What if a lender requirement conficts with state law

This is an excerpt from a recent article by Jeremy Yohe of ALTA:

“Some national lenders are now requiring in their master service agreements adherence to a six-month data retention policy. This means that all data provided to support a transaction must be disposed of within six months after a transaction closes.”

Has anybody seen this?  If so, how does this align with the NJ requirement to save files for 14 years?
