In the Florida courtroom of Chief Judge Victor Tobin, there's been a marked change the past month in the pace of foreclosures that mortgage companies ask him to approve. Tobin had been handling up to 200 cases a day in which delinquent borrowers weren't contesting mortgage servicers' motions seeking court approval to repossess their homes. Now, it's about 50 a day. That's not the only difference the state judge has noticed in the wake of revelations since September that some mortgage servicers did not follow legal procedures in tens of thousands of foreclosures. In contested cases now, servicers are filing new affidavits stating that they or their lawyers have reviewed supporting documents — language missing in prior affidavits, says Tobin, chief judge of the Broward County Circuit Court.
