Action a State must file under the Uniform Interstate Family Support Act (UIFSA) guidelines when it does not have Long Arm Jurisdiction (I.E., cannot legally claim personal jurisdiction over a non-custodial parent who lives in another State). This is usually in cases where a State is trying to establish an initial child support order on behalf of a resident custodial party. Other actions, such as requesting wage withholding or reviewing and/or revising an existing support order, do not require a Two-State Action even if the initialing State does not have Long Arm Jurisdiction.
