Lawyers whose clients refuse to pay their fees routinely file lawsuits and win judgments against them. But attorney Ellen Marshall’s disputes with a former divorce client have been anything but routine.Then again, Warren Matthei is no ordinary client.

Matthei, a millionaire stockbroker from Summit, N.J., spent nearly a decade in jail — first for refusing to pay child support to his ex-wife and later for refusing to pay Marshall’s attorney fees.Marshall obtained an $85,000 judgment against Matthei, but court records show she has all but given up on getting the money from Matthei.
