Richard W. Fields says he has come up with a win-win financial strategy for the downturn. He is investing in lawsuits.

Not in trip-and-fall cases, mind you, but in disputes that are far larger, more costly and potentially more lucrative, often pitting major corporations against each other.

Mr. Fields is chief executive of Juridica Capital Management. which runs a fund that invests in one side of a lawsuit in exchange for a share of any winnings.

“It’s always a good time to invest in litigation,” Mr. Fields said, though he added that the weak economy helped. “When the recession started to bite, the phones started ringing off the hook. Last year, we looked at 122 cases and we made 17 investments.” A small but growing number of investors are exploring this idea, helping companies avoid some of the risks and costs of litigation in exchange for part of any money paid out when the case is settled or resolved by a court. After all, it can be costly to hire lawyers, who may charge close to $1,000 an hour at the most elite firms.
