A group backed by employees of TransPerfect Global Inc. is pressing the Delaware Court of Chancery to release details of how the custodian overseeing the company’s court-ordered sale has spent more than $18 million in fees and expenses.

The group, Citizens for a Pro-Business Delaware Inc., announced Tuesday that it had filed a motion asking the court to unseal documents relating to at least 32 confidential transactions undertaken by Skadden, Arps, Slate, Meagher & Flom partner Robert B. Pincus since he was appointed custodian in March 2015.
