215 ILCS 5/1306

If Illinois residents whose loans are serviced outside Illinois are involved in a group-to-group consolidation by an out-of-state servicer, Section 1305 may be employed if the Illinois residents are an incidental part of the consolidation. Otherwise the provisions of this Article shall apply to any consolidation insofar as it involves Illinois residents. For purposes of this provision "incidental" shall mean that the Illinois residents comprise less than 25% or 100 lives of the total lives involved in the consolidation, whichever is less.
