Homeowners with mortgages serviced by Residential Capital LLC want to form an official committee in the company's bankruptcy case, which would give them a louder voice in the company's complicated chapter 11 proceedings, Dow Jones Newswires reported yesterday. In court filing on Friday, a lawyer for the group of homeowners said they are concerned that state and federal settlements this year with mortgage servicers including ResCap's government-owned parent Ally Financial might not be enforced properly now that ResCap is in bankruptcy. The settlement, over borrower claims of improper foreclosure practices, offers billions of dollars in relief to many homeowners who either owe more than their homes are worth or were forced to sell their homes and move.
