While many UK law firms are investing in and deploying legal technology, only a few are sure of its financial impact on their bottom line, according to the “Is Your Tech Smart?” survey.

The survey, conducted by LexisNexis of 91 midlevel U.K. law firms with less than $35 million in annual revenue, found that 24 percent of respondents increased their tech spend by up to 10 percent over the past three years, though nearly all, 87 percent, believed their law firm technology contributed “some extent” to their firms profit growth.
