Chadbourne & Parke has sued a former partner over a fee awarded in a matter involving trusts for descendents of department store magnate Marshall Field.

The suit, filed last week in Manhattan Supreme Court (See Complaint), targets Charles F. Gibbs, a veteran trusts and estates lawyer who left Chadbourne in 2000 to join Holland & Knight. Gibbs had been appointed by Surrogate’s Court as guardian ad litem in the Field matter in 1992. Chadbourne, which continued to provide legal services on the matter after Gibbs left the firm, claims Gibbs refuses to split an $875,000 fee awarded by the court in September 2009.
