Heller Ehrman’s creditors now want $150 million from former partners, contending in a confidential mediation brief that the firm fraudulently conveyed that much to partners after it had become insolvent. Meanwhile, a group of 89 former Heller partners said in their own confidential brief that they have hired John Keker of Keker & Van Nest to represent them if creditors pursue a fraudulent conveyance suit.

The documents come to light as Heller’s creditors and former partners prepared for their first mediation conference last week with Judge Randall Newsome of the U.S. Bankruptcy Court for the Northern District of California.
