The Board issued final rules to implement a statutory amendment to TILA requiring that consumers receive notice when their mortgage loan has been sold or transferred. The disclosure requirement became effective in May 2009 upon enactment of the Helping Families Save Their Homes Act, which requires the purchaser or assignee that acquires a mortgage loan to provide the required disclosures in writing within 30 days. To provide compliance guidance and greater certainty on the new requirements, the Board published interim rules in November 2009 that were effective immediately, and to allow time to make any necessary operational changes, covered parties are permitted to continue to follow the November 2009 interim rules until the mandatory compliance date for the final rules, which is January 1, 2011.
