A bankruptcy trustee in Houston has sued Baker Botts, Paul, Weiss, Rifkind, Wharton & Garrison and Nielsen IP Law, seeking to recover more than $3.6 million in “fraudulent and preferential transfers” that Houston debtor QAI paid for legal services for the debtor’s owner before QAI’s Chapter 7 filing.

The trustee, Christopher Murray, alleges in separate complaints filed on Friday in U.S. District Court for the Southern District of Texas that the legal services the firms provided were of little or no benefit to QAI.
