OKLAHOMA CITY (AP) - Oklahomans who lost their homes to foreclosure or were harmed by deceptive banking practices during the nation's housing crisis have until Thursday to apply for part of an $18.6 million settlement with the nation's largest lenders.

More than 326 mortgage-related complaints already have been filed with Oklahoma's attorney general's office, and more are expected this week as the deadline nears.

Some of the practices banks engaged in that are covered under the settlement include robo-signing, where signatures were applied to documents without proper oversight, or dual-tracking, which involves banks guiding homeowners on adjusting mortgages while at the same time pushing ahead with foreclosure. Any homeowners who believe their foreclosure or loan modification involved unfair practices are being urged to apply.
