Jurisdiction usually follows the child’s home state under the UCCJEA, which often means where the child has lived for six months before the case starts. The original issuing state keeps exclusive, continuing jurisdiction until certain conditions are met, such as everyone moving away or losing significant connections. Emergency jurisdiction can exist in another state for safety concerns, but long-term changes still require proper transfer or modification. If you move, talk with counsel before filing so you do not undermine your own case. Keep school records, medical records, and proof of residence to document connections. Colorado’s UCCJEA statutes explain these jurisdiction rules.
