Clearing the pipeline in New Jersey, which like New York handles foreclosures through the courts, would take 49 years. In Florida, Massachusetts and Illinois, it would take a decade.

In the 27 states where the courts play no role in foreclosures, the pace is much more brisk — three years in California, two years in Nevada and Colorado — but the dynamic is the same: the foreclosure system is bogged down by the volume of cases, borrowers are fighting to keep their houses and many lenders seem to be in no hurry to add repossessed houses to their books.

“If you were in foreclosure four years ago, you were biting your nails, asking yourself, ‘When is the sheriff going to show up and put me on the street?’ ” said Herb Blecher, an LPS senior vice president. “Now you’re probably not losing any sleep.”

When major banks acknowledged last fall that they had been illegally processing foreclosures by filing false court documents, they said that any pause in repossessions and evictions would be brief. All of the major servicers agreed to institute reforms in their foreclosure procedures. In April, the Office of the Comptroller of the Currency and other regulators gave the banks 60 days to draw up a plan to do so.

But nothing is happening quickly. When the comptroller’s deadline was reached last week, it was extended another month.

New foreclosure cases and repossessions are down nationally by about a third since last fall, LPS said. In New York, foreclosure filings are down 85 percent since September, according to the New York State Unified Court System.

Mark Stopa, a St. Petersburg, Fla., specialist in foreclosure defense, has 1,275 clients, up from 350 a year ago. About 75 clients have won modifications, dismissals or sold their properties for less than they owed. All the other cases are pending.

“Banks aren’t even trying to win,” said Mr. Stopa, who charges his clients an annual fee of $1,500.

J. Thomas McGrady, the chief judge of Florida’s Sixth Circuit, which includes St. Petersburg, agreed. “We’re here to do what we’re asked to do. But you’ve got to ask. And the banks aren’t asking,” he said.

A spokesman for Bank of America said, “Any suggestion that we have a strategy to delay foreclosures is baseless.” A Wells Fargo spokeswoman blamed changes in state laws governing foreclosure for any slowdown. A GMAC spokeswoman said it was following “regulatory and investor expectations.” JPMorgan Chase declined to comment. Servicers said some of the decline in foreclosures could be traced to an improved economy.

There are many reasons that foreclosure, which has been slowing ever since the housing bubble burst, has been further delayed in many states.

The large number of cases nationally — about two million, plus another two million waiting in the wings — have overwhelmed many lenders and the courts.

Lenders, who service loans they own as well as those owned by investors, tried to circumvent the time-intensive process by using “robo-signers” who mass-produced documents, many of which made inaccurate claims. When the bad practices were discovered last fall, the lenders were forced to revisit hundreds of thousands of cases.

Over the last two years, most defaulting homeowners were people who had lost their jobs. Housing analysts say these homeowners are more likely to hire a lawyer and fight repossession than borrowers who had subprime loans that swelled beyond their ability to pay.

Judges these days are also more inclined to scrutinize requests for eviction rather than automatically approve them. The so-called foreclosure mills — law firms that handled many of the suits for the banks — are in retreat under law enforcement pressure. And some analysts suggest that banks are reluctant to take too many houses onto their books at any one moment for fear of flooding a shaky market.

In New York, lenders seeking to repossess face additional hurdles. The legislature has mandated that borrower and bank meet to discuss terms under the auspices of the court, but these conferences have turned out to be anything but brief or simple. Instead of one conference, 10 are often needed, court officials say.
