DENMARK, Me. — The house that set off the national furor over faulty foreclosures is blue-gray and weathered. The porch is piled with furniture and knickknacks awaiting the next yard sale. In the driveway is a busted pickup truck. No one who lives there is going anywhere anytime soon.

Nicolle Bradbury bought this house seven years ago for $75,000, a major step up from the trailer she had been living in with her family. But she lost her job and the $474 monthly mortgage payment became difficult, then impossible.

It should have been a routine foreclosure, with Mrs. Bradbury joining the anonymous millions quietly dispossessed since the recession began. But she was savvy enough to contact a nonprofit group, Pine Tree Legal Assistance, where for once in her 38 years, she caught a break.

Her file was pulled, more or less at random, by Thomas A. Cox, a retired lawyer who volunteers at Pine Tree. He happened to know something about foreclosures because when he worked for a bank he did them all the time. Twenty years later, he had switched sides and, he says, was trying to make amends.
