Several lawsuits have been in progress arguing that MERS violated state recording statutes by not recording mortgage assignments and thus cheating recording offices out of fees they otherwise would have earned. Interpreting Illinois law, the Seventh Circuit rejected that claim as have other courts that addressed the issue. Union County v. MERSCORP, Inc., 2013 WL 6017394 (7th Cir. 2013) (applying Ill. law). The court explained that Illinois law agrees with almost all other states in providing a voluntary recording system that is intended to protect those who record; that system does not require property transactions to be recorded for them to be valid. It merely protects bona fide purchasers from prior claims against which they had no notice.
