For some Florida residents, the price of getting out of foreclosure will include taking on a second mortgage — payable this time to their lawyers.

The new mortgage, which takes effect only if the foreclosure is dismissed and the homeowner’s debt to the bank is reduced, is controversial among defense lawyers, some of whom call it “creepy” and “crass.” Yet even they acknowledge it offers a solution to a vexing question: How do they get paid?

After recent revelations that banks were sloppy in processing many foreclosures and in some cases lack standing to seize a house, potential clients seeking to challenge their lenders are flocking to lawyers. But while these distressed homeowners might have a case, they generally lack the resources to pay legal fees. Being in foreclosure usually means being broke.

“We thought, ‘Why don’t we use a bit of ingenuity to find an affordable way to represent them?’ ” said Peter Ticktin of the Ticktin Law Group in Deerfield Beach, Fla. “It’s a new model, a new paradigm.”

Foreclosure defense is a new legal specialty whose strategies and techniques are still being worked out. Mr. Ticktin, who has some 3,000 foreclosure clients, says his plan to collect fees by taking another mortgage on his clients’ properties has already been copied by other firms.

The Ticktin mortgages resemble the loans that the clients originally got from Countrywide, GMAC and other lenders. Each will be a contractual obligation with the law firm, labeled as a mortgage and structured like one, too, with the client paying a certain sum every month and using the house as collateral.

Unconventional payment structures are becoming popular in the foreclosure hotbed of Florida. Whether they yet have caught on elsewhere is unclear. Certainly, Mr. Ticktin is far from the only lawyer being forced to innovate.

fine them.
