At least five Am Law 100 firms have landed roles on the $2.9 billion cash-and-stock sale of Lender Processing Services to Fidelity National Financial, the nation’s largest title insurer.

Announced Tuesday, the transaction calls for Jacksonville-based FNF to reacquire a unit it spun off in 2008 that provides technology and data analysis to mortgage and real estate businesses. FNF plans to pay roughly $1.5 billion in cash for LPS, which handles about half of all mortgages in the United States in terms of dollar value, according to Bloomberg.
