Court records show that the amount claimed by Countrywide was from the period during which Ms. Hill was making regular payments under the auspices of the bankruptcy court. They included “monthly charges” totaling $3,840 from November 2006 to April 2007, late charges of $128 and other charges of almost $200.

A lawyer representing Ms. Hill in her bankruptcy case, Kenneth Steidl, of Steidl and Steinberg in Pittsburgh, wrote Countrywide a few weeks later stating that Ms. Hill had been deemed current on her mortgage during the period in question. But in May, Countrywide sent Ms. Hill another notice stating that her loan was delinquent and demanding that she pay $4,715.58. Neither Mr. Steidl nor Julia Steidl, who has also represented Ms. Hill, returned phone calls seeking comment.

Justifying Ms. Hill’s arrears, Countrywide sent her lawyer copies of three letters on company letterhead addressed to the homeowner, as well as to Mr. Steidl and Ronda J. Winnecour, the Chapter 13 trustee for the western district of Pennsylvania.

The Countrywide letters were dated September 2003, October 2004 and March 2007 and showed changes in escrow requirements on Ms. Hill’s loan. “This letter is to advise you that the escrow requirement has changed per the escrow analysis completed today,” each letter began.

But Mr. Steidl told the court he had never received the letters. Furthermore, he noticed that his address on the first Countrywide letter was not the location of his office at the time, but an address he moved to later. Neither did the Chapter 13 trustee’s office have any record of receiving the letters, court records show.

When Mr. Steidl discussed this with Leslie E. Puida, Countrywide’s outside counsel on the case, he said Ms. Puida told him that the letters had been “recreated” by Countrywide to reflect the escrow discrepancies, the court transcript shows. During these discussions, Ms. Puida reduced the amount that Countrywide claimed Ms. Hill owed to $1,500 from $4,700.

Under questioning by the judge, Ms. Puida said that “a processor” at Countrywide had generated the letters to show how the escrow discrepancies arose. “They were not offered to prove that they had been sent,” Ms. Puida said. But she also said, under questioning from the court, that the letters did not carry a disclaimer indicating that they were not actual correspondence or that they had never been sent.
