It has evolved into one of New York’s longest-running fights over an estate.
For more than a decade, the family of C. C. Wang, a collector whose name graces a gallery at the Metropolitan Museum of Art, has been battling over a trove of classical Chinese paintings and scrolls that has been described as among the finest in the world.
Now, the feud has escalated. In the past month, two of Mr. Wang’s children, who have been fighting in Surrogate’s Court in Manhattan since his death in 2003 at 96, filed lawsuits in state and federal courts accusing each other of looting and deceit.
