Reinsurance broker Guy Carpenter has released aÃ‚ briefing on the threat of errors & omissions (E&O) litigation on U.S. real estate professionals. To more accurately gauge the likelihood of litigation Guy Carp has developed its own subprime E&O litigation index. The index measures a combination of factors influencing the E&O litigation climate including foreclosure rate, subprime mortgage delinquency rate, litigation attorneys per mortgage professional, truth in lending legislation and banking litigation ranking. According to the index, Illinois, Michigan and Massachusetts claim the highest overall E&O litigation risk levels, with Mississippi, Indiana and Ohio close behind. The study throws up an interesting fact: there is little to no correlation between the highest risk states for subprime-related E&O litigation and those states such as Arizona and Nevada with the greatest number of subprime mortgage delinquencies and/or foreclosures. Guy Carp also notes that the riskiest states are those with average rankings in most categories and an extremely high result in a single category.
