Distinguish enforcement from modification. ## Working notes California’s act begins with [[Cal. Fam. Code § 5700.101]]. A [[Child Support]] order may be registered for enforcement without transferring authority to change it. Residence, consent, and the controlling order matter in [[Interstate Cases]]. The [[Noncustodial Parent (NCP)]]’s move does not itself transfer jurisdiction. Spousal support has a separate continuing-jurisdiction rule. The [[Custodial Parent (CP)]] label alone does not establish the controlling order or modification jurisdiction. > [!tip] Comparison > [[Uniform Child Custody Jurisdiction Enforcement Act (UCCJEA)|UCCJEA]] concerns custody and parenting time, not the support amount.
