The wife of Eric Butler, a former Credit Suisse Group AG (CSGN) broker convicted in a $1 billion fraud, is protesting the government’s efforts to take over joint assets, according to a federal court filing.

Elizabeth Butler objected today to a recommendation that the proceeds of joint accounts go to the government to satisfy a $5 million fine and $250,000 forfeiture order. Eric Butler began serving a five-year sentence in September for crimes associated with misleading clients about securities investments.
