; adopted effective January 1, 2007; previously amended effective January 1, 2010, and January 1, 2014.))
Notwithstanding any other provision of this rule, a party petitioning for appointment of a temporary guardian of the person of a minor may file either form GC-110 or form GC-110(P). A party petitioning for appointment of a general guardian of the person of a minor may file either form GC-210 or form GC-210(P). A party petitioning for appointment of a temporary guardian of the estate or the person and estate of a minor must file form GC-110. A party petitioning for appointment of a general guardian of the estate or the person and estate of a minor must file form GC-210.
