In a probate proceeding, Richard Feigen's children allege that his will offered for probate, which was prepared by Zabel and Schulte Roth & Zabel, was the product of undue influence and fraud by Mr. Feigen's third wife.

Discovery produced by Feigen's surviving spouse showed that while Feigen was alive, the firm was in direct communication with his third wife, who the firm did not represent at the time, about decedent's estate plan. It was also revealed that, before decedent died, firm name partner William Zabel made additions and deletions to a physician's letter concerning decedent's mental capacity, anticipating that such a letter would be used by decedent's spouse in a future probate contest.
