CALIFORNIA FAMILY CODE
UNIFORM CHILD CUSTODY JURISDICTION AND ENFORCEMENT ACT
Family Code Section 3427
(a) A court of this state that has jurisdiction under this part to make
a child custody determination may decline to exercise its jurisdiction
at any time if it determines that it is an inconvenient forum under the
circumstances and that a court of another state is a more appropriate
forum. The issue of inconvenient forum may be raised upon motion of a
party, the court's own motion, or request of another court.
(b) Before determining whether it is an inconvenient forum, a court of
this state shall consider whether it is appropriate for a court of another
state to exercise jurisdiction. For this purpose, the court shall allow
the parties to submit information and shall consider all relevant factors,
(1) Whether domestic violence has occurred and is likely to continue in
the future and which state could best protect the parties and the child.
(2) The length of time the child has resided outside this state.
(3) The distance between the court in this state and the court in the state
that would assume jurisdiction.
(4) The degree of financial hardship to the parties in litigating in one
forum over the other.
(5) Any agreement of the parties as to which state should assume jurisdiction.
(6) The nature and location of the evidence required to resolve the pending
litigation, including testimony of the child.
