California Welfare and Institutions Code Section 750
Welfare and Institutions Code section 750 provides in relevant part:
"Whenever a petition is filed in the juvenile court of a county other than the residence of the person named in the petition, . . . the entire case may be transferred to the juvenile court of the county wherein such person then resides at any time after the court has made a finding of the facts upon which it has exercised its jurisdiction over such minor, and the juvenile court of the county wherein such person then resides shall take jurisdiction of the case upon the receipt and filing with it of such finding of the facts and an order transferring the case." For purposes of this provision, "the residence of the minor is the residence of the person legally entitled to custody of the minor." (In re Judson W. (1986) 185 Cal.App.3d 838, 843.)
Rules 5.610 and 5.612 of the California Rules of Court implement section 750. Rule 5.610 provides for the procedure and conduct of the transfer-out hearing.
Subdivision (e) of that rule provides:
"After the court determines the identity and residence of the child's custodian, the court must consider whether transfer of the case would be in the child's best interest. The court may not transfer the case unless it determines that the transfer will protect or further the child's best interest." (Cal. Rules of Court, rule 5.610(e); see also In re R.D. (2008) 163 Cal.App.4th 679, 687 "At a transfer-out hearing, the transferring court is required to make findings not only as to the child's residence, but also whether the transfer is in the child's best interests".)
Rule 5.612 provides for the procedure and conduct of the transfer-in hearing. Subdivision (a)(1) of that rule provides that "the receiving court must accept jurisdiction of the case" and "may not reject the case." (Cal. Rules of Court, rule 5.612(a)(1); see also In re R.D., at p. 684.)
