The struggling Ruden McClosky law firm filed for bankruptcy protection Tuesday and announced an asset sale agreement with Greenspoon Marder to create a 140-lawyer firm based in Fort Lauderdale.

The law firm merger plan was announced an hour after Ruden filed for Chapter 11 bankruptcy protection, listing assets and liabilities of $10 million to $50 million. Wells Fargo is listed as its largest creditor at $4.6 million.
