Ringtail Solutions, the litigation support systems vendor used by firms such as Lovells, Allen & Overy and Berwin Leighton Paisner, has been acquired by the US-based FTI Consulting, for $35m (£18.3m).

FTI, a large professional services organisation whose business runs from corporate finance and restructuring to litigation consulting, bought the Australian-owned Ringtail after three years of reselling its technology in the US.
