Ally Financial Inc., whose GMAC Mortgage unit halted evictions in 23 states amid allegations of mishandled affidavits, says its filings contained no false claims about home loans.

The “defect” in affidavits used to support evictions was “technical” and was discovered by the company, Gina Proia, an Ally spokeswoman, said in an e-mailed statement. Employees submitted affidavits containing information they didn’t personally know was true and sometimes signed without a notary present, according to the statement. Most cases will be resolved in the next few weeks and those that can’t be fixed will “require court intervention,” Proia said.

“The entire situation is unfortunate and regrettable and GMAC Mortgage is diligently working to resolve the situation,” Proia said. “There was never any intent on the part of GMAC Mortgage to bypass court rules or procedures. Nor do these failures reflect any disrespect for our courts or the judicial processes.”

State officials are investigating allegations of fraudulent foreclosures at the nation’s largest home lenders and loan servicers. Lawyers defending mortgage borrowers have accused GMAC and other lenders of foreclosing on homeowners without verifying that they own the loans. In foreclosure cases, companies commonly file affidavits to start court proceedings.

“All the banks are the same. GMAC is the only one who’s gotten caught,” said attorney Patricia Parker. “This could be huge.”

Florida Attorney General William McCollum is investigating three law firms that represent loan servicers in foreclosures, and are alleged to have submitted fraudulent documents to the courts, according to an Aug. 10 statement. The firms handled about 80 percent of foreclosure cases in the state, according to a letter from Rep. Alan Grayson, D-Fla.
