The Thoroughbred Retirement Foundation, based in Lexington, filed suit Thursday against the estate of Thoroughbred breeder Paul Mellon, alleging that the executors slandered the TRF last year, according to the Daily Racing Form.
The Mellon Estate, which has provided $7 million for an endowment, allegedly cost the foundation hundreds of thousands of dollars in donations by hurting the organization's reputation, according to the suit filed in New York.
TRF chairman John Moore told the Daily Racing Form that the foundation decided that it had to sue to clear its name after a letter was sent to the New York Attorney General alleging financial irregularities.
At the time, the office was investigating charges, including those described in a New York Times story, that the foundation had neglected horses in its care.

The foundation, which is designed to care for retired racehorses that can't find new homes, disputes that any horses were neglected.
Moore could not be reached for comment late Thursday.
